EVACUATION DEVICE WITH A MATTRESS COVER AND A TRAIL RUG
Domain of the invention
The present invention generally relates to a device for evacuating a person. More specifically, this invention relates to an evacuation device comprising a mattress, a mattress cover and a slip blanket, with which rapid and efficient evacuation is possible, in particular in multi-storey nursing homes.
BACKGROUND OF THE INVENTION
There are different types of evacuation devices with which an injured person can be transported, eg after an accident, or to an attack. Some of these evacuation devices have a chassis on wheels, which is particularly useful for transferring a person from an ambulance car to an operating room as quickly as possible. However, such devices are not suitable for transporting people on stairs, and are therefore not suitable for evacuating people from a multi-storey building in the event of an emergency such as fire or explosion, since it is forbidden to use a lift to be used in such cases.
There are other evacuation devices such as a sling (also called a stretcher), with an elongated rectangular shape on which, for example, an injured person can be placed, with two pairs of handles, one at the head end and one at the foot end, with which the sling and the person can be carried by two rescuers or rescue workers. Carrying berries are extremely suitable for freeing injured people from a tunnel, or for transporting injured people over mountains of debris, for example after an earthquake.
However, the present invention particularly relates to an evacuation device for nursing homes such as, for example, hospitals or retirement homes for the elderly, with which bedridden persons (e.g. patients) can be efficiently evacuated in the event of an emergency, preferably as many people as possible in the shortest possible time, and with as few staff as possible, all the more so because, for example, there are usually fewer staff present at night and during the weekend. The inventors have come up with the idea of using the mattress as part of the evacuation device, among other things because bedridden persons usually already lie on a mattress (on a bed), so that these persons in particular can be evacuated very quickly, while they are on the bed. mattress.
AU5656400A describes a known evacuation device 100 as shown in FIG. 1 and FIG. 2, and requires a special mattress with transverse channels through which fixation straps are provided for securing a patient. The mattress is surrounded by a mattress cover with a top on which a patient lies, and with a bottom that can be dragged over the floor. The top and bottom of the mattress cover are with each other by means of a zipper
BE2017 / 5343 connected. Six short carrying loops are provided on the mattress, more specifically one at the head end, one at the foot end, and four at the sides of the mattress, with which the mattress and a patient lying on it can be carried with four people. The carrying loops are sewn to the mattress cover.
WO2008 / 004860A1 describes another known evacuation device 200 with a mattress, and a blanket under the mattress. No fixation straps are provided, but the blanket has flaps that can be folded up for wrapping the patient. To keep the blanket in place during normal use (on a bed of the nursing home), four elastic bands are provided that must be applied over the four corners of the mattress. Furthermore, there is a pull loop provided at the head and foot ends of the blanket that protrudes under the mattress.
There is always room for alternatives and improvements.
Summary of the invention
It is an object of the present invention to provide an evacuation device with which it is possible to evacuate people, in particular bedridden persons, more quickly and / or more efficiently from a multi-storey building.
It is an object of embodiments of the present invention to provide an evacuation device that is better suited to transporting people, even to a lower floor via a staircase, by only one rescuer.
It is an object of embodiments of the present invention to provide an evacuation device with a reduced risk of injuring the patient during the evacuation.
It is an object of embodiments of the present invention to provide an evacuation device with which the risk of loss of time during an evacuation is reduced or minimized.
It is an object of embodiments of the present invention to provide an evacuation device which during normal use (e.g. on a bed of a nursing home, in healthcare or elderly care without calamities) offers largely the same advantages as a traditional mattress and mattress cover (e.g. hygiene, simplicity of making a bed, simplicity of cleaning under the bed, etc.), but which can be transformed into an evacuation device in a minimum of time in case of calamities.
These and other objects are achieved by an assembly, and a set of parts, and a mattress cover and a drag blanket according to the present invention.
In a first aspect, the present invention provides an assembly comprising: a mattress; and a mattress cover that surrounds the mattress; a towing blanket with at least a first towing loop for dragging the towing blanket over a floor; characterized in that the mattress cover and the
BE2017 / 5343 drag blanket can be connected by means of at least a first divisible zipper and a second divisible zipper that both extend in a longitudinal direction of the mattress cover; wherein the first divisible zipper includes a first zipper portion fixedly attached to the mattress cover, and a matching second zipper portion securely attached to the slip blanket, and wherein the second divisible zipper includes a third zipper portion securely attached to the mattress cover, and a fitting fourth zipper section that is firmly attached to the drag blanket.
The mattress cover and the drag blanket are in fact releasably connectable to each other, or in other words releasable and connectable, or also: connectable and releasable.
The slip blanket of the present invention is not part of the mattress cover.
In other words, even without the slip blanket, the mattress cover forms a closed or closable cover suitable for surrounding a mattress. It is an advantage that the bottom of the mattress cover does not have to be dragged over the floor.
The first and third zipper sections are fixedly connected to the mattress cover, for example by sewing, stitching or gluing, or by another fixed connection method.
The second and fourth zipper sections are fixedly connected to the tow blanket, e.g. by sewing, stitching or gluing, or by another fixed connection method.
It is an advantage that the first zipper and the second zipper can form a connection between the mattress cover and the tow blanket, which can be repeatedly attached, and released again, without damaging the connection itself, or the mattress cover or the tow blanket.
It is an advantage that the assembly comprises a slip blanket that can be attached to a mattress cover and not to a mattress itself, because such a mattress cover allows the use of different types of mattress, and which allows the mattress to be protected (e.g. against body moisture), and which washable (hygiene). By providing the zip sections that act as fastening means on the mattress cover instead of on the mattress itself, any mattress that fits into the mattress cover can in principle be used.
It is an advantage to provide a tow blanket that is securely attachable to the mattress cover, so that the tow blanket occupies a suitable and predetermined position with respect to the mattress cover.
It is an advantage of the tow blanket according to the present invention that it is attached to the mattress cover almost at all times, both during normal use of the mattress (for supporting a patient on a bed) and during an evacuation. This offers the advantage over drag blankets stored in a cupboard that no time will be lost to search for, unfold, and possibly attach to the mattress during an emergency situation. This saves valuable time.
It is an advantage to connect the tow blanket with at least two sturdy zippers to the mattress cover, as this ensures a strong connection between the tow blanket and the mattress cover, which ensures that the tow blanket and the mattress cover remain interconnected,
BE2017 / 5343 even during an evacuation, when maneuvering firmly between a door and dragging over a staircase. It will be clear that other connecting means such as rubber bands that are placed around the corners of the mattress cover to supposedly hold a (tow) blanket in place, or Velcro (e.g. Velcro), will immediately come off as soon as the least force is exerted on the (tow) blanket. In other words, such rubber bands or velcro straps are absolutely not suitable for keeping a mattress in place during towing.
A further advantage of the zipper between the mattress cover and the tow blanket is that it prevents the tow blanket from folding or rolling up or crumpling under the mattress cover, or even getting entangled with the bed base. This in turn prevents valuable time being lost in an evacuation, to first release the tow blanket from the bed base, then stretch it and attach it to the mattress cover. By the way, because the zippers ensure that the drag blanket stays in place with respect to the mattress, hospital staff are better motivated to secure it properly, because this helps to make a bed faster, and it also gives a more comfortable mind or feeling that everything is ready in case of emergency.
On the other hand, it is an advantage that the mattress cover and the slip blanket are releasable from each other, because this in turn allows the mattress cover and the slip blanket to be manufactured separately. This makes it possible to use different materials for the mattress cover and the drag blanket, so that the properties of both can be optimized.
It is an advantage to use divisible zippers, wherein the mattress cover and the drag blanket each contain a part of the divisible zipper, because this allows the mattress cover and the drag blanket to be completely separated from each other. As a result, the mattress cover and the drag blanket can, for example, easily be cleaned separately or even be replaced.
It is an advantage to attach the mattress cover and the tow blanket to each other by means of a zipper that extends in the longitudinal direction of the mattress cover, because it forces the forces exerted on the tow blanket during towing over a floor or over a staircase (e.g. (during an evacuation), can be transferred to the mattress cover in a way in which the forces are distributed over the entire length of the zipper.
An additional advantage of a zipper (as opposed to, for example, a connection with a multitude of knots) is that it allows the mattress cover and the drag blanket very quickly over a relatively large distance (e.g. over 50 cm or 60 cm or 70 cm or 80 cm or 90 cm or even 100 cm).
It is an advantage to provide at least one draw loop, because this allows the assembly to be towed (eg over the ground or a floor or a staircase) by a single person.
It is a conceptual advantage that the assembly actually has only two assembled states: (a) a normal state of use, where the assembly acts as a mattress in a mattress cover, (b) an evacuation state, where the assembly serves to keep a person safe to bring. In both cases, the two zippers must be closed completely
BE2017 / 5343. A half-open zipper does not belong. The latter motivates staff to always close the zippers, greatly increasing the chance of rapid evacuation.
The mattress cover may have its own zipper, or other means such as buttons or Velcro or the like to open and close the mattress cover, so that a mattress can be inserted into the mattress cover, and the mattress cover defines substantially a closed space.
In one embodiment, the assembly further comprises at least a first and second fixation strap for fixing a person to the mattress cover, which fixation straps extend in a transverse direction of the mattress cover.
The at least two fixation straps are preferably positioned such that a person can be fixed to the assembly at the height of the chest and at the height of the legs. As a result, the chance of the person shifting relative to the assembly is minimal, as well as the chance of injuries during towing. This also makes it possible for a person lying on his or her side to be evacuated in that position, which is not possible with some other systems.
The first and second fixation belts are preferably located at a distance of at least 50 cm and at most 100 cm from each other.
In one embodiment, the first and second fixation straps are fixedly connected to the tow blanket, e.g. by sewing or stitching or gluing, or in some other way.
The first and second fixation belts can be made of the same material as the material used for car safety belts. This is a very sturdy material that can support enormous tensile forces, allowing a patient to be securely attached to the mattress or mattress cover so that he or she will take a fixed position with respect to the mattress or mattress cover, even when assembled through a corridor and / or is dragged down a staircase.
In one embodiment, the first and the second fixation strap each comprise a buckle and a tensioning system, and the buckle of each fixation strap comprises a snap mechanism.
In this way the person can be fixed very quickly and efficiently, without complicated actions, which is important in emergency situations, when action must be taken quickly and fairly impulsively.
The buckle can for instance be made from plastic and / or from metal. Buckles are known in various embodiments. A type of buckle that is very suitable for the present invention is a type in which a first split body has two outwardly resilient parts that can be inserted into a slot of a second split body. Such type is used, for example, with child seats, but other types of buckles can also be used.
In one embodiment, each buckle comprises a first and a second split body, the first split body being attached to a first end of the fixation belt, and the second split body being attached to a second end of the fixation belt; and the assembly further comprises at least four elastic bands, each for receiving one split body.
BE2017 / 5343
The first slit body may have a slit, and the second slit body may, for example, have at least two protruding parts that can be inserted into the slit of the first slit body.
In one embodiment, at least two of the split bodies have a concave shape with rounded corners.
This increases the chance that the split bodies stay in place relative to the elastic bands, without considerably hampering or preventing pulling out of the fixation straps.
In one embodiment, the at least four elastic bands are positioned with respect to an edge of the drag blanket, and the first and second spliced body of the first and second fixation strap are positioned relative to the fixation strap such that the ends of the fixation straps protrude beyond a peripheral edge of the towing blanket, over a distance in the range of 5 to 30 cm, preferably in the range of 10 to 25 cm, e.g. over a distance of about 15 cm, or about 20 cm.
This offers the advantage that one can quickly grasp the fixation straps. Tests have shown that, thanks to the retractable straps, the fixation of a patient is up to 50% faster, among other things because one can immediately grasp the straps because they protrude outside of the assembly, and therefore do not first have to push the edge of the mattress to cancel. This also has the important advantage that the patient does not have to be turned or shifted, so that pain can be avoided. In other words, the fixation straps ensure that the patient can be evacuated as painlessly as possible, in the position he was in before the evacuation, for example on his / her back or on his / her side. During evacuation, the protrusions can be pulled out quickly, so that the buckle, which was held or stored in its elastic band, comes out and is visible for fixing.
In one embodiment, the first and second and third and fourth zipper sections are in a zone between the first and the second fixation belt.
It is an advantage that the zipper sections are located between the fixation straps, so not beyond the fixation straps, because this allows storage or grabbing of the fixation straps without having to (partially) open the zippers. This saves time, and simplifies the use of the assembly.
In one embodiment, the first and second and third and fourth zipper sections extend over at least 80% of the distance between the first and second fixation belts, preferably over at least 85% or at least 90% of this distance.
It is an advantage to attach the mattress cover and the tow blanket to each other by means of a zipper which extends in the longitudinal direction of the mattress cover, because it forces the forces exerted on the tow blanket when dragging over a floor or over a staircase (e.g. (during an evacuation), can be transferred to the mattress cover in a way in which the forces are distributed over the entire length of the zipper. By dividing these forces over
BE2017 / 5343 at a relatively large distance, stress concentrations are avoided or reduced, and the risk of overloading and damage to the zipper, and thus the risk of the mattress cover and the slip blanket becoming detached during an evacuation (eg on a staircase) is strongly reduced or even completely excluded. This benefit cannot be underestimated. Imagine how much time will be lost, and what reaction this will cause in the emergency workers, should the mattress cover and the slip come loose from each other, when dragging on the stairs, in case of fire.
The fixation belts are preferably arranged close to or substantially against the zipper ends. As a result, the power of towing is largely absorbed by these strong fixation bands. This also creates more stability when dragging a patient away.
In one embodiment, the first draw loop is located at the head end or at the foot end of the mattress cover.
It is an advantage that the pull loop is located at the head end or foot end of the mattress or mattress cover, since this allows the assembly to be moved by a single person, the assembly being moved in its longitudinal direction, thereby reducing the risk of obstacles and hence delay is minimized. In particular, maneuvering through a doorway or along a staircase becomes easier and faster this way.
It should be noted in this regard that the forces to which the zipper sections are subjected when pulling on the pull loop are mainly shear forces between the zipper section of the mattress cover and the zipper section of the drag blanket, but zippers are resistant to it, in contrast to forces which the two zipper parts would pull apart in a transverse direction, but such forces do not or hardly ever occur, thanks to the positioning of the pull loop and / or of the fixation straps (if present).
In one embodiment, the assembly further comprises a second pull loop, wherein one of the first and second pull loop is located at the head end of the mattress cover, and the other of the first and second pull loop is located at the foot end of the mattress cover.
By providing a pull loop at both the head end and the foot end, the assembly can, in the event of an evacuation, be dragged very quickly to one direction or the other, without first having to turn the mattress. This saves valuable time.
The pull loop at the head and foot can also be used to evacuate heavier people by two people.
In one embodiment, the assembly further comprises a third draw loop which is located at the same end of the mattress cover as the first draw loop, and which has a length of 30% to 70% of the length of the first draw loop, and the assembly further comprises a fourth draw loop located at the same end of the mattress cover as the second draw loop, and having a length of 30% to 70% of the length of the second draw loop.
BE2017 / 5343
The first and third pull loop can have a common part. In other words, the third draw loop can be formed by providing an intermediate connection between two points of the first draw loop.
Similarly, the second and fourth draw loops may have a common portion, and the fourth draw loop may be formed by providing an interconnection between two points of the second draw loop.
In this embodiment, the assembly thus has a (relatively) short and a (relatively) long pull loop. Preferably, the length of the long pull loop is chosen such that the assembly can be easily dragged by a single person of average length (from, for example, 160 to 180 cm), without having to walk down. Because the rescue worker can walk or walk upright, a lot of time can be saved, and towing is much less tiring, so that the same rescue worker can save several bedridden people. An advantage of the short draw loop is that it allows maneuvering the assembly through a door or in a stairwell very quickly and conveniently.
In one embodiment, the slip blanket is substantially in the shape of an octagon; wherein the octagon comprises a first zone with the shape of a rectangle with two opposite sides on which or alongside or adjacent to which the third and fourth zipper sections are located, and wherein the octagon comprises a second and a third zone with a tapered or conical shape, the first zone is between the second and third zones; and wherein the octagon has a reinforced circumference; and wherein peripheral segments of the second tapered or conical zone are substantially in line with the first draw loop when it is tensioned from a middle position thereof in a direction away from the tow blanket; and wherein peripheral segments of the third tapered or conical zone are substantially in line with the second draw loop when it is tensioned from a middle position thereof in a direction away from the tow blanket.
The tapered or conical zone of the towing blanket preferably has a trapezoidal shape.
It is an advantage to provide the tow blanket with a reinforcement edge, because larger forces can thereby be transferred from the tow loop to the tow blanket without it stretching or tearing.
It is a great advantage that the draw loop is in line with the circumferential segments of the tapered or conical, e.g. trapezoidal portion, because this greatly reduces the risk of coming loose from the draw loop of the tow blanket, in particular near the place where the draw loop is attached to the tow blanket.
In one embodiment, the first and the second draw loop form an integral part of the reinforced circumference.
As a result, the chance of coming loose from the first and second pull loop is virtually non-existent because they form an integral part of it.
BE2017 / 5343
In one embodiment, the assembly further comprises a first storage bag situated between the mattress cover and the tow blanket, and attached to the tow blanket or to the mattress cover, an entrance of which is situated between the connection points of the first draw loop.
This first storage bag offers the advantage that the first draw loop, and if present also the third draw loop, can be neatly stowed therein, so that it cannot protrude along the side between the mattress cover and the slip blanket, and get stuck to the bed base.
The first storage bag is ideal for storing the first and, if present, the third draw loop, for daily use of the assembly (ie during normal use in a hospital, for example). This prevents nuisance from making the bed, and minimizes the risk that the pull loops get entangled with the base of the bed, or with the fixation straps. The storage bag can thus prevent valuable time from being lost during an evacuation, and can prevent frustration among hospital staff because the pull loops have been given a fixed place and not get in the way during normal use.
In one embodiment, the assembly further comprises a first Velcro connection with at least a first Velcro strip fixedly attached to the mattress cover and with at least a second Velcro strip fixedly attached to the tow blanket, the Velcro connection being located between connection points of the first draw loop and oriented in a transverse direction of the mattress cover.
It is an advantage of such a Velcro that under normal use of the assembly it can hold the draw loop in place by slightly clamping it between the Velcro straps, and that it opens automatically during an evacuation if the draw loop is pulled with sufficient force.
Preferably a first Velcro is provided at the level of the first pull loop (e.g. at the head end), and a second Velcro is provided at the height of the second pull loop (e.g. at the foot end).
This Velcro fastener further ensures that the trapoidal zone is fixed at the head or foot end of the drag blanket and remains in place relative to the mattress cover. This is especially advantageous with adjustable beds, because then the assembly is not always located in a horizontal plane. The Velcro ensures that also the head end and foot end of the sliding blanket cannot shift relative to the mattress cover.
In case the tow blanket has an octagonal shape, then this first Velcro (e.g. Velcro) is preferably at the tapered end.
If a first storage bag is present, then this first Velcro can also ensure that this storage bag is fully or partially closed, so that the first draw loop also stays in place.
The velcro strip can be one continuous strip, or can comprise two zones where the mattress cover and the slip blanket engage with each other, and comprise an intermediate (e.g. bare) zone
BE2017 / 5343 where the mattress cover and the drag blanket do not interfere with each other, but through which the first pull loop can protrude. As a result, a portion of the first draw loop remains visible and can be reached from outside. Moreover, in this case the storage bag will open automatically when the projecting loop end is pulled. This makes super fast evacuation possible.
In one embodiment, the assembly further comprises a second storage bag, situated between the mattress cover and the tow blanket, and attached to the tow blanket or to the mattress cover, an entrance of which is situated between the connection points of the second draw loop.
The same advantages as for the first storage bag and the first draw loop apply.
In one embodiment, the assembly further comprises a second Velcro connection, located between the connection points of the second pull loop.
The same benefits as for the first storage pouch and the first Velcro strap apply, but now for the second pull loop.
In one embodiment, the slip blanket comprises a coating applied to the plane of the slip blanket which, when the slip blanket and the mattress cover are attached to each other by means of the first and second zipper, faces the mattress cover.
Tests have surprisingly shown that thanks to this coating the sliding is considerably better, presumably because this makes the sliding blanket a bit tighter, but the inventors do not want to be bound by any theory.
In one embodiment, the coating is a PES FR 20 type, commercially available from Vetex N.V., Leon Bekaertstraat 14, B 8770 Ingelmunster, Belgium. Tests have shown that an assembly with such a coating can slide much easier than known devices without such a coating.
In a second aspect, the present invention provides a set of components, comprising: a mattress cover and a corresponding slip blanket with the features stated in the first aspect.
The present invention also seeks protection for a loose mattress cover and a corresponding slip blanket, even if they are not (yet) attached to each other.
In a third aspect, the present invention provides a mattress cover suitable for forming an assembly according to the first aspect, or as part of the set of parts according to the second aspect, wherein the mattress cover forms an enclosure for receiving a mattress; and wherein the mattress cover comprises a first zipper portion of a first divisible zipper, which first zipper portion is fixedly attached to the mattress cover, and extends in a longitudinal direction of the mattress cover, but wherein the mattress cover does not have a suitable second zipper portion; and wherein the mattress cover comprises a third zipper portion of a second divisible zipper, which third zipper portion is fixedly attached to the mattress cover, and extends in a longitudinal direction of the mattress cover, but wherein the mattress cover does not have a suitable fourth zipper portion, and wherein the first zipper portion and
BE2017 / 5343 the third zipper portion is on opposite sides of the mattress cover, and wherein the first zipper portion and the third zipper portion have a length that is 30% to 70% or 40% to 60% of the length of the mattress cover.
In a fourth aspect, the present invention provides a tow blanket suitable for forming an assembly according to the first aspect, or as part of the set of parts according to the second aspect, wherein the tow blanket comprises a zipper portion of a first divisible zipper, which zipper portion is fixed is attached to the tow blanket and extends in a longitudinal direction of the tow blanket; and wherein the tow blanket comprises a zipper portion of a second divisible zipper, which zipper portion is fixedly attached to the tow blanket, and extends in a longitudinal direction of the tow blanket; and wherein the zipper portion of the first divisible zipper and the zipper portion of the second divisible zipper are on opposite sides of the slip blanket; and wherein the zipper portion of the first divisible zipper and the zipper portion of the second divisible zipper have a length that is 30% to 70% or 40% to 60% of the length of the tow blanket.
Specific and preferred aspects of the invention are included in the appended independent and dependent claims.

It can therefore be interpreted as specifying the presence of the listed characteristics, values, steps or components referred to, but does not exclude the presence or addition of one or more other characteristics, values, steps or components, or groups thereof. Thus, the scope of the expression a device comprising means A and B should not be limited to devices that only switch off
BE2017 / 5343 components A and B exist. It means that with respect to the present invention, A and B are the only relevant components of the device.
In the present invention, the terms zipper and zipper are used as synonyms.
In the present invention, the terms slip and slip are used as synonyms.
In the present invention, the term releasably attachable means that two objects can be coupled to each other in a simple manner and repeatedly and can be disconnected again, without significant wear or damage. More specifically, in the context of the present invention, a divisible zipper with two zipper parts or a Velcro with two Velcro strips is considered a releasable attachment, but a fastening attachment is considered a fixed attachment.
The term divisible zipper means a zipper with two elongated parts that can be fully detached and separated from each other, in contrast to a non-divisible zipper, where the zipper parts are always in engagement with each other at one end.
The present invention generally relates to a device for evacuating a person. More specifically, this invention relates to an evacuation device comprising a mattress, a mattress cover and a slip blanket, with which rapid and efficient evacuation is possible, in particular in multi-storey nursing homes. In the event of an emergency, for example a fire on the fifth floor, it is important to be able to bring as many people as possible to safety as quickly as possible and with as few staff as possible. Since it is forbidden to use the lift in such situations, it is important that the evacuation device is able to evacuate people via the stairs.
To this end, the present invention provides an assembly 1 comprising a mattress 4, a mattress cover 2, and a slip blanket 3. The tow blanket 3 has at least one draw loop 61, situated at the head or foot end of the assembly or the mattress, for dragging the assembly 1 over a floor.
Some examples of evacuation devices known in the art have already been described in the background section, and are shown in FIG. 1 to FIG. 3. However, these systems have a number of disadvantages.
According to an important underlying principle of the present invention, the mattress cover 2 and the slip blanket 3 can be coupled to each other by means of at least a first divisible zipper 71 (see e.g. FIG. 20) and a second divisible zipper 72, both extending into the longitudinal direction X of the mattress cover 2.
As shown in FIG. 20, the first divisible zipper 71 includes a first zipper portion 711 fixedly attached to the mattress cover 2, and a second zipper portion 712 fixedly attached to the drag blanket 3 and matching the first zipper portion.
BE2017 / 5343
Similarly, the second divisible zipper 72 includes a third zipper portion
721 fixedly attached to the mattress cover 2, and a fourth zipper portion 722 fixedly attached to the slip blanket 3 and matching the third zipper portion 721. As shown in FIG. 5, the first zipper portion 711 and the second zipper portion 721 are on opposite sides of the mattress cover 2, and as can be understood from FIG. 9, the third zipper portion 712 and the fourth zipper portion are located
722 located on opposite sides of the tow blanket 3.
The zip sections 711, 712, 721, 722 can, for example, be sewn or stitched to the slip blanket 3 or the mattress cover 2. Thanks to the divisible zippers 71, 72, the mattress cover 2 can be completely separated from the slip blanket 3, eg when the mattress cover must be washed or must be repaired. However, it is intended that the slip blanket and mattress cover are firmly connected to each other when a patient is lying on the mattress, such that the slip blanket and mattress cover are already correctly positioned relative to each other before a disaster occurs, but especially that mutual position is also maintained when the whole (tow blanket + mattress cover + mattress + patient) is lifted off the bed, and is dragged down corridors and through doorways and over a staircase. As far as known to the inventors, this combination, and in particular a mattress cover with two zip sections and an associated drag blanket with two corresponding zip sections, is not offered by existing systems.
As will be further explained in more detail, in preferred embodiments of the assembly 1 according to the present invention, additional provisions have been made which both benefit the use of the assembly during normal use on a bed (inter alia by causing as little inconvenience as possible). (both for the patient and for the staff), as well as for use during evacuation (ao firmness, handy towing, handy maneuvering) In this way the assembly 1 according to the present invention provides an ideal compromise for both situations: both normal use (on a bed) and during an emergency (on the floor).
Tests have shown that it is also a great reassurance for caregivers to know that the assembly is literally ready for use in an emergency. This is a strong motivator to use the assembly correctly (for example, by storing the pull loop (s) 61, 62 and / or the fixation straps 51, 52 correctly), because it both hinders when cleaning the room, whether bed making is minimized, as well as valuable time will be gained in the event of an evacuation.
We now refer to the figures.
FIG. 1 and FIG. 2 is a replica of FIG. 1 and FIG. 2 from AU5656400A, and show an evacuation device 100 known in the art. This device has already been discussed in the background selection, and is primarily intended as a mattress, with a patient typically by four
BE2017 / 5343 people is being relocated. A loop is provided at the head and foot ends, but these are far too short to be able to drag the mattress quickly and efficiently over a distance of, for example, at least 5 meters, and their attachment is also not suitable for being able to drag the mattress down a staircase. There is a particularly high chance that the loop will come loose, and / or that the bottom of the mattress cover will tear when this loop is pulled firmly.
FIG. 3 is a replica of FIG. 6 from WO2008 / 004860A1 and shows a schematic representation of another evacuation device known in the art. This device was also discussed in the background section. One of the problems with this device is that, during normal use in a nursing home, the underside thereof does not stay in place, and is therefore not correctly positioned in case of an emergency.
FIG. 4 to FIG. 30 show various aspects of a preferred embodiment of an assembly 1 according to the present invention. However, not all of these aspects need to occur together in embodiments of the present invention, even though they are usually shown together in the figures. Embodiments of the present invention have the features as defined in the claims. The figures serve to illustrate these characteristics.
FIG. 4 shows a perspective view of a preferred embodiment of an assembly 1 according to the present invention. The assembly 1 comprises (at the bottom and barely visible in FIG. 4) a tow blanket 3, with a mattress cover 2 attached thereto which is attached to the tow blanket 3 by means of at least two zippers 71, 72. These zippers are an essential part of the evacuation device of the present invention, and will be further explained in more detail.
The assembly 1 of FIG. 4 is better visible in FIG. 8, where it is shown upside down, with the mattress cover 2 at the bottom and the drag blanket 3 at the top, for illustrative purposes. But this is not the position in which assembly 1 is to be used, either during care or during an evacuation.
The assembly 1 of FIG. 4 further comprises at least one pull loop 61, but preferably two pull loops, namely a first pull loop 61 at the head end and a second pull loop 62 at the foot end of the assembly 1, which pull loops are shown in FIG. 4 are largely in a retracted or stowed position, but deliberately protrude a little beyond assembly, so that they can be grabbed quickly. The selective removal and storage thereof will be further described in more detail.
The assembly 1 of FIG. 4 preferably further comprises two fixation straps 51, 52, which are shown in the representation of FIG. 4 are also largely in their retracted position between the mattress cover 2 and the drag blanket 3, but the fixation belts also deliberately protrude slightly beyond the
BE2017 / 5343 assembly 1, so that they can be grabbed quickly. An exemplary manner for storing the fixation straps 51, 52 will be described in more detail in FIG. 21 to FIG. 24.
Furthermore, FIG. 4 that the mattress cover 2 preferably has its own zipper T1, (more clearly visible in FIG. T1 to FIG. 29), which zipper is preferably covered by a border 28. If the zipper T1 of the mattress cover 2 is a watertight zipper, the border 28 may possibly be omitted, but of course it is also possible to provide both a watertight zipper T1 and a border 28. In this way it is possible to avoid or at least greatly reduce the risk that body fluids which would end up on the mattress cover 2, the mattress cover can penetrate and foul the mattress 4 inside it.
In preferred embodiments, the assembly 1 has a first axis of symmetry LL in the longitudinal direction X of the mattress, and a second axis of symmetry DD in a transverse direction Y of the mattress, apart from the presence of an optional label or label 91, and apart from the closing direction of the zippers 71, 72, and the like. The assembly may, for example, contain a label 91 on which the care institution can, for example, state a date. The label 91 can be fused. The position of the label 91, if present, can be used, for example, to ensure that the same side of the assembly is always used as headboard or footboard respectively. The substantially symmetrical construction offers the advantage that the assembly (in an evacuation) can be towed in the same way, both in the direction of the foot end and in the direction of the head end, with the same advantages, and with the same strength properties.
Comparative tests conducted at a University Hospital have shown that with an assembly 1 shown in FIG. 4 roughly takes only half as much time to drag a person through a corridor, through two doors, and via a staircase one floor below, compared to existing towing systems, and that moreover only one rescuer is needed instead of several rescuers. In concrete terms, this means that assembly 1 according to the present invention makes it possible to evacuate more patients within a certain time and with a given staffing. Or to put it differently, the assembly 1 according to the present invention makes it possible to evacuate a given number of patients with a given staffing, in less time.
FIG. 5 is a schematic representation of a preferred embodiment of the tow blanket 3 as may be used in the assembly 1 of FIG. 4. The towing blanket 3 shown has an octagonal shape with a middle (rectangular) zone 31, and with two tapered, e.g. trapezoidal zones 32, 33. The zones are shown in different hatching for illustrative purposes, but in practice these form zones preferably one continuous whole. The circumference of the octagon is preferably completely or largely surrounded by a reinforcement edge or reinforcement band 37 (see FIG. 12).
BE2017 / 5343
The length of the drag loops 61, 62 (measured from their connection points 612, 613) with the reinforcement edge of the octagon) and the angles α formed by the oblique segments 35a, 35b of the trapezoidal zone 32 are preferably matched to each other such that the drag loops 61, 62 (in their extended position) are in line with the oblique peripheral segments 35a, 35b. As a result, stress concentrations, especially at the connection points 612, 613, are largely avoided during towing.
The zipper portions 711, 721 fixedly attached to the tow blanket 3, e.g. by sewing, and forming part of the zippers 71, 72 with which the tow blanket 3 and the mattress cover 2 are attached or coupled to each other are shown with a thick black stripe for illustrative purposes.
The fixation straps 51, 52 (at least a part thereof) are also shown. These extend in a transverse direction Y with respect to assembly 1, and are e.g. sewn or stitched or glued to the drag blanket 3, and are located on a top thereof in FIG. 5, so that they will not interfere with towing, and cannot catch on anything. This aspect is more visible in FIG. 21, where assembly 1 is shown upside down (with the mattress cover 2 at the bottom), and the slip blanket 3 is partially folded for illustrative purposes. The seams 513 with which the fixation straps are sewn to the slip blanket 3 are clearly visible in FIG. 21.
Preferably, the length of the slip blanket 3 is substantially the same as that of the mattress cover 2, or is at most 10 cm smaller, or at most 6 cm smaller. Preferably, the width of the drag blanket 3 is also substantially the same as that of the mattress cover 2, or is at most 6 cm smaller. As a result, the friction between the assembly 1 and the floor over which the assembly is dragged during an evacuation is largely determined by the properties of the slip blanket 3 and only to a very limited extent by the properties of the mattress cover 2 (in particular only at the corners).
The drag blanket 3 is preferably coated with a coating such that dragging the assembly requires very little effort, even when the assembly is being pulled by a single person. The coating can be a multi-layer coating, e.g. with an anti-bacterial layer and with a fire-resistant layer.
However, contrary to what one might suspect, this coating is preferably not applied on the side that comes into contact with the floor during an evacuation, but on the side that is in contact with the mattress cover. Tests have surprisingly shown that thanks to this coating the sliding is considerably better, presumably because this makes the sliding blanket tighter, but the inventors do not want to be held to any theory. In certain embodiments, this is the only coating that the tow blanket 3 has. In other embodiments, a second coating may optionally be applied on the outside of the assembly, that is, on the side of the drag blanket 3 which normally comes into contact with the floor.
BE2017 / 5343
FIG. 6 shows the assembly 1 of FIG. 4, wherein the fixation straps 51, 52 are in their extended position, but wherein slit bodies 511, 512 of the first fixation strap 51, which together form a first snap connection, and slit bodies 521, 522 of the second fixation strap 52 forming a second snap connection, not yet clicked together. In practice, the fixation straps 51, 52 are preferably held in their stowed position during normal use of the mattress, such that a small part of it protrudes over a distance of, for example, 5 cm to 20 cm, e.g. about 10 cm, outside the assembly as shown, for example, in FIG. 4, and FIG. 8 to FIG. 12 and FIG. 20, and the fixation straps 51, 52 are only pulled out of their stowed position in the event of an emergency, to fix a person lying on the mattress cover 2.
FIG. 7 shows the assembly of FIG. 6, wherein the bodies 511, 512 of the first fixation belt 51 that together form a first click connection on the one hand, and the bodies 521, 522 of the second fixation belt 52 that together form a second click connection on the other hand are clicked together, and wherein the belts 51, 52 have been filed (although without a patient, for illustrative purposes).
In FIG. 4 to FIG. 7, assembly 1 is shown with the tow blanket 3 at the bottom and the mattress cover 2 at the top in the figure, which corresponds to a normal position of use of the assembly 1 on a bed, as suggested by the coordinate system Χ, Υ, Ζ with the Z axis pointing to points above. In FIG. 8 to FIG. 21 and FIG. 25 and FIG. 26, assembly 1 is shown with the drag blanket 3 on top and the mattress cover 2 at the bottom in the figure. In other words, in these figures, assembly 1 is shown upside down, as suggested by the coordinate system Χ, Υ, Ζ with the Z-axis pointing downwards. However, this position does not correspond to the normal position of use of assembly 1 on a hospital bed, but is useful for illustrative purposes, in order to better display certain parts. In FIG. 27 to FIG. 30, assembly 1 (or at least a part thereof) is again shown in the normal position of use.
FIG. 8 shows the assembly 1 of FIG. 4 upside down.
As already indicated above, the tow blanket 3 preferably has an octagonal shape, comprising a first zone 31 (in the middle) with a rectangular shape, and a second and third zone 32, 33 with a trapezoid shape. An advantage of an eight shape compared to a rectangular shape is that the draw loops 61, 62 are in line with the tow blanket, whereby stress concentrations can be avoided.
The assembly 1 comprises a first and second fixation belt 51, 52 which are in their retracted condition as shown in FIG. 8 are largely between the mattress cover 2 and the drag blanket 3, but the ends of the fixation straps 51, 52 protrude a short distance (e.g. 5 to 20 cm) from the outside
BE2017 / 5343 assembly 1, so that the fixation straps 51, 52 can be pulled out quickly, and the buckles being pulled out of their holder (e.g. elastic holder) in case of an emergency.
The assembly 1 preferably comprises means 514, 516 which will be further discussed in more detail in FIG. 21 to FIG. 24 to slightly hold or clamp the fixation straps so that they cannot or substantially cannot shift in the transverse direction during normal use of the mattress. This offers the advantage that the fixation straps 51, 52, for example, cannot fall to the ground, which can lead to problems with hygiene, or get entangled with parts of the bed (not shown) on which the assembly 1 is placed, which would save valuable time. are lost to release the fixation straps in an emergency situation. These means 514, 516 also allow the fastening straps 51, 52 to be pulled out quickly in an emergency situation without having to perform additional actions (such as first having to tilt the mattress to untie a knot or open a zipper or the like) . The means 514, 516 also ensure that the fixation straps 51, 52 also remain in place in the longitudinal direction, so that they do not get entangled with the pull loops 61, 62. These are very important advantages that contribute to the calm of the rescue workers and which contribute to an efficient evacuation, by ensuring that as little time as possible is lost to bring the fixation straps to their pulled-out state (to subsequently fix the patient), in situations where every second counts.
The assembly 1 comprises a first and second pull loop 61, 62 which are in their retracted condition as shown in FIG. 8 are largely between the mattress cover 2 and the drag blanket 3, but a part of the pull loop 61, 62, e.g. ends of the pull loops, project over a short distance (e.g. 5 to 20 cm) outside assembly 1, so that the pull loops 61, 62 can be pulled out quickly in an emergency.
The assembly 1 preferably comprises means 81 which will be further discussed in more detail in FIG. 16 to FIG. 19) to slightly hold or clamp the pull loops 61, 62 so that they cannot or substantially not shift in the longitudinal direction X during normal use of the mattress. This offers the advantage that the pull loops, for example, cannot fall to the ground leading to problems with hygiene, or become entangled with parts of the bed (not shown) on which the assembly 1 is being placed, which would result in the loss of valuable time for release the draw loops. These means 81 also allow the pull loops 61, 62 to be pulled out quickly in an emergency situation without having to perform additional operations (such as first having to tilt the mattress to untie a knot or open a zipper or the like). The assembly preferably also has means 614 which help prevent the pull loops 61, 62 from becoming entangled with the fixation straps 51, 52. These are very important advantages that contribute to the calm of the rescue workers and that contribute to an efficient evacuation by ensuring ensuring that as little time as possible is lost to bring the pull loops 61, 62 into their extended position (to subsequently be able to drag the assembly), in situations where every second counts.
BE2017 / 5343
FIG. 9 is another representation of the assembly of FIG. 8.
FIG. 10 shows the assembly of FIG. 9, the first pull loop 61 being largely but not yet fully extended. If there is a Velcro 81 at the location indicated in thick dotted line (but then between the mattress cover 2 and the drag blanket 3), this Velcro will automatically open when a strong pull is made on the first pull loop 61. If there is a indication at the location if there is no Velcro in thick dotted lines, the first pull loop 61 can simply be pulled out, virtually without resistance.
FIG. 11 shows the assembly of FIG. 10 wherein the first pull loop 61 is fully extended. The reinforcing edge 37 on the circumference of the tow blanket 3, which in continuous embodiments of the present invention is continuous and / or is integrally formed with the pull loops 61, 62, is also clearly visible. Preferably, the first pull loop 61 is formed in line with the to oblique, tapered segments 35a, 35b of the trapezoidal zone 32.
Optionally, the first pull loop 61 further comprises an intermediate piece 615 through which a third (shorter) pull loop is formed, at the same end (e.g. head end or foot end) as the first pull loop 61. It is of course also possible to have a separate third pull loop (not shown) to be provided with the same or different connection points 612, 613 as the first pull loop 61.
Similarly, the second pull loop 62 may include an intermediate piece for forming a fourth pull loop 64 (see FIG. 14) that is shorter than the second pull loop 62. Alternatively, the fourth pull loop may be a separate loop with the same or different connection points than those of the second pull loop 62. The third and fourth pull loop 63, 64 are optional, but if they are present they can be conveniently used when maneuvering through a door or other narrow passages, or when moving over a staircase.
FIG. 12 is another representation of the main end of the assembly of FIG. 11. Note that the flap 616 on which there is a Velcro strip 81b (see FIG. 13) is open.
FIG. 13 is an enlarged view of the circled portion of FIG. 12, wherein the head end flap 616 is folded up. In this embodiment, the flap 616 of the drag blanket 3 and the mattress cover 2 comprise connecting means 81a, 81b cooperating to form a Velcro 81. Velcro is known, and therefore does not need to be explained further. Suffice it to know that Velcro usually comprises two strips, mounted on different parts that need to be temporarily attached to one another, one strip usually comprising loops, and the other usually hooks, but other forms of Velcro are also possible.
BE2017 / 5343
In the example of FIG. 13, the first loop 61 is formed continuously with the peripheral edge 37, and formed from the same material, and the first pull loop 61 comprises an intermediate piece 615 for forming a third (shorter) loop 63
FIG. 14 to FIG. 17 show different steps for storing the first draw loop 61.
The storage of the second pull loop 62 can of course be done in the same way.
FIG. 14 and FIG. 15 shows a first step in which the pull loops 61, 62 are brought to the axis of symmetry LL (as indicated by the arrows A in FIG. 15), after which the Velcro 81 (more clearly visible in FIG. 13) can be partially pressed ( e.g. by exerting a force in the direction of the arrows B), except substantially in the middle between the connection points 612, 613.
FIG. 16 shows how the pull loops can then be introduced into the space between the mattress cover 2 and the tow blanket 3 by inserting them in at the center line L-L in the direction of the arrow C shown in FIG. 16, until the draw loop protrudes over assembly 1 over a desired length d1, e.g. in the range of 5 to 30 cm, e.g. about 10 cm or about 15 cm, or about 20 cm or about 25 cm.
FIG. 17 shows how the Velcro 81 can then be tightly pressed (e.g. by exerting a force in the direction of the arrows D), in order to slightly fix or clamp the position of the pull loop 61, and such that the pull loop is over a desired length dl protrudes outside the assembly. It will be apparent to those skilled in the art, after reading the present description, that the pull loop 61 can be simply pulled out of assembly 1 below (by pulling in the direction of the arrow E) in the event of an evacuation, and that the Velcro 81 will initially cause some resistance when the tensile force E is relatively small, but when the tensile force E is greater than a certain value, the Velcro 81 will open automatically, also when the assembly is oriented with the mattress cover 2 facing up and the drag blanket 3 down.
FIG. 18 shows an example of how the first pull loop 61, and if present also the third pull loop 63 (whether or not formed as a separate pull loop or with a transition piece 616) can be stored in the assembly 1 of FIG. 17, such that a portion of the pull loop 61 projects beyond the assembly 1 over a certain distance d1.
FIG. 18 shows that the assembly 1 can optionally comprise a storage bag 614, attached to the mattress cover 2 or as to the drag blanket 3, in which said major part of the pull loop 61 can be stored. As described above, the presence of such
BE2017 / 5343 storage bag 614 reduces the risk of the draw loops becoming entangled with the fixation straps 51, 52. Of course, the shape and position of the storage bag 614 is shown in FIG. 18 is only an example, and the person skilled in the art can, after reading the present description, simply devise other forms.
FIG. 19 shows a variant of the assembly 1 of FIG. 13 wherein the Velcro 81 is not essentially continuous between the two attachment points 612, 613, but is interrupted with a strip without Velcro, e.g. near the middle. Or to put it differently, wherein assembly 1 has two or more Velcro strips 81a, 81c which are in line with each other, with a certain distance d2 between them. It does not matter whether the Velcro 81b applied to the tow blanket is continuous or interrupted. Of course, it is also possible to turn around. In another embodiment (not shown), the velcro strap 81 comprises two strips which are extended in line with each other and at a distance d2 of, for example, 5 to 10 cm from each other, fixed to the slip blanket 3, and the mattress cover 2 comprises one continuous Velcro strip.
FIG. 20 and FIG. 21 and FIG. 25 and FIG. 26 show in more detail a preferred position of the first and second zipper 71, 72 for coupling the mattress cover 2 and the slip blanket 3, and the preferred position of the fixation straps 51, 52 relative to the zippers.
FIG. 20 is an enlarged view of a portion of FIG. 8. FIG. 20 shows a first zipper portion 711 rigidly connected to (e.g., sewn to) the mattress cover 2, and a second zipper portion 712 rigidly connected to (e.g., sewn to) the slip blanket 3, and shows how the first zipper portion 711 and the second zipper portion 712 together form a first zipper 71. On the other side of the assembly (not visible in FIG. 20) is a second zipper 72 with also two zipper sections. The first and second zippers 71, 72 are divisible zippers, which means that the mattress cover and the drag blanket can be completely separated from each other.
As shown in FIG. 5, the length d4 of the first and second zipper is shorter than or at most equal to the distance d5 between the two fixation straps 51, 52.
In preferred embodiments of the present invention, the ratio of the length d4 to the distance d5 is a number in the range of 70% to 100%, e.g., in the range of 70% to 98%, e.g., in the range of 80% to 98%, e.g., about 85% or about 90% or about 95%. It will be clear to a person skilled in the art after reading the present description that for a given distance d5 between the fixation straps, the greater this ratio, the stronger the releasable attachment between the mattress cover 2 and the slip blanket 3.
Preferably, the distance d4 is a distance of 50 cm to 100 cm, or of 60 cm to 100 cm, or of 70 cm to 100 cm, or of 80 cm to 100 cm, or from 90 cm to 100 cm.
BE2017 / 5343
In the same or another preferred embodiment, the ratio of the length d4 of the first and second zipper 71, 72 to the length d6 of the mattress cover 2 is a number in the range of 30% to 70%, e.g. 40% to 60 %.
In the example of FIG. 20 one end of the fixation strap 51 protrudes outside the assembly over a distance of about 5 cm to 15 cm, e.g. about 10 cm, which makes it possible to pull out the fixation strap 51 very quickly in an emergency situation, so that they lose little possible time is going. As will be further explained with FIG. 21 to FIG. 23, the length of the projecting portion is predetermined, in particular by the position of the elastic band 514 in which the split body 512 with a concave shape can be stored in the normal state of assembly. In this way (with correct use of the mattress) it is guaranteed that the protruding parts of the fixation belts are always virtually the same for each assembly. Although not explicitly shown, the same or similar elastic band or elastic is provided for the second end of the fixation straps 51, 52.
FIG. 21 (a) shows the first zipper 71 of the assembly 1 of FIG. 4, which first zipper 71 is formed by a first zipper portion 711 which is fixedly attached to the mattress cover 2 and a second zipper portion 712 which is fixedly attached to the drag blanket 3. The first zipper 71 extends in the longitudinal direction X of the mattress, over almost the entire distance between the fixation straps 51, 52.
FIG. 21 (a) also shows the seams 513 with which the fixation strap 52 is sewn or stitched or otherwise attached to the slip blanket 3, on the side of the slip blanket 3 that normally faces the mattress cover 2, such that the fixation straps 51, 52 are located between the mattress cover 2 and the drag blanket 3. In this way the risk that the fixation straps 51, 52 can get caught behind parts of the bed, or behind an object on the floor, during an evacuation, is almost completely excluded.
FIG. 21 (b) is an enlarged view of a portion of FIG 21 (a). It better illustrates how an end of the fixation belt 52, when it is in its stowed position, is slidably attached to the drag blanket 3, namely by means of an elastic band 514. In the event of an emergency, the rescue worker simply has to pull in the direction from the arrow F to the portion 516 that largely protrudes outside the assembly. When the force is large enough, the split body 522 will automatically release itself from the elastic band 514.
Although not explicitly shown, such or similar elastic connection is provided for all ends of both fixation straps 51, 52. The length over which the end 516 extends beyond the assembly 1 can thus simply be predetermined by a suitable length of the end 516 and a suitable length. position of the elastic band 514 relative to the reinforcement edge 37.
BE2017 / 5343
As can be understood from FIG. 6, the length over which the fixation straps can be pulled out is relatively short at one end (e.g. less than 30 cm), and at the other end relatively long (e.g. at least 120 cm). However, that is not essential for the invention, and the two ends could also be chosen substantially the same. It is, however, an advantage not to position the snap connection, in collapsed condition, in or near the center of assembly 1, because it would then be highly likely to be on top of a patient, which can give rise to discomfort or even injury. In preferred embodiments, when clicked together, the snap connection is positioned near the edge of the mattress cover 2, e.g., on a side wall of the mattress, as shown in FIG. 7, or at a distance of less than 20 cm from the edge. This position allows rescue workers to tighten the fixation straps 51, 52 faster and easier, with minimal discomfort to the patient.
FIG. 22 to FIG. 24 show in more detail how the fixation straps 51, 52 can be held in a stowed position by means of elastic strips or elastic bands 514, 516, and how they can be put back into the same elastic bands after use (e.g. after a fire drill) .
FIG. 22 shows the elastic band 514 which is fixedly connected to the tow blanket 3, but which can be opened for receiving the split body 512. This has, inter alia, the advantage that the distance over which the fixation straps project outwards can be accurately determined without this have to measure. Preferably, the split body has a concave shape with rounded corners, in order to offer a little more resistance to displacement thereof, so that it is better held in place by the elastic band 514, without, however, preventing it from being pulled out.
FIG. 23 shows a second elastic band 516 which is not located near one of the edges of the drag blanket 3, but substantially in the middle. This is suitable for receiving a part of the long end of the fixation belt. The elastic band 516 has the advantage that the fixation straps 51, 52 cannot get entangled with each other, nor can they get entangled with the pull loops 61, 62. It is noted that these problems cannot occur in the carrying mattress of FIG. 1 because these carrying loops are particularly short, and rather act as handles. FIG. 23 further shows how a central portion of the fixation strap 51 is fixedly attached (e.g., sewn or stitched) to the slip blanket 3. FIG. 23 also shows a second, more centrally located elastic band 516, for receiving the other (long) end of the fixation belt.
FIG. 24 is an enlarged view of a portion of FIG. 23.
BE2017 / 5343
FIG. 25 is a variant of FIG. 21, which shows that the same mounting principles can be used for both fixation straps 51, 52.
FIG. 26 shows the assembly of FIG. 25 after the first zipper 71 is half closed. As described above, it is not intended to partially close zipper 71, but only a transition state.
FIG. 27 shows that the mattress cover 2 itself can also have a zipper 27 with which the mattress cover 2 can be opened or closed for inserting or removing a mattress 4. It is generally known to provide a mattress cover 2 with a zipper. As stated above, the mattress cover 2 according to the present invention forms a complete covering around the mattress 4, and thus does not merely relate to a top side of the mattress cover 2 without a bottom side. The zipper 27 can be a watertight zipper, but that is not strictly necessary for the present invention.
FIG. 27 further shows that the mattress cover 2 can comprise a flap or border 28 which can be tilted over the zipper 27 of the mattress cover 2. This flap or edge 28 ensures that, for example, body fluids which end up on the mattress cover 2 will flow over the zipper 27, and the edge 28 thus reduces the risk that the mattress 4 contained in the mattress cover 2 will be damaged or contaminated . In FIG. 27, the edge at location A is folded up to make the own zipper 27 accessible, and the edge 28 is folded down at location B to shield the own zipper 27.
However, the presence of the board 28 is not mandatory, and the present invention will also work without this board. In such a case the zipper 27 will be visible, and the own zipper 27 is preferably a watertight zipper.
FIG. 28 shows the assembly 1 of FIG. 27, wherein the flap or collar 28 of the mattress cover 2 is folded or folded over its own zipper 27 (no longer visible in FIG. 28). The pull loop 61 protruding on the right-hand side of FIG. 27 and FIG. 28 does not form part of the mattress cover 2 itself, but does form part of the drag blanket 3 which is coupled at the bottom of the mattress cover 2.
FIG. 29 and FIG. 30 show the mattress cover 2 of FIG. 27 and FIG. 28 opened at one of the corners, and show an exemplary mattress 4 inserted into the mattress cover 2. In the example of FIG. 29 and FIG. 30 this is a foam mattress. It is important to note that in principle any type of mattress can be used, and that no recesses or inserts are required in the mattress 4, for example for receiving fixation belts or the like, whereby the choice of suitable mattress types is greatly increased. .
