    intervene any medical professional during the rescue process. This device
    may beas imism used-withidentical efficacy efficiency and effectiveness-how
    fifteen specific immobilizer device (DIE) in cases of pelvic fracture, fracture of
    Femur, knee fracture and tibia fracture near the knee.
    BACKGROUND AND CURRENT STATE OF THE TECHNIQUE
    The idea of creating this device arises from the need observed by a professional
    20 in their daily work as part of an extra-hospital medical emergency team, who warns that at present, rescue teams do not have a specific immobilizer device for femoral neck fractures that allow the evacuation of the injured patient with the injured member totally and properly immobilized,
    25 For descriptive purposes, in this document we will understand that the "rescue process- (understood as a whole, that is, since the emergency team arrives at the scene in response to a distress call until the patient is placed in front of the emergency traumatologist in the hospital setting) is composed of three phases: (i) a first phase of evacuation of the patient from the place where he lies until
    3D rescue vehicle, Oi) a second phase. constituted by pOI "the transfer of the patient in the corresponding rescue vehicle and (iii) a third phase, constituted by the hospital reception of the patient by in-hospital staff.
    Currently, the rescue professional arrives at the scene of the accident and performs a
    3S first evaluation of the injured subject to establish the extent of the injury / s. Nowadays. in cases where it is suspected that the patient has a fractured neck fracture injury, emergency professionals proceed to collect (without using any specific device) the injured subject from the ground with the "paddle table" and immobilize it with the support straps provided. The subject is
    40 evacuated without any specific immobilization and is only "properly immobilized" upon arrival in the emergency vehicle. when placed on a so-called "vacuum mattress" (a general immobilizer, designed for use with polytrauma patients) previously extended on the stretcher of the rescue or ambulance vehicle,
    45 The use of said "vacuum mattress" as an immobilizer in an event of such a specific and localized fracture presents the inconvenience of inconvenience. of overwhelming the patient during the time he is transported to the hospital, since it immobilizes the patient's entire body. not allowing mobility of any part of your body.
    SO also. the current lack of specific immobilization in cases of fracture of the neck of
    Femur sharpens the pain experienced by the injured subject during evacuation
    from the place where the rescue vehicle lies. Said immobilization fata
    specific in this first phase of the rescue (and the consequent sharpening of pain
    produced) makes the administration of medication (morphic rivados necessary).
    S pain heaters) to be able to make the pain experienced during said pain more bearable
    process. The use, today. of said immobilizing technique -employed exclusively
    during the journey of the transfer in the vehicle to the hospital ~ it is not only obligatory. how
    we said, that the evacuation from where the patient lies to the rescue vehicle
    It is carried out without any specific immobilization. It forces. Likewise,
    10 that upon arrival at the hospital the patient should be devoid of the immobilization that
    provided the "vacuum mattress" to be transferred to a hospital stretcher,
    seeing the patient, again, without any specific immobilization of the member
    injured during the first hospital stage. that is, reception, evaluation and
    realization of x-ray plates
    fifteen
    In town. patient evacuation from inside buildings to the ambulance is usually
    cover the added difficulty of having to lower the patient to the street from a floor. It
    it involves putting the patient in an inclined position (if he is taken down the stairs) or
    even vertical (if it is lowered by the elevator). Placing the patient in said position without
    twenty a specific immobilization (remember that general immobilization ~ the "mattress of
    empty "- it is not placed until it reaches the stretcher of the emergency vehicle) it produces
    a great pain that the patient has to endure and about how to evade.
    Precisely this specific immobilization fault causes that in these cases it is
    25 the intervention of a doctor is imperative; that is to say. in Spain. it becomes necessary to be
    move a complete advanced life support (SVA) equipment to the accident
    [composed in Spain of doctor, nurse and emergency medical technician asl for
    Meditate the injured patient to calm their pain. The medication is, in our
    country, an advanced life support technology, which are not authorized to perform both
    30 Health emergency technicians (TES) of a basic life support team (SVB).
    Therefore, today. in spite of the amount of time [transfers from the
    vacuum mattress] and resources rmedi co / medication] invested in the rescue of a subject
    injured with a fractured femoral neck. the pain is still very present during
    35 evacuation, since the patient is conscious and the medication (morphic derivative)
    which is administered by protocol, reduces. but it does not nullify a pain that worsens with the
    manipulation and movements of a rescue of this type. The above can be done
    Extensive to those cases in which the patient lies injured in a difficult place,
    complicated or impossible access for the rescue vehicle. tell yourself sea. field, mountain
    40 etc; or in those cases in which a doctor is not available or unable to reach
    time to the injured subject, being displaced to the personal place
    Non-medical rescue professional.
    Thus, the device that will be described below is profiled as a device.
    Four. Five Specific immobilizer (DIE) for cases of femoral neck fracture. injury to
    that today is not used by prehospital emergency personnel in Spain
    no specific immovable device (D IE).
    5 EXPLANATORY DISPLAY ILELPOSITIVE The design of the pennite device to rescue personnel will carry out rescue operations by minimizing the pain experienced by the injured person as a result of manipulation and evacuation movements. the transfer to the hospital center and the reception of the patient by hospital staff l.
    The specific immobilizer device has the following outstanding characteristics:
    10 Its anatomical form: the anatomical form with which the pennite specific immobilizer device has been designed to immobilize the patient efficiently. perfectly adapting to the anatomy of all kinds of people, as will be seen later.
    fifteen Central guide of telescopic structure: it allows aligning the affected lower limb when there is a fracture. adapting its length to the physical characteristics (leg length) of the injured subject. Allowing, therefore, the 'block' immobilization of the affected limb. completing a perfect immobilization of the affected member. from the pelvis to the ankle.
    20 2S Central guide with traction function: this allows the member to be returned to their original position and remain in that situation during the entire process of rescue, evacuation and transport of the patient to the hospital. The aim of the traction is to minimize the pain suffered by the patient due to the fracture (both of the femur or tibia proximal to the knee. And in some cases of the femoral neck fracture). to make possible the rescue of the patient without the need for medication. Traction will be carried out forward or backward depending on the type and characteristics of the subject's injury. preventing a worsening of the injury.
    30 3S 40 Materials used for the outer coating: (i) non-slip: the material that covers the guide is non-slip, also having small silicone ovals - or other material with similar characteristics or properties - strategically placed. to reinforce said function Thus, it prevents the painful sliding of the patient down when placed in an inclined or vertical position during evacuation; (ii) hygienic and easy to clean and maintain: the material that covers the exterior of the immobilizing device is easy and quick to clean. being able to be quickly put back into use after a previous intervention finished; waterproof: the material that covers the outside of the device is waterproof to be used in any condition and circumstance - especially regardless of adverse weather conditions; (iii) high strength: the material used is high strength. preventing its degeneration (tears, tears, etc.) by the abrasive contact with the surface on which the patient lies (home floor. ac ;; crado. stony ground. etc).
    Four. Five Viscoelastic material inside the padded interior of the device: the viscoelastic interior material dampens irregular movements during the movement and absorbs the vibrations produced during it. avoiding pain added to the patient and avoiding the need to use the vacuum mattress. It also favors (without compression on the injured area and the affected limb) the adaptability of the immobilizer device to the specific anatomy of the injured subject and with it perfect immobilization.
    fifty Radiolucent or radiolucent materials: the fact that the present immobilizer device is unsealed and made with materials translucent to
    X-rays make it easier for the injured patient to undergo such a session if n
    need to have the immobilizer (DIE) relieved. In other words. there will not be
    need to bother the patient until he is in front of the emergency traumatologist.
    5 Ease of use, versatility, flexibility, adaptability and versatility: The
    Specific immobilizer device that we present is very easy to use. coulding be
    used with identical solvency by all types of professionals and rescue personnel
    trained, experienced or not. Its low weight and compact design are all facilities
    for the professional who has to reach the place where the injured subject is.
    10 The present device can be used all kinds of professional rescue equipment (without
    there is no need for any doctor in it), being especially useful for units of
    Quick intervention that has different professionals working shifts
    consecutive. It can be adopted by any rescue team worldwide. is
    say, without any geographical limitation; the device lends itself to being easily
    lS produced and marketed adapted to the specific requirements of the different
    sanitary regulations worldwide and to the requirements of the different units of
    Rescue existing worldwide.
    The present device can. Likewise. be put into use in all types of fields: urban.
    twenty rural. of mountain and high mountain. in the maritime zone etc. and be used in all kinds of
    conditions (ranging from simple falls at home, in the call and to injuries in areas
    difficult access, natural catastrophe zone or connicto zones) and circumstances
    (indoor / outdoor, day or night. high or low temperatures or weather conditions
    Adverse etc). The device can be applied in a wide variety of situations in
    2S combination with other specific / general immobilization systems. can be
    used in all types of injured subjects regardless of age. complexion and measures.
    It has been designed to be used with the vast majority of the population (which
    according to recent statistical studies it presents a hip circumference of R l a
    127cm) The straps of the upper bands have a large size to provide
    30 maximum support for large patients. Pregnant women can be taken care of
    Use the device (DIE) without any danger to the fetus or mother.
    The advantages provided by the use of this device as described will be described
    continuation are at least;
    35
    1.-Maximum pain reduction: the use of this device allows to minimize the
    pain produced as a result of manipulation and movements of the
    Rescue process and transfer to the hospital of the injured subject. improving care and
    Patient's well-being The use of this specific immobilizer device (DIE)
    40 It has a fundamental advantage over the current way of evacuating. move and give
    reception to the injured person in the hospital. The present device allows the
    patient has the affected limb totally immobilized during the entire
    process, thus canceling the added pain suffered by it as a result of the
    handling. own movements, vibrations and displacements of the whole
    4S rescue process This advantage is especially important in those cases in which
    the patient cannot remain in a horizontal position once it has been attached to the
    "stretcher of shovels" in which he is evacuated; that is, those cases in which the staff
    rescuer is forced to tilt the stretcher and incorporate the patient to lower some
    stairs (gradual inclination) or use an elevator for evacuation (inclination
    fifty almost vertical maximum).
    2. · Speed and saving of time: the design and the characteristics of the device facilitate
    that the rescue is carried out with a single specific immobilization method that can
    be used throughout the pro (: that is, during evacuation to the vehicle of
    rescue. during the transfer to the hospital (without transfer to the vacuum mattress) and
    S during handling and movement (without transfers) in said center (included during
    the x-ray session) and that allows the period of time that elapses since it
    gives notice of the accident until the patient is placed in front of the traumatologist
    Emergency is drastically reduced.
    10 3. · Reduction of risk of worsening of the lesion: in addition to eliminating pain.
    the present immobilizer device avoids · by perfect and total immobilization
    of the affected limb (using its traction function. if necessary) · risks
    such as worsening of the injury; and even the possibility of an internal breakdown of
    vessels when rubbing with fractured bone during evacuation.
    fifteen
    4.-Saving of medical resources: first, the use of this device (DI E)
    causes the use of medication (morphic pain relieving derivatives), used today
    With the technique described. It is unnecessary. Secondly. device use
    immobilizer (DIE) makes it unnecessary to use the "vacuum mattress" to carry
    twenty carried out the transfer of the patient to the hospital. Third, its versatility. ·the fact
    of being able to perform a variety of functions simultaneously. that is to say. the fact of
    that the immobilizer (DIE) can also be used with identical efficiency. efficiency
    and effectiveness for the specific immobilization of other types of fractures (pelvic fracture,
    femur fracture. knee fracture and tibia fracture near the knee. as well as a
    25 variety of abdominal injuries) may result in emergency services not
    have to carry other devices such as "pelvic belt" in addition to DI E
    (for pelvic fractures and abdominal injuries) and / or "traction splint" (for fractures
    of femur and tibial fracture near the knee). The functions of these last two
    Devices can be made by the device (DIE) described here.
    the
    5. · Savings in human resources: as mentioned above, in Spain. the team
    of the units of "SVA, (Advanced Life Support) is composed of three
    professionals: a doctor, a nurse and a health emergency technician (TES) and the
    unit of a unit "SVS" (Basic Life Support) is formed by a couple of TES;
    3S that is, this last team is made up of only two professionals. of the
    which none is authorized to medicate the injured patient. So. the use of
    immobilizer device (DIE) allows the rescue of an injured subject in a
    alleged femoral neck fracture can be carried out by an "SVB" unit,
    making the intervention of a ·· SVA unit unnecessary ". that is, making unnecessary
    40 the intervention of a nurse and a doctor. The fact that the rescue process can
    be carried out by a team of · 'SVS ··. whose number is much higher in the park
    of ambulances in a city. allows the few "S VA" units available
    (as well as the 11m tado number of doctors and nurses that make up this local team)
    be released to deal with more serious accidents that urgently require
    Four. Five the intervention of "SVA" units, (ie. of medical staff and nurse).
    6.-High cost savings: the use of the described device presupposes, therefore.
    an important cost saving advantage, thus presenting not only impressive advantages
    regarding the quality of patient care. but important economic advantages-
    SW financial services for the company providing the ambulance and / or rescue service as well.
    Each of the above mentioned improvements and savings (say: (i) speed and
    consequent time savings on each service performed; (ii) savings caused by being
    unnecessary medication supplied with current technique and port redundancy
    different equipment to perform functions that the immobilizer (DI E) can complete
    S by itself; (iii) saving of human resources, which causes that the
    presence of a doctor to evacuate the patient and, therefore. the one that is not precise the
    presence of a complete team of "SVA") come to suppose the saving of the high cost
    added that causes the use of the current rescue technique.

Said description refers to one or more non-limiting examples of preferred embodiments of practical implementation of the immobilizer device (DIE). This invention is not limited by the modalities described or by the drawings presented,
    40 being able to practice in different ways, with different configurations, variations and varying dimensions. The terminology used in this description should not be construed as limiting, unless otherwise specified. It is also intended that section titles used herein are for convenience only and should not be construed as limiting the scope of the device.
    45 specific immobilizer (DIE) presented here.
    As we mentioned above, the immobilizer device (DIE) constitutes a newly developed specific immobilizer device that allows perfect immobilization 'in block' of the focus of the lesion and the lower limb affected in cases of fracture 50 of the femoral neck, constituting its main objective to enable effective rescue,
    efficient and effective - and especially painless - of the injured subject. all without need
    of administering medication to the patient and therefore. no need for
    medical professionals and / or nurses intervene during the rescue process. This
    Device can be used. likewise, with identical efficiency. efficiency and effectiveness
    S as a specific immobilizer device in cases of pelvic fracture, fracture of
    Femur, knee fracture and tibial fracture near the knee.
    The present specific immobilizer device (DIE) comprises the following
    elements. all of them shown roughly in figures 1.1 and figure 1.2 attached:
    10
    Central Guide (100)
    A central component that, as a backbone. fulfills the function of axis and
    support of the immobilizer device assembly, adopting the shape of a central guide
    rigid telescopic structure adjustable (100). This in turn presents the following
    1S Elcments:
    Central housing (200): Fixed rigid element
    This constitutes the first of the two segments that make up the aforementioned central guide of
    telescopic structure (100). The same (200) represents the main element of support
    twenty of the central guide (100) And of the device assembly.
    As can be seen in detail in Figure 4.1. the fixed rigid element of
    hollow tubular structure of the central guide (100). to which for descriptive purposes
    we call the 'center housing' (200) is made up of a hollow elongated tube of
    2S rectangular section and straight edge on its outer face (202) and reduced radius edge on its
    internal face (201). Said hollow tubular structure is made of high polyethylene.
    density (or other material with similar characteristics / properties). This case is
    sealed at its upper end (205) and open at its lower end (206). consisting of
    four faces and the opposite faces being "two to two" (figure 4.1). So
    3D we will distinguish two wide faces lcara (201) and face (202) 1 that they have. one face
    internal (201). that is in contact with the patient, and. the other. the outer face (202) that
    incorporates space so that (not directly on the housing. but on the material that
    it covers it in the way that will be described later) the device (D IE)
    screen printed on it the signal or signal chosen by the manufacturer for its
    3S identification at the time of marketing; and two narrow faces [face (203) and
    face (204)]. from which they extend. No continuity solution. at different heights
    of the central housing (200). the upper bands (600). the lower ones (800) and - where appropriate
    the middle bands (700).
    40 Coating: the entire immobilizer device (DIE). -that is to say. both the housing
    central (200) as the so-called upper bands or wings (600). lower (800) and. in
    Their case. stockings: (700), - it is covered by thin layers of polychloride
    vinyl (or other material with similar characteristics or properties). As stated in
    Figures 2.1 and 3. 1. a first layer covers the inner padded face (910) of the
    4S device set (DIE) - which will be in contact with the patient - and another covers the face
    non-padded exterior (911) of the device assembly (D IE). These two layers will remain
    fixed and secured to each other, by (il a series of vertical seams (912) -
    indicated in figure 3.1-that the bands of the device run equidistant
    longitudinal and (i) by a flange (913) consisting of a thin band of material
    fifty polyester textile (or other material with similar characteristics or properties) that is sewn with
    A seam (914) runs both the perimeter of the bands (600). the bands (800) and. in its
    case. the bands (700), such as the perimeter of the housing fixing both layers -light (9 10)
    And external (911) -And reinforcing the entire outer edge of the device (DIE) (figures 2.1 and
    Figures 3.1). Fixed on the cover of the outer face of the housing (202) is
    5 they find some ovals of if licona (207) that allow to complete the immobilization of the
    subject acc ideed by fixing it to the spinal board on which it rests
    "already immobilized" by means of the immobilizer device (figure 4.3). These oval are
    have been integrated into the housing and are adhered (with industrial contact adhesive) to
    its structure (200). The external face of them is in direct contact with the table
    10 spinal increasing the adhesion of the outside of the device assembly
    immobilizer enhancing the adhesion of the material that covers it, thus avoiding that
    the patient slips on said board during the evacuation, even in cases in which
    that it must be evacuated in an inclined or completely vertical position.
    fifteen Inside the central housing (200): it houses the second segment (300) of the
    telescopic structure of the central guide (100) that when extended. -using the mechanism
    of gears (500) that can be seen in detail in figures 6.1 and 6.2), allows
    the central guide (100) can adjust its total length to the anatomy of the injured subject.
    extending said segment (300) in a controlled manner along the affected member
    twenty (figures 1.1. 1.2 and 4.2) until the "lobillcra band" fixed at its distal end (400) is aligned
    with the ankle of the injured subject.
    Lane is: The two solid guides of rectangular section (301) and (302) commented. that
    they make up the structure of said extendable segment (300) of the central guide
    25 Telescopic (100) are permanently held in position and aligned in a row:
    lanes in fonna of "U" (208) that run the entire length of the inner side of the
    lower faces (203) and (204) of the housing (see figures 4.1, 4.2 and 6.2) And that are
    integrated into the housing body (200) allowing total stability. The same
    (208) present at its distal end a tab-shaped stop (209) that helps
    30 the guides are kept inside the rails at all times (see figure 6.2) and that the
    they cannot accidentally hit the mechanism (500) housed inside and
    that cannot cause the telescopic element (300) to be completely removed from
    the housing in which there is fastening (200). That is, the guides slide along these
    lane is (208). avoiding any moment of movement or movement (both horizontal
    35 as vertical) during its extension and retraction. avoiding potential deformations of
    the tubular structure of the mobile or telescopic element (300) and "clearances" that could
    cause said structure not to fit in the mode due to the anatomy of the subject
    hilly.
    40 Die: The lower half of the outer face (202) of the housing (200) has a lroquel
    (210) that enables the connection of the gear system (500) housed in the in te ri or with
    a lever or crank on an external wheel shaft (501) through which the
    the aforementioned mechanism (500) manually (see figure 6.2).
    4S Cover: As mentioned above. the upper side (205) of the housing (200) has been
    blinded confonting a closed structure with the same physical characteristics as the
    rest of the housing structure (200). The lower end (206) of said housing (200),
    Conversely. It was initially open. This one, however. will be presented sealed by
    a cover (2 11) see figure 4. 1] which has only two holes -reformed by
    SW two metal washers (or other material with similar characteristics / properties)
    Rectangular (2 12) [see figure 4.1] that avoid rubbing and wear-of the exact dimensions of the perimeter of the two guides (301) AND (302) that constitute the structure of the extensible telescopic element (300) of the guide (100) . Dc this mode. the inside of the housing (200) -and its mechanism (500) -of dirt is protected and insulated. items that can clog
    5 its operation. etc .. while reinforcing the clamping function performed by the "U" rails (208) described above and allowing an aligned extension and withdrawal of the same during the entire useful life of the device (DIE) [ figure 4.1].
    Therefore. the central housing (200), as a fixed element of the central guide
    10 (100), allows the performance of the following functions: (i) an axis and support function, as a backbone. of the device assembly (DIE). a housing function housing the extensible or telescopic element. as well as the mechanism that regulates it. allowing it to be accessed through its structure for operation from outside; (ii) a support and stabilization function for the affected lower limb.
    15 find the injured subject in a vertical situation. horizontal or inclined: (jii) an alignment function of the affected lower limb; (iv) a slip prevention function of the patient's body when it is in an inclined or vertical position on the spinal board during the evacuation: (v) and, finally. be the key piece so that the integral function of the device is possible, which is to provide a
    20 perfect specific immobilization that allows a maximum reduction of pain during the manipulation and movement of the patient in a prehospital rescue operation (composed of the three phases mentioned: evacuation, transport and reception) without the need for the presence of medical and nurse personnel. and without administration of medication to calm the pain.
    25 Telescopic segment (300): rail element: extendable As we discussed above, and as can be seen in figures l. l AND 1.2. the central guide
    (100) has a telescopic structure with two longitudinally successive sections or components that work: (i) as the main support element and with a housing (200), the first and (ii) as an extensible mobile element (300), the second, so that the length of the central guide (100) can be adapted to the anatomy of each patient. leaving the band "ankle" (400) -which has been attached to the distal end of the central guide (100) -always positioned (during use) at the ankle of the injured subject. The extensible segment (300) of the telescopic central guide (100) is composed (see figures 2.1.3.1 and 4.2) by a structure formed by two rigid tubular guides illustrated as (30 1) Y (302) respectively], located parallel to each other forming a symmetrical set. These guides slide in unison. As a single unit. on the U-shaped rails (208) commented. When they exit the housing (200) _ they extend in the opposite direction to it. staying aligned in
    40 at all times with the central housing (200) and enabling. therefore, that the mentioned first (200) and second (300) segments form a rigid and stable functional whole: the so-called central telescopic guide (100) See figures 1.1 and 1.21.
    These guides (30 1) and (302) have a solid tubular structure of rectangular section
    45 may be made of aluminum (or other material with similar characteristics / properties). Further. both guides are maintained as an equidistant rigid assembly, by two welded tubular elements (preferably) perpendicularly (to them) at both ends of the segment [upper section (304) and lower section (305)] forming a rectangular tubular structure of closed perimeter
    50 (300). The four sections commented. the two long and the two short ones are equal to their
    opposite "two to two" and present (preferably) identical tube section. Both
    Short sections are not visible to the eye of the observer. since the upper end of the
    Extensible segment of the guide (300) always remains inside the housing (200).
    making sure that this is the case in the state of Fonta de Pestat'ia mentioned above (209); Y
    S the bottom extrm remains embedded in which. for descriptive purposes, we call
    "ankle band" (400). giving the sensation to the observer that unicamentc is composed of
    a double independent tubular guide. Oicha structure is thus tremendously robust and
    compact being resistant to deformations that could be caused by use
    abrupt and inexperienced immobilizer device (D IE).
    10
    As we have mentioned, at its lower distal end (305), the extensible segment (300)
    of the telescopic central guide (100) provides support for the so-called "ankle band"
    (400) forming a "T" shaped structure (clearly visible in the figures
    2.1, 3.1. 5.1 AND 5.2). Said distal end (305) of the extensible segment (300) that we
    lS occupies is embedded in a small hollow rectangular housing (401) made of polyethylene
    High density (or other material with similar characteristics / properties) contained
    housed inside the "ankle band" (400) (see figures 5.1 and 5.2].
    It only has space inside to fit just that distal end
    (305). The opening inside the housing will be completely blinded
    twenty by the same tubular structure described (305) forming a solid block. The extreme
    distal (305) of the extensible segment (300) will be fixed with a polyurethane adhesive
    Reinforced with fiberglass (or a similar alternative adhesive substance) Figure 5.31
    The housing (401) is fully covered by a layer of vinyl dye polyeloride (or
    2S other material with similar characteristics / properties) and has two washers
    rectangular mctalicas (or other material of characteristics / similar properties).
    accommodating around the perimeter of both guides (JO 1) Y (302). fulfilling the
    function of protecting the coating material from possible friction and wear due to the
    intensive use of the central guide (100).
    30
    The extensible element (300) of the central guide (100) allows the achievement of the
    following functions: (i) the alignment function of the affected member in cases of
    femoral neck fracture; (ii) the function of enabling traction of the affected limb
    by using the millimeter gear mechanism provided for use in case
    3S dc fracture of the femur or tibia proximal to the knee; (iii) the reduction function of
    bruising and worsening of the lesion or fracture in the previous cases: (iv) the
    pain reduction function by repositioning the bone in the affected limb; Y. throughout
    case. (v) the specific immobilization function of the affected member and both
    lower limbs in block.
    40
    "Ankle brace" bottom (400)
    This band (400) that for descriptive purposes we will call "ankle band", (to comply
    the function of fixing the central guide (100), securing its lower end (102) to the ankle
    of the sujc: to attack) is attached to the far end (305) of the rigid component
    4S extensible (300) of the central guide (100) arranged perpendicular to the axis (103) of
    the telescopic central guide (100), forming a foona structure of "r" (Figures 2.1, 3. 1, 5.1 and 5.2).
    The housing (401) made of polyethylene of high density (or other material of characteristics or
    fifty similar properties) housed inside it constitutes the basis on which it is located
    adhered (with industrial contact adhesive) a major central trapezoidal element
    (402) high density polyester foam (or other characteristic material or
    similar properties) (figure 5.3). As can be seen in Figure 5.3. to both
    sides of said major trapezoid (402) are arranged in parallel two symmetrical bands
    S [illustrated as padded band (403) and padded band (404)] each with a series
    of five trapezoids of smaller dimensions (and identical material) attached (with adhesive
    industrial contact) on a basis of high density polyethylene (or other material of
    earactcristicas or similar properties) that reacts to the endoskeleton function (at the same time
    what happens in the other bands (upper) (600) and middle (700) and lower (800) of the
    10 DIE immobilizer device, as described below). The structures
    Trapezoidal mentioned confront the "padded" (910) or internal face of the "band
    ankle brace "(see figure 3.1 and figures 5.2 and 5.3), fulfilling the function of hugging the ankle
    of the affected member. adapting perfectly to the anatomy of the injured subject
    (uncompressed) and, therefore, fulfilling the objective of allowing a perfect
    fifteen immobilization. It should be noted that the upper face of the major central trapezium (402),
    on which rests the ankle of the injured subject, has a curved anatomical shape
    to facilitate a perfect fit to the member and, consequently. a perfection
    in mobilization.
    twenty The set is covered by two sheets (one inside. In contact with the patient
    and covering the padded face (405) (see figures 3. 1 and 5.2) and another exterior (406) (see
    Figures 2. 1 and 5.1) of vini lo polychloride (or other material of characteristics or properties
    yes millers) sewn to each other. (i) using a double perimelral seam (407) -and without
    present, [unlike what happens with the perimeter of the rest of the device (DIE)]

    reinforcement of the edges of the band ·· tobi ll era '· (400) -y (ii) by seams (408)
    arranged in a longitudinal way that separate and fix each one of them in parallel
    trapezoidal elements (402. 403 Y404) described above (see figures 5.1 and 5.2).
    As can be seen in figures 5.2 and 5.3. internal padded side of the set
    30 described (405), and specifically. on the upper face of each of the elements
    previously described trapezoidal [on the coating (405) of polychloride of
    v inyl (or other material of similar characteristics or properties)] are found ad he rides
    (industrial contact adhesive) a series of "semi-circular non-slip spheres"
    (409) and (4 10). These are arranged, without limiting effects and for the effects that we
    35 affect. in a line of three in each of the ten minor elements (409) and in two lines
    of three (six in total) in the central trapezoidal element (410).
    Two short straps: sewn-seams (4 15) of nylon thread (or other material of
    characteristics or similar properties) - on the outer face (406) of the layer of
    40 coating, there are two straps (411) and (412) that extend perpendicular
    to the axis (103) of the moving device (DIE) in the same direction of the bands (403)
    and (404). These straps will be made of nylon and polycster twill (or other
    material with similar characteristics or properties) and will incorporate a closure system and
    quick contact opening type VELCRO® (414). -Fixed straps by seams
    Four. Five perimetral (416) of nylon thread (or other material of characteristics or properties
    similar) -which surround the tobi llo of the affected leg and complete and make possible the
    clamping of the ankle bands (403) and (404) described (see figures 5. 1 and 5.2).
    Long belt: additionally, and as seen in figures 5. 1, 5.2 and 5.3, the "band
    fifty ankle brace "(400) has a third strap (413), - considerably longer than
    the two (411) and (412) described above-, sewn (415) with thread or nylon (or other
    material with similar characteristics or properties) on one of the small ones (411). The
    it has the function of completing the immobilizing function of the band as a whole
    "ankle brace" (400) surrounding and jointly fixing the two legs of the subject
    5 hilly. in order for its members to be fully aligned and form a
    Compact and stable "block". This long strap (413) also incorporates a system of
    YELCRO® (414) type quick contact closure and opening that is fixed to the belt
    by a perimeter seam (416) of nylon thread (or other characteristic material
    or similar properties).
    10
    Yelcro® type closures: both short straps (411) and (412) have the FEMALE side (or
    soft) of the closure (designated with the letter H in the corresponding figure 5.2) on its face
    internal and the MALE side of the closure (designated with the letter M in the corresponding figure
    5.1) is located on the outer side of the wings. so that when
    lS approximate for anchoring, the HEM BRA side is always superimposed (of any
    of the two straps) on the MALE side (of either one) that remains fixed.
    The same principle vllle pllmla long strap (413) (which only exists on one of the two sides

    Padded band: finally. we mention a small padded band (417)
    on which the patient's foot rests and whose purpose is to avoid chafing. The
    same will be stitched - seam (418) of nylon thread (or other feature material or
    2S similar properties)] along the lower edge of the band ·· anklet "(400), eslan3

    (or other material of similar characteristics or properties) used for coating
    of the rest of the immobilizer device (DIE).
    30
    This element ("ankle band") allows the performance of the following functions: (i)
    perfect attachment of the device (DIE) to the ankle of the injured subject (which depending
    of its particular anatomy it will be placed at a different height); (ii) enables the perfect
    alignment and immobilization "in block" of both members in conjunction with the
    35 telescopic element (300) of the guide (lOO) and, therefore, a safe and painless evacuation_
    Drive mechanism (500)
    The central guide (100) of the DIE -which it presents. as said, a tdescopic structure of
    two segments (200) and (300) - it has the characteristic of being adjustable by means of a
    40 inner mechanism (500). As can be seen in Figures 6.1 and 6.2. the housing
    Central (200) houses a simple straight gear mechanism inside
    (500), consisting of a set of two wheels or parallel axle gears: (i) a
    major gear (502) that functions as 'crown' or drive gear. and that
    it constitutes the one on which the impulse or force is exerted manually from outside
    Four. Five of the device (DIE) -through a "crank" or "wheel" (501) with which it is found
    connected-and (ji) another minor gear (503) that functions as "solidarity piMn"
    compared to the previous one. Both are located horizontally, being. of a
    part, meshed with each other and, on the other. in turn engaged in the "indentations" of the
    internal faces (301 a) and (302a) of the respective guides (301) and (302) (see figure 6.1). He
    fifty set, tell yourself the two gears. major (502) and minor (503), the two axis sections
    of the major gear - illustrated as shafts (504a) and (504b) - and the minor gear shaft
    (505) are designed to be made of aluminum (or other material with similar characteristics or properties).
    5 The upper section of the major gear shaft or crown (504a) is fixed to the "" crank "in the form of a '' wheel '(501). The latter is made of high density polyethylene (or other characteristic material or similar properties) and enables the manual operation of the internal gear mechanism It is noted that said "crank" is coated with rough non-slip material (or other material of characteristics or
    10 similar properties) to facilitate its grip in all types of conditions. When said upper section of the major gear shaft or crown is manually operated (by pulling it out) the lower end of the shaft (506) exits the groove.
    (510) arranged at the point at the center point of the "major gear" or "crown". When said crank (501) is stopped, said lower end of the shaft (506) returns to rest within said groove (510). The lower section of the major gear shaft (507a) and the lower part (507b) of the minor gear shaft remain in place thanks to the grooves (SIDa) and (510b) with raised flange (see figure 6.2) present on the face internal base (201) of the central housing (200). A spring (512) is placed on the larger gear, which allows the mechanism to be activated to give rise to
    20 securing and releasing the mobile or extendable segment of the guide (JOO). Said dock
    (512) is fixed at its two ends. the upper one (in contact with the "" crank "or" wheel "(501) 1 and the lower one (on the surface of the main gear. wrapping the upper Iramo of the gear shaft (504a). When said spring is at rest (it is that is, when the lever or crank (50 1) outside the housing (200) is not operated, the mechanism works by helping to ensure that the guides (30 I) and (302) remain in place and do not move. When it is on the contrary, in an elongated state - that is, when it is elongated as a result of the manual operation of the lever (50 I) -, the mechanism works by releasing the upper section of the shaft (504a) from the slit. of the larger gear (510), allowing both gears (larger (502) and
    30 minor [503]) can rotate on their axes [(S04b) and (505)] _ The guides [(301) and (302)] can thus be extended as necessary in a single movement. by pulling them the professional rescuer manually. removing them from the cenlral casing (200) in which they are at rest.
    35 It should be pointed out that although the millimeter "bites" that mark almost all of the inner face of both guides (30 I a) and (J02a) are the same (in the sense that they have the same dimensions). These are not placed symmetrically, facing each other. That is to say. to allow both guides [(JOI) and (302) 1 to be extended or retracted in unison. they are "synchronized", if you want to express it like this. in a
    40 asymmetric position. the one respect to the other. Be warned. Likewise. that the "bites" represented in Figure 6. l have been increased for descriptive purposes. not coinciding -ex professed- with the dimensions of the teeth of the gears that must be inserted into them.
    45 Thus, by means of the manual operation described - (pull the lever or crank (50 1)) the internal mechanism of the immobilizer device (DIE) fulfills a triple function: (i) on the one hand it keeps the telescopic segment extensible (300 ) of the guide (100) attached when it is folded or at rest inside the housing (200); (ii) by another, it allows extending the telescopic or extendable segment (300) of the guide (100) - aligning the 50 affected limb - remaining fixed in place once the "band" has been placed
    ankle brace "(400) at the level of the ankle of the injured subject; (jii) finally. the mechanism
    of millimeter gears (500) described SI / pra, is designed to allow
    Assumptions of femur fracture and tibia fracture near the knee. by turning
    the telescopic segment (300) of the guide (100) can be extended from the wheel
    S "millimeter to millimeter", allowing traction, in a delicate and precise way. of the
    affected lower limb,
    Top (600), middle (700) and lower (800) frogs or wings
    Again, exclusively for mere descriptive purposes and without having a character
    10 limiting, we will call these elements of the immobilizer device (DIE): "bands" or
    "wings." As shown in particular in Figures 2.1 and 3.1, the guide or central housing
    (200) presents a total of six sections conceived or attached to both sides of it.
    They start from both sides of the central guide segment (100) that
    we call "central housing" (200) and extend perpendicular line in the direction
    fifteen opposite the vertical axis (103) thereof (100). The above bands or wings
    provide the device (D IE) with both vertical stiffness and horizontal flexibility,
    thanks to the unique equidistant longitudinal arrangement of a series of sheets that
    together they constitute a kind of semi-rigid "endoskeleton" (900),
    shown in Figure 9.1, Three are the types of bands that are typically presented: (i)
    twenty Set of two upper bands (600) ~ to be placed at the height of the pelvic area
    of the patient- (figures 7.1. and 7.2) arranged symmetrically on both sides of the guide
    [band (601) and band (602)], presenting a "non-padded" face (604) OR outer face and
    a "padded" face (603), which forms the inner face that will be in contact with the body
    of the injured subject. As can be seen specifically in Figures 7.1
    2S and 7.2, the bands extend their function in the form of belts [belt (605) and belt (606) 1
    that fit around the injured subject; (ii) Two-band (optional) set
    stockings (700) - to be placed. where appropriate, at the height of the patient's femur area
    (Figures 8.1. and 8.2) arranged symmetrically on both sides of the guide [band (701) and
    band (702) J, also presenting a "padded" face (703). that makes up the face
    30 internal bands. and that in contact with the body of the injured subject and a
    "non-padded" face (704) or outer face. As can be seen specifically
    in figures 8.1 and 8.2. the bands extend their function in the form of belts [strap (70S)
    And belt (706) 1 that fit around the injured subject; (iii) Set of two
    lower bands (800) -which will be placed at the level of the patient's tibial area- (figures
    35 8.1. AND 8.2) arranged symmetrically on both sides of the guide [band (801) and band
    (802)], presenting, like the other bands, a padded inner face (803) and a face
    external '; not padded "(804), as can be seen specifically in the
    Figures 8, l and 8.2, the bands extend their function in the form of belts (belt (805) and
    belt (806) 1 that fit around the body of the injured subject,
    40
    "Endoskeleton" of die cut sheets (900)
    Each one of the sections or lateral bands that extend to each side of the guide (60 1)
    Y (602), (701) Y (702), as well as (801) and 1802) have an endoskeleton (900)
    formed by a series of independent rigid sheets (90 1) that run in
    Four. Five parallel to the central housing (200) the entire interior of the device in the direction
    longitudinally and continuously (see figures 9.1, 9.2 and 9.3). These sheets are
    arranged in parallel equidistant (to allow space in which
    the longitudinal seams (912) that fix the inner layers (910) and the
    external (911) covering the immobilizer device, as already described
    fifty supra), presenting a straight or rectangular tubular structure with two minor sides
    (902) Y (903) that make up the thickness or thickness of the sheet and two sides greater than
    They present the particularity of being. a flat one on its "internal" face (904) [face on which
    the viscoelastic material (906) will be fixed and if it is curved in its "external" face (905) [see
    figure 9.3]. This allows the aforementioned longitudinal seams (912)
    S are protected from chafing with the soil [or any surface on which the
    injured subject], when the device must be slid under the subject's body
    damaged during use [also detail in figure 4. ].
    This kind of longitudinal internal "infrastructure" is constituted by the mines (901)
    10 of high density rigid polyethylene (or other material with characteristics or properties
    similar) punched (907) (figure 9.1) that have different lengths depending on
    section (600), (700) where applicable. (800) or (400) in which they are placed. These
    Blades slow down. in any case. before reaching the edge of the device (D IE) to
    allow both layers (internal (910) and external (911)] to be joined and sewn along
    fifteen of the perimeter. forming the flange (913) described above (see figures 2.1 and 3.1).
    The above dies (907) have a variable configuration. matching your
    central point with imaginary longitudinal axis (908) that runs through each of the plates
    in question (901) (see figure 9.1). Its mission is to lighten the weight of the whole,
    twenty making it more manageable and making use of the least amount of material possible;
    this, of course, without compromising the characteristics of said material and its purpose.
    Each of the sheets (901) has adhered (with industrial adhesive)
    [represented in Figure 9.3 as (904a)] to its surface of its upper or inner face
    25 (904) a 'rectangular' longitudinal layer of viscoelastic material (906) covering the
    all of its surface. The set of said sheets and viscoelastic material
    confront the inner or padded face (910) that is in contact with the body of the subject
    rugged and that allows the device to adapt (uncompressed) perfectly
    to the unique anatomy of each patient (see figures 3.1. 9.2 AND 9.3).
    30
    Function: The described endoskeleton (900) allows to simultaneously combine the
    functions of (i) giving vertical rigidity to the set. extending the stabilization function
    and patient alignment mainly carried out by the central guide (100) Y (ii)
    to accentuate the function of flexibility and horizontal anatomical adaptation of the bands
    35 or wings of the immobilizer device (DI E) (or if parallel metric sections) to the body of the
    patient. The combination of both previous functions is what allows. definitely. the
    handling. evacuation and transfer of the patient without pain. no medications and no
    intervention of a professional in the prehospital stage of the care of the
    patient.
    40
    Re-estimate or cover the device (910) and (911): As can be done
    mainly appreciate in figures 2.1 and 3.1. the immobilizer device (DIE) is

    PROCEDURE FOR USE OF THE DIE
    The basic phases of a procedure for using the
    present device. which includes the following stages:
    twenty -The emergency team (composed in Spain - as a rule - by two or three
    professionals) or rescue approaches to the place where the subject is injured.
    Be this a public road, a property. A rural area etc.
    -The emergency or rescue team carries out a quick assessment of the subject
    injured to establish the extent of the injury (s). In case the subject
    2S rugged present signs and symptoms that suggest a fractured neck injury
    femur, the emergency professional (paramedic, doctor, nurse or technician in
    health emergencies) or rescue will proceed to make use of this new device
    Immobilizer (DIE) as detailed below.
    -The immobilizer device in question (D IE) will be placed open or extended -
    30 resting on its external or non-padded face * · on a spinal board, being
    presented in parallel to the injured subject at the height of his hip,
    -One of the healthcare professionals or rescuers will slide the immobilizer device
    (DIE) under the injured subject while his partner holds the patient in position
    lateral decubitus, with the affected limb held in position.
    3S -So. while one of the professionals places and maintains a lateral decubitus position at
    patient and the other holds the affected lower limb. both will proceed so
    set and simultaneously slide the spinal board with your free hand - along with the
    immobilizing device on the same-under the patient at the appropriate height (i.e.
    they will do it depending on the height at which the focus of the injury or fracture is found).
    40 -Once the patient is returned to the supine position. the professional makes sure
    that it is located on the immobilizer device (DIE) properly.
    -In order to ensure an adequate venous return. the rescuers will proceed to
    aj use the fastening straps in ascending direction. adjusting the straps first
    de ;: the lower bands or wings (at the level of the tibia), secondly the straps of the
    4S middle bands or wings (at the level of the femur) - if they existed in the configuration of the
    concrete immobilizer (DIE) - and finally the straps of the upper bands (level
    of the hip and / or pelvis).
    -In the exceptional case that the anatomy of the injured subject so requires, the
    Emergency personnel or rescuer will place during the previous procedure the
    SW provided pads that you think are necessary to fill in the anatomical gaps left
    Application No. F.Ercctiva F.OEPM
    P20 1 500885 2511112015 10/1212015
    by the particular anatomy of the injured subject, thereby guaranteeing a perfect
    patient immobilization.
    -Once immobilized the patient at the height marked. proceed to placement and adjustment
    of the telescopic or mobile section of the guide at the patient's ankle. The guide will
    5 It will extend depending on the length of the affected limb of the patient. so that the "band
    ankle brace "and its straps align in parallel with the ankle (or ankles) of the subject
    hilly.
    -The next step is to adjust the ankle straps of the affected limb.
    -Traction: In case of hip fractures. Femur and tibia next to the knee. we proceed
    10 to be pulled (in descending or ascending direction. depending on the case) the member
    lower affected with the guide to align the fracture. minimizing pain and
    make up for the lack of medication. In case of fracture of the pelvis or knee it would not be
    necessary.
    -Distal pulse: Once the limb is pulled, we proceed to take the distal pulse.
    fifteen to observe that there is blood supply and with it oxygenation of the distal tissues.
    -For the patient to form "a block" facilitating evacuation. we proceed to adjust
    the second of the belts available in the "tobi [lera" band). The same
    It is long enough to hug both limbs. the one affected by the injury and
    the unaffected, forming a "block" that stabilizes and immobilizes them "in block"
    twenty absolutely, minimizing movements. vibrations and. therefore. the pain.
    -Finally the patient is attached to the spinal board on which he rests already immobilized
    using the fastening straps provided and proceeds to evacuation until
    vehicle used in the corresponding rescue service or operation.
    -In contrast to the current technique exposed above. the use of the immobilizer (DIE) allows
    25 that the patient be transferred directly to the hospital. without having to be transferred to
    vacuum mattress that is to say. the use of the immobilizer (DIE) allows the patient to be
    transferred to the hospital making use of the same resources (spinal board and
    immobilizer (DIE)] with which it has been evacuated.
    -E [type of material used in the design and preparation of the immobilizer device (DIE)
    30 it allows that when arriving at the hospital the patient can undergo X-rays without the need for
    remove the immobilization (under normal circumstances - that is, using [a technique
    current-should have passed the patient from the vacuum mattress to a stretcher or bed).
    . The patient is finally transferred from the X-ray department to be treated.
    by the emergency traumatologist. without the withdrawal of the
    3S immobilizer (DIE) -placed to [atient at e [time of evacuation-and without
    repeated patient transfer was necessary. This results in an unbeatable
    quality of patient care during the entire process, that is, its handling and
    movement at the scene of the accident. his evacuation and transfer, his reception and his first
    hospital care.
