    Modular respiratory mask consisting of several components: a buccal shell (1), a curved tubular piece (5), a pad (2), nasal olives (3), a Y-shaped tubular structure (4), and a device belt (6). The innovative aspect of the invention is the possible combination of large oral carcasses with small nasal olives, and vice versa, in order to be used by a greater number of users, as well as being able to exchange the different pieces, so that you can have a breath Oronasal, nasal and oral without the need to acquire different masks and thus facilitate the dynamic interface and a better adaptation of the patient. Being small modules, a lower visual impact is achieved. Likewise, as the frames of transparent material are manufactured and allow for their size and shape the conversation, the barrier between the patient and society is diminished.

    [0003]
    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] Within the medical / health sector there are different types and models of respiratory masks for non-invasive mechanical ventilation that support patients with any respiratory deficiency. Thanks to these respirators and their accessories you can increase the hope and quality of life of the user.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The main problem that this type of ventilation presents is the bad adjustment of the mask to the face, producing leaks and therefore, decreasing the effectiveness of the respirator, or creating facial ulcers by pressure, preventing the continuation of the treatment, seriously damaging the health of the user.
    [0011]
    [0012] Most masks have the same parts, a pad that is in contact with the face, an external shell that is the one that provides consistency, and a strap that keeps the mask in position.
    [0013] There are different types of masks depending on the needs of the patient: oronasal, nasal, oral or full face mask. Of these four types, the most complete is the oronasal one, but the problem of the latter is that when it covers the entire face it is more difficult to achieve a total seal, in addition to the discomfort of having the same pressure always in the same areas, Therefore, it would be advisable to have several masks to be able to exchange them so that the face can rest, playing with the so-called dynamic interface.
    [0014]
    [0015] To meet this need of the dynamic interface and obtain a better result of the adjustment, this invention arises that allows to obtain three types of mask in one.
    [0016]
    [0017] US 00829.7283 B2, ES-0096844_U and US 00829.7283 B2 have oronasal masks that surround the mouth and nose, allowing breathing by both means and usually have the same properties: in some cases they have a Padded pad that is in contact with the patient's face, as shown in documents ES-0295621_U and ES-1001565_U, and in other cases a pad made of an elastomeric material, as is the case of ES-2656019_T3.
    [0018]
    [0019] In documents such as ES-2572167_T3, nasobuccal models are presented in which masks adaptable to the user's facial dimensions are described.
    [0020]
    [0021] Similarly, certain nasal masks work, US 6,532,961 B1 and US 6,520,182 B1. Another nasal with the possibility of adaptation is a pediatric mask, designed to grow with the child, the ES-2669063_T3, and there is also the ES-2441595_T3, which thanks to a retention wire, adapts to the face.
    [0022]
    [0023] There are alternatives that allow the dynamic interface as shown in USO-05560354-A; In this case you can alternate between a nasal and oronasal model thanks to its two spaces, however, despite the development of some options with dynamic interface, there is no model that can avoid pressure ulcers throughout the face.
    [0024]
    [0025] The entry of the air is done in most of the masks through the front, although there is some case in which it is accessed through the top as shown in document US 2016/0067439 A1. In other models it is introduced through the sides of the mask, as in some nasal olives, such as US 9,393,375 B2.
    [0026]
    [0027] There are cases that instead of using nasal masks, olives that penetrate slightly in the patient's nostril are used, as observed in US patent 2017 / 014392.6 A1.
    [0028]
    [0029] As already mentioned, normally the respiratory masks have a rigid external structure and a softer pad that is the one that will be in contact with the user's face, and all this is kept in position thanks to a strap that is held around head. Different patents deal with belts already designed to facilitate the placement of the mask, such as ES-2395221_T3, ES-2657201_T3, ES-2579943_T3, ES-2171257_T3, ES-2573473_T3, ES2561089_T3 and ES-2584304_T3.
    [0030] Therefore, it is intended to develop a modular mask for any user with respiratory impairments, from children to the elderly. Thus, we wanted to modify both the interface and its support.
    [0031]
    [0032] EXPLANATION OF THE INVENTION
    [0033]
    [0034] In order to solve the aforementioned problems, the invention proposes a modular respiratory mask comprising a carcass structure that delimits an interior space, a belt device configured to hold the carcass structure on the patient's face, at least one communication path to communicate the interior space of the carcass structure with at least one patient pathway selected between a buccal and a nasal passage, and a tubular structure to supply from the outside an air flow to the interior space of the carcass structure.
    [0035]
    [0036] The carcass structure comprises two opposite entrances in which they fit connecting end sections of the bifurcated tubular structure into two symmetrical branches that converge into a common branch; wherein said tubular structure comprises an inlet located in the common branch and two outlets located at the ends of facing couplings that include the end sections of the tubular structure.
    [0037]
    [0038] The carcass structure comprises an outer curved-concave surface that is configured to adapt to the curvature of a front part of the patient's face; wherein said carcass structure further includes two hitch extensions that are located in opposite extreme areas of the outer curved-concave surface of the carcass structure; and where said hitch extensions are configured to anchor end portions of the belt device therein.
    [0039]
    [0040] The carcass structure includes holes that are configured to detachably fit a plug-in nose olive to the patient's nostrils; where said nasal olives comprise a tubular configuration.
    [0041]
    [0042] A first embodiment of the invention, the carcass structure comprises a carcass and a pad having a configuration in the form of a recess with pairs of larger side walls, bottoms and pairs of smaller side walls that include facing windows that constitute the opposite entrances of the carcass structure for plugging into them the tubular structure; where the pad is configured to fit inside the housing in two different positions.
    [0043]
    [0044] The pad is anchored to the housing by means of a tongue and groove coupling formed by a shoulder that delimits a mouth of the housing and a recess of the pad.
    [0045]
    [0046] One of the major side walls of the pad includes the two holes that are configured to detachablely fit the plug-in nasal olives to the patient's nostrils.
    [0047]
    [0048] One of the larger side walls of the housing comprises an open recess that interrupts the continuity of the shoulder that delimits the mouth of the housing.
    [0049]
    [0050] In a first position of the pad, its larger side wall that includes the two holes is in contact with the larger side wall of the housing that does not include the open recess.
    [0051]
    [0052] In a second position of the pad, its larger side wall that includes the two holes is in contact with the larger side wall of the housing that includes the open recess, so that in this second position the holes are located in coincidence with said recess open.
    [0053]
    [0054] The pad includes a front opening delimited by a frame adjacent to the recess located at the confluence of said frame and the four side walls of said pad; where said frame includes the curved-concave surface that is configured to adapt to the curvature of a front part of the patient's face, around his lips covering the entire mouth.
    [0055]
    [0056] A second embodiment of the invention, the carcass structure comprises a curved tubular part, whose opposite entrances are located at the ends of said curved tubular part; where the holes that are set to fit in them the nasal olives, cross the wall that delimits said curved tubular piece. The carcass structure formed by the curved tubular part preferably has a quadrangular section, without discarding other sections.
    [0057]
    [0058] Each of the nasal olives includes an annular groove configured to fit in it the edge that delimits each of the holes of the carcass structure.
    [0059]
    [0060] The belt device comprises a belt, pairs of adherent areas located at some end sections of the belt and two quick engagement parts; where the quick hitch pieces include curved portions that engage in recesses of the hitch extensions; and where the end sections of the belt are attached to the two pieces of quick coupling.
    [0061]
    [0062] Thus, considering the first embodiment of the invention, the modular respiratory mask comprises several interchangeable components manufactured in three sizes some of them: the housing, the pad and the nasal olives. The innovative thing about this system is the possible combination of large housing structures with small nasal olives, and vice versa; as well as being able to exchange the different pieces in such a way that you can have an oronasal, nasal and buccal breathing without acquiring different masks.
    [0063]
    [0064] In line with what was said in the previous paragraph, the housing has three possible sizes to adapt to the morphology of the patients' faces. It will be manufactured with a sufficient curvature to accommodate the face, covering the entire surface of the mouth allowing speech, of polymeric material, transparent and rigid, since it gives the necessary consistency to the mask.
    [0065]
    [0066] The union with the belt device is made by the upper part of the sides of the housing, and the union with the tubular structure in the form of "Y" is carried out by the lower part. With this it is possible to place any of them of independent form The curved open recess located in the upper part of the housing facilitates the placement of the nasal olives in the pad.The union of the housing with the pad is made with the projection that will allow the fitting in the recess or groove of the pad.
    [0067] The pad of the first embodiment of the invention has three possible sizes according to the size of the housing, with its same shape for a complete adaptation; said pad of the front mouthpiece disposing in the contact area with the face of the width of the housing and the two smaller side walls to allow air to enter through its windows. These holes or side windows will be double the size of the tubular structure in the form of an "Y" inlet to allow its use in two positions (face up as an oronasal pad and face down as a mouth pad).
    [0068]
    [0069] The housing is manufactured with a transparent elastomer and will be symmetrical along two axes, with the exception of the existence of the two holes in which the two nasal olives fit. These holes will remain in the lower part of the housing when used as a mouthpiece. The thickness of the pad will be the same as the annular groove in the nasal olives.
    [0070]
    [0071] The contact area with the face will be of sufficient size so that despite the irregularities of the patient's face there are no leaks. The pad has the entire recess or recess in its entire exterior to allow the fit with the shoulder of the housing.
    [0072]
    [0073] Nasal olives are mushroom shaped in three sizes according to the morphology of the patient's nose. They are made of an elastomer material and are hollow inside so they can function as an accordion. The base of each nasal olive includes its annular groove that will be the same thickness as the pad and that the curved tubular part of the second embodiment of the invention; all this to be able to fit into them. For proper functioning, the upper part of the mushroom must be introduced into the patient's nostrils.
    [0074]
    [0075] The curved tubular part may be connected to the same Y-shaped tubular structure and to the nasal olives that are also used for the housing of the first embodiment of the invention. It will be manufactured with an elastomeric material but more rigid than the pad, since it must support the different accessories. Basically the curved tubular part comprises a curved tube of square section open at its ends where it joins the Y-shaped structure, and with the two holes in the upper area where the nasal olives that will have the same thickness will be placed than the annular grooves of the nasal olives. At the ends and in contact with the patient's face are the hooks of the belt device.
    [0076]
    [0077] The Y-shaped tubular structure will be made of an elastomeric material and will have at the two ends of the Y the same shape as the side openings of the housing of the first embodiment and the curved tubular part of the second embodiment. The part of the tubular structure will be the male that must fit into the openings of the housing and curved tubular part. It has a Y-shape, at the top to be able to reach both sides of the housing or curved tubular part, and at the bottom to join the standard tube of the respirator.
    [0078]
    [0079] The belt is made of a semi-elastic textile material. In addition, the belt includes the pairs of adhesive areas (velcro) located at the end sections of said belt to engage the two quick-engagement parts to be able to fix the mask to the user's face more precisely. The upper part of the strap will surround the patient's head as if it were a headband, while the fastening of the mask will be carried out by a lower part of the crossing strap, which will be held thanks to the upper part of the strap as a headband .
    [0080]
    [0081] The mask of the invention encourages the use of dynamic interface, which allows an oronasal mask to be both a buccal or a nasal, being able to rotate through these three types of mask with a single product. With the carcass structure models, the reversible pad, the set of nasal olives and the Y-shaped tubes (tubular structure), it can become the three different mask models, with all its advantages. Likewise, as the carcass structures are manufactured with transparent material and allow for their size and shape the conversation, the barrier between the patient and society is reduced.
    [0082]
    [0083] The housing of the first embodiment of the invention is transparent, which allows the vision of what happens inside the mask and thanks to its simple shape, the manufacturing process is also. It is a polymeric material, rigid and biocompatible.
    [0084]
    [0085] Said housing is responsible for being the structure of the whole set; where said housing connects by pressure with the "Y" shaped tubular structure and protects the pad, which being an elastomer can be deformed more easily. casing and pad joint is produced thanks to the protrusion of the carcass and the recess or recess that the pad has, so that when it is placed on the patient's face, its separation is prevented, at the same time when it is alone It can be easily disassembled thanks to the elasticity of the pad.
    [0086]
    [0087] The housing covers the entire mouth area, not only when it is closed, but also when the patient is talking or gesturing. It opens on the part where the nasal olives would be hooked to the pad, which allows the user to use the mask as an oronasal in a simple way.
    [0088]
    [0089] As for the second embodiment of the invention, which comprises the curved tubular part, it has sufficient curvature to adapt to the patient's face, it is made of a more elastic material than the first but rigid enough to hold the nasal olives, "Y" shaped tubular structure and belt device. In this case it has the necessary holes to allow the connection of the nasal olives and allow the nasal non-invasive mechanical ventilation. In addition, its two lateral ends are hollow, so that it connects with the "Y" shaped structure by pressure.
    [0090]
    [0091] In the case of wanting to use the mask as a mouthpiece, the housing with the pad will be used, which thanks to its symmetry, can be placed so that the holes touch the ground (one of the side walls) of the housing preventing leaks, thus facilitating all the supplied air to pass to the patient's mouth.
    [0092]
    [0093] Also due to its symmetry, its manufacturing is easier, thanks to the fact that the air inlet of the pad is through the windows located in the smaller side walls of the carcass structure, so that although the entrance of the shaped structure of "Y" is at the bottom of the housing and the pad is turned to the necessary position, the air intake can be facilitated.
    [0094]
    [0095] The belt device is attached to the two different housing structures that have the same type of quick coupler parts, allowing the mask to be placed and removed easily and quickly in case of an emergency. These hooks on the housing are located at the top, so that they leave the placement of the free "Y" shaped tubular structure (this is located at the bottom), the mask can be released without releasing said tubular structure, or vice versa.
    [0096]
    [0097] The nasal olives are responsible for making the air enter the nostrils, so they have a mushroom shape that allows the entry of the tip into the nostrils, so that when pressed on the nose it does not deform bending towards a lateral, but remains straight, facilitating the entry of air and performing its interface function well.
    [0098]
    [0099] The Y-shaped structure to allow the entry of air from both sides of the mask, allows to release the vision of the mouth, and thus obtaining a better face-to-face relationship with a patient. In the lower part of the Y-shaped structure there is a circular projection that corresponds to the vertical branch of the "Y", where said tubular projection corresponds to the diameter of the standard tube that connects to the respirator. Y shape is connected to the mask by pressure, ensuring that it does not leave its space.
    [0100]
    [0101] All this mechanism is supported thanks to the strap device that covers the patient's head, but releases the ears, which facilitates the use of other accessories such as glasses or hearing aids. This occurs because the strap is divided into two parts: a top in the form of a headband that is the one that supports the lower one and prevents it from slipping down the patient's neck, and a lower one that is the one that hooks to the mask through of the quick hitch parts; where said lower part is what keeps the carcass structure fixed to the face, preventing leaks.
    [0102]
    [0103] Because 3 sizes of the different components will be manufactured, you can create, for example, a mask with the large-sized buccal part and the small-sized nasal olives, and thus the other possible combinations, thus facilitating a better adjustment. There is also the possibility of releasing one of the nasal olives for those who use a nasogastric tube.
    [0104]
    [0105] Thanks to the decrease in the size of the mask, the face receives less pressure surface and consequently there will be less conflict points.

    [0119] PREFERRED EMBODIMENT OF THE INVENTION
    [0120]
    [0121] The innovation of this modular respiratory mask is that it can be used in three different ways; Oronasal, nasal and oral. For this, several pieces are necessary as shown in Figures 1a and 1b according to a first and a second embodiment of the invention, in addition to a belt device that can be seen in the figure 6.
    [0122]
    [0123] In figure 2 (first embodiment) it is shown how it would be used in the case of wanting to breathe both through the nose and mouth at the same time, thus exercising an oronasal mask, for this a housing (1), a pad (2 ) and nasal olives (3) must be placed in their position, and to connect to a respirator not shown in the figures, a Y-shaped tubular structure (4) will be connected, so that these components can be observed for example in figure 1a.
    [0124]
    [0125] In figure 3 it is mounted in the case of being used as a buccal. To do this, the nasal olives (3) of Figure 2 must be removed from the product and the pad (2) must be placed by turning it around, reversing its position to prevent leaks from holes (2.1) configured to fit the olives nasals (3), since when resting on the housing (1) the air cannot escape outside. These parts can be seen in Figure 1b.
    [0126]
    [0127] In Figure 4, a part of the mask mounted for use as a nasal according to the second embodiment of the invention is collected, so that in this case the housing (1) of Figure 2 and the pad (2) of the figure 2; and in this case the nasal olives (3) are attached to a carcass structure comprising a curved tubular piece (5) through its holes (5.1) said nasal olives being fixed (3) thanks to annular grooves (3.1) of the olives (3), and which in turn the tubular structure (4) is joined by the end sections of the curved tubular part (5) thanks to a male female tongue and groove joint.
    [0128]
    [0129] Figure 5 shows the assembly of a part of the oronasal mask according to the first embodiment of the invention; where the pad (2) joins the housing (1) thanks to a shoulder (1.2) that has the housing (1) and thanks to a recess (2.2) of the pad (2), so that a joint is created Male female. This joint is easy to separate when you want to change from oronasal to buccal, but it cannot be changed without removing the mask from the face, or without applying some force to remove the silicone pad (2) from the housing (1), which when being Flexible allows adjustment and release easily. In turn, the nasal olives (3) are attached to the pad (2) without having contact with the housing (1), thanks to the annular groove they have (3.1) that matches the thickness of the pad (2). The same happens in the case of the nasal olives (3) with respect to the curved tubular part (5) that are of the same thickness.
    [0130]
    [0131] As illustrated in Figure 6, in order to be able to attach the belt device to the shell structure of the mask, two quick engagement parts (6.3) are used that are attached to the shell (1) or to the curved tubular part (5). ), thanks to its hook extensions (1.1, 5.2) located in extreme areas of the housing and curved tubular part 5, respectively. The belt device can be attached to both the hitch extensions (1.1) of the housing (1) and the curved tubular part (5) because both hitch extensions (1.1, 5.2 se) are equal and compatible with the quick hitch parts (6.3).
    [0132]
    [0133] For the proper use of the mask, as shown in figure 2, the pad (2) must be in contact with the patient's face and, in turn, surrounding the mouth in order to allow air to enter. On the other hand, the nasal olives (3) should slightly penetrate the patient's nose allowing air to enter the nostrils.
    [0134]
    [0135] In Figure 3, when the mask is used orally, simply the pad (2) must be in contact with the patient's face and surrounding his mouth, ensuring that the holes (2.1) of the pad (2) are in the lower part in contact with the housing (1).
    [0136]
    [0137] To use the nasal mask, as shown in Figure 4, the nasal olives (3) must penetrate slightly into the user's nose, while the curved tubular part (5) must rest on the patient's face above of the upper lip of said patient without covering his mouth allowing speech.
    [0138]
    [0139] The housing comprises an open recess (1.3) that interrupts the continuity of the projection (1.2) that delimits the mouth of the housing (1), so that said open recess (1.3) allows the nasal olives (3) to fit over the holes ( 2.1) of the pad (2) thanks to the location of the open recess (1.3).
    [0140]
    [0141] On the other hand, the Y-shaped tubular structure (4) includes two facing end sections (7) that are intended to fit in opposite entrances of the structure of housing the two embodiments of the invention to supply the necessary air to the patient; so that in the case of the curved tubular part (5) (second embodiment of the invention) the opposite entrances correspond to the open ends of said curved tubular part (5), while in the case of the carcass structure of In the first embodiment of the invention, the opposite entries correspond to pairs of aligned windows of the housing (1) and of the pad (2).
    [0142]
    [0143] The belt device comprises the belt (6) itself, the two quick-coupling parts (6.3), an upper section (6.1) of the belt (6) as a headband that is attached to the top of the head of the patient, a lower cross section (6.2) of the belt (6) that is located behind the bottom of the head, and a couple of adhesive areas located at some end sections of the belt (6).
    [0144]
    [0145] As for the belt device, as shown in Figures 6, 7 and 8, as already mentioned above, it comprises the two quick coupler parts (6.3) that are configured to be able to be attached to both the housing (1) as to the curved tubular part (5) thanks to its hook extensions (1.1, 5.2) that include recesses in which curved portions are introduced that are part of the quick hook parts (6.3).
    [0146]
    [0147] In addition, the belt device includes the pairs of adhesive areas (6.4) located at the end sections of a belt where the quick coupler parts (6.3) are attached, passing inside to be able to fix the mask to the patient's face more accurate.
    [0148]
    [0149] To avoid discomfort of the belt device on the patient's face and to be able to release the area of the ears and to be able to use different accessories, such as hearing aids or glasses, the upper section (6.1) of the strap (6) will surround the head of the patient as if it were a headband, while the strong hook to the mask will be the lower cross section (6.2) of the belt (6), which thanks to the upper section (6.1) of said belt (6) will not release from the head , thus maintaining the mask in the correct position and consequently avoiding leaks and ulcers due to a bad placement of the mask.
    [0150] Finally, the Y-shaped tubular structure (4) will be attached to the respirator tube (not shown in the figures) to make the connection between respirator and mask.
