DESCRIPTION

RESPIRATORY MASK WITH SIDE SUPPORT SYSTEM

Object of the invention

The object of this report is a respiratory mask with a lateral fastening system, and whose special distinctive feature lies in the fact of implementing fins that exert lateral pressure on the cheek area that provide a special fastening to the face of the patient. user, so that it allows an absolute adaptability of the mask to the face of the person who wears it, avoiding the discomforts that today involves wearing a mask, especially for those users who must wear glasses.

Background of the invention

At present, in the field of individual protection against external agents in aerosol format, such as respiratory viruses or similar, there has been a great advance in terms of solutions that seek to filter the particles or droplets present in the environment and that if they are are infected with viruses, they can infect a healthy person if they are in a contaminated environment long enough.

Various masks grouped into classes are known in the state of the art, such as: hygienic, surgical masks, FFP1, FFP2 and FFP3 (the latter being able to carry an exhalation valve).

Most of these masks have several main drawbacks, including two, firstly, a pressure on the outer cartilaginous area of the ears that can cause deformations in their shape (especially in children) to small lacerations. due to prolonged use; and secondly, the problem that arises in people who wear glasses, who have to continuously clean their glasses as a consequence of the fogging produced by the mist that is produced when exhaling the air.

To alleviate this problem, there are various solutions in the state of the art that attempt to solve said problems, thus, for example, utility model ES 1263784 U describes an adhesive / adherent mask that, consisting of a surgical or textile mask, of which comprises at least one main body, which in position of use covers The mouth and nose of the user, and which may or may not comprise elastic straps or tapes for fastening the ears or the back of the head, is characterized by comprising an additional fastening element which is constituted by at least one band adhesive / adherent that, made of variable materials, substances or treatments, is incorporated into the internal part of the body of the mask and can be pasted directly on the user's face.

Said mask is configured as a means of protection by means of an additional attachment to the user's face, thus solving (at least partially) the problem of holding the user's ears, but it does not solve the problem of fogging of the user's glasses as This is how the invention proposed here does.

The utility model ES 1262 555 U describes an ergonomic protective mask, characterized in that it comprises a central body, which covers the bucco-nasal part of the user who wears it, and from both ends of the central body, there are two extensions that extend until reaching to the crown of the user's skull by joining its ends by means of joining.

Said invention proposes an alternative means of fastening, to that used by means of ear strips, with a fastening on the back of the user's head, although this fastening is carried out with a magnet or a hook that will foreseeably make that user uncomfortable. to wear the mask, not solving the problem of fog in the glasses of those users who need to wear glasses to see or to protect themselves from the sun.

To alleviate the problem of fogging in masks, the applicant is aware of the existence of the utility model ES 1263080 U that describes an anti-fog holding device for masks consisting of:

- An adaptable pressure element, made up of a piece of flexible material with a moldable element inside, which allows the shape of the assembly to be adjusted, making it possible to exert uniform pressure on the upper edge of the mask against the user's face.

- A fastening element, consisting of one or more cords or elastic tapes, for their placement around the ears, neck and / or head of the user, fixing the position of the adaptive pressure element in the right place.

This solution presents a device that is applied to the external area of the nasal bridge by applying pressure to the mask, which will foreseeably prevent the expulsion of air over the glasses, preventing them from fogging up. But the problem with the laceration in the area where the mask is attached will continue to be present.

The same happens with the utility model ES 1257471 U that describes a sanitary mask with anti-fog protection of those that comprise filtration media such as special woven fabrics, or not, with support means on the user's head, such as elastic tapes, arranged at their lateral ends and, an adapter wire located on the outer face of the mask to be able to adapt to the nose and profile of the user, characterized in that on the inner face of the mask and at the appropriate height, according to the profile of In the user's nose, a separating sheet is incorporated between the upper and lower part of said mask, the sheet located in a substantially horizontal position on said inner face and immobilized thereto by any known means.

The utility model ES 1 253 812 describes a mask without fastening cords characterized in that it consists of four fundamental parts: any textile mouth mask, a group of adhesive positioning elements for attachment to the face, a group of adhesive forming elements. for its adjustment to the nose, and a handle element to be able to grip the mask when it is not in use.

Similarly, utility model ES 1249 279 describes a protective mask, comprising: an inner surface intended to cover at least the nose and mouth of a user, human or animal; an outer surface, and a suitable contour to rest on the user's face; and means of attachment to the user; characterized in that said fixing means comprise an adhesive fixed in an area adjacent to the contour of the mask and suitable for fixing all or part of said contour to the user's face.

Utility model ES 1255401 describes an improved mask, consisting of a mask that is fixed to the face by joining neodymium magnets, characterized as it is made up of a piece of protective material to which several neodymium magnets are glued with cyanoacrylate.

The utility model ES 1247 899 describes a mask for oral, nasal or or nasal protection, which is formed by a filtering material and is capable of being fixed on the mouth and / or on the nose of the user, characterized in that a band is arranged perimeter. adhesive on the part of the mask that is placed on the wearer's skin.

These latest inventions employ strategically placed adhesion elements (adhesives or magnets) to the user's face (mainly in the area of the user's nose) to fix the mask to the user's face. However, this type of solution has the main drawback of reusing the masks (not having problems with hygienic masks since they have a relatively short useful life) or with the entry of pathogens from the sides, where they continue to have problems for your adherence in most cases.

None of the solutions described here solves the problem as the invention described here does, namely, achieving a respiratory mask (reusable) that protects by filtering against external agents (such as respiratory viruses) and that at the same time Once, be able to achieve a firm and natural fit (avoiding possible discomfort in the external area of the ears, head or neck) that allows the wearers of glasses (both prescription and sunglasses) to safely wear said glasses, without them fogging up.

Description of the invention

The technical problem solved by the present invention is to achieve a mask with a firm and natural fit that allows its user to wear the mask in a safe and comfortable way that allows a grip by contact at various points, preventing the air expelled by the user from fogging contact glasses or sunglasses. For this, the respiratory mask with a lateral fastening system, object of the present utility model, comprises a chassis on which a layer of fabric is fixedly attached; and that it is characterized in that the chassis is made up of a first segment with an oblique shape that allows it to be placed from the area of the user's nose to the chin, and on said first segment joined to second segments of a convex character integrally attached to the respective fins that by means of third segments are joined with the lower area of the first segment; all covered by the fabric with high filtering properties.

Thanks to its design, the invention proposed here allows a fixation through four attachment points: intermediate part of the nose, lower part of the chin and on each of the user's cheeks (by means of two lateral wings that press the mask against the face user). In this way, the user will be able to wear the mask in a natural way, avoiding the discomforts that currently occur with the use of hygienic, surgical or FPP2 masks.

The mask recommended here adapts to the user's face, achieving such tightness throughout its perimeter that it increases safety in its use, since it does not have free spaces through which virus particles can enter in the form of aerosols.

In the same way, the contact area of the mask is specifically designed to have a gentle contact with the skin, and thus avoid possible injuries in the form of scratches or the like.

In addition, the malleability (and in turn, firmness) of the structure that makes it up, allows a correct adaptability to any face, regardless of its shape or physiognomy, this enables the mask presented here to be used in a wide range of sectors or age segments, from children to adults or the elderly.

The structure or chassis that makes it up has a frontal septum that passes from the nose to the chin, generating a recess as an air chamber coinciding with the user's mouth area, which facilitates and improves the breathing of clean air. , such as exhaling in a safe and controlled manner.

Finally, as a consequence of the above, the mask described here can be placed with the same ease as putting on a goggle, that is, with minimal pressure on the user's face, the chassis will open in such a way that produces a correct grip on the surface of the user's face, and thus, be correctly adapted to it, avoiding possible entry of pathogens through the gaps that generally remain in the area of the user's cheeks, thus minimizing the risk of contagion.
