Description

DESCRIPTION

Reusable mask

TECHNICAL SECTOR

The present invention refers to a reusable mask, of the type used as a means of protection against viruses, germs and bacteria present in the air.

The invention pursues the following objectives:

• Provide a transparent mask, highly reliable from the point of view of isolation of the user's airways, by virtue of a high degree of adaptability to different users' physiognomies.

• Provide a reusable mask, reducing the contamination associated with the use of this type of device compared to single-use devices.

• Ensure that exhaled air is not re-inhaled by preventing excessive inhalation of CO2.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, the masks used as a means of protection against viruses, bacteria and germs, such as surgical, sanitary, FFP2, N95, fabric masks, although they can have different configurations, have the common denominator of a poor adaptability to the physiognomy of the user, defining spaces between the mask and the user's face that allow the passage of aerosols, with the consequent risk of contagion, to which must be added the fact that the poor adaptability to the area of the The user's nasal septum, also causes the fogging of glasses, with the consequent annoyance that this entails.

At the same time, another problem with this type of mask is the possibility of re-inhaling the exhaled air, with a high CO2 content, with the consequent risk that this entails.

Finally, to say that the use of disposable masks is a very important environmental problem, since a large part of them is not recycled properly.

EXPLANATION OF THE INVENTION

The reusable mask that is recommended solves in a fully satisfactory way the problems mentioned above, based on a highly effective solution.

To this end, the mask of the invention is embodied in a body made of transparent silicone, which has the particularity that instead of adapting superiorly to the user's face at the intermediate height of the nasal septum, a septum that can have a substantially different depending on the user in question, it does so by adapting to the area that is defined between the upper lip and the nose, to which it adapts with great accuracy by virtue of its silicone-based nature and the minor physical irregularities that it presents. the face of a user in this area.

More specifically, the aforementioned main body of the mask is adapted through its lower end to the user's chin through a flange with a series of folds that give it a bellows-like structure that facilitates stable coupling to any chin.

Superiorly, the body of the mask conforms to the shape between the upper lip and the user's nose through a transverse flange arched in the lower direction, which together with a second flange parallel to it and arcuate in the upper direction define a chamber of inhalation that extends laterally to the respective zones in which large windows are included in which respective filters are intended to be interchangeably coupled.

These windows are larger than the inhalation chambers so that On the filtering surface, two operative zones are defined for said windows, a smaller zone, through which the inhalation of filtered air is produced through the inhalation ducts or chambers, and a zone for expulsion of the exhaled air. through the mouth, below said chambers and communicating with the main body of the mask.

According to another of the essential characteristics of the invention, in the central area of the inhalation chamber and in correspondence with the upper flange that delimits this chamber, the inclusion of a pair of holes formally and positionally coincident with the holes has been provided. of the nostrils, holes in which tubes of short length will be attached, intended to fit tightly to the user's nostrils.

The device thus described offers two independent circuits for inhalation and exhalation, respectively, with a high degree of tightness, which avoid inhaling previously exhaled air.

As is conventional, the body of the mask will be attached to the wearer's head through elastic bands or similar elements that will be attached externally to the sides of the main body of the mask.

The device thus described could incorporate a small perimeter upper of low height, as a means of concealing the tubes intended to be inserted into the nostrils.

The preferably transparent nature of the mask allows other people to see the gestures that the user makes when speaking, which is of great help for people with hearing disabilities.

Similarly, by only requiring the replacement of the filters associated with the aforementioned windows, the volume of waste generated by their use is significantly reduced.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 2.- Shows a front perspective view of the device of the previous figure.

Figure 3.- Shows a rear perspective view of the device of the previous figures.

Figure 4.- Shows a view similar to that of figure 3, but in which the mask appears sectioned by an imaginary vertical plane.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the mask of the invention is constituted from a main body (1), made of silicone, preferably transparent silicone, which extends over the user's face from the area that is defined between the upper lip and the nose, up to the chin area.

To ensure perfect tightness in the chin area, the main body (1) has been provided with a lower flange (2) with a plurality of zigzag folds (3) so that, being made of silicone, it determines a kind of bellows-like structure that adapts by elastic deformation to fit the physiognomy of the chin of the user.

For its part, in correspondence with the upper edge of the main body (1) of the mask, a transverse flange arched in the lower direction (4) is established, which together with a second flange (5) parallel to it and arched in the upper direction define an inhalation chamber (6) that extends laterally until it reaches the sides of the main body (1) where a pair of large windows (7) are established in which respective filters are interchangeable to fit.

The use of two opposingly arched flanges facilitates the manufacture of the mask by molding, and more specifically its demoulding at the level of said inhalation chamber (6).

As mentioned above, the windows (7) are significantly larger than the lateral outlets of the inhalation chamber, so that said windows also affect the main chamber that determines the main body (1) and which has the exhalation chamber function (8).

In this way, the filters that are located in each window (7) make it possible to filter independently, both the inhaled air and the exhaled air.

Regarding the inhalation process, in the central zone of the transverse arched flange in the lower sense (4) a pair of holes (9) are established that give access to the inhalation chamber.

Small tubes (10) are intended to be integrated into these holes, those shown in Figure 5 that fit tightly to the user's nostrils.

These elements can be part of the main body of the mask itself, or be a separate piece, as shown in figure 5.

For its part, the lateral ends of the main body (1) of the mask will be finished off in two semi-planes (11) for a better fit to the user's face.

Next to this area, some supports (12) will be established for the mask fixing tapes (13).

Finally, and purely aesthetic, the main body of the mask incorporates in correspondence with its upper edge a perimeter flange (14) of low height, determining a means of concealment of the tubes (10) destined to be inserted into the nostrils. .
