Description

DESCRIPCIÓN DESCRIPTION
Mascarilla. Face mask.
SECTOR DE LA TÉCNICA TECHNICAL SECTOR
La presente invención se refiere a una mascarilla, del tipo de las destinadas a proteger a su portador de la inhalación de atmósferas peligrosas, susceptibles de contener virus, bacterias, gérmenes, humos, vapores, gases y partículas en suspensión, sirviendo al mismo tiempo como barrera de protección a terceros frente a la propagación de dichos elementos patógenos procedentes del propio portador de la mascarilla. The present invention relates to a mask, of the type intended to protect its wearer from inhaling dangerous atmospheres, likely to contain viruses, bacteria, germs, smoke, vapours, gases and suspended particles, serving at the same time as barrier to protect third parties against the spread of said pathogenic elements from the wearer of the mask.
El objeto de la invención es proporcionar una mascarilla mediante la que se optimice el proceso de respiración a través de la misma, de modo que a través de su nueva estructura impida inhalar el dióxido de carbono que el propio portador expulsa durante el uso de dicha mascarilla. Esta estructuración conlleva una ventaja adicional, como es el hecho de evitar el empañado de gafas, bastante habitual y molesto en el uso de este tipo de dispositivos. The object of the invention is to provide a mask by which the breathing process through it is optimized, so that through its new structure it prevents inhaling the carbon dioxide that the wearer expels during the use of said mask. . This structure entails an additional advantage, such as the fact of avoiding fogging of glasses, quite common and annoying in the use of this type of device.
La invención es aplicable tanto a mascarillas desechables como reutilizables, en virtud de una estructura sencilla y consecuentemente económica. The invention is applicable to both disposable and reusable masks, by virtue of a simple and consequently cheap structure.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, el uso de mascarillas durante largos periodos de tiempo hace que, por la propia estructura de la misma, el usuario acabe inhalando su propio aire expirado, de manera que, si bien esto no es un problema durante breves periodos de tiempo, puede suponer graves problemas durante largos periodos de uso, pudiendo llegar a provocar hipoxia. As is known, the use of masks for long periods of time means that, due to its very structure, the user ends up inhaling their own expired air, so that, although this is not a problem for short periods of time, can cause serious problems during long periods of use, and can even cause hypoxia.
Paralelamente, este tipo de dispositivos presenta un problema adicional, como es el hecho de que el aire caliente que se expulsa a través de los pulmones fluye al menos de forma parcial en sentido ascendente, lo que suele provocar el empañamiento de los cristales de las gafas de los usuarios que porten este tipo de accesorios, pudiendo ser un problema muy serio en caso de precisar gafas de ver para, por ejemplo, conducir. Finalmente, cabe destacar el hecho de que este tipo de mascarillas incluyen medios de filtrado cuya función es la de filtrar el aire expulsado por el usuario, es decir que su función es la de proteger al resto de personas próximas al usuario, de posibles virus, bacterias o gérmenes. At the same time, this type of device presents an additional problem, such as the fact that the hot air that is expelled through the lungs flows at least partially in an upward direction, which usually causes fogging of the glasses' lenses. of users who carry this type of accessories, which can be a very serious problem if they need glasses to drive, for example. Finally, it is worth noting the fact that this type of mask includes filter media whose function is to filter the air expelled by the user, that is, its function is to protect the rest of the people close to the user, from possible viruses, bacteria or germs.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La mascarilla de la invención resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero de gran eficacia. The mask of the invention fully and satisfactorily resolves the aforementioned problems, based on a simple but highly effective solution.
Para ello, la mascarilla de la invención parte de la estructuración de este tipo de mascarillas, indistintamente si es de tipo desechable o reutilizable, al aportar una solución sumamente económica, de manera que la mascarilla centra sus características en el hecho de incorporar una banda transversal en su zona media superior, que obliga a la mascarilla a ajustarse en dicha zona sobre la zona del labio superior, por debajo de la nariz, de modo que la mascarilla defina dos zonas de trabajo diferenciadas y aisladas, una para la nariz y otra para la boca. For this, the mask of the invention starts from the structuring of this type of mask, regardless of whether it is disposable or reusable, by providing an extremely economical solution, so that the mask focuses its characteristics on the fact that it incorporates a transverse band in its upper middle area, which forces the mask to fit in that area on the upper lip area, below the nose, so that the mask defines two differentiated and isolated work areas, one for the nose and another for mouth.
La citada banda transversal se situará sobre la cara externa de la mascarilla, si bien podría disponerse internamente entre las capas que participan en el cuerpo principal de la mascarilla y fijada a la capa externa, o bien ligada a su cara interna. The aforementioned transverse band will be located on the external face of the mask, although it could be arranged internally between the layers that participate in the main body of the mask and fixed to the external layer, or linked to its internal face.
De forma más concreta, la banda transversal adicional incluye medios para regular la longitud de la misma, y permitir así una mejor adaptabilidad a la fisonomía de cada usuario en concreto, de modo que la misma, una vez regulada con respecto a los bordes laterales de la mascarilla a los que se vincula, se ve sometida a tracción y por lo tanto presiona en su zona de aplicación transversal sobre el cuerpo principal de la mascarilla sobre la zona del labio superior, es decir entre la nariz y la boca, determinando así dos cámaras independientes, la superior para inspirar y la inferior para espirar. More specifically, the additional transverse band includes means to regulate its length, and thus allow better adaptability to the physiognomy of each specific user, so that it, once adjusted with respect to the lateral edges of the the mask to which it is linked, is subjected to traction and therefore presses in its transversal application area on the main body of the mask on the area of the upper lip, that is to say between the nose and the mouth, thus determining two independent chambers, the upper one to inspire and the lower one to exhale.
Opcionalmente, la banda transversal podría ser elástica. Optionally, the transverse band could be elastic.
A partir de esta estructuración, se derivan las siguientes ventajas: • Quedan separadas las zonas de inspiración y la de espiración de forma que el aire inspirado deja de estar viciado como ocurre en los modelos existentes en la actualidad, donde ambos gases se mezclan en el espacio existente entre la mascarilla y el área de la boca-nariz del usuario, que provoca la respiración de aire viciado. From this structure, the following advantages are derived: • The inspiration and expiration zones are separated so that the inspired air is no longer stale, as is the case in currently existing models, where both gases mix in the space between the mask and the mouth area. user's nose, which causes the breathing of stale air.
• Al quedar la zona de espiración únicamente por debajo de la nariz, se elimina además la problemática del empañamiento de las gafas. • As the exhalation area is only below the nose, the problem of fogging of the glasses is also eliminated.
• Al quedar establecidas dos zonas separadas, se puede aplicar un tipo de filtro diferente a cada una de las zonas, siendo a la vez protectoras para el usuario y para los demás. • By establishing two separate zones, a different type of filter can be applied to each of the zones, being both protective for the user and for others.

La figura 1.- Muestra una vista en perspectiva de una mascarilla realizada de acuerdo con el objeto de la presente invención, en situación de uso. Figure 1.- Shows a perspective view of a mask made according to the object of the present invention, in use.
La figura 2.- Muestra una vista en perfil transparente del conjunto de la figura anterior. Figure 2.- Shows a transparent profile view of the assembly of the previous figure.
REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas, puede observarse cómo la mascarilla de la invención se constituye a partir de un cuerpo principal (1-1’) de naturaleza filtrante, ya sea desechable o reutilizable, formal y dimensionalmente adecuado para cubrir la zona de la nariz (3) y boca (4) de su usuario, y en el que participan una pareja de bandas (2) generalmente elásticas, para su fijación, ya sea a las orejas del usuario, o rodeando por detrás la cabeza del usuario. Pues bien, de acuerdo ya con la esencia de la invención, se ha previsto que la mascarilla incorpore una tercera banda (5) dispuesta transversalmente y afectando a su zona media superior, en correspondencia con la zona comprendida entre la nariz (3) y la boca (4) del usuario, ya sea vinculada a su cara externa o internamente entre las capas que participan en el cuerpo principal de la mascarilla o bien vinculada a su cara interna, y que se vincula a la mascarilla en sus bordes laterales (5’) a la altura determinada por la posición de la propia banda. In view of the figures outlined, it can be seen how the mask of the invention is constituted from a main body (1-1') of a filtering nature, either disposable or reusable, formally and dimensionally adequate to cover the area of the nose (3) and mouth (4) of its user, and in which a pair of generally elastic bands (2) participate, for fixing, either to the user's ears, or surrounding the user's head from behind. Well, in accordance with the essence of the invention, it has been planned that the mask incorporates a third band (5) arranged transversely and affecting its upper middle area, in correspondence with the area between the nose (3) and the mouth (4) of the user, either linked to its external face or internally between the layers that participate in the main body of the mask or linked to its internal face, and that is linked to the mask at its lateral edges (5' ) at the height determined by the position of the band itself.
La banda transversal (5) presentará una longitud regulable para una adaptación perfecta a la fisonomía del usuario, siendo en ese caso la tercera banda (5) transversal elástica, de manera que se vincule inamoviblemente a uno de los extremos (5’) laterales de la mascarilla, mientras que en el extremo contrario se vincule a través de un ojal, orificio (6) o similar a través del que poder acortar la longitud de la banda elástica a criterio de cada usuario, de modo que la misma se estabilice mediante anudado (7) o por cualquier otro medio convencional, como hebillas, cierres de bloqueo tubular tipo tanka, uniones tipo velero®, gafetes, corchetes, etc. The transverse band (5) will have an adjustable length for a perfect adaptation to the user's physiognomy, in this case the third transverse band (5) being elastic, so that it is irremovably linked to one of the lateral ends (5') of the mask, while at the opposite end it is linked through an eyelet, hole (6) or similar through which the length of the elastic band can be shortened at the discretion of each user, so that it is stabilized by knotting (7) or by any other conventional means, such as buckles, tanka-type tubular locking closures, Velero®-type joints, name tags, brackets, etc.
Opcionalmente, la tercera banda (5) transversal podrá vincularse de forma regulable a ambos extremos (5’) laterales de la mascarilla. Optionally, the third transverse band (5) can be linked in an adjustable way to both lateral ends (5') of the mask.
Esto permite ajustar la presión sobre el labio superior, asegurando una óptima independización de la zona de la nariz y la zona de la boca, tal como muestra la figura 2. This allows the pressure on the upper lip to be adjusted, ensuring optimum separation of the nose and mouth areas, as shown in figure 2.
A partir de esta estructuración se consigue, como se ha explicado con anterioridad, obtener dos zonas de trabajo para la mascarilla, lo que evita respirar el aire exhalado, aire que se expulsará por la zona inferior de la mascarilla, a través de la boca, lo que evita el empañamiento de gafas, además de permitir que, los dos sectores (1) y (T) del cuerpo principal de la mascarilla incluyan medios de filtrado distintos, en función del sentido de flujo previsto para los mismos, de modo que el sector superior (1) incluya medios de filtrado para el aire entrante, mientras que el sector (T) incluya medios de filtrado específicos para el aire saliente. From this structuring it is possible, as explained previously, to obtain two work zones for the mask, which avoids breathing the exhaled air, air that will be expelled through the lower part of the mask, through the mouth, which prevents goggles from fogging, in addition to allowing the two sectors (1) and (T) of the main body of the mask to include different filtering media, depending on the direction of flow planned for them, so that the upper sector (1) includes filter media for incoming air, while sector (T) includes specific filter media for outgoing air.
