Description

Protective mask for protection of the upper respiratory tract

Field of technology

The technical solution concerns consumer or protective work aids and at the same time the design solution of the aid for the everyday life of the citizen.

Prior art

Currently, there are various aids on the market to cover part or all of the face, whether they are compact respirators, cotton drapes with rubber eyelets, straps or other textile cords for tying, or a transparent face cover made of hard plastic. These systems are usually associated with a short shelf life, when they must be discarded or treated for further use at the end of their service life. Another disadvantage, especially of respirators, is their high weight and, in many cases, imbalance due to the placement of filters, which has a negative effect on the cervical spine during long-term wear. Another disadvantage is the opacity of these aids, which makes communication difficult, for example, with people who watch.

The essence of the technical solution

The above-mentioned shortcomings are largely solved by a protective mask according to this technical solution, which consists of a front viewing surface of the mask, made of a transparent material which is solid and covers the upper respiratory tract. Holes are made in the transparent material on the sides for the attachment of holders of replaceable filters, eg HEPA filters, or cosmetic tampons, which show excellent retention not only of dust, pollen, but also bacteria and viruses. The circumference of the mask is detachably connected to a sealing part which is made of a soft material, preferably silicone. Thanks to this type of material, it adheres to the face and seals well. At least two fastening elements are made in the rear part of the mask for fastening straps for fastening the mask to the face, or the strap is part of the rubber seal of the mask. The filters are placed in a filter holder, which fits on the holes in the mask, they are also made of a flexible material that adheres to the mask and seals.

The filter holder is universal for various types of filter inserts, and is adapted for the possibility of using special cosmetic tampon carriers, also serving as filters, which are attached to the filter holder by means of clips or a tongue-and-groove system, or by means of an I-shaped or T-shaped insertion profile. or V, circular and the like. Another option is to attach the fan to a filter holder for air intake to facilitate breathing, or other similar devices

The advantage of this design is the transparency of the mask, its tightness, easy replacement of available filters, its lightness and balance and its multiple use, because after removing the filter it can be washed with hot water, boiled or chemically cleaned or otherwise sterilized and used. repeatedly.

Example of implementing a technical solution

The protective mask for the protection of the upper respiratory tract consists of a front transparent visible cover surface which has openings 2 for filter holders 3 formed on its sides and four holders 5 for mask fastening straps are made on the back side of the cover surface 1. The holders 3 of the filters 4 are adapted for the possibility of attaching special carriers 6 of cosmetic tampons, where these can be attached to the holder 3 which is inserted into the opening 2 of the protective mask. The holder 3 without special carriers 6 of cosmetic tampons can contain, for example, a HEPA or ULPA filter, thus increasing the filtration efficiency of the mask. The attachment of the cosmetic tampon carriers 6 to the holder 3 is solved by means of clips or a tongue-and-groove system, or by means of an I-shaped, T-shaped, or V-shaped, circular, and the like.

The circumference of the mask is detachably or non-detachably connected to a sealing part 7, which is made of a soft material, preferably silicone. Thanks to this type of material, it adheres to the face and seals well, without pushing the wearer.

Industrial applicability

This technical solution can be used wherever it is necessary to filter the air for breathing, both from impurities and from bacteria and viruses.
