Description

Protective mask

Technical Field

The application relates to, specifically is a protective facial mask.

Background

At present, the protective mask is a sanitary article and is used for filtering air entering the mouth and the nose so as to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, and a large amount of protective masks are needed due to epidemic prevention and control; current protective facial mask includes gauze mask body and frenulum, during the use, wears the gauze mask body at face through the frenulum, and this internal nose strip of pressing of rethread gauze mask is moulding for the upper end laminating face of gauze mask body.

However, the existing protective mask has the following defects: after long-term wearing, the marks on the nose, the cheekbones and the upper edges of the ears are obvious (especially for short-hair people, the lacing is easy to slide and slide along with the movement of the head), even the laces are broken, the pressure injury is caused, and the recovery is difficult; and the upper end of the mask body is not in enough fit with the face, and the sealing performance is poor.

Therefore, how to improve the existing protective mask to overcome the above disadvantages is a problem to be solved by those skilled in the art.

Disclosure of Invention

An aim at of this application provides a simple structure, can avoid the appearance of pressure nature damage, wears the high protective facial mask of comfort level.

In order to achieve the above purposes, the technical scheme adopted by the application is as follows: a protective mask comprises a mask body and a strap; the protective mask further comprises a pressure reducing part, wherein the pressure reducing part is arranged on the frenulum and used for reducing the pressure of the frenulum on the ears.

Preferably, the pressure reducing part is slidably provided to the tether; the protective mask further comprises a locking piece, the locking piece is arranged between the decompression portion and the laces, and the locking piece is used for limiting relative sliding between the decompression portion and the laces. The advantages are that: when the pressure reducing part is used, the pressure reducing part is slid to adjust the position, then the locking piece limits the sliding of the pressure reducing part, so that the position of the pressure reducing part can be adjusted according to the requirements of different users, the position needing pressure reduction can be accurately positioned, and the universality is improved.

Preferably, the pressure reducing part has an annular structure, and the pressure reducing part is sleeved on the lacing; the locking piece includes that first pasting layer and first isolation layer, first pasting the layer set up in the interior anchor ring of decompression portion, first isolation layer set up in first pasting the layer skew one side of decompression portion. The advantages are that: the pressure reducing part is of an annular structure and is sleeved on the lacing, so that relative sliding between the pressure reducing part and the lacing is realized, and the pressure reducing part and the lacing are convenient to mount. When the sliding of the decompression part needs to be limited, the first isolation layer is taken down, and the decompression part and the lacing are adhered together through the adhesive layer.

Preferably, the locking member further includes a pulling member, the pulling member is located between the first isolation layer and the lace, one end of the pulling member is connected to one end of the first isolation layer, and the other end of the pulling member extends to the outside of the decompression portion. The advantages are that: the first isolation layer can be taken out by pulling the pulling piece outside the decompression part, so that the operation is simple and the use is convenient.

Preferably, the protective mask further comprises a sealing strip, and the sealing strip is arranged at the upper end of the inner side of the mask body. The advantages are that: when in use, the sealing strip can be shaped through the nose pressing strip in the mask body; the sealing strip can increase the attaching degree of the mask body, improve the sealing performance and reduce the pressure of the mask body on the nose and cheekbones.

Preferably, the cross section of the sealing strip is of a rectangular structure. The advantages are that: this facilitates shaping of the sealing strip by the nose strip.

Preferably, a first adhesive layer is arranged on one side, deviating from the mask body, of the sealing strip, and a first isolating layer is arranged on one side, deviating from the mask body, of the first adhesive layer. The advantages are that: when the mask is used, the mask body is adhered to the face through the second adhesion layer by the second isolation layer, so that the positioning and limiting effects are achieved, and the sealing strip can accurately reduce the pressure of the nose and the frontal bone; simultaneously, can further improve the laminating degree of gauze mask body and facial, further improve the seal.

Preferably, the width of the sealing strip is 0.6cm-1.2 cm. The advantages are that: when the material, the length and the thickness of the sealing strip are fixed, the smaller the width is, the more difficult the shaping is through the nose pressing strip, and when the width of the sealing strip is less than 0.6cm, the shaping is difficult; under the condition that the material, the length and the thickness of the sealing strip are fixed, the larger the width is, the more easily rebounded after being shaped is, and when the width of the sealing strip is larger than 1.2cm, the rebounded easily occurs; when the width of the sealing strip is 1cm, the comprehensive performance is optimal, and the cost performance is highest.

Preferably, the sealing strip protrudes outwards from a side of the protective mask, which is offset from the protective mask, so that the thickness of the sealing strip gradually increases from top to bottom and then gradually decreases. The advantages are that: this kind of structure makes sealing strip laminating face can further improve gauze mask body further improves the seal with facial laminating degree.

Preferably, the sealing strip and/or the pressure relief portion are made of a medical foam dressing. The advantages are that: compared with other pressure reducing auxiliary materials (such as medical hydrocolloid, air sac and the like), the medical foam dressing has better pressure reducing effect.

Compared with the prior art, the beneficial effect of this application lies in: when wearing, decompression portion can effectual reduction the pressure of frenulum to ear department can avoid ear department to rein in the trace obvious, and the skin is broken etc. even, causes the appearance of pressure nature damage. Therefore, the protective mask is simple in structure, can avoid pressure damage and is high in wearing comfort.
