Closed mask capable of preventing pressure injuries on face and behind ears

Abstract

The invention discloses a closed mask capable of preventing pressure injuries on the face and behind the ears. The mask comprises a mask body, the mask body is divided into a plurality of layers. Theupper side of the mask body is connected with an upper tying belt. The lower side of the mask body is connected with a lower tying belt; a nose wing shaping strip is fixed at the upper part of the mask body, a pressure-reducing double-sided sticker is fixed on the outer side of the nose wing shaping strip, the pressure-reducing double-sided sticker is attached to the nose wing and the face of a human body, an anti-skid structure is arranged on the upper tying belt, the anti-skid structure is in contact with the head of the human body, and the lower tying belt is sleeved on the neck of the human body. The leakproofness of the mask is guaranteed by arranging the pressure-reducing double-faced adhesive tape, the pressure on the face and behind the ears is reduced by arranging the anti-skid structure, and the problems that in clinic, a protective mask fixing band is prone to slipping off under tight protection, and consequently airtightness is poor and the pressure on the ears and the noseis damaged are solved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an airtight mask for preventing pressure injuries on the face and behind the ears. Background technique [0002] Masks are respiratory protective equipment for preventing and controlling the spread of respiratory infectious diseases. The important indicators for evaluating the protective effect of masks are the filtration efficiency of particulate matter and the degree of closeness between the mask and the wearer's face. High-risk places and personnel need to wear medical protective masks or N95 medical protective masks, or even higher-level protective equipment, when implementing close-range treatment operations that may generate aerosols for suspected or confirmed cases of new coronavirus pneumonia. During the whole wearing process, it is necessary to ensure that the airtightness is good, and the fixing method of N95 and other protective masks currently on the market ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an airtight mask for preventing pressure damage on the face and behind the ears. The airtightness of the mask can be ensured by setting decompression double-sided stickers, and the pressure on the face and behind the ears can be reduced by setting an anti-skid structure, so as to solve the problem of strict protection in clinical practice. The fixing strap of the lower protective mask is easy to slip off, resulting in poor air tightness and pressure injuries to the ears and nose
