Description

A kind of N95 mask for preventing skin damage

technical field

The utility model relates to the technical field of medical supplies, in particular to an N95 mask for preventing skin damage.

Background technique

N95 respirator is one of the 9 kinds of particle protective respirators certified by NIOSH. N95 is not a specific product name. As long as it meets the N95 standard and passes the NIOSH review, it can be called an N95 respirator. The filtration efficiency of particles with a diameter of 0.075 μm ± 0.020 μm is above 95%;

N95 masks usually have three layers, the innermost layer is usually ordinary medical gauze, the middle layer is usually melt-blown cloth, and the outermost layer is usually waterproof-treated melt-blown cloth, because the outermost melt-blown cloth of the N95 mask has been waterproofed As a result, when medical staff wear N95 masks, the moisture in the exhaled gas cannot follow the gas to the outside of the mask, and the moisture regain of medical gauze is 6%-7%. Because the hygroscopicity of fibers is mainly determined by the public moisture regain of fibers Said that the higher the public moisture regain rate, the better its hygroscopicity, which will lead to medical gauze unable to continue to absorb the water exhaled by medical staff after wearing N95 for a long time, which will cause the water to stay in the N95 mask, resulting in N95 The air in the mask is relatively humid. After the medical staff wear the N95 mask for a long time, the medical staff will cause bacteria to grow due to wet skin, which will damage the skin of the medical staff. Moreover, the traditional N95 masks are usually ear-hanging, which will cause N95 masks to After wearing for a period of time, the upper edge of the ear and the back of the ear of the medical staff will be damaged due to the friction or extrusion of the elastic cord, which is not convenient for use.
