Description

A kind of multifunctional medical protective mask

Technical field

The utility model relates to a kind of mouth mask, but but the multifunctional protection mouth mask of especially a kind of not only bacteriological protection, virus but also smoke and dust proof.

Background technology

The mouth mask of relevant anti-communicable disease is less both at home and abroad at present, and 16 layers of cotton cloth respirator are overweight, and the side leakage of mouth mask periphery is bigger, and the anti-particle diameter＜virom crosome of 1 μ m and big slightly anthracia bacterium particulate effect are relatively poor, and dustproof Smoke prevention effect also owes desirable; The efficient anti-dust respirator of minority can anti-virus, but sterilization, cleans difficulty, the complex structure heaviness, and inconvenience is worn, and costs an arm and a leg.

The utility model content

The purpose of this utility model is to provide that a kind of structure is light and handy, protection efficiency is high, cleans easily, and is cheap, but both anti-communicable diseases, the multifunctional medical protective mask of the Smoke prevention of can preventing dust again.

The utility model comprises gauze layer, mouth mask bound edge, headband, it is characterized in that, also is provided with the filter material layer of anti-virus, germ and preventing dust, and filter material layer places between the inside and outside two-layer gauze, and the also available nonwoven of gauze replaces.Filtrate is preferably selected modification lower resistance filtrate for use; Gauze (do not have anti-cloth), filter material layer place periphery can be close on the support of the approximate bowl-type of face around the mouth and nose, and support should or have the material of similar performance to make with flexible plastic; The support periphery should be with sponge or foam plastics strip parcel, to improve comfortable wearing.Mouth mask the right and left also should be provided with the filtrate washer, in case the mouth mask side gas leakage of when speech, also can indicate after sterilization cleans, and whether the filter material layer of two-layer gauze protection damages.Headband preferably adopts elastic cord.

The utility model is side leakage free almost; Structure is light and handy; Comfortable wearing; Resistance is very little; Cost is lower; Virom crosome efficient such as bacteriological protection, influenza and SARS can reach 96%, and dustproof efficient can reach 99%, and total penetrating leaking coefficient is 3-6% only, respiratory resistance 1.5mmH ₂O, the about 140cm of dead space ³, hinder the visual field, below 5 degree.Wear this kind mouth mask, can prevent viruses such as anthracia bacterium, influenza, SARS and lead fume, mist of oil, sodium cigarette.
