Description

A new type of mask

Technical field

The invention relates to the technical field of medical equipment and labor protection products, in particular to a new type of face mask.

Background technique

Many masks are useful in medical treatment, some are anti-virus and some are dust-proof, but the current masks are not closely attached to the human face, so that dust and viruses enter the respiratory tract and cause the mask to lose its proper function. For now, this problem has been noticed and some measures have been taken. For example, the mask has an iron clip on the bridge of the nose. When wearing the mask, pinch the iron clip to fit the bridge of the nose, but the iron clip will loosen. , Fatigue, using iron clips cannot completely prevent dust and viruses from entering the gap between the mask and the face. Obviously, this iron clip cannot make the gap between the mask and the face a micron level that matches the filtering capacity of the mask. For example, in China, some medical staff wear a four-layer mask to prevent the inhalation of the virus, but the result is still infected with the virus. The reason is not that the mask is not well protected, but the breathability of the mask after wearing the four-layer mask. It is worse, so the air enters directly from the gap between the mask and the face, which is worse than wearing a layer of mask. Because masks are mostly disposable products, they only last for two to three hours, and there are many processes to make masks, metal strips, ropes or elastic bands, etc., and the production is complicated.

At present, the breathability of N95 masks is poor, so that users feel that it is difficult to breathe, and many people do not want to wear them. The volume of air that an adult breathes at a time is about 0.6 liters, and the area in front of the mouth is about ten or twenty square centimeters.
