Description

Novel face mask

Technical Field

The utility model relates to the technical field of medical equipment and labor protection articles, in particular to a novel face mask.

Background

A plurality of masks are available in medical treatment, some masks are anti-virus and some masks are dustproof, but the existing masks are not tightly attached to the face of a human body, so that dust and viruses enter respiratory tracts to cause the masks to lose due functions. At present, the problem has been noticed, and some measures have been taken, such as the mask is provided with an iron clip at the nose bridge, and the iron clip is pinched when the mask is worn to fit the nose bridge, but the iron clip will loosen and fatigue, and the iron clip cannot completely prevent dust and virus from entering from the gap between the mask and the face. The iron clip obviously cannot enable the gap between the mask and the face to be in a micron scale matched with the filtering capacity of the mask. For example, in china, some medical staff wear a four-layer mask to prevent virus inhalation, but the mask still becomes infected with virus as a result, and the reason for this is that the mask is not well protected, but after wearing the four-layer mask, the ventilation capacity of the mask is poor, so that air directly enters from the gap between the mask and the face, which is worse than the effect of wearing a one-layer mask. Because the gauze mask is mostly disposable, only use two to three hours, and the gauze mask will make the finished product process many, will put the metal strip, will put rope or elastic cord etc. and produce complicatedly.

In addition, the air permeability of the current N95 mask is poor, so that a user feels difficulty in breathing, and many people do not want to wear the mask. An adult breathes about 0.6 liter of air once, but the area in front of the mouth, namely dozens of twenty square centimeters, needs to make the air enter and exit in a short time in the small area, which is certainly not feasible, so the area of the air entering and exiting place needs to be increased. Because the shapes of human faces are different, the nose bridge of eastern people is lower, and the nose bridge of western people is higher, so that the mask is difficult to completely fit with the faces of everyone. Therefore, it is necessary to design a new mask for the problem of the mask.
