Description

Composite mask

Technical Field

The invention relates to the technical field of medical equipment and common civil sanitary protection products, in particular to a composite mask.

Background

The mask has the function of blocking particulate matters and microorganisms in the air from entering human respiratory tract through nostrils or oral cavity, is basically disposable, and is especially popular with new viruses such as new crowns in recent years, and is very popular in wearing the mask, thus being an effective individual protection important measure. Meanwhile, the mask is also a tool for preventing people or patients with viruses from removing viruses, polluted air and surrounding healthy people. However, during use of the mask, the following disadvantages exist:

1. because the nose bridge protrudes out of the cheek portion, the cheek portion is uneven, the mask forms groove gaps on two sides of the high-rise nose bridge, and the upper portion of the mask is tightly attached to the skin by the hanging strips, so that the mask is not naturally and tightly attached, exhaled air easily overflows from the groove gaps to the upper portion of the mask, air leakage occurs, and a wearer wearing eyes easily generates lens fog. Even if a shapable metal splint is used at the nose bridge part of the mask, the groove gap is eliminated, so that the upper part of the mask is better attached to the cheek part, but the gap can be eliminated only by tightening a hanging strap, otherwise, if the hanging strap is not tightened sufficiently, fog can still be generated due to air leakage;

2. when the mask hanging strip or the ear hook is too tightly collected, the hard mask or the nose metal clip is tightly attached to the cheek skin for too long, so that the cheek skin is easy to be crushed;

3. after the wearer pollutes the mask due to nasal discharge, sneeze, cough and the like, the mask is removed and the mask is worn again, and the mask is inconvenient to replace for a plurality of times for certain people, such as long-distance drivers and operators in dangerous industries, and the mask is inconvenient and safe to replace.

Therefore, there is a need for a method of quickly and conveniently replacing a mask and a mask that does not generate lens fog. The silicone gel cushion is arranged around the patent with publication number of CN212488597U, so that the problems of skin redness and cyanosis of the face after the mask is worn for a long time can be effectively prevented, the pressure can be dispersed, the occurrence of pressure sores and nerve injury are reduced, the tightness of the joint and the comfort of medical staff wearing the mask are increased, the earhook or hanging strip is still required to be fixed, and the mask can not be used repeatedly.
