Description

A capsule for sealing

Technical field

The invention relates to the technical field of medical equipment and labor protection articles, and in particular to a capsule for sealing.

Background technique

Many protective masks are used 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, such as setting up an iron clip on the bridge of the nose and pinching the iron clip when wearing a mask to fit the bridge of the nose, but this iron clip will become loose. Fatigue, using iron clips cannot completely prevent dust and viruses from entering the gap between the mask and the face.

In order to prevent the inhalation of the virus, some medical staff wear a four-layer mask, but the result is still infected with the virus. The reason is not that the mask is not well protected, but that the breathability of the mask is poor after wearing the four-layer mask. The air enters directly from the gap between the mask and the face, which is worse than wearing a mask at this time.

Due to the different facial shapes of the human body, such as the lower nose bridge of Eastern people and the higher nose bridge of Westerners, it is difficult to make a mask fit everyone's face completely.
