Abstract

The invention discloses a mouth-nose mask which comprises a mask body capable of covering the mouth part and the nose part. The mask body is provided with a breathing hole for air to enter and exit, the peripheral edge of the mask body is provided with a sealing bag body used for making direct or indirect contact with the face of a human body, a cavity is formed in the sealing bag body, and the mask body is connected with the sealing bag body. A sealing bag body is arranged on a mask body, the sealing bag body is not fully filled with gas and / or liquid, when the mask body is used, the gap between the mask body and the face is filled with gas and / or liquid in the sealing bag, and certain pressure is kept. The fluidity of gas and / or liquid in the sealing bag body is utilized, so that the sealing bag body can bulge at the concave part of the face of a human body under the action of small external force, the protrusions on the face of the human body can be shrunken, the mask can be fully attached to the face of the human body, and therefore the gap between the gas face and the mask body is completely eradicated, the mask can be in the same specification, and production and replacementare convenient.

Description

technical field [0001] The invention relates to the technical field of medical equipment and labor protection articles, in particular to an oral and nasal mask. Background technique [0002] Many masks are used in medical treatment, some are anti-virus and some are anti-dust. However, the current masks do not fit the human face tightly enough, so that dust and viruses enter the respiratory tract and cause the masks to lose their proper functions. For now, this problem has been noticed and some measures have been taken. For example, the mask is equipped with an iron clip on the bridge of the nose. When wearing the mask, pinch the iron clip so that it fits the bridge of the nose, but the iron clip will loosen , Fatigue, the method of using iron clamps 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 match the micron level of the filter ability of the mask...
