Medical mask

Abstract

The invention discloses a medical mask. The medical mask comprises a mask body and tying lines arranged on the two sides of the mask body, wherein the tying lines can extend to the rear side of the head, a bamboo charcoal adsorption layer and at least two fiber filtering layers are arranged in the middle of the mask body, rough selvedges which can prevent dust from entering the mask are arranged on the edges of the mask body, and an extension area is arranged on the middle upper portion of the mask body. The medical mask is simple in structure, the tying lines can be fixed to the ears and can be tied to the rear side of the head as well, the tightness degree can vary with each individual, the bamboo charcoal adsorption layer and the fiber filtering layers are arranged in the middle of the mask body so that dust can be adsorbed and filtered out, the rough selvedges are arranged on the edges of the mask so that dust can be prevented from entering the mask through the mask edges, dust can be temporarily adsorbed to the rough selvedges, the extension area is arranged on the middle upper portion of the mask body to make inhaled air fresh and wet due to the fact that the noise is located on the middle upper portion of the mask body, the bamboo charcoal adsorption layer and a moisture preservation layer are arranged on the extension area so that the inhaled air can pass through the extension area, dust in the air can be filtered out, and the moisture preservation effect can be achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical mask. Background technique [0002] In hospitals, medical personnel usually wear masks. The existing medical masks have relatively simple structures, and most of them are made of cotton fiber materials. Lanyards that are placed on the ears are usually provided on both sides of the mask body. , because the shape of the human face cannot be exactly the same, so the length of the lanyard of the mask cannot be just right. If it is too tight, it will hurt the ears. If it is too loose, the mask will easily slip off, and there will inevitably be gaps on the edge of the mask. Dust easily penetrates through the gaps and enters the inside of the mask. Therefore, after using the mask for a certain period of time, it will be found that more dust will accumulate on the edge of the mask, which will affect the quality of the air the user breathes.
