Problems solved by technology

[0003] Ordinary medical masks have a fixed shape, and the faces of larger medical staff will be larger. When larger medical staff use ordinary medical masks, the ordinary masks cannot be adjusted according to the face shape of the medical staff, so they cannot completely protect the medical staff. On the face, germs are easy to infect medical staff through the exposed facial skin, and ordinary masks cannot adjust the air intake of medical masks according to the body shape of medical staff

Abstract

The invention relates to a medical mask, and particularly relates to a medical mask suitable for medical staffs with different body types and capable of easily adjusting air inflow. The medical mask comprises a mask shell, protective shells, a telescopic belt, belt one-way melt-blown cloth filter layers, a soft cushion supporting and adjusting assembly, clamping assemblies, an air inlet adjusting assembly and the like; and the protective shells are symmetrically arranged on the mask shell, the telescopic belt is arranged on the protective shells together, the belt one-way melt-blown cloth filter layers are symmetrically arranged on the mask shell, the soft cushion supporting and adjusting assembly is arranged on the mask shell, the clamping assemblies are arranged on the protective shells, and the air inlet adjusting assembly is arranged on the mask shell. Through the indication assembly, the number, corresponding to the scale bar, of the indication rod can change along with the change of the movement distance of the manual pushing bar so that a medical staff can conveniently judge whether the cushion body moves to a proper distance in the direction close to the telescopic belt or not according to the number, corresponding to the scale bar, of the indication rod; and the effect of judging whether the medical mask is adjusted to be matched with the body shape of the medical staff or not is achieved.

Description

technical field [0001] The invention relates to a medical mask, in particular to a medical mask which is suitable for medical staff of different sizes and is easy to adjust the amount of air intake. Background technique [0002] Medical masks are better protective equipment. It is recommended to wear them when there is severe environmental pollution or sudden medical infectious diseases (such as respiratory infectious diseases) to prevent the spread of viruses from patients or the environment to users. The masks used by medical personnel are medical masks, so the performance requirements for medical masks will be higher than those of ordinary masks. [0003] Ordinary medical masks have a fixed shape, and the faces of larger medical staff will be larger. When larger medical staff use ordinary medical masks, the ordinary masks cannot be adjusted according to the face shape of the medical staff, so they cannot completely protect the medical staff. Germs can easily infect medic...
