Assistant breathing device for mask wearing condition

Abstract

The invention discloses an assistant breathing device for the mask wearing condition. The assistant breathing device comprises a support frame, an output air pipe, an air delivery pipe and an air blower, wherein the two ends of the support frame are each provided with a binding hole for mounting an elastic band, the lower end of the support frame is provided with two support frame lifting lugs, and the support frame lifting lugs are used for mounting and fixing the output air pipe; one end of the output air pipe is closed, the other end of the output air pipe is connected with the air deliverypipe, and the output air pipe is upwards provided with air delivery ports; the air delivery pipe is connected with an output port of the air blower, a suction inlet of the air blower is provided witha filter screen, and a motor of the air blower is connected with a power plug through a wire. According to the assistant breathing device, filtered and qualified fresh air is conveyed into the part near the nostrils through the pipe, foul air remaining in a cavity formed between the face of a human body and a mask is blown away at the time of reducing the breathing resistance to prevent the foulair from being sucked into the body, the breathing efficiency is improved, and the adverse effects such as oxygen deficiency and chest distress caused by wearing the masks on people is relieved or eliminated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary breathing device for wearing a mask. Background technique [0002] In operating rooms, infectious diseases departments of hospitals, or public places during epidemics, in order to prevent cross-infection, medical staff or the general public must wear protective masks, especially medical masks or N95 without exhalation valves, etc. A mask with a higher level of protection. When wearing these masks, in addition to the large breathing resistance, a small amount of turbid air exhaled by the human body will remain in the cavity formed between the face and the mask. When inhaling, this part of turbid air will be re-inhaled into the body, which will affect the breathing efficiency. . When wearing these masks for a long time, due to the reasons that affect the breathing efficiency such as large breathing resistance, it will give people the feeling of hypoxia and ch...

Problems solved by technology

When wearing these masks, in addition to the large breathing resistance, a small amount of turbid air exhaled by the human body will remain in the cavity formed between the face and the mask. When inhaling, this part of turbid air will be re-inhaled into the body, which will affect the breathing efficiency.

When wearing these masks for a long time, due to reasons such as high respiratory resistance that affect breathing efficiency, people will feel hypoxia and chest tightness, which will affect people's work efficiency and physical health to a certain extent.
