Double-layer composite positive pressure medical protective clothing

Abstract

The invention discloses a double-layer composite positive pressure medical protective garment which is composed of a transparent window hood, an upper garment, trousers, an air purification fan, a fan air delivery pipe, an air delivery base, a voice and video transmitter, a net-shaped pocket, a front bonding face and side bonding faces. Coated fabrics are used as protective layers of the jacket and trousers of the protective clothing, non-coated fabrics are used as lining layers of the jacket and the trousers of the protective clothing, the two layers of fabrics are locally compounded, and non-compounded areas are communicated with each other to form an air transmission space; a matched air purification fan conveys purified air into the air conveying space of the protective suit, the purified air is evacuated and conveyed into the near space in the protective suit through micro gaps among fibers of the lining layer, and then mixed air containing carbon dioxide, heat and sweat steam is exhausted through a one-way exhaust valve at the top of the head cover. According to the utility model, the defects of poor heat dissipation, mask tightening pain and the like when medical personnel wear disposable protective clothing are eliminated, the problems of inconvenient voice communication, visual identification and carrying are successfully solved, and the disposable protective clothing can be repeatedly used after being specially cleaned and disinfected after being used.

Description

technical field [0001] The invention belongs to the technical field of protective clothing, in particular relates to three-level positive pressure medical protective clothing, which can also be used for health protection of general population in special environments such as epidemic areas, sandstorms, smog, dust, etc., or immunity for daily commuting of susceptible populations. protection. Background technique [0002] Level 3 medical protection requires medical staff to wear protective clothing that is strictly waterproof, anti-blood, anti-droplets, anti-body fluids, and effectively isolates bacteria, viruses, dust, etc. in the ward environment, especially in response to SARS, COVID-19, Severe viruses such as Ebola, influenza A, AIDS, and plague require medical staff to wear level-three medical protective clothing with high protection requirements.

Problems solved by technology

[0002] Level 3 medical protection requires medical staff to wear protective clothing that is strictly waterproof, anti-blood, anti-droplets, anti-body fluids, and effectively isolates bacteria, viruses, dust, etc. in the ward environment, especially in response to SARS, COVID-19, Severe viruses such as Ebola, influenza A, AIDS, and plague require medical staff to wear level-three medical protective clothing with high protection requirements. However, the level-three medical protective clothing widely used now is generally non-positive pressure disposable protective clothing. Unable to prevent occupational exposure

[0003] 1. It cannot effectively dissipate heat, causing medical staff to be hot and sweaty, and feel bad;

[0004] 2. The mask straps are strangling the cheeks and the bridge of the nose for a long time and with high intensity, causing the medical staff's facial skin to be blood stasis, edema, deep purple indentation, allergies and inflammation, even broken skin and bleeding, which is unbearable pain;

[0005] 3. Protective masks and goggles are easy to gather water mist, and even condense into water droplets, causing obvious visual impairment to medical staff;

[0006] 4. If you wear it for a long time, especially in a high temperature environ
