Pressurized drying protective clothing

Abstract

The invention relates to the technical field of protective clothing, in particular to pressurized drying protective clothing. An eyepiece and a protective clothing body are integrally connected and cannot be detached. Hydrophobic poly-p-xylylene (parylene) coatings are arranged on the inner sides of the eyepiece and the protective clothing body, so that the eyepiece can be kept clear, no water vapor is attached to the interior of the protective clothing, and the comfort of medical personnel wearing the protective clothing for a long time is further improved. Through the arrangement of a dryingand disinfecting bottle, a direct-current fan, a 100-level high-pressure clean air bottle, an air inlet hose system, an air exhaust hose system and a pressurizing hose system, the positive-pressure environment in the protective clothing and drying and non-toxicity of circulating air can be achieved, and the safety and comfort in the protective clothing are improved. A breathing filtering device and a crotch opening can be opened, pressurization is conducted in combination with the 100-level high-pressure clean air bottle, pressurized air can flow towards the outside of the protective clothingin a one-way mode through the opening, the necessary eating and defecation requirements of medical staff during work are met, and the single-time use time of a single piece of protective clothing isprolonged.

Description

technical field [0001] The invention relates to the technical field of protective clothing, in particular to a pressure-drying protective clothing. Background technique [0002] The new type of coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) has infected nearly 80,000 people around the world since December 2019. According to health and epidemic prevention experts, the main routes of transmission of the new type of coronavirus pneumonia are direct transmission, aerosol transmission and Contact spread. Direct transmission refers to the infection caused by close-range direct inhalation of droplets from patients’ sneezing, coughing, talking and exhaled gas; aerosol transmission refers to the mixing of droplets in the air to form aerosols, which lead to infection after inhalation; contact transmission refers to The droplets are deposited on the surface of the article, and after touching the contaminated hands, they touch the mucous membranes of the mouth, nose and ey...

Problems solved by technology

In this way, a certain positive pressure can be maintained in the protective clothing, but while the positive pressure is maintained, the humidity inside the protective clothing will continue to increase as the wearing time increases, which will not only form water mist on the mask, blocking the sight of medical staff , will also affect the comfort of wearing

[0004] Chinese patent CN 202127844 U enters the hood through the linear exhaust hole and forms an air curtain, which protects the front face screen from fogging caused by exhalation while supplying the wearer with breathing. Air will gradually affect the breathing comfort of medical staff, and the humidity inside the protective clothing will also increase with the working hours

[0005] Chinese patents CN 205093614 U and CN 104687543 A both design the protective clothing to input clean air into the head, so that the gas in the protective clothing flows from top to bottom. Prolonged wind exposure to the head can cause discomfort

[0006] Chinese patent CN 10871290 A adds an air pump at the waist of the protective clothing and a cooling and drying structure to reduce the internal temperature and humidity of the protective clothing, but cannot effectively maintain the positive pressure state inside the protective clothing
