[0002] Medical protective clothing is the protective clothing used by medical staff and people entering specific medical and health areas. Its function is to isolate germs, harmful ultrafine dust, acid-base solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean. When removing the protective clothing, it is necessary to press and wash or disinfect the protective clothing to inhibit the diffusion of toxic and harmful aerosols during removal and prevent secondary pollution of personnel and the environment.

[0003] Existing medical protective clothing is generally for single-use. Although the cost of a single piece of this protective clothing is relatively low, long-term single-use will cause waste of resources, increase the use cost, and the destruction and treatment may cause environmental pollution.
