In the "Wuhan Epidemic Prevention War", disposable medical protective shoe covers are also one of the strategic materials in short supply. Although the report shows that the new coronavirus is a droplet and contact infection, there are still cases of infection caused by medical staff on the front line because they did not wear shoe covers. "The disease enters from the feet" has also become a suspected method of virus infection. The highly contagious nature of the new coronavirus has forced us to pay attention to the quality of disposable medical protective shoe covers. Although YY/T 1633-2019 "Disposable Medical Protective Shoe Covers" has not yet been officially implemented (implemented on May 1). However, as a professional protective equipment testing agency, Byrne Testing organized and learned relevant regulations for the first time, and I would like to share with you here.

Specification and structure inspection
According to the regulations in YY/T 1633-2019, disposable medical protective shoe covers are mainly used to protect the legs and feet of medical, epidemic prevention, and disease control personnel from potentially infectious pollutants (blood, body fluids, etc.). , Secretions, excrement, vomit, etc.) hazard protective boot covers. The specification and structural design diagram of disposable medical protective shoe covers are as follows:

In addition to reasonable structure and convenient putting on and taking off, disposable medical protective shoe covers should also be designed in a closed form, such as elastic closing, drawstring closing, and strap closing. In addition, in terms of appearance, the shoe cover should have no obvious defects, and the connecting part should be smooth and tight.

Performance test
The performance testing items related to disposable medical protective shoe covers mainly require testing of water seepage resistance, resistance to synthetic blood penetration, surface moisture resistance, breaking strength, elongation at break, filtration efficiency, microbial indicators, and residual ethylene oxide . Among them, the microbiological indicators mainly require the detection of the total number of bacterial colonies, coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus hemolyticus, and the total number of fungal colonies.

When we actually produce disposable medical protective shoe covers, according to the testing data, we have good isolation performance, good waterproof effect, good wear resistance, excellent corrosion resistance, tear resistance, peeling resistance, and good ventilation performance. , It can completely cover the parts such as the socks and trousers of medical wearers, easy to put on and take off. Protective shoe covers that pass these indicators are more popular.
