During the prevention and control of the COVID-19 epidemic, the demand for medical prevention and control materials surged. Beijing has set up a research project on “reusable medical protective clothing”. At present, the country’s first reusable medical protective clothing has been approved for listing in Beijing. It can be reused about 10 times after washing and disinfecting.
It can produce 5000 pieces per month and will soon be put into the front line of epidemic prevention
This morning (April 22), in the Mafang Industrial Park in Pinggu District, Beijing, pieces of reusable medical protective clothing were being produced from the assembly line. These protective clothing were developed and produced by a company in Beijing. Recently, they received the second-class medical device registration certificate issued by the Beijing Municipal Food and Drug Administration, becoming the first product of its kind approved for listing in the country, and will soon be put on the front line of epidemic prevention.
At present, the production capacity of the company’s reusable medical protective clothing can reach 5,000 pieces per month.
Compared with the disposable protective clothing that needs to be discarded after a few hours of use, these protective clothing can be reused and can withstand about 10 times of medical treatment. Washing and disinfection saves one-third of the overall cost.
It is understood that after the COVID-19 outbreak, the Beijing Municipal Drug Administration, the Science and Technology Commission and other departments established a “reusable scientific research on medical protective clothing research” project team, and urgently launched an epidemic prevention and control emergency science and technology special research, which lasted 68 days. To combat the major needs of the COVID-19 epidemic, extensively mobilize the superior strength of Beijing universities, research institutes, medical institutions, and technology companies, work closely together, and accelerate research, organize multiple expert demonstrations, compile 8 versions of clinical trial programs, and complete various data Verify more than 60 items. On April 17, the reusable medical protective clothing produced by Beijing Bangwei Company was awarded the second-class medical device registration certificate issued by the Beijing Municipal Drug Administration, becoming the first product of its kind approved for listing in the country.
In order to allow reusable protective clothing to be put into use as soon as possible, after the project is approved, the Beijing Municipal Food and Drug Administration will follow the principles of “unified command, early intervention, follow-up and follow-up, and scientific approval” on the premise that standards and procedures are not reduced At the first time, the registration inspection, on-site inspection and technical review work were completed. At present, the product has completed all registration procedures in accordance with national regulations.
Key testing indicators are better than medical disposable protective clothing
Wang Fuyi, deputy director of the Beijing Municipal Drug Administration, said that after testing, the critical performance test results of the approved reusable medical protective clothing such as breaking strength, filtration efficiency, anti-synthetic blood penetration, and anti-water permeability are higher than medical National standard for disposable protective clothing.
The reporter learned from the manufacturer that these two types of protective clothing differ in terms of material composition, production process, clothing structure, etc., which can meet the requirements of repeated use. In terms of material composition, the single-layer non-woven fabric coating material of the traditional disposable medical protective clothing is changed, and the three-layer composite material independently developed by the company is used to meet the requirements of washing resistance, strong physical and mechanical strength, and resistance to damage Strong ability, among which the breaking strength and water permeability resistance requirements are more than 10 times the standard of medical disposable protective clothing.
The production process of the new reusable protective clothing is also very different from the traditional disposable protective clothing. The reporter saw in the production workshop that a pile of raw materials were processed layer by layer and turned into reusable protective clothing. The person in charge of the company told reporters that the new reusable protective clothing changed the disposable adhesive sticker process of the traditional disposable medical protective clothing. The Velcro sealing process at the placket was adopted to ensure that it can still be achieved after repeated cleaning. Sealing effect.
The reporter saw in the workshop that the reusable protective clothing changed the outer sticking structure of the traditional disposable medical protective clothing. The inner pressure strip, airtight zipper, double cuffs and double trousers were designed to improve the overall protection of the product. Sex. In the clothes, a special mark for the number of washing times has been added to track the usage of the product. According to the current test situation, each protective clothing can withstand about 10 times of medical washing and disinfection.
