Sandwiched Three Layer Composite Material, The First National Reusable Medical Protective Clothing Was Born In Beijing.

After the outbreak of the new crown pneumonia virus, the consumption of disposable medical protective clothing is large and the production cycle is long. There has been a tight supply situation. In order to meet the clinical demand for reusable medical protective clothing and reduce the cost of medical waste treatment, Beijing has set up a scientific research project group of "reusable medical protective clothing". In April 22nd, the reporter learned from the Beijing pharmaceutical inspection bureau that the medical protective clothing produced by Beijing bond company was the two class of medical device registration certificate issued by Beijing Municipal Drug Administration, and became the first similar product approved in the country.

Measurement, tailoring, wrapping joints, sewing, mounting zippers... In the workshop of three wool spinning garden in Pinggu District, workers are producing reusable medical protective clothing. Reporters at the scene saw that the reusable medical protective clothing changed the single layer non-woven fabric covering material of the traditional disposable medical protective clothing, and made use of the "sandwich" three layer composite material.

According to Wang Xuguang, technical director of Beijing banner high tech special textiles Co., Ltd., this material meets the requirements of washing resistance, has strong physical mechanical strength and strong anti breaking ability, among which breaking strength and water penetration resistance meet the requirements of medical disposable protective clothing standard more than 10 times. The material is not only durable, but also has better drainage effect. In addition, the production process has changed the traditional one-off medical protective clothing one-off adhesive paste process, using the Velcro sealing process at the front.

"At present, the key detection indicators of this protective clothing are better than that of disposable protective clothing. The results of key performance tests of the approved reusable medical protective clothing, such as breaking strength, filtration efficiency, synthetic blood penetration and water permeability, are all higher than the national standard of disposable medical protective clothing." Wang Xuguang said that the current production of this protective clothing is 200 units per day, and it can be reused 10 times. Once every washing and disinfection, it will be marked out in the water washing standard of the protective clothing to prevent more than the number of times.

It is understood that during the prevention and control of new crown virus pneumonia, the demand for protective clothing and other medical control materials increased sharply. In order to alleviate the tense supply situation of the disposable medical protective clothing and the long production cycle, and to meet the clinical demand for reusable medical protective clothing and reduce the cost of medical waste treatment, the Beijing Municipal Drug Regulatory Bureau and the science and Technology Commission established Beijing's "heavy load". Use medical protective clothing again "scientific research project. After the project was approved, it took 68 days to mobilize the strength of universities, research institutes, medical institutions and science and technology enterprises, organized several experts' argumentation, compiled the 8 edition of the clinical trial plan, and completed nearly 60 verification of various data.
