Original title: What materials are medical protective suit made of? Types of medical protective suit. At present, in addition to head, hand and foot protective products, there are mainly three kinds of trunk protective products used in hospitals: isolation clothing, surgical gowns and medical protective suit. Isolation clothing refers to the clothing worn by medical staff in contact with patients, family visits to patients and other occasions; The term "surgical gown" refers to a specially designed garment worn in the operating room; Protective suit refers to the clothing worn by personnel entering special areas such as medical first aid, infectious disease areas and electromagnetic radiation areas. According to the requirements of different use conditions, the three products should meet different performance requirements. Among them, isolation clothing is the first class of medical devices, with the lowest performance requirements. At present, there is no industry standard or national standard in China. Surgical gowns and protective suit are the second class of medical equipment. Our country has established the performance research method of surgical gowns in YY/T 0506 series standards, and the technical requirements of medical disposable protective suit in GB 19082. At present, the standard of reusable medical protective suit has not been established in China. Here we mainly introduce the medical disposable protective suit that meet the requirements listed in the GB 19082, which is also the most needed protective suit in this epidemic. The product is mainly used for medical staff who may contact with potentially infectious patients' blood, body fluids, secretions and airborne particles during work. Material of medical protective suit. Protective suit are typically made from composite materials such as polyester or polypropylene spunlaid nonwovens with breathable microporous films or other nonwovens, or spunlaced nonwovens with breathable microporous films, or wood pulp composite spunlaced nonwoven. At present, polyethylene flash-spun nonwovens and spunbonded/meltblown/spunbonded (SMS) or spunbonded/meltblown/melt-blown/spunbound (SMMS) composite nonwovens are widely used to be compounded with microporous films, and are subjected to functional finishing of "three repellencies and one resistance" (water repellency, blood repellency, alcohol repellency and antistatic property). Nonwovens: Refers to a sheet, web, or batt made of oriented or randomly arranged fibers that are bonded to each other by friction, cohesion, or bonding, or a combination of these methods, excluding paper, woven fabrics, knitted fabrics, tufted fabrics, and wet-felted felts (GB/T 57091997 "Terminology of Textiles and Nonwovens"). To put it simply, it is not interwoven and knitted together one by one, but the fibers are directly bonded together by physical methods, so the non-woven fabric can not pull out a thread. Performance of medical protective suit. Performance requirements for protective suit materials, including protection, serviceability, safety and hygiene. Simply put, protective suit should not only be moisture-proof and breathable, but also protect medical staff from viruses, bacteria and other pollutants in the process of diagnosis and treatment, resist the invasion of water, alcohol and blood, and effectively resist static electricity and even prevent dust from entering. Specifically: ① The protective requirements shall have the function of liquid barrier, the key parts of the protective suit (left and right front, left and right arms and back) shall have water permeability resistance, and the hydrostatic pressure resistance shall not be less than 1.67 kPa; the synthetic blood penetration resistance shall not be less than Grade 2, that is, the synthetic blood shall not penetrate after acting on the protective suit for 5 minutes under the pressure of 1.75 kPa; the water level of the outer side of the protective suit shall not be lower than Grade 3. This technical index is to prevent the patient's blood, or the disinfection water, washing liquid and other liquids during the operation from penetrating the protective suit and polluting the medical workers. Expand the full text ② The protective suit shall have the performance of preventing the penetration of micro-particles, and the filtration efficiency of the key parts and joints of the protective suit for non-oily particles shall not be less than 70%. This technical target is to prevent the invasion of virus-carrying particles (such as spit, etc.). In addition, the seams of protective suit must be sealed to cover the needle holes left by sewing. ③ The serviceability requirements of protective suit include sufficient strength and dimensional stability. During the tensile test, the breaking strength shall not be less than 45 N and the elongation at break shall not be less than 30%. This technical index is to ensure the physical properties of clothing, so that it is not easy to damage.
(4) In terms of wearing comfort of protective suit, the moisture permeability of protective suit materials should not be less than 2500 G/m2 · d. This technical index is to ensure that the sweaty heat of the wearer is discharged in time. ⑤ The safety and hygiene of protective suit require that it is non-toxic, non-irritating to the skin and resistant to the growth of fungi. ⑥ The protective suit is disposable, so it is required to reduce the cost as much as possible while ensuring the protective performance in terms of economy. Medical protective suit related standards, regulations and documents We have collected medical protective suit relevant standards, regulatory requirements, documents and data requirements.

The factory inspection items shall at least include the following items: appearance, structure and size, breaking strength, elongation at break, microbial indicators, and ethylene oxide residue (if ethylene oxide sterilization is used). Considering the incoming inspection of raw materials and the outgoing inspection of medical protective suit, enterprises should configure basic inspection instruments, such as dynamometer, micrometer, vernier caliper, ruler, etc. If the microbiological indicators and ethylene oxide residues are self-tested, a microbiological laboratory and corresponding instruments are required. The type inspection shall be the full performance inspection of the product technical requirements, and the medical device inspection Institute approved by the Food and Drug Administration shall be selected. The General Administration of Market Supervision has published a list of state-level qualified inspection and testing institutions for medical devices and protective articles. The General Administration of Market Supervision (CNCA) announces the list of inspection and testing institutions of medical devices and protective articles with national qualifications. Time: 2020-02-07 Source: Website of the General Administration of Market Supervision In order to strengthen the quality and safety supervision of protective articles, give full play to the technical support role of inspection and testing in epidemic prevention and control, and meet the needs of inspection and testing of protective articles, the inspection and testing institutions of medical devices protective articles that have obtained qualification certification through the approval of the National Certification and Accreditation Regulatory Commission are now published in a centralized manner (the specific list is attached).
There are 55 such institutions, of which 30 have the ability to detect medical disposable protective suit, 34 have the ability to detect medical protective masks, 28 have the capability to detect surgical mask, 24 have the capability to detect disposable medical masks, 34 have the capabilit y to detect disposable sterilized rubber surgical gloves, and all of them are equipped with medical protective masks. 34 companies have the ability to detect disposable medical rubber inspection gloves. In addition, there are more than 170 inspection and testing institutions for protective equipment that have been certified by provincial market supervision departments, and units or individuals in need can consult local market supervision departments or relevant inspection and testing institutions. Epidemic is the order, and prevention and control is the responsibility. Relevant inspection and testing institutions should conscientiously implement the major decisions and arrangements of the CPC Central Committee and the State Council on the prevention and control of the new coronavirus pneumonia epidemic, stick to their posts, open a green channel for the inspection and testing of protective articles, do a good job in the inspection and testing of protective articles during the epidemic prevention and control period, and provide accurate, fast and high-quality technical support services for consumers and users.
