Original Title: medical protective suit Procurement Guide Medical protective suit refers to the protective clothing used by medical staff (doctors, nurses, public health personnel, cleaning personnel, etc.) And people entering specific medical and health areas (such as patients, hospital visitors, people entering infected areas, etc.). Its function is to isolate germs, harmful superfine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean. Classification of medical protective suit. ① It can be divided into daily work clothes, surgical gowns, isolation gowns and protective suit according to the purpose and use occasion. ② According to the service life, the medical protective suit can be divided into disposable protective suit and reusable protective suit. ③ According to the different processing technology of materials, medical protective suit can be divided into woven and non-woven protective suit. Material for making medical protective suit. ① Polypropylene spunbonded fabric The polypropylene spun-bonded cloth can be made into antibacterial protective suit, antistatic protective suit and the like by antibacterial, antistatic and other treatments. Compared with the traditional protective suit of cotton cloth, the protective suit of polypropylene spunbonded cloth is undoubtedly a great progress. Because of its low price and disposable use, it can greatly reduce the cross-infection rate, and has been widely promoted abroad for a long time. However, the hydrostatic pressure resistance of the material is relatively low, and the efficiency of blocking virus particles is relatively poor, so it can only be used as sterile surgical gowns,Antivirus Disposable Mask with CE Certificate, disinfection cloth and other common protective equipment. (2) spunlaced cloth compounded by polyester fiber and wood pulp The material has soft hand feeling, is close to the traditional textile, can be subjected to three-resistance (alcohol resistance, blood resistance and oil resistance), antistatic, antibacterial and other treatments, can be disinfected by gamma rays, and is a better medical protective suit material. However, its resistance to hydrostatic pressure is relatively low, and its barrier efficiency to virus particles is relatively poor,Full Body Disposable Coverall, so it is not an ideal protective suit material. (3) polypropylene spunbond-meltblown-spunbond composite nonwoven fabric, namely SMS or SMMS Melt-blown fabrics are characterized by fine fiber diameter, large specific surface area, fluffy, soft, good drapability, small filter resistance, high filter efficiency and strong ability to resist hydrostatic pressure, but their low strength and wear resistance limit the development of their application fields to a considerable extent. However, the spunbonded fabric has a higher fiber linear density, and the fiber web is composed of continuous filaments, so its breaking strength and elongation are much larger than those of melt-blown fabric, which can make up for the shortcomings of melt-blown fabric. The material has the characteristics of uniform and beautiful appearance, high hydrostatic pressure resistance, soft hand feeling, good air permeability, good filtering effect, Medical Disposable Coverall ,Medical Full Body Coverall, strong acid and alkali resistance and the like. In addition, SMS nonwovens can also be treated with three resistances (alcohol resistance, blood resistance and oil resistance), antistatic, antibacterial and anti-aging to meet the needs of different uses. ④ High polymer coated fabric There are many kinds of coatings for protective fabrics, such as polyvinyl chloride, polyethylene, polychloroprene rubber and other synthetic rubbers. This kind of protective suit has very good waterproof and bacterial particle barrier properties and can be reused, but its moisture permeability is poor, a large amount of human sweat can not be discharged, and its wearing comfort is poor. The protective suit of using rubber-coated fabrics in Severe Acute Respiratory Syndrome (SARS) period is really a last resort. Expand the full text The latest development at home and abroad is to use microporous PTFE film and fabric to obtain waterproof and breathable function, but it is expensive as a disposable product. (5) polyethylene breathable film/nonwoven composite cloth According to the different requirements of protection grade, the nonwovens and films used are also different. The polyethylene breathable film/non-woven fabric composite material has an excellent effect of obstructing penetration of bacterial particles and liquid, the hand feeling can be adjusted by changing the softness of the composite fabric, the tensile strength is strong, the breathability is good, the comfort performance is greatly improved, the composite fabric can undergo disinfection treatment, does not contain toxic components, has a gram weight of 60-100g/m2, and has good cost performance. The medical disposable protective suit made of it can protect the medical staff from being polluted by pollution sources, overcome cross infection and play an effective role in protection. Performance requirements for medical protective suit. A. Protection: Protection is the most important performance requirement of medical protective suit, which mainly includes liquid barrier, microbial barrier and particulate barrier. Liquid barrier: medical protective suit should be able to prevent the penetration of water, blood, alcohol and other liquids, with more than 4 levels of hydrophobicity, so as not to stain clothes and human body. Prevent the patient’s blood, body fluids and other secretions from transmitting the virus to the medical staff during the operation. Microbial barrier: Includes barriers to bacteria and viruses. The barrier to bacteria is mainly to prevent contact transmission (and reverse transmission) from medical staff to the patient’s surgical wound during the operation. The barrier to viruses is mainly to prevent medical staff from contacting patients’blood and body fluids, which carry viruses causing cross infection between doctors and patients. Particulate matter barrier: prevents airborne viruses from being inhaled in the form of aerosols or attached to the skin surface and absorbed by the human body. B. Comfort: Comfort includes breathability, water vapor penetration, drape, mass, surface thickness, electrostatic properties, color, light reflection, odor, and skin sensitization. In order to enhance the protective effect, protective suit fabrics are usually laminated or laminated, resulting in heavy and poor air permeability and moisture permeability, which is not conducive to perspiration and heat discharge for long-term wear. Antistatic requirements are to prevent static electricity in the operating room from causing the surgical gown to absorb a large amount of dust and bacteria, which is harmful to the patient’s wound, and to prevent the sparks generated by static electricity from detonating volatile gases in the operating room and affecting the accuracy of precision instruments. C. Physical mechanical property: Physical mechanical property mainly refers to the ability of medical protective suit materials to resist tearing, puncture and wear. Avoid tearing and puncturing to provide a channel for the spread of bacteria and viruses, and wear resistance can prevent the flocculation to provide a place for the reproduction of bacteria and viruses. D. Other performance: In addition to the properties listed above, protective suit should also have the properties of disinfection tolerance, good color fastness to washing, shrinkage resistance, non-combustion-supporting, non-toxic and non-irritating, and harmless to skin. What are the special protective suit? A. Chemical protective suit: Chemical protective suit is a kind of protective clothing to protect oneself from dangerous chemicals or corrosive substances when dealing with dangerous medical chemicals. Chemical protective suit requires not only chemical resistance of clothing materials, but also more stringent requirements for sealing and seam structure of clothing. B. Electromagnetic radiation protective suit: Electromagnetic radiation protective suit is a kind of protective clothing which can shield electromagnetic waves in the range of 100 kHz to 300 GHz by implanting very fine conductive fibers in fabric materials, so that protective suit does not produce static electricity. It is mainly used for operators of electronic medical equipment systems in hospitals. C. Nuclear and X-ray protective suit: Radiation environment (small dose and large range of ionizing radiation, mainly alpha and beta rays) to prevent the harm of radioactive aerosol and dust to human body. It has the functions of protecting radioactive aerosols, more than 150 kinds of toxic and corrosive gases,CE Certificate KN95 Mask, liquids and solids, potential radioactive particles and liquids from invading the body, and 100% blocking dry particles above 0.2 μm.
