Medical protective clothing performance requirements(1)
- Jan 02, 2018 -

Medical protective clothing and ordinary chemical protective clothing is different, in addition to protective clothing material itself specifications and safety requirements, the performance of medical protective clothing are also mainly include: protection, comfort, physical and mechanical properties and other aspects.The company is located in:


First, protective

Protective is the most important performance requirements of medical protective clothing materials, including liquid barriers, microbial barriers and barriers to particulate matter.


The first is liquid barrier properties of medical protection. Operating suits worn during surgery inevitably face the patient's blood, body fluids and other secretions, and these fluids often become the best route for transmission of the virus. The use of protective clothing is mainly due to people aware of the risk of blood-borne transmission, medical protective clothing should be able to stop water, blood, alcohol penetration, so as not to contaminate clothes and the human body.


The barrier to microbes can be divided into barriers to bacteria and viruses. As the microorganisms may reach open wounds during surgery, most surgical infections are triggered during this process. Operating room staff and the patient's skin Common microbial bacteria from the operatives to the wounds of the direct contact of sexual transmission and reverse transmission. The barrier requirements of the virus are mainly taken into account that the patient's blood and body fluids may contain pathogenic viruses. In particular, if it is determined that the patient carries or may carry a strong infectious disease, if the medical and nursing personnel have traumatic skin contact with These liquids are likely to be transmitted, and even cause cross-infection between doctors and patients.


Therefore, protective clothing should also be able to prevent the penetration of bacteria, viruses and other microorganisms. The filtration efficiency of particulate matter is required because some viruses are spread through the air, inhaled in the form of aerosols or absorbed by the human body and attached to the surface of the skin. In this case, the SARS virus is harmful. Therefore, Protective clothing materials should also have the ability to block the particles.


Second, comfort

As a body-worn material, medical protective clothing should be worn in the process as far as possible burst out a certain degree of comfort, which performance is affected by many factors, including: breathable, water vapor permeability, drape, quality, Electrostatic properties, color, reflectivity, odor and skin sensitization, as well as the effects of design and sewing on finished products.


The most important manifestation of breathable, breathable, in order to achieve the desired protective effect, protective clothing fabrics usually laminated or laminating treatment, often thick and breathable, poor moisture permeability. Long-term wear of medical staff, the body produces a lot of heat, if not discharged in time, will increase irritability, affecting work efficiency and health.


Anti-static requirements are mainly due to the special operating room environment, static electricity will not only lead to material adsorption of large amounts of dust and bacteria, the patient's wound infection, and also health care workers will cause discomfort. At the same time static electricity sparks may detonate volatile gases in the operating room, thus affecting the accuracy of precision instruments.
