Medical protective clothing
Medical protective clothing refers to protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning staff, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its role is to isolate bacteria, harmful ultra-fine dust, acid and alkali solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
In addition to the specifications and safety requirements of the material itself, the performance of medical protective clothing mainly includes aspects such as protection, comfort, and physical and mechanical properties.
Microbial barriers include barriers to bacteria and viruses. The barrier to bacteria is mainly to prevent contact transmission (and back propagation) of medical personnel to the patient's surgical wound during the surgery. The virus barrier is mainly to prevent the medical staff from contacting the patient's blood and body fluids, and the virus carried in it causes cross infection between doctors and patients.
Particulate matter barrier refers to preventing viruses transmitted through the air from being inhaled or attached to the skin surface and absorbed by the body in the form of aerosols.
Comfort includes breathability, water vapor permeability, drapability, quality, surface thickness, electrostatic properties, color, reflectivity, odor, and skin sensitization. The most important is breathability and moisture permeability. In order to enhance the protective effect, protective clothing fabrics are usually laminated or laminated, resulting in heavy, breathable and poor moisture permeability, which is not conducive to perspiration and heat. The antistatic requirement is to prevent the static electricity in the operating room from causing the surgical clothes to absorb a large amount of dust and bacteria which is not good for the patient's wounds, and at the same time to prevent sparks generated by static electricity from detonating volatile gases in the operating room and affecting the accuracy of precision instruments.
3. Physical and mechanical properties
Physical and mechanical properties mainly refer to the ability of medical protective clothing materials to resist tearing, puncture and abrasion. Avoid tears and punctures to provide a channel for bacteria and viruses to spread, and abrasion resistance can prevent flocs from providing a place for bacteria and viruses to multiply.
4. Other properties
In addition to the properties listed above, medical protective clothing must also have disinfection resistance, good color fastness to washing, prevention of shrinkage, non-combustibility, non-toxicity and non-irritation, and harmless to the skin.
