Performance requirements for medical protective clothing
1. Protection
Protective performance is an important requirement for medical protective clothing, including liquid barrier, microbial barrier and particle barrier.
Liquid barrier property means that medical protective clothing must be able to prevent the penetration of water, blood, alcohol and other liquids, and must have a hydrophobicity of 4 or more to prevent clothing and human infection. Avoid infection with viruses transmitted to medical personnel during surgery by the patient's blood, body fluids, and other secretions. The microbial barrier includes a barrier to viruses. The virus barrier is intended to prevent medical personnel from touching the surgical wound transferred to the patient during surgery. Virus isolation is mainly to prevent cross-infection between doctors and patients caused by viruses carried by medical personnel when they come into contact with patients' blood and body fluids. Particulate matter barriers prevent airborne viruses from being inhaled or attached to the surface of the skin in the form of aerosols and absorbed by the body. Guangxi Medical Supplies
2. Comfort
Comfort includes breathability, water vapor permeability, drape, quality, surface thickness, electrostatic properties, color, reflectivity, odor, skin, etc. Mainly with regard to breathability and moisture permeability, in order to improve protection, protective clothing fabrics are usually laminated, resulting in thick and poor breathability and moisture permeability. Long-term wear is not conducive to perspiration and heat dissipation. The anti-static requirement is to prevent static electricity in the operating room from causing the surgical gown to absorb a large amount of dust, to prevent the spark generated by static electricity from exploding the volatile gas in the operating room and affecting the accuracy of precision instruments.
3. Physical and mechanical properties
Physical and mechanical properties mainly refer to the possibility of tear resistance, leakage resistance and wear resistance of medical protective clothing materials. Tear and puncture areas should be avoided to provide channels for the spread of the virus, and wear-resistant areas can prevent flocs from falling and create places for the spread of the virus.
4. Other benefits
In addition to the above properties, medical protective clothing should also have durability, good color fastness to washing, shrinkage resistance, non-burning, non-irritating and harmless to the skin. Guangxi Medical Equipment Company
