Medical protective clothing refers to the protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solution, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
The performance requirements
1. The protective
Protective property is the most important performance requirement of medical protective clothing, mainly including liquid barrier, microbial barrier and barrier to particulate matter.
Liquid barrier refers to the medical protective clothing 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 the clothes and human body. Avoid the patient's blood, body fluids and other secretions during the operation to transmit the virus to the medical staff.
Microbial barrier includes the barrier to bacteria and viruses. The main purpose of bacterial barrier is to prevent contact transmission (and back transmission) from the medical staff to the patient's surgical wound during surgery. The main barrier to the virus is to prevent health care workers from contact with the blood and body fluids of patients, which carry the virus causing cross-infection between doctors and patients.
Particle matter barrier refers to preventing airborne viruses from being inhaled as aerosols or being absorbed by the body when attached to the skin.
2. The comfort
Comfort includes air permeability, water vapor penetration, drape, quality, surface thickness, electrostatic properties, color, reflective, odor and skin sensitization, etc. The most important performance is air permeability and moisture permeability. In order to enhance the protective effect, protective clothing fabric is usually treated by laminating or laminating, resulting in thick and poor air permeability and moisture permeability. Long-term wearing is not conducive to sweat and heat removal. The antistatic requirement is to prevent the static electricity in the operating room will lead to the absorption of a large number of dust and bacteria on the patient's wound, and prevent the spark generated by static electricity from detonating volatile gas in the operating room, affecting the accuracy of precision instruments.
3. Physical and mechanical properties
Physical and mechanical properties mainly refer to the tear resistance, puncture resistance and wear resistance of medical protective clothing materials. Avoid tearing and puncturing places to provide channels for the spread of bacteria and viruses, and wear resistance can prevent flocculating places to provide places for the reproduction of bacteria and viruses.
4. Other properties
In addition to the properties listed above, medical protective clothing should also have disinfection resistance, good color fastness to water washing, shrinkage resistance, non-inflammable, non-toxic, non-irritating, and harmless to the skin.
