What are the performance requirements of medical protective clothing?

Update:22 Feb
In addition to the specifications and safety requirements of the material itself, the performance of medical protective clothing mainly includes protection, comfort, physical and mechanical properties, etc.

1. Protection
      Protection is the most important performance requirement of medical protective clothing, which mainly includes liquid barrier, microbial barrier, and barrier to particulate matter.

      Liquid barrier property means that medical protective clothing should be able to prevent the penetration of water, blood, alcohol and other liquids, and have a hydrophobicity of level 4 or higher to avoid staining clothes and the human body. Avoid transmitting the virus carried by the patient’s blood, body fluids and other secretions to medical staff during the operation.

      Microbial barrier properties include barriers to bacteria and viruses. The barrier to bacteria is mainly to prevent the contact transmission (and reverse transmission) of medical staff to the patient's surgical wound during the operation. The barrier to the virus is mainly to prevent the medical staff from contacting the blood and body fluids of the patient, and the virus carried therein can cause cross infection between the doctor and the patient.

      The barrier property of particulate matter refers to the prevention of viruses spread through the air from being inhaled in the form of aerosol or attached to the skin surface and absorbed by the body.

2. Comfort
      Comfort includes breathability, water vapor penetration, drape, quality, surface thickness, electrostatic properties, color, reflectivity, odor, and skin sensitization. The most important thing is breathability and moisture permeability. In order to enhance the protective effect, protective clothing fabrics are usually laminated or laminated, resulting in heavy weight and poor breathability and moisture permeability. Long-term wearing is not conducive to perspiration and heat dissipation.
      The antistatic requirement is to prevent static electricity in the operating room from attracting a large amount of dust and bacteria to the patient's wounds, and 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
      The physical and mechanical properties mainly refer to the tear resistance, puncture resistance and abrasion resistance of medical protective clothing materials. Avoid tears and punctures to provide channels for the spread of bacteria and viruses, and wear resistance can prevent flocculation and provide places for bacteria and viruses to multiply.

4. Other properties
      In addition to the properties listed above, medical protective clothing also needs to have disinfection tolerance, good color fastness to washing, prevent shrinking, non-combustible, non-toxic, non-irritating, and harmless to the skin.
