Performance requirements of medical comsumables such as protection suit

Medical protection suit is a protection suit used by medical personnel and people who enter specific medical and health areas. The following is a description of the performance requirements for a protection suit.

Here is the content list:

• Protective properties

• Comfort

• Physical and mechanical properties

Protective properties

Protection is the most important performance requirement of medical protection suit, mainly including liquid barrier, microbial barrier, and barrier to particulate matter.

Liquid barrier refers to the medical protection suit that 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 transmission of viruses carried by the patient's blood, body fluids, and other secretions to medical personnel during surgery.

The microbial barrier includes a barrier to bacteria and viruses. The barrier for bacteria is mainly to prevent contact transmission (and reverse transmission) from medical personnel to the patient's surgical wound during surgery. The barrier to viruses is to prevent cross-infection between patients and doctors caused by viruses carried in the blood and body fluids of the patients when the health care workers come into contact with them.

Particulate matter barrier refers to preventing viruses that are transmitted through the air from being inhaled in the form of aerosols or being absorbed into the body by adhering to the skin surface.

Comfort

Comfort includes breathability, water vapor permeability, quality, surface thickness, electrostatic properties, color, reflectivity, odor, and skin sensitization. The main thing is breathable, moisture permeability performance, to enhance the protective effect, protection suit fabrics are usually laminated or compound film processing, resulting in thick and breathable, moisture permeability is poor, long-term wear is not conducive to sweat and heat. Antistatic requirements are to prevent static electricity in the operating room will lead to the surgical gown adsorption of a large amount of dust and bacteria to the detriment of the patient's wound, while preventing sparks generated by static electricity to detonate volatile gases in the operating room, affecting the accuracy of precision instruments.

Physical and mechanical properties

Physical and mechanical properties mainly refer to the ability of the medical protection suit material to resist tearing, puncture, wear, and tear. Avoid tearing, puncture at the place for bacteria, and virus transmission to provide access, wear and tear can prevent the place for bacteria and virus reproduction at the place of falling wool.

Other properties

In addition to the properties listed earlier, medical protection suits should also have disinfection resistance, good colorfastness to washing, prevention of shrinkage, non-combustion, non-toxic and non-irritating, harmless to the skin, and other properties.
