The medical protective suit refers to 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, people entering infected areas, etc.).
Through the isolation of germs, harmful ultra-fine dust, acid-base solutions, electromagnetic radiation, etc., medical protective suit plays a role in ensuring human safety and keeping the environment clean. So what are the performance requirements for protective clothing processing?
In addition to the specifications and safety requirements of the material itself, the performance of medical protective suits mainly includes protection, physical and mechanical properties, etc.
The protective property of protective clothing processing is an important performance requirement in a medical protective suit, mainly including liquid blocking, microbial blocking, particle material blocking, etc.
Liquid barrier property means that a medical protective suit needs to be able to prevent the penetration of liquids such as water, blood, and alcohol, and has a hydrophobicity of level 4 or higher, so as not to contaminate clothes and the human body. Avoid infecting the medical staff with the virus carried by the patient's blood, body fluids, and other secretions during the operation.
The blocking properties of microorganisms include blocking of bacteria and viruses. Barriers to bacteria are primarily to prevent contact transmission (and back-transmission) by healthcare workers during surgery on patients' surgical wounds.
The barrier of medical disposable protective clothing to viruses is mainly to prevent medical staff from contacting the blood and body fluids of patients, and the viruses carried in them can cause diseases between cross-infections.
Particulate matter blocking refers to preventing airborne viruses from being inhaled in the form of aerosols or attached to the skin surface and absorbed by the human body.
Comfort includes breathability, water vapor permeability, prominence, quality, surface thickness, electrostatic properties, color, reflectivity, odor, skin sensitivity, etc. Of course, the important thing is ventilation and moisture permeability.
In order to improve the protection effect, medical disposable protective clothing fabrics are usually treated with layers or peritoneal membranes, which are thick, have poor air permeability and moisture permeability, and are not conducive to perspiration after long-term wear.
The anti-static requirement is to prevent the static electricity in the operating room from causing the surgical gown to absorb a large amount of dust and bacteria, and to prevent the sparks caused by static electricity from exploding the volatile gas in the operating room and affecting the accuracy of the instrument.
3. Physical and mechanical properties of medical protective suit
The physical and mechanical properties of medical disposable protective clothing mainly refer to the tear resistance, puncture resistance and wear resistance of medical protective suit materials.
Avoid tears, stab wounds, provide a channel for the spread of bacteria and viruses, and if medical protective suit is resistant to abrasion, it can prevent providing a place for bacteria and viruses to multiply.
4. Other properties of medical protective suit
In addition to the properties listed above, the processing of medical protective suit also requires disinfection resistance, good color fastness to washing, shrinkage prevention, burning prevention, non-toxic, non-irritating, skin-friendly properties, and more.
