According to the different requirements of wholesale inflatable laryngeal mask grade, the nonwovens and films used are also different. Polyethylene breathable film/nonwoven fabric composite material, for blocking the penetration of bacterial particles and liquid penetration has excellent effect, and feel can be adjusted by changing the softness of composite fabric, its strong tensile strength, good air permeability, comfortable performance is greatly improved, can withstand disinfection treatment, does not contain toxic ingredients, gram weight 60~100g/m2, has a good cost performance, The medical disposable protective suit made from it can protect medical personnel from pollution sources, overcome cross infection and play an effective role in protection.

A. Protection:

Protection is the most important performance requirement of wholesale inflatable laryngeal mask, including liquid barrier, microbial barrier and granular material barrier.

Liquid barrier: wholesale inflatable laryngeal mask should be able to prevent the penetration of water, blood, alcohol and other liquids, with hydrophobicity of more than 4, so as not to stain clothes and human body. Avoid infecting medical personnel with the virus carried by the patient's blood, body fluids and other secretions during the operation.

Microbial barrier: including the barrier to bacteria and viruses. The barrier of bacteria is mainly to prevent contact transmission (and reverse transmission) from medical staff to patients' surgical wounds during surgery. The main barrier to the virus is to prevent health care workers contact with patients' blood and body fluids, which carry the virus to cause cross-infection between doctors and patients.

Particulate matter barrier: prevent airborne viruses from being inhaled in the form of aerosols or attached to the skin surface for absorption by the human body.

B. Comfort:

Comfort includes air permeability, water vapor penetration, drape, mass, surface thickness, electrostatic properties, color, reflectivity, odor, and skin sensitization.

The most important is the breathability and moisture permeability. In order to enhance the protective effect, the fabric of protective clothing is usually laminated or laminated, resulting in thick, breathable and poor moisture permeability. Long-term wearing is not conducive to sweat and heat removal.

The antistatic requirement is to prevent static electricity in the operating room from causing a large amount of dust and bacteria to be absorbed by the operating gown, which is detrimental to the wound of the patient, and prevent sparks generated by static electricity from detonating volatile gases in the operating room and affecting the accuracy of precision instruments.

C. Physical and Mechanical properties:

The physical and mechanical properties mainly refer to the tear resistance, puncture resistance and abrasion resistance of wholesale inflatable laryngeal mask materials. Avoid tearing and puncturing to provide a channel for the spread of bacteria and viruses. Wear resistance can prevent floc from providing a place for the propagation of bacteria and viruses.

D. Other performance:

In addition to the properties listed above, wholesale inflatable laryngeal mask should be sterilizing tolerant, have good color fastness to washing, prevent shrinkage, be non-flammable, non-irritating, and be harmless to the skin.
