The main function of medical masks: used to wear on the mouth and nose of medical personnel or related personnel, play a two-way biological protection. Main advantages: surgical masks can prevent the spread of respiratory diseases. Price range: different regions of the hospital price standards are slightly different, specific to the local hospital consultation.

   Medical masks are generally made of non-woven materials, mainly made of masks, molded parts, belts and other components, and have a wide range of applications. Through filtration, the medical mask reduces the microorganisms carried by the mask into the air, prevents the patient's body fluid from overflowing and causes the wearer's infection, realizes two-way isolation, and has strong resistance to bacteria and viruses.

The main function of medical masks: used to wear on the mouth and nose of medical personnel or related personnel, play a two-way biological protection. Main advantages: surgical masks can prevent the spread of respiratory diseases. Price range: Hospitals and price standards in different regions are slightly different. For details, you can consult the local hospital. Medical surgical masks are a kind of infection control products worn by medical personnel or related personnel in high-demand environments such as medical clinics, laboratories, and operating rooms.


   Wear in the operating room, during aseptic procedures, or when caring for immunocompromised patients to prevent the wearer from transmitting pathogens to the patient. Body cavity puncture or invasive surgery to protect medical personnel from infection by leakage of blood, body fluids or secretions. Relatively crowded places, such as community, hospital consultation or consultation, elevator, emergency, etc. Infected patients filter out microbes in their breath.


   According to the classification of technical standards and scope of application, medical surgical masks should be equipped with a nose clip made of flexible material with a length of not less than 8cm; the filtration efficiency of the mask should be greater than 95%, and for non-oily particles, the filtration efficiency should be no less than 30%.


   Medical protective mask masks must be equipped with a nose clip made of flexible material with a length of not less than 8.5cm; Under the gas flow rate of 85L/MIN, the inhalation resistance of the mask should be less than 343.2PA. When spraying synthetic blood at a pressure of 80MMHG(10.7KPA) on the outside of the mask sample, there is no leakage on the inside of the mask; the material should be free of skin irritation; the outer package should be marked with the product standard number GB19083-2003.


   Gauze masks and ordinary disposable masks The material is multi-layer gauze or ordinary non-woven fabric, its structure can not achieve a certain particle filtration efficiency or bacterial filtration efficiency, dust particles or bacteria, virus particles only play a certain mechanical blocking effect, no national standards or industry standards.


   How do medical masks work? Medical surgical masks are mainly divided into two types: ear type and belt type. Their appearance is similar to ordinary disposable masks, with only one layer. The medical surgical mask has three layers, namely the surface layer, the middle layer and the inner layer, all of which are SMS structure.


The surface layer of medical surgical masks is mainly made of sanitary spunbond polypropylene (PP) non-woven fabric, which is waterproof. It is generally single-layer, and the rolling point is rhombus. It can isolate liquid, has the characteristics of corrosion resistance, wear resistance, ultraviolet resistance, good air permeability and good hand feeling.


   The middle layer of the medical mask is a superfine polypropylene fiber meltblown non-woven fabric with long-lasting static electricity. Generally, it is a single layer or multiple layers. In the production process, it needs to be treated with electret to make it a dielectric material with long-term charge storage function, which can rely on the electrostatic effect to produce an effect on the abdominal muscles.
