Medical surgical masks are protective equipment used in high demand environments such as medical clinics, laboratories, and operating rooms. They are mainly worn by medical staff during work to protect them from pathogens, microorganisms, body fluids, particulate matter, etc. The following is a detailed introduction about medical surgical masks:

product overview

Medical surgical masks are a type of medical protective textile, often made of one or more layers of non-woven fabric composite. The main production processes include melt blown, spunbond, hot air or needle punched, etc. They have the equivalent functions of resisting liquids, filtering particles and bacteria.

Product Features

Material characteristics:

Meltblown fabric: mainly made of polypropylene, with fiber diameters ranging from 0.5-10 microns, it has good filtration, shielding, insulation, and oil absorption properties.

Spunbond nonwoven fabric: high strength, good high temperature resistance, aging resistance, UV resistance, high elongation, good stability and breathability, corrosion resistance, sound insulation, anti moth, non-toxic.

Structural features:

Three layer structure: the inner layer is a skin friendly non-woven fabric with moisture absorption function, the middle layer is a medical meltblown fabric with electrostatic adsorption and filtration of bacteria and viruses, and the outer layer is a non-woven fabric that can effectively prevent splashing of blood, body fluids, secretions, etc.

Usage

Carefully cover your mouth and nose with a mask and fasten it securely.

Only by distinguishing between the inside and outside, top and bottom, and wearing it correctly can the protective effect be achieved.

Masks are disposable and not recommended for repeated use. If worn continuously for 4 hours or if feeling damp, they should be replaced in a timely manner.

TECHNICAL INDEX

Medical surgical masks must comply with the Chinese pharmaceutical industry standard YY 0469-2011 "Technical Requirements for Medical Surgical Masks", and the main technical indicators include:

Filtration efficiency: Under the condition of air flow rate (30 ± 2) L/min, the filtration efficiency of sodium chloride aerosol with a median diameter of (0.24 ± 0.06) μ m in aerodynamics is not less than 30%.

Bacterial filtration efficiency: Under specified conditions, the filtration efficiency for Staphylococcus aureus ATCC6538 is not less than 95%.

Pressure difference: Under specified conditions, the pressure difference for gas exchange between the two sides of the mask should not exceed 49Pa.

Synthetic blood penetration: After 2ml of synthetic blood is sprayed towards the outer side of the mask at a pressure of 16.0kPa (120mmHg), there should be no penetration on the inner side of the mask.

scope of application

Medical surgical masks are suitable for high demand environments such as medical clinics, laboratories, and operating rooms, and are masks worn by medical staff during work. It can also be used for preventing influenza. If you need to come into contact with patients with H1N1 influenza or stay in crowded and unventilated places for a long time, you should wear a mask for personal protection.
