1 the different filtration rate is one of the differences between medical masks and protective masks. The filtration rate of protective masks for non-oily particles can reach more than 95%. It is a commonly used personal protective equipment to deal with airborne diseases, while medical masks can block blood body fluids from passing through the mask, and the filtration rate of bacteria is more than 70%. The filtration rate of particulate matter is limited. 2 different shapes of protective masks have a good fit with the wearer's face. The key difference between medical masks and protective masks is that the filtration rate and use of protective masks are excellent in filtering non-oily particles, reaching a filtration rate of more than 95%, which is an effective personal protective equipment against airborne diseases. Medical masks focus on blocking blood and body fluids to prevent contamination of the wearer, and the filtration rate of bacteria is more than 70%. But the ability to filter particulate matter is limited to protect the face of the mask and the wearer.
First-level protection is aimed at medical staff in medical institutions, requiring them to wear work clothes, disposable hats and isolation clothes, and to wear disposable surgical masks after each contact with patients, they should use iodophor disinfectant or itsMask protectionHe uses disinfectant to rub and disinfect his hands for 1 to 3 minutes. When he comes into contact with any body fluid secretions or other substances, he must wear gloves for secondary protection, which is suitable for the prevention and control of infectious diseases. Medical staff involved in collecting samples and transferring patients are required to wear medical protective clothing. 1 Protective mask is a kind of mask used to block suspended particles in the air, mainly used to protect against substances harmful to the respiratory system, such as dust, particulate matter, smoke, etc. They are usually made of multi-layer filter materials. protective masks such as cellulose activated carbon and electrostatic materials are widely used in construction, metallurgy, chemical industry, mining and other industries, as well as air pollution in daily life 2 medical masks are specially used The mask grade d protection is that the filtration should reach level 3 or above, and the filtration efficiency of solid particles is more than 90%. The KN90 equivalent to the national standard is equivalent to the American standard N90 standard mask is a kind of sanitary product, which is generally worn on the mouth and nose to filter the air into the mouth and nose, so as to block the harmful gas smell droplets in and out of the wearer's mouth and nose. Masks made of gauze or paper can filter the air entering the lungs to a certain extent. Ordinary masks have a certain protective effect, but they can not completely prevent the spread of viruses. Ordinary cloth masks or paper masks cannot effectively intercept virus particles in the air because of their limited filtering efficiency, so the effect on preventing virus infection is limited by comparison. Medical surgical masks N95 masks or KN95 masks are more effective in preventing the spread of respiratory viruses. Disposable medical masks N95 masks or KN95 masks are preventive. Mask protection refers to the behavior of reducing interpersonal contact and spreading diseases by wearing a mask. Under the current novel coronavirus epidemic, mask protection has becomeMask protectionAn indispensable part of our daily life should wear masks when communicating with others in densely populated areas in public places. Wearing masks to avoid virus transmission can reduce virus transmission through droplets, vague symptoms and an incubation period of up to 14 days are easy.
Mask is a common protective tool, its function is to filter out germs, dust, particles, etc., prevent them from entering the human respiratory tract, and play a role in protecting health during the epidemic of diseases in public places. Wearing a mask can effectively reduce the risk of infection, reduce the spread of the virus and the spread of the mask is very important. It is generally recommended to choose a medical mask or N95 mask for protection the correct way to use a mask is to hold the mask close to the face.
The gas-supplied protective mask of blood and body fluid toxic gas secretion refers to the air-supplied protective mask at the fire site of the chemical plant and the chemical hazard of the military industry, that is, the ordinary individual protective mask is a kind of medical protective textile, it is made of one or more layers of nonwovens, and the main production process includes melt-blown viscous hot air or acupuncture, which has the effect of resisting liquid filtering particles and bacteria.
