Spring is the season when flu is frequent. In this season, we should wear more masks to prevent it. Then there are many types of masks, so can medical masks prevent flu?

 

Do medical masks prevent flu?

Medical surgical masks can block most bacteria and some viruses. Its filtration efficiency for bacteria is greater than 95%, but the filtration efficiency for fine dust in the air is not high, and its filtration efficiency is 70%-80%. It has a strong function of blocking the spread of germs. Medical protective masks Compared with medical surgical masks, medical protective masks fit the face more closely, and the high-efficiency particle filtration efficiency of more than 95% indicates that it is more effective in anti-virus and dust-proof. Functionally, medical protective masks are an upgraded version of surgical masks. Medical surgical masks and N95 masks have no difference in protection against influenza, and there is no difference in protection against other respiratory viruses except SARS. Medical protective masks cannot effectively prevent the spread of pathogens from patients to the outside world, so they are not suitable for patients with respiratory infectious diseases. Therefore, the main function of medical protective masks is to be worn by professional medical workers to protect against severe infectious diseases.

What are the standards for flu masks

As a kind of cotton gauze or knitted fabric, the anti-flu mask has no interlayers in between, so it can prevent the flu. But we should remind everyone that masks cannot filter bacterial particles in the air. If they can filter bacterial particles, then the flu virus will not be produced at all. Although anti-flu masks have certain effects, they cannot be solved entirely by masks. When we understand other aspects, we also need to recognize other ways to prevent influenza. Masks can only be used as an auxiliary measure. We must have a clear understanding of more methods and methods. Only in this way can we truly avoid the impact of flu disease on human society over a long period of time.

 

How to choose a medical mask

Medical masks are divided into ordinary medical masks, medical surgical masks and medical protective masks, and their protection levels are gradually increased: 1) Ordinary medical masks generally lack filtration efficiency requirements for particles and bacteria, or require low filtration efficiency for particles and bacteria. For medical surgical masks and medical protective masks. Ordinary medical masks are generally ear-mounted, which can be used for one-time hygiene care in ordinary environments, or to block or protect particles other than pathogenic microorganisms such as pollen. 2) Surgical masks are divided into 3 layers. The outer layer has a water blocking effect to prevent droplets from entering the mask, the middle layer has a filtering effect, and the inner layer has a moisture absorption effect. Medical surgical masks are generally lace-up type, which are suitable for basic protection of medical staff or related personnel, as well as protection to prevent the spread of blood, body fluids and splashes during invasive operations. Compared with ordinary medical masks, medical surgical masks have a better barrier effect on respiratory infectious diseases, and the dustproof effect is better than ordinary medical masks, but compared to medical protective masks, the level of protection of medical surgical masks is slightly weaker. . 3) Medical protective masks are suitable for the protection of airborne respiratory infectious diseases, and have a very good barrier effect on dust and haze. The protection level is the highest among these types of masks. The N95 masks we often talk about fall into this category.

 

The role of using medical masks

Cotton gauze mask: The outer layer is a special material antibacterial layer, which can be simply filtered and has a dust-proof effect. The middle layer is an isolation filter layer to isolate the virus contained in the hospital air. The inner layer is made of skin-friendly material with a comfortable inner quality. The ventilation effect is strong, making people feel comfortable. Medical surgical mask: It is used to prevent the droplet splashing of influenza patients, and has no protective effect on haze. Disposable masks can prevent the patient's saliva from splashing outside, and the focus is on the surrounding people. N95 medical protective mask: Respiratory protection of certain particulate matter, such as dust generated in the process of grinding, cleaning and processing minerals, flour and certain other materials. It is also suitable for liquid or non-oily substances produced by spraying and does not cause harmfulness. Particulate matter of volatile gas. It can effectively filter and purify the inhaled abnormal smell (except toxic gas). It can help reduce the exposure level of certain inhalable microbial particles (such as mold, anthracis, tuberculosis, etc.), but it cannot eliminate the risk of contact with infection and illness.
