However, there are many precautions for wearing masks in daily life. Here is a brief introduction to the users, hoping to help them.
It is not necessary to wear masks for a long time. Wearing masks for a long time is not only uncomfortable, but also unnecessary. It is often seen that some people walk on the open street with masks on, which is meaningless from the point of view of preventing the spread of disease. In the current flu season, it is recommended that the public wear masks when they encounter the following situations: going to the fever clinic of the hospital by themselves or with their family members; taking care of the patients with respiratory tract infection such as mild H1N1 flu at home; when the patients with mild influenza go out for close contact with others; when taking public transportation such as bus and subway.
Use the mask correctly. Usually the disposable mask bought in the drugstore is a medical general surgical mask. Wash your hands before wearing, so as not to pollute the inner face of the mask. After wearing the mask, use your hands to pull the folds of the mask up and down at the same time, so that the mask completely covers the nose and chin, and press the metal strips on both sides of the nose with your fingers, so that the upper end of the mask can be close to the nose, so as to better It has protective effect.
Pay attention to the degree of tightness with the shape of the face. The air is like the water flow. Where the resistance is small, it flows first. When the shape of the mask is not close to the face, the dangerous substances in the air will leak into the respiratory tract from the non close place. Well, even if you choose the best filter. It can't protect your health. At present, many foreign regulations and standards stipulate that workers should regularly test the tightness of masks. The purpose is to ensure that workers choose appropriate masks and wear them according to the correct procedures.
Be diligent in cleaning, there will be saliva in the part of the inner face of the mask contacting the nose and mouth. If not, bacteria will easily grow, which does not meet the requirements of health. Cotton masks usually have coarse fibers, which can not effectively filter small particles, and most of them fail to pass the international safety certification, so the protection effect is not guaranteed. Gauze mask is almost useless, and the air leakage on both sides of nostril is too large.
