Dear staff, wearing masks is one of the important means to prevent respiratory infectious diseases such as novel coronavirus. How to choose and wear masks correctly can play a protective role. Let's study together.
1. What mask is useful?
1. Ordinary paper masks, activated carbon masks, cotton masks, and sponge masks have limited anti-infection effects due to the lack of fine materials. It is recommended that you do not use them.
2. Medical surgical masks that can prevent respiratory tract infection to a certain extent are recommended for everyone to wear. Secondly, they can effectively prevent respiratory tract infection, but they will cause suffocation when worn, including N95, KN95, DS2 and FFP2.
Second, how to wear a mask correctly?
1. Wash your hands first. It is best to wash your hands with soap or disinfectant.
2. Confirm the inside and outside. The dark color is outside, the light color is inside, and the end with the metal strip is facing up.
3. Cover your nose and mouth. Hang up the ear strap, press the bridge of the nose and pull down the mask.
4, the bridge of the nose is close to the bridge of the nose. Press the sides of the bridge of the nose tightly, close to the face, completely cover the nose, mouth and chin to ensure tightness.
Third, the precautions for wearing a mask
Replace it regularly. Replace it every 2-4 hours. When the mask is wet or contaminated by secretions, it should be discarded in time and replaced with a new clean and dry medical mask.
Fourthly, dispose of the used masks correctly and effectively.
1. For ordinary people, because of the low risk, used masks can be directly thrown into the trash can.
2. If people have cold or flu-like symptoms (fever, cough, stuffy nose, runny nose, sneezing and fatigue), it is best to pack them in self-sealing bags and dispose of them properly as medical waste.
3, don't cut, because droplets may pollute the scissors. Don't use boiling water to scald the mask, which will increase the risk of infection during surgery.
