The mask fixing method is simple.

Ordinary masks are divided into ordinary medical masks and medical surgical masks. The outside of the medical surgical mask is blue, so when I put it on, my blue face rushes out. Ordinary medical masks are white inside and outside, so when you wear them, you must distinguish the opposite. Whether it is a medical surgical mask or an ordinary mask, remember that the side of the fixed mask belt must face yourself, and you can wear it correctly by distinguishing the reverse side. Take the medical surgical mask as an example to demonstrate the correct wearing method, as follows: 1. Before wearing a mask, be sure to keep your hands clean, and use the seven-step washing method to clean your hands in a standardized way to avoid polluting the clean mask with contaminated hands and achieve the best protective effect; 2. When wearing a mask, hold the straps on both sides and put them on your ears. After holding them, open the mask and cover the nose and chin at the bottom. There is a steel wire on the upper mask. Pressing the steel wire with both hands and sticking it on the bridge of the nose can have a good sealing effect and the best protection effect. 3. It is generally not recommended to wear a mask for more than 4 hours. If there is no contact with suspected or confirmed patients, and there is no obvious dirt and liquid infiltration, the wearing time can be appropriately extended, but it is not recommended to wear a mask for more than 24 hours; 4, when contact with suspected or diagnosed patients, especially medical staff in infectious disease wards, when leaving the ward and patients, they should take off their masks and throw them away as medical waste to prevent pollution to others.
