Prevention and application types of medical surgical masks

When wearing a Medical Mask, the appropriate level should be selected according to the transmission type and risk degree of pollutants, and should not be too high or too low. The medical protective mask with high protection grade has good protection effect, but due to the high content of filter material, good adhesion and large respiratory resistance, wearing it for a long time will increase the respiratory burden and cause discomfort such as dyspnea. Medical surgical masks and medical protective masks can prevent the pollution caused by blood and body fluid splashing, but if it is really necessary to prevent the pollution of particles and pathogenic microorganisms in the air, please choose to wear medical protective masks.

Disposable Protective Mask

Medical surgical masks can block most bacteria and some viruses, prevent medical personnel from being infected and prevent medical personnel from transmitting pathogens to the outside world. Therefore, it is applicable to the basic protection of clinical medical personnel, that is, clinical medical personnel wear it during invasive surgery. It can provide protection for patients receiving treatment and medical personnel receiving invasive surgery, and prevent blood, body fluid and splashing.
During the epidemic period of infectious diseases, medical surgical masks can effectively prevent the spread of pathogens and protect all kinds of personnel in relatively dense places, such as hospital outpatient guidance, elevator, emergency room, etc.
In principle, the replacement time of medical surgical masks is 4 hours. However, due to the serious epidemic situation, under the premise of relative shortage of masks, the time can be appropriately relaxed, but it can not exceed 24 hours. For doctors, if they work in important places such as infection department and outpatient service, they must be replaced every 4 hours. However, if ordinary people need to go shopping, or when they work, they can be sterilized with alcohol, or after 84 spray disinfection, they can be reused. It is suggested that they should not be replaced after 48 hours. For healthy people, it is recommended to wear disposable masks under normal travel conditions, but it is not recommended to use reusable masks and cross used masks.
