Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breathing mask. Background technique [0002] Novel coronavirus pneumonia is an acute infectious pneumonia, and its pathogen is a new type of coronavirus not previously found in humans, namely 2019-nCoV. Based on the current epidemiological research, the transmission of the new coronavirus through respiratory droplets and close contact is its main transmission route. [0003] Patients with COVID-19 generally have symptoms such as fever, fatigue, and coughing. When coughing, a large number of droplets are produced. The droplets carry a large number of highly pathogenic microorganisms, such as bacteria, viruses, and mycoplasma. Pathogenic microorganisms are easily contaminated and cross-infect medical staff. Personnel and other patients, during treatment in the prior art, the patient often wears the special mask that cooperates ventilator treatment in treatment, but all ...

[0003] Patients with COVID-19 generally have symptoms such as fever, fatigue, and coughing. When coughing, a large number of droplets are produced. The droplets carry a large number of highly pathogenic microorganisms, such as bacteria, viruses, and mycoplasma. Pathogenic microorganisms are easily contaminated and cross-infect medical staff. Personnel and other patients, during treatment in the prior art, the patient often wears a special mask that cooperates with a ventilator for treatment, but the special mask is provided with vent holes, and droplets can still be discharged through the vent holes to cause infection.
