Background technique

Currently, during bronchoscopy, the trachea needs to enter through the patient's nasal cavity or oral cavity, and extend into the lower respiratory tract through the glottis. During the entire examination process, the patient's nasal cavity, oral cavity and respiratory tract are open. When the patient coughs or sucks through the bronchoscope, a large amount of droplets and aerosols will be excreted out of the body. In droplets, or in the aerosols carried out of the body by the mist during inhalation anesthesia before bronchoscopy, it will carry infectious bacteria or viruses, which can easily lead to cross-infection of medical staff who perform inspections, especially in the recent new coronavirus. During the outbreak of pneumonia, bronchoscopy is a high-risk procedure that leads to viral cross-infection.

Although there are bronchoscopy masks for protection on the market, they only open perforations at the positions corresponding to the patient's mouth and nose. When medical staff perform tracheal penetration operations, the part inserted through the mask is easily topped by the bronchoscope. The pressure collapses, which brings discomfort to the patient; in addition, during the bronchoscopy, most of the patients will have symptoms such as coughing and increased oral secretions, and the existing mask can only remove the mask for suction when cleaning sputum in the patient's mouth. Phlegm, the protective effect of the mask is greatly reduced.
