Respiratory viruses are viruses which take respiratory tract as a main invasive way and can proliferate in large quantity in airway mucosa epithelial cells so as to cause local infection of respiratory tract or other tissue tracheal viruses outside respiratory tract. Common respiratory virus types include orthomyxoviridae, paramyxoviridae, and the like.
When performing endotracheal intubation, airway manipulation and anesthesia management on patients with respiratory viruses, doctors closely face the patient's respiratory tract, and the secretions, blood or generated droplets or aerosols of the patient are a great threat to the doctor and other personnel in the operating room for viral transmission. Or when the patient with uninfected respiratory viruses faces other infected patients or medical staff in an operating room, the patient is easy to be infected with the respiratory viruses in the state of respiratory tract exposure and perioperative immunity hypofunction, so that postoperative cure is poor.
At present, the protection of the tracheal intubation of the anesthesiologist basically focuses on the secondary protection of the anesthesiologist or the common negative pressure isolation cover which is used by patients and adopts the conventional tracheal intubation method, and comprises an operation hole, an oxygen supply channel and a negative pressure suction hole. However, such masks are also limited to use with patients who require the use of special cannulation tools such as vision, light sticks, bronchofiberscopes, and patients who require the use of bronchofiberscope for chest surgery or for the occurrence of airway complications during surgery. And during airway operation in such patients, there is a higher risk of patient choking leading to spray and aerosol diffusion.
Therefore, a negative pressure isolation cover for a disposable tracheal cannula for reducing the infection of respiratory viruses is provided.
