[0038] The blocking air bag 5 is communicated with a control air pipe 10, the control air pipe 10 extends in the sputum suction channel 401 from the blocking air bag 5 to the top of the sputum suction tube 4, and the end of the control air pipe 10 penetrates the side wall of the top of the sputum suction tube 4. The blocking air bag 5 extends to the tracheal bleeding position, the blocking air bag 5 is tightly attached to the outer surface of the sputum suction branch pipe, and when the blocking air bag 5 reaches the tracheal bleeding position through the observation of the optical fiber medical endoscope, the control air pipe 10 inflates the blocking air bag 5, the blocking air bag 5 is inflated to block the tracheal bleeding position, and the air passage of the blocking air bag 5 is communicated with the lung and the main cannula 1, so that the lung can maintain breathing.

[0039] Working principle:

[0040] In use, the non-circular ring end of the main cannula 1 is slowly inserted into the human trachea, then the isolation valve 2 branch connected to the main cannula 1 is connected to the pipeline of the breathing machine, so that the patient can maintain breathing, then the sputum suction tube 4 is stretched into the human trachea through the isolation valve 2 and the main cannula 1 by compressing the film protective sleeve 3, and the second blocking plug 7 is pulled out to stretch the optical fiber medical endoscope into the sputum suction channel 401, and the optical fiber medical endoscope can be stretched out from the bottom of the sputum suction branch pipe sleeved with the blocking air bag 5 to observe the bleeding position of the human trachea, and when the blocking air bag 5 reaches the tracheal bleeding position, the control air pipe 10 inflates the blocking air bag 5, the blocking air bag 5 is inflated to block the tracheal bleeding position, and the air passage of the blocking air bag 5 is communicated with the lung and the main cannula 1, so that the lung can maintain breathing;

[0041] Since the sputum suction tube 4 is provided with two sputum suction channels 401, the two sputum suction channels 401 can be independently controlled through the two valves and the two control valves 9 of the separation valve 8, so that the two sputum suction branch pipes independently suck the sputum of the human trachea, when the bleeding position is in one of the bronchial tubes, the sputum suction branch pipe sleeved with the blocking air bag 5 is stretched into the bronchial tube to block the bleeding position and suck the sputum, and the other sputum suction branch pipe is stretched into the other bronchial tube to suck the sputum.

[0042] It should be noted that the above content only illustrates the technical idea of the present application, and cannot limit the protection scope of the present application.
