As shown in fig. 2, the present invention further includes a blocking member 50 made of non-metal elastic material, wherein the blocking member 50 is located inside the connecting member body 31, one end of the blocking member is connected to the inner wall of the left port of the body 41 of the deviation humidifying filter 40 of the connecting member body 31, and the other end of the blocking member extends out toward the longitudinal axis of the connecting member body 31 and is suspended at the upper port of the connecting member body 31 in a sealing manner. Therefore, when in use, the lower end of the tracheal intubation tube 10 is assembled and connected with the lower port of the connecting piece 30, the tracheal intubation tube core 20 is inserted into the connecting piece body 31 through the middle opening of the elastic sealing piece 32 and the upper port of the connecting piece 30, the blocking piece 50 is compressed and deformed downwards to give way, and then the tracheal intubation tube core 20 penetrates through the connecting piece 30 to enter the tracheal intubation tube 10, and the tracheal intubation tube 10 is formed into a shape required by a use state; then, the left port of the body 41 of the humidifying filter 40 is connected with the right port of the connecting piece body 31 of the connecting piece 30; finally, the right port of the body 41 of the humidifying filter 40 is connected with an anesthesia respirator, and the lower port of the endotracheal intubation tube 10 is put into the oral cavity of the patient. When the endotracheal tube core 20 is pulled out to discharge sputum containing infectious virus, the blocking member 50, which is compressed and deformed downward by the endotracheal tube core 20 to yield, relatively quickly recovers its original shape by its elastic restoring force and seals and blocks the upper port of the connector body 31 as the endotracheal tube core 20 is pulled out from the upper port of the connector 30 and the intermediate opening of the elastic sealing member 32. Therefore, the sputum containing infectious virus is blocked by the blocking member 50 and cannot be splashed out, so that the environment is not polluted, the danger of possible infection by virus is not caused to medical staff, the environment pollution is less, and the safety is better. In particular, when the medical staff turns upside down the whole device with the endotracheal intubation tube core 20 pulled out to prevent the sputum containing infectious virus and the like remaining in the endotracheal intubation tube 10 from flowing out, the remaining sputum containing infectious virus and the like will not flow out through the upper port of the connector body 31 and the middle opening of the elastic sealing member 32 which are sealed and blocked by the blocking member 50, and certainly, the environment will not be polluted and the medical staff will not be at risk of being infected by the virus.
