The one-way air valve 5 is connected to the leak-proof cuff 2 through the air supply pipe 4, and a syringe is used to inject air into the one-way air valve through the one-way air valve interface to prevent the airflow from flowing in reverse, so as to detect whether the leak-proof cuff 2 is deflated. The splash shield 3 is put on the endotracheal tube, and is close to the patient's mouth and nose during intubation. It can block the patient's splashes during the intubation process, reduce occupational exposure to medical staff, and after the intubation is completed, the patient is in an anesthetized state. The splash shield 3 is made of transparent silicone material and is flexibly connected to the tracheal body 1, so it can be directly removed without hindering the subsequent operations of medical staff. A miniature probe 10 is placed at the end of the hollow guide wire 11, which is connected to the operating handle 8 through a flexible transmission cable 7, and the operating handle 8 is connected to the visual screen 9 through a flexible transmission cable. The doctor can directly perform the intubation operation by observing the visual screen 9 through the operating handle 8, eliminating the need to insert a laryngoscope and then perform the intubation operation, thereby gaining precious rescue time for the doctor.
