In summary, the utility model has the following advantages:

1. The improved oropharyngeal ventilation tube can be inserted into a sputum suction tube through a V-shaped opening on the anti-ingestion plate to clean up oral secretions. The incisors are stuck in the occlusal grooves of the incisors, and the fixed belt is used together to prevent the ventilation tube from falling off.

2. The improved oropharyngeal ventilation tube is easy to use and easy to fix. It is equipped with an oxygen tube and a solution tube, which can input oxygen and anesthesia solution, which greatly reduces the pain of the patient. At the same time, it is equipped with a timer to facilitate the regular care of the patient. .
