[0002] Gastroscope is also called gastroscopy, and it is a thin and soft tube in macroscopic view. Gastroscopy is a common medical examination method, which is mainly used for observing whether there is lesion in stomach and esophagus. The current gastroscopy method can be roughly divided into ordinary gastroscopy and painless gastroscopy. No matter what kind of gastroscopy method, the gastroscope needs to be slowly inserted into the esophagus, stomach and duodenum through the patient's oral cavity and throat. During the whole gastroscopy process, the patient will feel nausea and dry heaves, and if the patient can inhale through the nose and exhale through the mouth, the nausea can be minimized. At the same time, the gastroscope will stimulate the patient's oral cavity and throat to secrete a large amount of saliva, and due to the existence of the gastroscope, the patient cannot swallow, and a large amount of saliva will flow out of the patient's mouth, resulting in that the patient's face, the bed and even the floor are full of saliva after the gastroscopy, which seriously affects the patient's image and increases the risk of cross infection in the hospital.

[0003] At present, in the existing gastroscopy process, in order to alleviate the patient's pain, the doctor will repeatedly instruct the patient to relax and inhale through the nose and exhale through the mouth, and then a disposable pad will be laid on the bed contacted by the patient's face to prevent saliva from flowing out and polluting the bed during the examination. If the patient's saliva is too much, it often drops to the floor, and there are many uncertainties in the operation, which indirectly prolongs the gastroscopy time. UTILITY MODEL CONTENT
