Gastric tube is widely used in the medical and surgical diagnosis and treatment of gastrointestinal diseases, and plays an important role in gastrointestinal surgical treatment such as gastrointestinal decompression, gastrointestinal drainage and enteral nutrition. At present, the gastric tubes used clinically are generally made of single-lumen silicone tubes without any fixing measures. They are only pasted with facial skin adhesive tape. If the patient's gag reflex is strong, it is easy to come out; and the single-tube single-lumen structure of ordinary gastric tubes is not only easy to block , The clinical drainage effect is not good enough, often causing certain complications to clinical treatment. In order to solve the above problems, researchers are committed to developing a gastric tube that can prevent slippage, such as the utility model patent double-balloon gastric tube with application number 200920240483.7, the utility model patent gastric tube with application number 201120511121.4, and the patented gastric tube with application number 200620080514.3 The utility model patent balloon gastric tube and the utility model patent disposable balloon gastric tube with application number 201020552961.0 are not limited to the gastric tube described in the above patent application, although they all use the balloon anchoring technology to fix the position of the gastric tube, However, this kind of gastric tube with air bag cannot give full play to the effect of the air bag to achieve the effect of local hemostasis. Because the bleeding position in the stomach is uncertain, these gastric tubes with air bag cannot freely adjust the position of the air bag on it, so that the air bag cannot be positioned To the designated place to achieve the effect of hemostasis. In addition, in the past, during the use of gastric tubes, especially indwelling gastric tubes, after feeding the patient through the gastric tube, it is necessary to wash the gastric tube with saline. In this process, the number of times of washing and the amount of saline used The reason is that the amount of saline flushed is affected by the capacity of the patient's stomach. the
