[0002] A gastrointestinal tube (also known as a gastric tube, intestinal tube or gastrointestinal catheter) is a medical device used to deliver or drain substances into the gastrointestinal tract. The gastrointestinal tube is usually inserted through the nasal cavity or oral cavity into the stomach, or through the stomach wall into the intestinal tract. It has a very wide range of applications and is commonly used in various medical scenarios that require the delivery of liquids, drugs or nutrients through the gastrointestinal tract.

[0003] According to a multifunctional gastrointestinal cannula (publication number: CN 220089994U) disclosed in the prior art, the multifunctional gastrointestinal cannula comprises a gastric tube and a duodenal tube arranged in the gastric tube, wherein a first adjusting port is arranged on the side wall of the gastric tube, the duodenal tube enters the gastric tube from the first adjusting port and extends linearly along the axial direction of the gastric tube. Through the above improvement, since the duodenal tube is pre-inserted into the gastric tube, the multifunctional gastrointestinal cannula of the utility model can shorten the catheterization time during surgery, facilitate postoperative care, reduce the discomfort of patients, avoid related complications, and improve the postoperative compliance of patients, which is quite beneficial to postoperative recovery.

[0004] In the above-mentioned application, the duodenal tube and the first adjusting port assembly cooperate with each other, but cannot fix the gastrointestinal tube after it is inserted into the nasal cavity of the patient. The traditional fixing method cannot adjust the size of the nasal plug according to the size of the patient's nasal cavity, which affects the use. Therefore, we propose a gastrointestinal cannula.
