[0002] A gastrointestinal nutrition tube is a gastrointestinal tube specially used for enteral nutrition, treatment or monitoring of patients with advanced gastric tumors, severe pancreatitis, etc.

[0003] The main function of the gastrointestinal nutrition tube is to deliver necessary water and food, as well as drain the accumulated fluid and gas in the stomach during gastrointestinal decompression. Currently, both gastric tubes and intestinal tubes are usually inserted at the same time in clinical practice. The intestinal tube focuses on the nasogastric feeding function, which directly reaches the intestine so that its nutrients do not pass through the stomach cavity to provide enteral nutrition. The gastric tube has both drainage and decompression. However, the simultaneous insertion of a gastric tube and an intestinal tube in the nasal cavity causes the patient's nasal cavity to become blocked and uncomfortable. Most patients find it difficult to tolerate greater stimulation. Patients with poor self-control may pull out the intestinal and gastric tubes by themselves, affecting subsequent treatment. At the same time, due to nasal discomfort, patients often scratch, causing the intestinal or gastric tube to shift and lose their original function.

[0004] Therefore, those skilled in the art are committed to developing a gastrointestinal nutrient tube to reduce the pain and discomfort caused by the gastrointestinal tube to the nasal cavity and pharynx, and to facilitate the fixation of the nutrient tube. Utility Model Content
