Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically to a gastric tube for digestive medicine. Background Art

[0002] Gastroenterology is an important part of internal medicine and an indispensable branch of internal medicine. Gastroenterology is a clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Commonly used tools in gastroenterology include gastric tubes, which are medical devices mainly used for nasogastric feeding. They are inserted through the nostrils, through the pharynx, into the esophagus and into the stomach. In addition to being used to extract gastric juice, they can also be used to inject nutrient fluids into the patient's stomach to keep the patient nourished and maintain their vital signs.

[0003] Gastric tubes generally need to be replaced in about one to two weeks. If the gastric tubes are not replaced for a long time, it is easy to cause problems such as nasal mucosal pain or pressure ulcers. When replacing the gastric tubes, the patients need to endure the painful feeling of inserting the gastric tubes again. Therefore, in response to such problems, a gastric tube for gastroenterology is proposed to solve the occurrence of such problems. Utility Model Content
