Internal fixation stomach tube capable of preventing regurgitation and aspiration

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an internal fixation stomach tube capable of preventing regurgitation and aspiration, which comprises a stomach tube main body, the stomach tube main body is provided with an outflow port, an air bag, an air delivery tube and a liquid scraping ring, and the liquid scraping ring is provided with a connecting rope. A food injection connector is arranged at one end of the stomach tube body, a connecting piece is arranged on one side of the food injection connector, a plug cap is arranged on the connecting piece, a conveying cavity is formed in the stomach tube body, an air conveying cavity is formed in the stomach tube body, and an anti-sticking layer is laid on the inner wall of the conveying cavity. The internal fixation stomach tube is provided with the air bag, pressure is applied to the inner wall of the esophagus through the expansion pressure of the air bag, so that the effect of internally fixing the stomach tube is achieved, the fixing effect is good, the non-planned tube drawing phenomenon can be reduced, meanwhile, the air bag blocks the esophagus, and regurgitation and aspiration of gastric contents are prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an internally fixed gastric tube for preventing reflux and aspiration. Background technique [0002] According to the seventh census of China in 2020, the number of elderly people aged ≥ 60 in China is 264 million, accounting for 18.70% of the total population. Decreased stress ability, and accompanied by various acute and chronic diseases, the most common is anemia and decreased immune function caused by malnutrition in the elderly. Nutritional support, the use rate of gastric tube is about 30%, so the safety and reliability of gastric tube use is a matter of widespread concern; at present, during the use of gastric tube in elderly patients, aspiration reflux (especially invisible aspiration) occurs. ) and unplanned extubation are more common. Aspiration refers to the condition that patients cannot swallow normally and inhale the contents of the mouth or stomach under t...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides an internally fixed gastric tube to prevent reflux and aspiration, which solves the need to extract the gastric tube from the patient's body when the use time of the existing gastric tube reaches the upper limit. There will be a lot of saliva on the gastric tube, which will cause inconvenience to the medical staff. When delivering liquid food, liquid food residue will remain on the inner wall of the gastric tube. If the residue stays for a long time, it will affect the quality of liquid food delivered later.
