Double sets of nasogastric tube with external drainage of irrigating fluid and its drainage irrigation method

Abstract

The invention discloses a double-set nasogastric tube capable of draining flushing liquid, and relates to a structure of the nasogastric tube. It includes a gastric tube body, an outer sleeve, an inner sleeve, a first through hole, a second through hole and a third through hole; the drainage tube is fixed on the outer front end of the outer sleeve; the front end of the inner sleeve and the front end of the outer sleeve are both It is a blind end, and the tail end of the inner sleeve is connected with an anti-pollution cover that seals the tail end of the inner sleeve; the tail end of the inner sleeve and the tail end of the drainage tube are both tapered and enlarged, and The tail end of the inner casing is connected with the first external device, and the tail end of the drainage tube is connected with the second external device; the tail end of the inner casing or the tail end of the outer casing is provided with nasal feeding fluid injection marks and flushing fluid drainage marks. The invention has the advantages of simple structure and convenient operation, which not only allows the flushing liquid to flush the pipeline of the nasogastric tube, but also prevents the flushing liquid and the nutrient solution (or medicine) from being poured into the patient's body together. The invention also relates to a method for drainage and perfusion of the double-set nasogastric tube that can be used for external drainage of irrigating fluid.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and appliances, and in particular relates to a structure of a nasogastric tube, more specifically a double-set nasogastric tube capable of external drainage of flushing liquid. The invention also relates to a method for drainage and perfusion of the double-set nasogastric tube that can be used for external drainage of irrigating fluid. Background technique [0002] The use of nasogastric tubes to perfuse nutrient solutions (or medicines) in patients' stomachs has been widely used clinically. (gastric tube body) to flush the pipeline to prevent the inside of the pipeline from being blocked. In the prior art, when the patient is flushed through a nasogastric tube, the flushing liquid and the nutrient solution (or medicine) will be poured into the patient's body together, which will cause local discomfort to the patient and allow the patient to take in excess water into the body. , so i...
