Double-sleeve nasogastric tube allowing outward drainage of irrigating fluid and drainage and injecting method thereof

Abstract

The invention discloses a double-sleeve nasogastric tube allowing outward drainage of irrigating fluid and relates to a nasogastric tube structure. The double-sleeve nasogastric tube comprises a nasogastric tube body, an outer sleeve, an inner sleeve, a first through hole, a second through hole and a third through hole; a drainage tube is fixed to the front end of the outside of the outer sleeve; both the front end of the inner sleeve and the front end of the outer sleeve are blind ends, the tail end of the inner sleeve is connected with an anti-pollution cover which seals the tail end of the inner sleeve; both the tail end of the inner sleeve and the tail end of the drainage tube are conical and expanded, the tail end of the inner sleeve is connected with a first external device, and the tail end of the drainage tube is connected with a second external device; the tail end of the inner sleeve or the tail end of the outer sleeve is provided with a nasal fluid injection marker and an irrigating fluid drainage marker. The double-sleeve nasogastric tube is simple in structure and convenient to operate, enables the irrigating fluid to irrigate a passage of the nasogastric tube and can prevent the irrigating fluid and nutrient fluid (or medicine) to be injected together into the body of a patient. The invention also relates to a drainage and injecting method of the double-sleeve nasogastric tube allowing outward drainage of irrigating fluid.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment and appliances, and specifically relates to a structure of a nasogastric tube, and more specifically, a double-set nasogastric tube with external drainage of flushing liquid. The invention also relates to a method for drainage and perfusion of the double-set nasogastric tube capable of external drainage of the flushing liquid. Background technique [0002] The use of nasogastric tube to infuse the patient’s stomach with nutrient solution (or medicine) has been widely used in clinical practice. Every time after the patient is filled with nutrient solution (or medicine) through the nasogastric tube, people also need to use the nasogastric tube. (The gastric tube body) is flushed to prevent the inside of the tube from being blocked. In the prior art, when the patient is flushed through the nasogastric tube, the flushing liquid and the nutrient solution (or medicine) will be poured into the pati...
