Stomach tube and nutrition tube integrated multifunctional pipeline structure for thoracic department

Abstract

The invention discloses a stomach tube and nutrition tube integrated multifunctional pipeline structure for the thoracic department, and particularly relates to the field of the thoracication.The stomach tube and nutrition tube integrated multifunctional pipeline structure comprises a catheter, an air bag is arranged on the outer surface of the catheter, and a buffer tube is arranged on the portion, located above the air bag, of the outer surface of the catheter. When a nutrient solution or normal saline is injected, one end of an injector is connected with the butt joint pipe at one end of the top cover, the top cover is screwed into one end of the connector, the connector is in threaded connection with the top cover, in the screwing-in process, the inner ring pushes the inner plug to open the through hole in the outer surface of the inner pipe, after conveying is completed, the top cover is rotated, the top cover is slowly taken out, and the connector is screwed into the connector. In the process that the top cover is separated from the connector, the spring pushes the inner plug upwards, and after the top cover is completely separated from the connector, the inner plug closes the through hole in the surface of the inner tube, so that air is prevented from entering and polluting the catheter, meanwhile, the difficulty of cleaning the stomach tube is reduced, the service life of the stomach tube is prolonged, and the stomach tube is practical.

Description

technical field [0001] The embodiments of the present invention relate to the field of thoracic surgery, and in particular to an integrated multifunctional pipeline structure of gastric tube nutrition tube for thoracic surgery. Background technique [0002] The gastric tube reaches the stomach from the pharynx through the esophagus. It is mostly used to pump gastric juice. It is used for gastric lavage in acute poisoning, and it can also be used to inject liquid into the stomach to provide the patient with necessary food and nutrition. Care should be taken to avoid gastric tube Contamination, and prolapse of gastric tube, leading to aspiration. [0003] The prior art has the following deficiencies: after the nutrient solution or saline is delivered through the gastric tube, one end of the gastric tube needs to be blocked by a stopper immediately to avoid contamination of the gastric tube, but no matter how quickly one end of the gastric tube needs to be blocked , there will...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides an integrated multi-functional pipeline structure of gastric tube nutrition tube for chest department. Through the joint, spring, inner plug and buffer tube, when injecting nutrient solution or physiological saline, the syringe's One end is connected to the butt pipe at one end of the top cover, the top cover is screwed into one end of the joint, and the joint is threaded with the top cover. During the screwing process, the inner ring pushes the inner plug to open the through hole on the outer surface of the inner tube. When the delivery is completed, turn the top cover and slowly take out the top cover. During the process of the top cover being separated from the joint, the spring will push the inner plug upward. When the top cover is completely separated from the joint, the inner plug will also push the inner tube surface The through hole is closed to prevent air from polluting the catheter, and at the same time reduce the difficulty of cleaning the gastric tube and increase the service life of the gastric tube. It is more practical and solves the problem of the prior art that the gastric tube is easily polluted
