Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] Such as Figure 1 to Figure 7 As shown, a gastrointestinal tube includes a main catheter 1, the front end of the main catheter 1 is a blind end 2, the rear end of the main catheter 1 is an open connection end 3, and the wall of the main catheter 1 behind the blind end 2 is provided with several The liquid outlet hole 4; the main conduit 1 accommodates a plurality of expansion bladders 5, and the plurality of expansion bladders 5 are arranged in sequence along the main conduit 1 to form a row of elongated expansion bladders 5, and the adjacent expansion bladders 5 There is a bending distance 6 between them; the expansion bag 5 is in communication wit...

Abstract

The invention discloses a gastric tube. The gastric tube comprises a primary duct, wherein the front end of the primary duct is a blind end; the rear end of the primary duct is an opening connecting end; a plurality of liquid outlet holes are formed in the wall of the primary duct at the rear part of the blind end; a plurality of expanding sacs are accommodated in the primary duct and are sequentially arrayed along the primary duct to form an entire column of strip-shaped expanding sacs; a bending space is formed between every two expanding sacs; the expanding sacs communicate with a fluid input pipe at the opening connecting end. By using the gastric tube disclosed by the invention, the hardness of the duct is controlled by adjusting the expanding degree of the expanding sacs in the duct, and further the effect of the adjusting the hardness of the duct is realized; the bending space is formed between the every two expanding sacs, so that the duct has hardness and certain elasticity, and the intubation operation of a medical worker is realized more easily.

Description

technical field [0001] The invention relates to a gastrointestinal tube. Background technique [0002] For patients who are comatose during surgery and cannot eat in the stomach, they usually use a nasogastric tube to feed the nutrient solution in clinical practice. Usually, it enters the stomach, duodenum or jejunum through the esophagus through nasal feeding. In order to facilitate insertion, the tube is required to have A certain degree of hardness and elasticity should not be discounted. Clinically, doctors often spend time on the insertion of the catheter, especially for patients who enter the duodenum, it is difficult for the catheter to pass through the pylorus. The prior art urgently needs a gastrointestinal tube with reasonable design and easy intubation. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a gastrointestinal tube with reasonable design and easy intubation. [0004] In o...
