Nutrient canal of intestine for reducing pressure of stomach

Abstract

The invention relates to a gastric decompression intestinal nutrition tube, which includes: a gastric tube, and the upper end of the gastric tube is provided with a multi-way connector; the upper end of the multi-way connector is the entrance of the gastric tube, and a first side end of the multi-way connector is a gastric decompression orifice, and an adjustable fixed ring and a gastric tube ball bag are respectively arranged on the gastric tube from top to bottom; a gas / water one-way valve is arranged on a second side end of the multi-way connector, and a ball bag gas / water inlet is arranged on the gastric tube in the gastric tube ball bag, wherein the gas / water one-way valve is connected with the ball bag gas / water inlet by a gastric tube ball bag gas / water tube; an intestinal nutrition tube which is inserted in the gastric tube from the entrance of the gastric tube and has the length which is longer than that of the gastric tube is assembled in the gastric tube. The intestinal nutrition tube and the gastric tube are detachable and can be used in combination, and the length of the gastric tube and / or the intestinal nutrition tube can be cut during specific clinical use to meet the requirements of different cases.

Description

technical field [0001] The invention relates to a gastric decompression enteral nutrition tube for performing enteral nutrition and gastric decompression through gastrostomy in the technical field of medical instruments. Background technique [0002] In the prior art, when performing an esophagus or gastrectomy operation, it is necessary to insert a nutrition tube into the small intestine and leave it for several days. Chinese Patent Publication No. CN1076125 discloses a "three-cavity feeding tube", which can simultaneously perform gastric decompression and intestinal feeding, but because it is inserted from the nasal cavity, the patient's tolerance is poor, and the alar fixation effect is poor (easy to slip off or inhale) ), patients with severe lung disease or esophageal disease cannot use it, etc. [0003] US Patent No. 5,458,583 discloses a catheter for gastrostomy. The disadvantage of this device is that the device is only used for gastric nutrition and cannot perform ...

Problems solved by technology

Chinese Patent Publication No. CN1076125 discloses a "three-cavity feeding tube", which can simultaneously perform gastric decompression and intestinal feeding, but because it is inserted from the nasal cavity, the patient's tolerance is poor, and the alar fixation effect is poor (easy to slip off or inhale) ), patients with severe lung disease or esophageal disease cannot use it, etc.

[0003] U.S. patent document US5458583 discloses a catheter for gastrostomy. The disadvantage of this device is that the device is only used for gastric nutrition and cannot perform enteral nutrition.

The disadvantage of the gastrointestinal feeding tube is that the disclosed gastrointestinal feeding tube has a single function, and the intestinal tube and gastric tube cannot be disassembled or combined arbitrarily, and the flexibility is poor, which is not conducive to emergency use in clinical practice
