Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the inventive solutions, the technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention.

[0020] like Figure 1-5 As shown, a retrograde gastric tube includes a gastric tube body 1 , a jejunum feeding tube 2 and a dilation balloon tube body 3 . The stomach tube body 1 can be inserted into the stomach through the jejunostomy stoma, the jejunum nutrition tube 2 is connected to the stomach tube body 1, the jejunum nutrition tube 2 can be inserted into the jejunum, and the expansion balloon tube body 3 is connected to the stomach tube body 1 On the top, an expansion sac 31 that can be expanded and fixed at the jejunostomy stoma is formed on the expansion sac body 3 .

[0021] Specifically, a first channel 21 is formed in the jejunum nutrition tube 2 , and the jejunum nutrition tube 2 can deliver n...

Abstract

The invention discloses a retrograde gastric tube comprising a gastric tube body which can be inserted into the stomach through a jejunum ostomy opening, a jejunum nutrition tube which can be inserted into the jejunum, and an expander capsule tube body. An expander capsule which can be expanded and fixed at the jejunum ostomy opening is formed on the expander capsule tube body. A first channel through which nutrient solution can be transmitted to the jejunum is formed in the jejunum nutrition tube, and a second channel through which liquid can be transmitted to the expander capsule is formed in the expander capsule tube body. A main channel allowing liquid to flow out and an auxiliary channel allowing the jejunum nutrition tube to movably pass through are formed in the gastric tube body, the main channel and the auxiliary channel are arranged in parallel, and the side wall of the gastric tube body is provided with holes which are communicated with the auxiliary channel and allow the two ends of the jejunum nutrition tube to go out. The expander capsule tube body sleeves the gastric tube body. The jejunum nutrition tube is fixed to the gastric tube body through a fixing buckle. Stimulation and damage of the retrograde gastric tube to nasal mucosa during installation can be avoided, and patients' pain can be relieved; and the jejunum nutrition tube can be assembled and disassembled, so that the retrograde gastric tube is more flexible in use.

Description

technical field [0001] The invention relates to a gastric tube, in particular to a retrograde gastric tube, belonging to the technical field of medical devices. Background technique [0002] At present, the known gastric tube is a flexible pipe, the head is a sealing rubber stopper, and the tail has side holes. The gastric tube is inserted through the nostril and reaches the stomach through the esophagus through the pharynx. It is mostly used for gastrointestinal decompression, enteral nutrition input or treatment of gastrointestinal bleeding. Clinically, after resection of malignant tumors such as esophageal cancer, a nasogastric decompression tube and a jejunal nutrition tube need to be routinely placed. Nasal intubation can cause irritation and damage to the nasal mucosa, and intubation narrows the esophagus, making it easier to cause obstruction and inflammation, which will affect the quality of life of patients, postoperative recovery and even disease prognosis.
