Easily separated multi-cavity gastrointestinal tube

Abstract

The invention provides an easily separated multi-cavity gastrointestinal tube. The gastric tube comprises a gastric tube, an intestinal nutritional tube partially arranged in the gastric tube, a guide wire and a connector, wherein the far end of the gastric tube and the intestinal nutritional tube are connected with an easy separation device through a mechanical connector; the far end of the gastric tube is coated by the outer surface of the intestinal nutritional tube, and the far end of the intestinal nutritional tube extends outside the far end of the gastric tube; the guide wire is inserted into the intestinal nutritional tube through the connector; and the mechanical connector and the easy separation device are operated to separate the far end of the gastric tube and the outer surface of the intestinal nutritional tube. After the easily separated multi-cavity gastrointestinal tube is implanted into stomach and intestine of a patient, the gastric tube and the intestinal nutritional tube can be separated by operation of a user, and the gastric tube and the intestinal nutritional tube can be respectively removed, so that the operability can be improved, and pains of the patient can be relieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an easily separable multi-lumen gastrointestinal tube. Background technique [0002] In medical work, it is often encountered that patients need gastrointestinal drainage, decompression and enteral nutrition supply to support treatment, as well as physical recovery after surgery. Usually, a gastrointestinal tube is inserted through the nasal cavity and extended into the stomach and small intestine for gastrointestinal drainage, decompression, irrigation, nutrition and / or enteral nutrition supply. [0003] In the prior art, there have been double-lumen gastrointestinal tubes, which can supply gastrointestinal decompression and enteral nutrition at the same time, but the gastric tube and enteral nutrition tube are not easy to separate. When gastrointestinal decompression is completed or no gastrointestinal decompression is required , the gastric tube cannot be evacuated alone. Due t...

Problems solved by technology

[0003] In the prior art, there have been double-lumen gastrointestinal tubes, which can supply gastrointestinal decompression and enteral nutrition at the same time, but the gastric tube and enteral nutrition tube are not easy to separate. When gastrointestinal decompression is completed or no gastrointestinal decompression is required , the gastric tube cannot be evacuated alone. Due to the thick diameter of the gastric tube, if it is placed in the gastrointestinal tract through the nasal cavity for a long time (enteral nutrition supply is often a long-term process, even ten months), the patient has poor tolerance and needs to bear it. prolonged and severe pain

Therefore, this double-lumen gastrointestinal tube cannot be applied clinically.

[0004] Moreover, when the end of the enteral nutrition tube of the double-lumen gastrointestinal tube passes through the guide wire to enter the small intestine through the gastric pylorus, the operation technology and equipment are quite demanding, and it is difficult for existing devices to do this.
