Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel connecting device for a three - lumen jejunal feeding tube of a jejunal nutrition tube. Background Technique

[0002] The three - lumen jejunal nutrition tube is a special feeding tube designed for enteral feeding, diagnosis, treatment and monitoring of critically ill patients. It is applicable to patients with gastric paralysis / gastric emptying disorder, pyloric stenosis, etc. In addition to enteral nutrition treatment, this product can also be used for gastric juice drainage, determination of gastric juice pH value, early diagnosis and treatment of gastric bleeding in critically ill patients. It is a feeding tube with three channels, namely a feeding channel, a suction channel, and a pressure - regulating channel. The feeding tube can be inserted through the nose. The end of the feeding channel can reach the jejunum for enteral nutrient feeding, the end of the suction channel can reach the stomach for gastric decompression; the end of the pressure - regulating channel can reach the stomach for pressure control during gastric decompression.

[0003] When using the feeding channel for continuous enteral nutrition supplementation, a gastrointestinal nutrition bag and a gastrointestinal pump are usually used. During the use process, the conical connecting section end of the original extension tube of the three - lumen jejunal nutrition tube needs to be connected to the conical interface of the gastrointestinal nutrition bag, and the outlet end is inserted into the feeding end of the three - lumen jejunal nutrition tube for continuous nutrition supplementation through the use of a gastrointestinal pump; when it is necessary to administer drugs or flush the jejunal nutrition tube, the extension tube needs to be disconnected from the feeding end of the three - lumen jejunal nutrition tube, the syringe is connected to the Luer connector, and the other end of the Luer connector is connected to the feeding end of the three - lumen jejunal nutrition tube for drug administration or flushing.

[0004] During the process of using the extension tube for enteral nutrition support through the three - lumen jejunal nutrition tube, when it is necessary to administer drugs or flush the pipeline to the patient through the feeding end, it is necessary to first disconnect the extension tube from the feeding - end interface, secondly connect the syringe to the Luer connector, and finally connect the other end of the Luer connector to the feeding end for drug administration or flushing. This process requires repeated connection and disconnection of the extension tube and the feeding - end interface, which is likely to damage the extension tube, and artificially increases the probability of contamination of enteral nutrition preparations, increasing the clinical workload and being inconvenient for clinical operation.

[0005] Therefore, it is necessary to provide a novel connecting device for a three - lumen jejunal nutrition tube feeding tube to solve the above - mentioned technical problems. Content of the Utility Model

[0006] The utility model provides a novel connecting device for a three - lumen jejunal nutrition tube feeding tube, which solves the problems of repeated connection and disconnection of the extension tube and the feeding - end interface, easy damage to the tube body, increased infection probability and increased workload.
