[Design and application of a new gastrointestinal nutrition pipeline]

Gastrointestinal nutrition tube is a special gastrointestinal tube designed for enteral nutrition, diagnosis, treatment and monitoring in severe patients. Clinically, it is inserted into patients' stomach for flushing, provide nutrition through stomach, duodenum or jejunum, and decompress gastrointestinal tract. It also can be used for gastric drainage, gastric juice pH value determination, and early diagnosis and treatment for stomach bleeding and other symptoms. Currently, gastrointestinal nutrition tube can only rely on guidewire and blind manipulation, or by gastroscopy, which may produce damage to the patients, including stimulating the digestive tract mucous membrane, and causing adverse reaction. Therefore, a new type gastrointestinal nutrition line was designed by the medical staff of intensive care unit (ICU) of the First People's Hospital of Fuyang District in Hangzhou according to the technical problems existing in the insertion of gastrointestinal nutrition tube, and National Utility Model Patent of China was obtained (ZL 2019 2 0118506.0). It included V-shaped joint, first pipe, second pipe, function module, supply pipe, scale line, upper clasp, lower clasp, elliptical balloon, elastic guide wire and infusion opening. Compared with the existed technology, it has multiple channels, functions and placement methods. The utility model has a simple structure and reasonable design, which can be very handy to insert and provide nutrient solution.
