Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an injectable enteral nutrition tube. Background Technique

[0002] An enteral nutrition tube is a catheter pre-placed in the gastrointestinal tract, through which enteral nutrient solution is injected into the gastrointestinal tract. When injecting nutrient solution into the intestine in the early postoperative period, there is a risk of increasing the intestinal pressure. Excessive intestinal pressure may cause the anastomotic stoma to rupture. Therefore, it is necessary to continuously innovate the function of the enteral nutrition tube. After retrieval, an enteral nutrition tube disclosed in the application number CN202121417588.2 includes a nutrition tube body and a feeding tube. When injecting nutrient solution into the feeding tube, the nutrient solution can flow into the feeding tube through the anti-backflow valve and flow out from the exposed end of the nutrition tube body; the middle section of the feeding tube is a color-changing tube, and heat-sensitive materials that can change color are dispersedly embedded in the color-changing tube. The heat-sensitive materials can change color when the temperature is above 40°C. This enteral nutrition tube can not only prevent the backflow of nutrient solution, but also master the temperature of the nutrient solution, thereby preventing the nutrient solution from scalding people due to excessive temperature, and then improving the comfort and safety of use. However, the above description still has the following defects in actual use: The current enteral nutrition tube sends the nutrient solution into the gastrointestinal tract of the patient. After the injection is completed, it is not convenient to clean the inside of the tube body, resulting in residual liquid on the inner wall of the tube. But during this process, the separation of the structure allows air to enter the pipeline and then into the patient's body, causing discomfort. Therefore, it is necessary to design an injectable enteral nutrition tube with strong practicability. Content of the Utility Model
