Technical Field

[0001] The utility model relates to the technical field of nutrient solution feeding, in particular to a nutrient solution feeding device. Background Art

[0002] At present, under normal circumstances, the nutritional solutions that can supplement physical energy include glucose injection, compound amino acid injection, fat emulsion injection, multivitamin injection, and water-soluble vitamins for injection. Patients are advised to choose the appropriate nutritional solution according to their specific circumstances. Nutritional solution means infusion of nutritional solution. Generally, those who cannot eat orally, those who are severely malnourished, those with severe intestinal malabsorption or inability to absorb, and those with advanced malignant tumors need to be infused with nutritional solution.

[0003] When using nutrient solution, the nutrient solution will be slowly injected into the stomach through a syringe, about 200 ml each time, and given 6-8 times a day. This method is suitable for giving homogenized diets and can be given through a nasogastric tube, but it is not suitable for giving through a nasointestinal tube. Although this method may cause abdominal distension, diarrhea, vomiting and other discomforts in some patients, after a few days of adaptation, most patients can gradually tolerate it.

[0004] This injection method not only requires nurses to perform the operation repeatedly, which is time-consuming and laborious, but also makes it difficult to control the temperature of the nutrient solution. Nutrient solution with a low temperature may cause adverse reactions in patients. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

Solenoid valves are installed on the suction pipe and the suction pipe to control the internal flow of the suction pipe and the suction pipe.

[0011] As an optional solution to the technical solution of the present application, a placement groove is provided at the bottom of one side of the shell, and piston holes are provided at both ends of the bottom side of the placement groove. Piston rods are movably installed in two groups of the piston holes, and extrusion plates are fixedly installed on the top of the two groups of piston rods.
