Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an enteral nutrition delivery and pressure automatic regulator. Background Art

[0002] Nutrient solution infusion refers to the use of a nutrient solution infusion device to deliver nutrient solution to the patient's stomach and intestines like an infusion. In order to prevent blockage, the tube needs to be flushed during nutrient solution infusion, that is, 30 mL of flushing solution is pushed into the nutrient solution infusion device with a syringe. The flushing interval is preferably 4 hours.

[0003] At present, enteral nutrition input is mostly carried out based on experience, which cannot accurately monitor the patient's intestinal pressure and adjust the input speed according to the intestinal pressure. When flushing is required, the nutrition delivery pipeline must be unplugged first, and then the flushing pipeline must be connected for subsequent flushing. After flushing is completed, the nutrition delivery pipeline must be connected again for nutrition delivery. The operation is cumbersome and takes a long time. For this reason, we provide an enteral nutrition delivery and pressure automatic regulator to solve the above problems. Utility Model Content
