Description

Technical Field

[0001] This utility model relates to the field of nutrient solution configurator technology, specifically a nutrient solution configurator. Background Technology

[0002] As is well known, artificial enteral nutrition solutions are mixtures of various nutrients. Typically, glucose, fat, amino acids, vitamins, electrolytes, and trace elements are mixed in specific proportions according to the patient's physiological needs to form a liquid, which is then administered to patients in the recovery period to provide nutritional support and sustain life. Clinically, enteral nutrition solutions are commonly used to treat digestive tract diseases. Hospital gastroenterology departments have a huge demand for these solutions, requiring timely preparation and replenishment. However, current technology for preparing enteral nutrition solutions is limited and warrants further research.

[0003] Utility model CN208583249U discloses an enteral nutrition solution preparation device, including a tank, a stirring assembly, and a weighing cylinder. This utility model provides an enteral nutrition solution preparation device that uses a weighing cylinder to control the feeding ratio, making it convenient and quick. A stepper motor drives a rotating shaft, and by controlling the stepper motor speed, the magnitude of the centrifugal force on the stirring rod is changed. The stirring rod, under a large centrifugal force, deflects outward and acts on a sliding block via a telescopic rod, causing the sliding block to move and deform a spring. Since the centrifugal force is positively correlated with the stepper motor speed, when the speed decreases, the sliding block, under the combined action of the spring's restoring force, gravity, and centrifugal force, causes the corresponding stirring rod to deflect inward again. This achieves automatic changes in the stirring rod's deflection angle, coordinating with the rotation to stir within the tank, improving turbulence, avoiding dead zones, and ensuring uniform mixing.

[0004] The rotating shaft, turntable, rotating seat, support spring, tension spring, moving nut, telescopic rod, and stirring rod in the above-mentioned device are all located inside the tank, making it inconvenient to clean after the device is used.

[0005] To address the above problems, this utility model provides a nutrient solution preparer. Utility Model Content
