Automatic nutrient solution preparation device and method

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an automatic nutrient solution preparation device and method.The automatic nutrient solution preparation device comprises a device body with an opening in the upper end, a solution preparation cavity formed in the device body and a solution outlet pipe valve located at the lower end of the solution preparation cavity; the annular cover is located at the opening position of the device body, the equipment cover is movably installed in the center of the annular cover, the spiral stirrer is located in the liquid preparation cavity, an umbrella cover is arranged above blades of the spiral stirrer, and a liquid feeding mechanism, a fixed feeding assembly, a fluid pump and a driving device of the spiral stirrer are arranged at the upper end of the equipment cover. The discharging end of the liquid feeding mechanism and the discharging end of the fixed feeding assembly are each provided with a feeding pipe valve. According to the invention, automatic preparation of the nutrient solution is realized, rapid stirring is realized, large-particle solid components are stirred and dissolved rapidly after being ground, the fluid pump is used for feeding, the spiral stirrer and the umbrella cover cooperate with each other, the material mixing speed is high, and the preparation time of the nutrient solution is short.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to an automatic nutrient solution preparation device and method. Background technique [0002] The main components of enteral nutrition solution are water, maltodextrin, whey protein hydrolyzate, vegetable oil, vitamins, minerals and trace elements and other essential nutrients for human body. For patients with special periods or special needs, including diabetes, tumor patients, kidney disease or intestinal disease and other special patients, there are strict requirements for inability to eat or chew on their own, loss of swallowing function, or eating. In order to meet the nutritional needs of the body, enteral nutrition therapy is usually used to prepare enteral nutrition solution, and then use a nasogastric tube or gastroesophagus to directly deliver the enteral nutrition solution to the patient's stomach or intestine. [0003] Because the nasogastric tube an...

Problems solved by technology

At the present stage, the preparation of enteral nutrition solution is mostly made manually. Due to the complex composition of the formula during the preparation process, some nutrients, such as dietary fiber and malt paste, are very difficult to dissolve. However, the nutrition solution cannot contain large particles, resulting in The preparation process is long, and it cannot be dissolved quickly only by manpower or simple stirring equipment. At the same time, the enteral nutrient solution is a suspension, which is in an unstable state. It is prone to sedimentation after several hours. Simple stirring and shaking during use cannot quickly make it The settled particles are in a suspended state, which is generally solved by adding a thickener to the formula, but the addition of a thickener will inevitably affect the viscosity of the nutrient solution, and it is easy to stick to the tube during the delivery of the nasogastric tube and gastroesophagus, and there is also a large Dangerous; and the nutrient single stock solution is placed for too long, and it is easy to affect the shelf life of the nutrient solution. It needs to be prepared quickly, which requires a lot of manpower, so it brings work pressure and difficulty to the medical staff during the preparation process.
