Technical Field
[0001] This utility model relates to the field of nutrient solution preparation technology, and in particular to a nutrient solution preparation device for nutrition science. Background Technology
[0002] The nutrition department is responsible for assessing and treating the nutritional needs of hospitalized patients. For postoperative patients requiring tube feeding or enteral nutrition via stoma, the nutrition department is responsible for preparing the nutritional solutions. In hospitals, some patients require tube feeding or enteral nutrition via stoma after surgery, such as after esophagectomy. However, preparing nutritional solutions is cumbersome, and patients need to use them intermittently multiple times, increasing the workload of doctors.
[0003] In typical nutrient solution mixing devices, the bottom of the tank is flat during the stirring process, making it difficult to mix the nutrient solution evenly. Furthermore, viscous nutrient solutions tend to settle at the bottom of the tank, making them difficult to clean. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a nutrient solution preparation device for nutrition science, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of this utility model provides a nutrient solution preparation device for nutrition departments, including a base, a mixing tank disposed on the top surface of the base, a motor disposed on the top surface of the mixing tank, a stirring rod disposed at the output end of the motor, a plurality of stirring blades disposed on the outside of the stirring rod, a plurality of scrapers disposed at the bottom end of the stirring rod, mixing boxes fixedly connected to both sides of the mixing tank, graduation marks disposed on the outside of both mixing boxes, a hot water tank disposed on the top surface of the base, and a first water pump disposed on the top surface of the hot water tank.
[0007] The technical effect achieved by the above solution is as follows: The materials to be mixed are poured into two mixing boxes through the feed pipe. The mixing boxes are made of transparent material so that the inside can be observed from the outside. The liquid volume can be accurately measured by setting scales. After recording the volume, the second valve is activated to allow the materials to enter the mixing tank through the feed pipe. The first water pump is activated to input hot water from the hot water tank into the outer layer of the mixing tank through the water pump pipe, which can heat the inner layer of the mixing tank. The motor is started to drive several stirring blades and scrapers to rotate, stirring the nutrient solution inside the mixing tank and breaking up any lumps in the nutrient solution. The scrapers scrape the bottom wall of the mixing tank. After stirring, the second water pump is connected to an external device, and the second water pump draws the stirred nutrient solution to the external storage device.
[0008] Preferably, in any of the above embodiments, the mixing tank has a double-layer design, a water outlet pipe is provided on one side of the mixing tank, a first valve is provided at one end of the water outlet pipe, and a second water pump is provided at the bottom of the mixing tank.
[0009] The technical effect achieved by adopting the above solution is that by inputting the hot water inside the hot water tank into the outer layer of the mixing tank, the inner layer of the mixing tank can be heated. This makes it easy to open the first valve to discharge the water with a lower temperature in the outer layer of the mixing tank, and facilitates the input of hot water.
[0010] Preferably, in any of the above embodiments, both mixing boxes are made of transparent material, both mixing boxes have a feed pipe on their top surface, and both mixing boxes have a discharge pipe at their bottom.
[0011] The technical effect achieved by adopting the above solution is that the mixing box is made of transparent material, allowing the inside to be observed from the outside. The amount of liquid can be measured accurately by setting scale marks, and the amount can be recorded.
[0012] Preferably, one end of each of the two discharge pipes is provided with a second valve, and one end of each of the two discharge pipes penetrates the interior of the inner layers on both sides of the mixing tank.
[0013] The technical effect achieved by adopting the above scheme is: starting the second valve allows the material to enter the mixing tank through the feed pipe.
[0014] Preferably, in any of the above embodiments, the hot water tank is located on the top surface of the base away from the mixing tank.
[0015] The technical effect achieved by adopting the above solution is that a gap is left between the hot water tank and the mixing tank for placing a water pumping pipe.
[0016] Preferably, in any of the above schemes, the output end of the first water pump is provided with a water pumping pipe, one end of which penetrates the interior of the outer layer of one side of the mixing tank.
[0017] The technical effect achieved by adopting the above solution is that the second water pump is connected to the external device, and the second water pump can draw the stirred nutrient solution to the external storage device.
[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0019] This device features external scales on the mixing box for easy and accurate measurement of liquid dosage. A motor drives a stirring rod, which in turn rotates several stirring blades and scrapers to agitate the nutrient solution inside the mixing tank. This also breaks down solid drugs within the nutrient solution. The scrapers scrape against the bottom wall of the mixing tank to prevent clumping and ensure more even mixing. Hot water from a hot water tank is introduced into the outer layer of the mixing tank to heat the inner layer, preventing the nutrient solution from solidifying and allowing it to dissolve quickly. This ensures smoother stirring and prevents clumping. This solution overcomes the problems of conventional nutrient solution mixing devices where the bottom of the tank is flat, making it difficult to agitate evenly and causing viscous nutrient solution to settle at the bottom, making cleaning difficult.
[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
