At this time, the spring 243 is compressed, and the scraper plate 247 contacts the bottom of the inner wall of the proportioning tank 21. Driven by the drive motor 244, the nutrient solution remaining at the bottom of the inner wall of the proportioning tank 21 is scraped into the pipeline for easy discharge into the infusion tank 42.
[0041] Please refer to the attached Figure 2 、 4 , 6, and 8, in another preferred embodiment of the present invention, the nutrient solution flow control transmission device 40 includes a support ring 41 whose bottom end is connected to the top of the top plate 12, an infusion tank 42 provided on the inner wall of the support ring 41 and the top of the side wall is connected to the bottom of the proportioning tank 21 through a pipeline, a funnel tube 43 connected to the bottom of the infusion tank 42, a stirring infusion component 44 provided on the top of the infusion tank 42 and with the execution end extending into the funnel tube 43, a flow control component 45 provided at the bottom of the funnel tube 43, and a flow control component 45 provided at the bottom of the flow control component 45. The switching component 46 is located at the top of the top plate 12, and a plurality of intake tubes 47 are provided at the execution end of the switching component 46.

[0042] It should be noted that, in this embodiment, after the nutrient solution enters the infusion tank 42, the controller receives temperature data from the temperature sensor 483 and triggers the heater 482 until the temperature data reaches a set value. The appropriate intake tube 47 is switched to the infusion state through the switching component 46 to facilitate nasogastric feeding, enteral feeding or intravenous injection. After the adjustment is completed, the second electrically controlled valve 452 is opened and the stepping motor 441 is started. The stepping motor 441 drives the screw rod 442 and the extension rod 443 to rotate, and the screw rod 442 drives the plunger plate 445 to descend, so that the nutrient solution is discharged through the funnel tube 43, the flow control tube 451, the transmission through hole 463 and the intake tube 47. When the nutrient solution passes through the funnel tube 43, the extension rod 443 drives the stirring rod 444 to stir the nutrient solution for a second time.
[0043] Furthermore, the controller receives flow data from the flow sensor 453 and changes the speed of the stepper motor 441 until the flow data reaches a set value;
[0044] Furthermore, when the switching component 46 is working, the switching dial 462 is rotated until the appropriate transmission through hole 463 is connected to the flow control tube 451 .
[0045] The specific process of the present invention is as follows:
[0046] The controller model is "MTCX2", the flow sensor 453 model is "LWGY-FMT", and the temperature sensor 483 model is "DS18B20".
[0047] When the nutrient solution is taken in, the medical staff measures and mixes the various nutrient solution components through the nutrient solution proportioning device 20 to prepare a nutrient solution suitable for the patient. The prepared nutrient solution is discharged into the nutrient solution flow control transmission device 40 and is taken into the patient's body through the nutrient solution flow control transmission device 40. When the nutrient solution is not used up, the valve on the pipeline connecting the storage box 31 and the funnel tube 43 is opened, and the second electric control valve 452 is closed. At this time, the nutrient solution enters the storage box 31, and the refrigeration system connected to the evaporator 32 starts to work to cool the nutrient solution for storage. When it needs to be used again, the air pressure source pipe 33 is used to pressurize the storage box 31, and the nutrient solution in the storage box 31 re-enters the nutrient solution flow control transmission device 40, and can be reheated and stirred. After heating and stirring, it is injected into the patient's body;
[0048] When proportioning the nutrient solution, the medical staff adds different nutrient solution components into the multiple measuring tanks 222 respectively. The quantitative addition can be carried out through the transparent scale plate on the side wall of the measuring tank 222. After the addition is completed, the top cover 231 is covered on the top of the measuring tank 222. The medical staff controls the opening order of the multiple first electrically controlled valves 223 through the controller to meet the addition order requirements when proportioning the nutrient solution components. After the first electrically controlled valves 223 are opened, the nutrient solution components enter the proportioning tank 21 through the feed pipe 221. At this time, the driving motor 244 drives the shaft 245 to rotate, and the stirring rod 246 and the scraper 247 stir and mix the various nutrient solution components.
[0049] The air source pipe 234 can be connected to the air source, and the air flow is discharged through the air flow cavity 232 and the air injection hole 233 to blow the nutrient solution components attached to the inner wall of the measuring tank 222 into the proportioning tank 21, and the air flow is discharged through the exhaust valve at the top of the proportioning tank 21;
[0050] After the stirring is completed, the valve at the bottom of the mixing tank 21 is opened, and the nutrient solution enters the infusion tank 42 through the pipeline. At this time, the medical staff can press the pressure rod 253 downward, and the scraper ring 252 separates from the magnetic ring 251. The scraper ring 252 scrapes the nutrient solution attached to the side wall of the mixing tank 21 to the bottom of the mixing tank 21. After the top of the pressure rod 253 contacts the base plate 241, the pressure rod 253 is further pressed downward. At this time, the spring 243 is compressed, and the scraper plate 247 contacts the bottom of the inner wall of the mixing tank 21. Driven by the drive motor 244, the nutrient solution remaining at the bottom of the inner wall of the mixing tank 21 is scraped into the pipeline for easy discharge into the infusion tank 42.
[0051] After the nutrient solution enters the infusion tank 42, the controller receives temperature data from the temperature sensor 483 and triggers the heater 482 until the temperature data reaches the set value. The appropriate intake tube 47 is switched to the infusion state through the switching component 46 to facilitate nasogastric feeding, enteral feeding or intravenous injection. After the adjustment is completed, the second electrically controlled valve 452 is opened and the stepper motor 441 is started. The stepper motor 441 drives the screw rod 442 and the extension rod 443 to rotate. The screw rod 442 drives the plunger plate 445 to descend, so that the nutrient solution is discharged through the funnel tube 43, the flow control tube 451, the transmission through hole 463 and the intake tube 47. When the nutrient solution passes through the funnel tube 43, the extension rod 443 drives the stirring rod 444 to stir the nutrient solution for a second time.
[0052] The controller receives the flow data from the flow sensor 453 and changes the speed of the stepper motor 441 until the flow data reaches the set value;
[0053] When the switching component 46 is working, the switching dial 462 is rotated until the appropriate transmission through hole 463 is connected to the flow control tube 451.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
