[0030] Reference Figure 2 The crushing mechanism includes a filter plate 10 and filter holes 11. A plurality of filter holes 11 are arranged on the surface of the filter plate 10. A crushing scraper 12 is arranged above the filter plate 10. The filter plate 10 is fixedly connected to the inner wall of the supply device body 1, and the crushing scraper 12 is movably connected to the filter plate 10.

[0031] The main stirring rod 16 drives the auxiliary stirring rod 17 and the crushing scraper 12 to rotate synchronously during the rotation process, so that when the nutrient solution on the filter plate 10 is filtered through the filter holes 11, larger particles in the nutrient solution will be isolated by the filter plate 10 and then crushed by the rotating crushing scraper 12 to prevent the larger particles from causing subsequent blockage.

[0032] Reference Figure 2 The stirring mechanism includes a battery box 13 and a micro motor 14. The micro motor 14 is arranged inside the battery box 13, and a battery 15 is arranged above the micro motor 14. A main stirring rod 16 is fixedly arranged at the output end of the micro motor 14, and an auxiliary stirring rod 17 is fixedly arranged on the outer side of the main stirring rod 16. A scraper rod 18 is fixedly arranged on one side of the auxiliary stirring rod 17, and an electric heating wire 19 is fixedly arranged on one side of the main stirring rod 16 and the auxiliary stirring rod 17.

[0033] The main stirring rod 16 and the auxiliary stirring rod 17 are driven to rotate by the micro motor 14, and the auxiliary stirring rod 17 fully stirs the nutrient solution inside the supply device body 1. During the stirring process, the scraper rod 18 scrapes off the sediment adhering to the inner wall of the supply device body 1, and the main stirring rod 16 and the auxiliary stirring rod 17 evenly transfer the temperature of the electric heating wire to the nutrient solution during the stirring process, so as to avoid discomfort to critically ill patients during input.

[0034] Reference Figure 2 The main stirring rod 16 passes through the filter plate 10 and is fixedly connected to the fixed block 2. One end of the crushing scraper 12 is fixedly connected to the main stirring rod 16. The scraper rod 18 is movably connected to the inner wall of the supply device body 1. Support rods are fixedly provided at both ends of the battery box 13, and the support rods are fixedly connected to the inner wall of the supply device body 1.

[0035] The battery box 13 is fixed to the middle part of the supply device body 1 through the support rod, so that the main stirring rod 16 can drive the auxiliary stirring rod 17 to rotate evenly.

[0036] Reference Figure 1-2 A guide plate is symmetrically arranged inside the supply device body 1, a temperature sensor 20 is fixedly arranged on the top of the guide plate, and a plug 24 is sleeved on the top of the supply device body 1.

[0037] The temperature of the nutrient solution is constantly detected by the temperature sensor 20. Once the temperature of the nutrient solution is lower than the set value of the temperature sensor 20, a signal is transmitted to the control panel 22, so that the control panel 22 turns on the electric heating wire 19 to heat the nutrient solution.

[0038] Reference Figure 1 A control panel 22 is provided on the surface of the supply device body 1, a liquid level line 21 is provided on one side of the control panel 22, and a hanging rope 23 is fixedly provided on the top of the supply device.

[0039] The supply device body 1 can be hung by the hanging rope 23 , and the capacity of the nutrient solution can be observed through the liquid level line 21 on the surface of the supply device body 1 .

[0040] Working principle: When the staff needs to add nutrient solution into the supply device body 1, first separate the plug 24 from the top thread of the supply device body 1, and then directly inject the nutrient solution into the supply device body 1, and at the same time turn on the micro motor 14 through the control panel 22, so that the micro motor 14 drives the main stirring rod 16 to rotate. During the rotation of the main stirring rod 16, the auxiliary stirring rod 17 and the crushing scraper 12 will be driven to rotate synchronously. When the nutrient solution is injected, it will directly fall onto the filter plate 10 and be filtered through the filter hole 11, and the larger particles in the nutrient solution will be isolated by the filter plate 10. Then, the rotating crushing scraper 12 crushes the nutrient solution to prevent the larger particles from causing subsequent blockage. The crushed nutrient solution particles will pass through the filter hole 11 and fall onto the rotating auxiliary stirring rod 17 again. The auxiliary stirring rod 17 fully stirs the nutrient solution inside the supply device body 1. During the stirring process, the scraper 18 scrapes off the sediment adhering to the inner wall of the supply device body 1, which is not only convenient for subsequent cleaning, but also enables the use of the nutrient solution to be more sufficient. Finally, the volume of the nutrient solution is observed through the liquid level line 21 on the surface of the supply device body 1. The injection of the nutrient solution can be stopped when it reaches a certain standard. After the preparation work is completed, the hanging rope 23 is hung on the infusion stand, and then the docking plug 8 is threadedly separated from the docking head 7, and the external matching infusion tube is threadedly docked with the docking head 7, and the nutrient solution inside the supply device body 1 will enter the infusion tube through the filter screen 5 to provide nutrition to the critically ill patient. When the nutrient solution passes through the filter screen 5, the particles larger than the filter hole will be isolated for the second time. Driven by the main stirring rod 16, the scraper 3 and the scraper strip 4 will scrape and clean the particles, and clean the nutrient solution particles in the aperture of the filter screen 5, avoiding double clogging of the infusion tube and the filter screen 5, and effectively improving the patient's Use physical sensation; since the nutrient solution input process is slow, once the temperature of the nutrient solution is lower than the set value of the temperature sensor 20, a signal will be transmitted to the control panel 22, so that the control panel 22 turns on the electric heating wire 19, and the main stirring rod 16 and the auxiliary stirring rod 17 evenly transfer the temperature of the electric heating wire to the nutrient solution during the stirring process, thereby avoiding discomfort caused to critically ill patients during input; when cleaning, directly rotate the plug 24 and the docking head 7 to disassemble the threaded plug 6 and the plug 24 from the supply device body 1, so that the supply device body 1 can achieve the beneficial effect of easy cleaning, thereby reducing the difficulty of work for medical staff.
