Technical Field
[0001] The present invention relates to the technical field of nutrition, and specifically to a nutrition department nutrient solution feeding device. Background Art
[0002] In the field of medical nutrition, nutrient solution feeding is an important means of nutritional supplementation for patients who are unable to eat independently. Most traditional nutrient solution feeding devices adopt a combination of a simple liquid storage container and a feeding tube. Although they can meet the basic feeding needs, there are many inconveniences in actual use.
[0003] Firstly, the position of the liquid storage container of the traditional feeding device is fixed and cannot be flexibly adjusted according to the position of the hospital bed, which brings great inconvenience to medical staff during the feeding operation. Secondly, the active ingredients in the nutrient solution are prone to precipitation during long-term static placement, resulting in poor use effects of the nutrient solution. However, the traditional feeding device lacks an automatic stirring function and cannot effectively solve this problem. In addition, when supplementing the nutrient solution, the lid of the liquid storage container needs to be manually opened in the traditional feeding device, which is cumbersome to operate and easily introduces bacterial contamination.
[0004] Therefore, in order to solve the above problems and improve the efficiency and effect of nutrient solution feeding, it is necessary to design a new nutrient solution feeding device to achieve functions such as adjustable position of the liquid storage container, automatic stirring, convenient supplement of the nutrient solution, and precise control of the feeding amount.

The slider 14 on the rear side of the liquid storage tank 1 is slidably connected to the chute 13 on the front side of the slide rail 12. The top end of the slide rail 12 is horizontally welded with a fixing plate 17. Through holes 18 are penetrated through both sides of the fixing plate 17; adjustment mechanism: used to adjust the use position of the liquid storage tank 1. The adjustment structure includes a servo motor 16 and a lead screw 15. The lead screw 15 horizontally penetrates through the middle of the slider 14 and is threadedly connected to the slider 14. The shaft end of the servo motor 16 is fixedly connected to one end of the lead screw 15. The servo motor 16 is fixedly connected to one side of the slide rail 12. The lead screw 15 is rotatably connected to the slide rail 12 through a bearing.
[0028] It should be noted that by passing bolts through the through holes 18 on both sides of the fixing plate 17, the slide rail 12 can be horizontally fixed at a specified position at the top of the ward according to the position of the hospital bed. By controlling the servo motor 16 to work through the corresponding controller, the lead screw 15 can be driven to rotate. Through the sliding connection between the chute 13 on the front side of the slide rail 12 and the slider 14 on the rear side of the liquid storage tank 1, during the rotation of the lead screw 15, the liquid storage tank 1 can be driven to move smoothly outside the slide rail 12, facilitating the rapid adjustment of the position of the liquid storage tank 1 according to the position of the hospital bed and facilitating the medical staff to perform the nutrient feeding operation.
[0029] Embodiment 2: Refer to Figures 1-5, Stirring mechanism: used to automatically stir the nutrient solution inside the liquid storage tank 1. The stirring mechanism includes a gear 22. A first driving rod 23 is vertically welded to the middle of the bottom side of the gear 22. The bottom end of the first driving rod 23 is rotationally connected to the upper surface of the liquid storage tank 1 through a bearing. Above the front side of the slide rail 12, an installation groove 2 is horizontally opened. A rack 21 is horizontally welded to the rear inner wall of the installation groove 2. The gear 22 meshes with the rack 21. The middle of the inner wall of the top end of the liquid storage tank 1 is rotationally connected to a second driving rod 25 through a bearing. A second pulley 26 is fixedly installed at the top end of the second driving rod 25. The lower end of the first driving rod 23 passes through the middle of the first pulley 24 and is fixedly connected to the first pulley 24. The first pulley 24 is drivingly connected to the second pulley 26 through a transmission belt 27. A stirring rod 28 is fixedly installed at one end of the second driving rod 25 inside the liquid storage tank 1.
[0030] It should be noted that through the engagement of the rack 21 inside the installation groove 2 on the front side of the slide rail 12 and the gear 22 at the top end of the liquid storage tank 1, when the servo motor 16 drives the liquid storage tank 1 to move, the rack 21 can drive the gear 22 to rotate, thereby driving the first pulley 24 at the lower end of the first driving rod 23 to rotate. Through the transmission belt 27, the second pulley 26 and the second driving rod 25 can be driven to rotate, thereby driving the stirring rod 28 at the lower end of the second driving rod 25 to rotate inside the liquid storage tank 1, and the nutrient solution inside the liquid storage tank 1 can be evenly stirred, avoiding the precipitation of active ingredients in the nutrient solution and affecting the use effect of the nutrient solution, with a high degree of automation.

The liquid outlet pipe 11 is communicated with the feeding pipe 42 through the connecting sleeve 4 and the connecting head 41. A second electromagnetic flow valve 43 is arranged inside the liquid outlet pipe 11.
[0034] It should be noted that by threadedly connecting the connecting head 41 at the top end of the feeding pipe 42 to the connecting sleeve 4 at the bottom end of the liquid outlet pipe 11, it is convenient for the installation and disassembly of the feeding pipe 42 and the liquid outlet pipe 11. Control the second electromagnetic flow valve 43 to open through the corresponding controller, and a quantitative nutrient solution inside the liquid storage tank 1 can be discharged through the feeding pipe 42 for feeding operations.
