DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-8 A regulated blood transfusion auxiliary device for hematology includes a lifting plate 1 and a base 2. A protective frame 24 is fixedly installed on the top of the lifting plate 1. A bottom plate 25 is arranged on the top of the lifting plate 1. A connecting frame 3 is fixedly installed on the top of the bottom plate 25. Notches are provided on both sides of the top of the connecting frame 3. The inner walls of the two notches are rotatably connected with screw rods 4. The screw rods 4 penetrate through the moving block 5 and are threadedly connected with the moving block 5. The moving block 5 is slidably connected with the notch. The moving block 5 is rotatably connected with a rotating plate 6.

[0028] Among them, the four corners of the top of the rotating plate 6 are fixedly connected with a telescopic rod 11, the top of the telescopic rod 11 is fixedly connected with a heating clamp 12, and the four corners of the bottom of the heating clamp 12 are fixedly connected with a connecting spring 13, one end of the connecting spring 13 is fixedly connected to the top of the rotating plate 6, and the telescopic rod 11 runs through the inside of the connecting spring 13. The protective frame 24 provides effective protection for the blood bag and other key components during the blood transfusion process, avoids blood transfusion accidents caused by external factors such as collision, pollution, etc., and improves the safety and reliability of the blood transfusion process. At the same time, the rotating plate 6 can be flexibly rotated as needed, so that the blood bag can be easily erected or tilted, which is convenient for medical staff to observe the blood condition in the blood bag, and also provides convenience for blood mixing and heating during the blood transfusion process.

[0029] Among them; the top of the base 2 is fixedly installed with a connecting sleeve shaft 16, the inner wall of the connecting sleeve shaft 16 is slidably connected with a lifting rack 17, and one end of the lifting rack 17 is fixedly connected to the bottom of the lifting plate 1, and the connecting sleeve shaft 16 is fixedly installed with a connecting plate 18, one end of the connecting plate 18 is rotatably connected with a rotating rod 19, one end of the rotating rod 19 is coaxially fixedly connected with a spur gear 20, and the spur gear 20 is meshed with the lifting rack 17. The telescopic rod 11 not only provides stable support for the heating splint 12, but also allows it to be adjusted up and down within a certain range. This adjustment capability allows the heating splint 12 to fit blood bags of different sizes and shapes more tightly and evenly, thereby improving heating efficiency and heating uniformity.

[0030] Among them; the bottom plate 25 is fixedly installed with a rotating motor 7, one end of the output shaft of the rotating motor 7 is coaxially fixedly connected with a pulley 8, the inner wall of the pulley 8 is provided with two transmission belts 9, one end of the two transmission belts 9 is provided with a pulley 2 10, the pulley 2 10 is coaxially fixedly connected with one end of the screw rod 4, the screw rod 4 and the pulley 2 10 rotate synchronously, thereby realizing precise control of the moving block 5 and the rotating plate 6, as the screw rod 4 rotates, the moving block 5 will move linearly along its threaded trajectory, thereby driving the rotating plate 6 to adjust the angle.

[0031] Among them; a fixed block 15 is fixedly installed on the top of one end of the lifting plate 1, and both ends of the fixed block 15 are rotatably connected with auxiliary arm rods 14, one end of the two auxiliary arm rods 14 are rotatably connected to the side of the rotating plate 6, and one end of the two auxiliary arm rods 14 are fixedly connected with an extrusion block 26. The auxiliary arm rod 14 not only connects the lifting plate 1 and the rotating plate 6, but also provides additional support and stability for the rotating plate 6 through its swinging motion. When the rotating plate 6 rotates under the drive of the screw 4, the auxiliary arm rod 14 can swing accordingly with its rotation, thereby maintaining the balance and stability of the rotating plate 6.

[0032] The other end of the connecting plate 18 is rotatably connected to a cam 21 , and the cam 21 is fixedly connected to a connecting rod 22 .

[0033] wherein the four corners of the top of the base 2 are fixedly mounted with two telescopic rods 23, one end of the two telescopic rods 23 is fixedly connected to the four corners of the bottom of the lifting plate 1.

[0034] The connecting plate 18 is in an inverted triangle shape as a whole, there are two connecting plates 18, and the two connecting plates 18 are distributed on both sides of the connecting sleeve shaft 16.

[0035] Working principle: when in use, first, place the low-temperature stored blood bag on the top of the rotating plate 6 and firmly clamp it by the heating clamp 12. Then, start the rotating motor 7. The rotation of its output shaft will drive the pulley 1 8 connected to it to rotate together. Under the transmission action of the transmission belt 9, the rotation of the pulley 1 8 will further drive the pulley 2 10 and the screw 4 coaxially installed with the pulley 2 10 to rotate. This rotational movement then controls the movement of the moving block 5 threadedly connected to the screw 4. As the moving block 5 moves, one end of the rotating plate 6 will be gradually lifted, causing the originally flat blood bag to be erected. In this process, the rotating plate The ends of the auxiliary arms 14 connected by rotation on both sides of 6 will also be lifted up accordingly. The ends of these auxiliary arms 14 are connected to the squeezing blocks 26. As the lifting angle of the rotating plate 6 increases, the squeezing blocks 26 will generate increasingly greater squeezing forces on the heating clamping plates 12 due to the rotation. This gradually increasing squeezing force will lift up the heating clamping plates 12, thereby reducing its clamping force on the upright blood bag. This design not only helps to fully mix the blood inside the blood bag and improve the heating efficiency of the blood, but also effectively prevents the blood bag from falling off the rotating plate 6 through the appropriate clamping of the heating clamping plates 12. The whole process is both efficient and safe.

[0036] Finally, when adjusting the height of the device, by manually rotating the rotating rod 19, this action will drive the spur gear 20 coaxially fixedly installed at one end of the rotating rod 19 to rotate accordingly, and the spur gear 20 will mesh with the lifting rack 17, thereby driving the lifting rack 17 to move up and down along the inner wall trajectory of the connecting sleeve shaft 16. This movement in turn controls the height adjustment of the lifting plate 1 connected to the top of the lifting rack 17 and all the components installed above it. When the lifting plate 1 and the components on its top are adjusted to the required height position, the user will then rotate the connecting rod 22 downward. This operation causes the cam 21 at the end of the connecting rod 22 to start rotating until the protruding part of the cam 21 contacts the lifting rack 17 and generates pressure, thereby firmly limiting the lifting rack 17 inside the connecting sleeve shaft 16. This limiting mechanism ensures that the lifting plate 1 and the components on its top can be maintained at the current height position, achieving accurate positioning and a stable state. The entire operation process is simple and efficient, meets the needs of height adjustment and positioning, and is suitable for operators of different heights.
