Description

Technical Field

[0001] This invention relates to the field of hemodialysis technology, specifically to an auxiliary movement device for dialysis treatment. Background Technology

[0002] Dialysis is a vital treatment for end-stage renal disease patients to maintain their lives. Each dialysis session typically lasts 4-5 hours and is performed about 3 times a week. During long-term dialysis, patients must maintain a fixed position in bed or sit, which severely restricts limb movement and can easily lead to complications such as poor blood circulation, muscle atrophy, joint stiffness, and deep vein thrombosis. This not only reduces the patient's quality of life but may also affect the effectiveness of dialysis treatment and prognosis. Therefore, providing safe and convenient limb-assisted exercise during dialysis treatment is a key requirement for improving the patient's physical condition and reducing the risk of complications. Furthermore, appropriate exercise during dialysis treatment can improve the clearance rate of toxins from the patient's body.

[0003] However, existing dialysis auxiliary exercise devices have poor adaptability during use. The movement mechanism and support structure of existing devices are mostly fixed designs, which cannot be flexibly adjusted according to patients with different heights and limb lengths. This results in some patients not being able to use them comfortably. Moreover, different people have different exercise ability requirements, while existing dialysis auxiliary exercise devices have fixed exercise requirements, which is difficult to meet the needs of different people. Based on this, the present invention designs an auxiliary exercise device for dialysis treatment to solve the above problems. Summary of the Invention

[0004] This invention provides an auxiliary movement device for dialysis treatment, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary movement device for dialysis treatment, comprising a fixed frame, an adjusting threaded cylinder rotatably connected to one end of the bottom of the fixed frame, an adjusting screw threadedly connected inside the adjusting threaded cylinder, a movable plate fixedly connected to one end of the adjusting screw, a return spring welded to one end of the movable plate, a movable block welded to one end of the return spring, a limit block fixedly connected to the top of the movable block, an adjusting plate slidably connected to the top of the limit block, the adjusting plate and the limit block being connected by a fixing bolt, and a push plate mounted on one end of the adjusting plate by a screw.

[0006] A preferred auxiliary movement device for dialysis treatment includes a backrest fixedly connected to one end of the top of the fixed frame, a movable rod slidably connected inside the backrest, a pillow board installed on the top of the movable rod by screws, a pillow attached to one end of the pillow board, and a compression screw threadedly connected inside one end of the backrest.

[0007] An auxiliary movement device for dialysis treatment, preferably, has a moving groove provided at the position of the fixed frame corresponding to the moving rod, and the end face of the extrusion screw is in contact with the end face of the moving rod.

[0008] An auxiliary movement device for dialysis treatment, preferably, has a T-shaped groove at the position of the adjustment plate corresponding to the position of the limiting block, and the limiting block is slidably embedded in the T-shaped groove.

[0009] An auxiliary movement device for dialysis treatment, preferably, has positioning holes evenly distributed on the top surface of the adjustment plate, a positioning groove distributed on the top surface of the limiting block, and the fixing bolt passing through the positioning holes and positioned inside the positioning groove.

[0010] An auxiliary movement device for dialysis treatment, preferably, has a corresponding hole at the position of the fixed frame corresponding to the moving block, and the outer diameter of the moving block is equal to the inner diameter of the corresponding hole.

[0011] An auxiliary movement device for dialysis treatment, preferably, has a limiting post slidably connected to the top of the moving plate, and the limiting post is fixedly installed at the bottom of the fixing frame.

[0012] An auxiliary movement device for dialysis treatment, preferably wherein the moving block is slidably connected to the outside of the limiting post, the return spring is located outside the limiting post, and the outside of the limiting post is in contact with the inner wall of the return spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by adjusting the cooperation between the threaded cylinder and the adjusting screw, the initial position of the moving plate and the push plate can be flexibly adjusted; the sliding cooperation between the adjusting plate and the limiting block and the positioning function of the fixing bolt can accurately adjust the extension length of the push plate; the sliding cooperation between the moving rod and the backrest and the fixing function of the squeezing screw can flexibly adjust the height of the pillow board and the backrest; the multi-dimensional adjustment structure works synergistically to adapt to patients of different heights and limb lengths, greatly improving the comfort and versatility of use.

[0014] This can be achieved by adjusting the initial deformation of the reset spring. By rotating the adjusting screw cylinder, the moving plate slides along the limiting post, moving closer to or further away from the moving block, thereby adjusting the initial tension or compression state of the reset spring, changing the elastic force of the reset spring, and adapting to the different movement needs of patients.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: Figure 1-4 As shown, the present invention provides a technical solution: an auxiliary movement device for dialysis treatment, comprising a fixed frame 1, an adjusting threaded cylinder 2 rotatably connected to one end of the bottom of the fixed frame 1, an adjusting screw 3 threadedly connected inside the adjusting threaded cylinder 2, a movable plate 4 fixedly connected to one end of the adjusting screw 3, a limiting post 5 slidably connected to the top of the movable plate 4, the limiting post 5 being fixedly installed at the bottom of the fixed frame 1, a return spring 6 welded to one end of the movable plate 4, a movable block 7 welded to one end of the return spring 6, a limiting block 8 fixedly connected to the top of the movable block 7, an adjusting plate 9 slidably connected to the top of the limiting block 8, the adjusting plate 9 and the limiting block 8 being connected by a fixing bolt 10, and a push plate 11 installed at one end of the adjusting plate 9 by a screw; A backrest plate 12 is fixedly connected to one end of the top of the fixed frame 1. A moving rod 13 is slidably connected inside the backrest plate 12. A pillow plate 14 is installed on the top of the moving rod 13 by screws. A pillow 15 is glued to one end of the pillow plate 14. A compression screw 16 is threadedly connected to one end of the backrest plate 12.

[0019] The fixed frame 1 has a moving groove at the position corresponding to the moving rod 13. The end face of the extrusion screw 16 is in contact with the end face of the moving rod 13, which makes it easy to fix the moving rod 13 and thus make it easy to move the pillow board 14 to different heights, suitable for people of different heights.

[0020] A T-shaped groove is provided at the position of the adjusting plate 9 corresponding to the position of the limiting block 8. The limiting block 8 is embedded and slidably connected inside the T-shaped groove to prevent the adjusting plate 9 from falling off.

[0021] The top surface of the adjusting plate 9 is evenly provided with positioning holes, the top surface of the limiting block 8 is provided with positioning grooves, and the fixing bolt 10 passes through the positioning holes and is located inside the positioning groove, which makes it easy to fix the adjusting plate 9, and thus makes it easy to move the push plate 11 to a suitable position.

[0022] The fixed frame 1 has a corresponding hole at the position of the moving block 7. The outer diameter of the moving block 7 is equal to the inner diameter of the corresponding hole, which ensures the stability of the movement of the moving block 7 and allows for the limitation of the moving block 7, thereby facilitating the adjustment of the spring force of the return spring 6.

[0023] The movable block 7 is slidably connected to the outside of the limiting post 5, and the return spring 6 is located outside the limiting post 5. The outside of the limiting post 5 is in contact with the inner wall of the return spring 6, which ensures the stability of the movement of the movable block 7 and the stability of the tension and bending of the return spring 6.

[0024] Before use, adjust the device according to the patient's height and limb length. Rotate the squeezing screw 16 inside one end of the backrest 12 to separate the end face of the squeezing screw 16 from the end face of the moving rod 13, push the moving rod 13 to slide along the inside of the backrest 12, and move the top pillow board 14 and the pillow 15 to a suitable height. Then rotate the squeezing screw 16 in the opposite direction to make the end face of the squeezing screw 16 in close contact with the end face of the moving rod 13, and fix the moving rod 13 in the corresponding moving groove of the fixing frame 1 to complete the adjustment of the head support height.

[0025] Rotate the adjusting screw cylinder 2, and through the threaded transmission with the adjusting screw 3, drive the moving plate 4 to slide along the limiting post 5. Adjust the initial position of the moving plate 4, pull out the fixing bolt 10, push the adjusting plate 9 to slide along the limiting block 8, adjust the push plate 11 to a position that matches the length of the patient's limb, and then insert the fixing bolt 10 through the positioning hole of the adjusting plate 9 and into the positioning groove of the limiting block 8 to complete the fixation of the position of the push plate 11.

[0026] The patient sits on the device with their head resting on the pillow 15 and their limbs placed on one side of the push plate 11, ensuring that the limbs are in close contact with the push plate 11. At this time, the moving block 7 is in the corresponding hole of the fixing frame 1, and the outer diameter of the moving block 7 is equal to the inner diameter of the corresponding hole, ensuring that the moving block 7 can move stably; the reset spring 6 is in a naturally extended state, preparing for subsequent movement cushioning.

[0027] During dialysis treatment, the patient can push the push plate 11 independently, causing the adjustment plate 9, the limiting block 8, and the moving block 7 to move synchronously. The moving block 7 slides smoothly along the corresponding hole of the fixed frame 1, limiting the movement of the moving block 7. When the moving block 7 moves, it squeezes the return spring 6, which undergoes elastic deformation to generate a reverse elastic force, providing a buffer for limb movement. When the patient releases the push plate 11, the return spring 6 elastically returns to its original position, causing the moving block 7, the limiting block 8, the adjustment plate 9, and the push plate 11 to return to their original positions, realizing reciprocating auxiliary movement of the limb. During this process, the limiting post 5 precisely limits the sliding direction of the moving plate 4 to prevent the moving plate 4 from deviating. The cooperation between the limiting block 8 and the T-slot of the adjustment plate 9 prevents the adjustment plate 9 from falling, ensuring the stability and safety of the movement process.

[0028] If the intensity of exercise needs to be adjusted, it can be achieved by adjusting the initial deformation of the reset spring 6. Rotating the adjusting threaded cylinder 2 causes the moving plate 4 to slide along the limiting post 5, moving closer to or further away from the moving block 7, thereby adjusting the initial tension or compression state of the reset spring 6, changing the elastic force of the reset spring 6, and adapting to the different exercise capacity needs of the patient.

[0029] After dialysis treatment, the patient's limbs are removed from the push plate 11, the reset spring 6 drives all moving parts to reset, the fixing bolt 10 is pulled out, the adjusting plate 9 is pushed back to the initial position, the fixing bolt 10 is inserted to fix it, the adjusting threaded cylinder 2 is rotated to drive the moving plate 4 to reset; the squeezing screw 16 is rotated to adjust the moving rod 13 and the pillow plate 14 to the initial height and fix them, completing the device reset, which is convenient for subsequent storage and next use.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
