Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of leg training, in particular to a leg training device for hemodialysis. Background Art
[0002] Dialysis is a separation and purification technology that separates small molecules from biomacromolecules by the principle of small molecules diffusing into water (or buffer) through a semipermeable membrane. Dialysis therapy is a treatment method that allows components (solutes or water) in body fluids to be excreted from the body through a semipermeable membrane. When patients undergo dialysis on a nursing bed, they are generally unable to move, so appropriate training of the patient's legs is required to increase blood flow, improve the clearance rate of solutes during dialysis, and reduce solute rebound after dialysis.
[0003] Existing dialysis leg training devices are broadly categorized as simple or complex. Simple devices, such as an elastic band, are easy to wear but offer limited training options. Complex devices, on the other hand, often require a nurse to assist in fitting the device on the patient's foot or leg. Patients needing to rest during training or exercise afterward can significantly increase the nurse's workload. Nurses often care for multiple patients simultaneously, leading to a heavy workload.
[0004] For example, the patent application CN215841399U shows a bed exercise device suitable for hemodialysis patients, which includes a first pad and a second pad provided at one end of the first pad. The patent requires the nurse to wrap the sandbag tightly around the calf. Another example is the common dialysis bicycle device on the market, which requires the nurse to adjust the straps on the pedals.
[0005] Therefore, we propose a leg training device for hemodialysis to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to solve the problem in the prior art that nurses need auxiliary wearing and have heavy workload, and to propose a leg training device for hemodialysis.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A leg training device for hemodialysis comprises a base plate, a mounting plate hingedly connected to one side of the top surface of the base plate, and an adjustment assembly for adjusting the rotation angle of the mounting plate provided on the other side, wherein the adjustment assembly is located below the mounting plate, and a training box is fixedly connected to the middle of the top surface of the mounting plate;
[0009] Both sides of the training box are vertically provided with a slide groove, and a slider is slidably provided in the slide groove, and an elastic component for driving the slider to move downward is also provided in the slide groove, and a rotating block is rotatably provided on the opposite sides of the two sliders, and a clamping block is hingedly provided in the middle of the opposite sides of the two rotating blocks, and an elastic band is detachably provided between the clamping block and the rotating block, and auxiliary plates are fixed on the upper and lower sides of the clamping block, and a notch for inserting the elastic band is provided on one side of the auxiliary plate;
[0010] The top surface of the training box is arc-shaped, and a handle is fixedly connected to one side of the top surface of the training box close to the adjustment component, and a massage component for massaging the soles of the feet or the calves is provided on the other side.
[0011] Preferably, the elastic component includes a telescopic rod fixedly connected between the top surface of the slider and the top of the slide groove, and a compression spring is sleeved on the outer side of the telescopic rod.
[0012] Preferably, the upper portion of the slide groove is fixedly connected to a limit plate, and the maximum stroke of the slider below the limit plate is smaller than the maximum stroke of the telescopic rod and the compression spring.
[0013] Preferably, the widths of the two auxiliary plates are both greater than the width of the clamping plate.
[0014] Preferably, the sides of the slider, clamping block and auxiliary plate are all rounded.
[0015] Preferably, the adjustment assembly includes an adjustment plate fixedly connected to the top surface of the mounting plate, and U-shaped adjustment rods rotatably connected to both sides of the mounting plate. The top surface of the adjustment plate is provided with a plurality of adjustment slots for inserting the adjustment rods.
[0016] Preferably, an auxiliary groove is provided on the lower portion of one side of the adjustment plate away from the hinge of the mounting plate.
[0017] In summary, the technical effects and advantages of this utility model are as follows: Compared with existing devices, this hemodialysis leg training device uses a clamp to fix the elastic band, and auxiliary plates bend the elastic bands on both sides. When the elastic band hangs naturally, the auxiliary plates leave space in the middle, making it easier for the patient to insert their feet. Compared with existing devices, this device avoids the problem of nurses assisting in donning the bands during training, reducing the nurses' workload.
[0018] In addition, the elastic band allows for outward leg force training, while the chute and slider combined with the elastic component enable single or double leg lifts. A rotating block allows for the elastic band to rotate, enabling kicking training. The massage component on the top of the training box provides sole or calf massage. Compared to existing devices, this device offers a wider range of training functions, meeting the diverse training needs and interests of dialysis patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Reference Figure 1-4 A leg training device for hemodialysis includes a base plate 1, a mounting plate 2 is hinged on one side of the top surface of the base plate 1, and an adjustment component for adjusting the rotation angle of the mounting plate 2 is provided on the other side, and the adjustment component is located below the mounting plate 2, and a training box 3 is fixedly connected to the middle of the top surface of the mounting plate 2.
[0028] Both sides of the training box 3 are vertically provided with a slide groove 4, and a slider 5 is slidably provided in the slide groove 4. The slide groove 4 is also provided with an elastic component that drives the slider 5 to move downward. The two sliders 5 are rotatably provided with a rotating block 6 on the opposite side of the two sliders 5. A clamping block 7 is hinged in the middle of the opposite side of the two rotating blocks 6. A detachable elastic belt 8 is provided between the clamping block 7 and the rotating block 6. Auxiliary plates 9 are fixed on the upper and lower sides of the clamping block 7, and a notch 10 for the elastic belt 8 to be placed in is provided on one side of the auxiliary plate 9.
[0029] The top surface of the training box 3 is arc-shaped, and a handle 11 is fixedly connected to one side of the top surface of the training box 3 close to the adjustment component, and a massage component 12 for massaging the soles of the feet or calves is provided on the other side.
[0030] Before using the leg training device for hemodialysis, the nurse places the device at the end of the bed and faces one side of the massage component 12 toward the patient. The nurse then adjusts the rotation angle of the mounting plate 2 by adjusting the component until the position of the elastic band 8 is suitable for the patient's strength training.
[0031] After this is complete, the patient can begin training. The auxiliary plate 9 and the clamping block 7 work together to create a gap in the middle of the elastic band 8. The patient can pass through this gap and insert their feet into the elastic band 8 until the elastic band 8 is at the calf, completing the wearing of the device.
[0032] The first training item is to push the legs outwards, and at this time the elastic band 8 is deformed to provide training force for the legs.
[0033] The second training item is to lift the legs with one or both legs. At this time, the slider 5 is subjected to an upward force and drives the compression spring 14 to compress. The compression of the compression spring 14 and the deformation of the elastic band 8 provide training force for the legs; the compression stroke of the compression spring 14 and the deformation of the elastic band 8 provide a training stroke for leg lifting.
[0034] The third exercise is the leg kick. Before starting, the patient needs to retract their feet to the elastic band 8 and press the band 8 with the arch of their foot. The rotating block 6 rotates until the side of the elastic band 8 is in contact with the arch of the foot. This allows the leg kick to begin. The elastic band 8 deforms during the kick, providing training force for the legs.
[0035] In practice, the three training programs described above can be combined, such as the first and second training programs. The second training program provides a normal downward pressure on the legs, similar to a sandbag. Then, perform the first training program to simulate weight-bearing and push the legs outward. Other combinations are not detailed here.
[0036] The massage assembly 12 is currently available. Commonly available massage assemblies 12 include vibration, airbag, and microcurrent types. The airbag type will be used for further explanation. The massage assembly 12 includes an airbag mounted on the top surface of the training box 3, baffles fixedly mounted on either side of the airbag, and an air pump mounted within the training box 3 to inflate the airbag.
[0037] After training, the patient retracts his foot from the elastic band 8 and can perform the massage step. During massage, the foot or calf is placed in the air bag of the massage assembly 12, the air pump is turned on and the air bag is inflated, and the air bag massages the patient thus.
[0038] The elastic band 8 should be made of durable rubber elastic band 8. The installation method of the clamp block 7 is the existing technology, including a card block, a card slot and a button. One side of the clamp block 7 is hinged on the rotating block 6, and the other side is fixed and unlocked on the rotating block 6 by the card block cooperating with the card slot. When the elastic band 8 needs to be replaced, press the button to drive the card block out of the card slot to unlock one side of the clamp block 7. Remove the old elastic band 8 and place the new elastic band 8 in the gap 10 of the two auxiliary plates 9. At this time, rotate the clamp block 7 and clamp the elastic band 8 to fix it. The clamp block 7 is fixed by the card block cooperating with the card slot. The disassembly and replacement of the elastic band 8 is completed.
[0039] The elastic assembly includes a telescopic rod 13 fixedly connected between the top surface of the slider 5 and the top of the chute 4. A compression spring 14 is sheathed around the outer side of the telescopic rod 13. The compression spring 14 remains compressed during use, providing downward force for the slider 5. Because the compression spring 14 must deform to a length sufficient to cover the required leg-lifting range, it requires a longer length. A longer compression spring 14 may shift in the middle during deformation, and the telescopic rod 13 limits the position of the compression spring 14, improving the stability of the device.
[0040] A limit plate 15 is fixedly connected to the upper portion of the chute 4, and the maximum travel of the slider 5 below the limit plate 15 is less than the maximum travel of the telescopic rod 13 and the compression spring 14. Since the compression spring 14 cannot be infinitely compressed, the limit plate 15 limits the slider 5 to prevent the slider 5 from moving a distance greater than the maximum deformation of the compression spring 14, which could damage the compression spring 14, thereby improving the stability of the device.
[0041] The width of the two auxiliary plates 9 is greater than the width of the splint, so that the elastic band 8 is C-shaped at the splint, making it easier for the patient to put his foot in and wear it.
[0042] The sides of the slider 5, the clamping block 7 and the auxiliary plate 9 are all rounded to avoid sharp edges from causing harm to the patient and improve the safety of the device.
[0043] Reference Figure 5-6 The adjustment assembly includes an adjustment plate 16 fixedly connected to the top surface of the mounting plate 2, and U-shaped adjustment rods 17 rotatably connected to both sides of the mounting plate 2. The top surface of the adjustment plate 16 is provided with multiple adjustment slots 18 for the adjustment rods 17 to insert into. After rotating the mounting plate 2 and the training box 3 by lifting the handle, the adjustment rods 17 are rotated until one side of the adjustment rod 17 is inserted into the adjustment slot 18, achieving angle adjustment.
[0044] An auxiliary groove 19 is provided on the lower part of the side of the adjustment plate 16 away from the hinge of the mounting plate 2. Through the auxiliary groove 19, when the personnel move the device by the handle, the adjustment rod 17 automatically blocks the auxiliary groove 19, thereby limiting the bottom plate 1 and preventing the bottom plate 1 from rotating and affecting the transportation.
[0045] Counterweights can be fixed on both sides of the mounting plate 2 to prevent the training box 3 from tipping over due to its center of gravity being too high. It can also minimize the problem of the patient lifting the mounting plate 2 when doing leg-lifting exercises, thereby improving the stability and safety of the device operation.
[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
