Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically a bed-based counting-assisted ankle pump exercise device. Background Technology

[0002] The bed-based counting-assisted ankle pump exercise device is a medical device specifically designed for lower limb rehabilitation. It aims to help patients promote blood circulation, enhance muscle strength and flexibility through active ankle joint movements.

[0003] Currently, traditional bed-based counting-assisted ankle pump exercise devices involve placing the patient's foot on the foot support part of the device. The ankle joint's plantar flexion movement (i.e., the toes pointing downwards) drives the spring to move. When the spring moves to the designated position, the counter will automatically jump once, recording one valid movement. The patient can repeat the ankle pump exercise as needed to achieve the predetermined number of movements and goals.

[0004] However, as the rehabilitation process progresses, the patient's ankle strength and flexibility will show a significant improvement trend. This means that as the patient's ability increases, the original spring pressure setting may soon become unsuitable. Most existing traditional ankle pump exercise devices use a fixed spring pressure design, which cannot be dynamically adjusted according to the patient's rehabilitation progress. When the patient's ankle strength reaches a certain level, if a low-pressure spring is continued to be used, it will no longer be able to provide enough load to stimulate further muscle growth and strength improvement, thereby reducing the rehabilitation effect. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a bed-based counting-assisted ankle pump exercise device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bed-based counting-assisted ankle pump exercise device, comprising a base plate, a placement plate rotatably connected to the top of the base plate, a motion spring being provided inside the top of the base plate, a square block being fixedly installed at one end of the motion spring, and the square block being able to slide inside the base plate, the placement plate and the square block being hinged together by a hinge rod, and a counter being provided on one side of the base plate;

[0007] An adjustment mechanism is located inside the base plate. The adjustment mechanism includes an L-shaped plate, which is located inside the base plate. A second motion spring is fixedly installed on one side of the L-shaped plate. A connecting plate is fixedly installed on one end of the second motion spring, and the connecting plate can slide inside the L-shaped plate. Fixing blocks are fixedly installed on both sides of the L-shaped plate. A square plate located at the bottom end of the L-shaped plate is slidably connected inside the base plate. Two extrusion blocks are fixedly installed at both ends of the top of the square plate. A threaded rod is rotatably connected to one side of the base plate. A threaded block is threadedly sleeved on the surface of the threaded rod, and one side of the threaded block is fixedly connected to one side of the extrusion block.

[0008] Preferably, a return spring is fixedly installed at the top of the bottom plate, and the bottom end of the return spring is fixedly connected to one side of the L-shaped plate.

[0009] Preferably, a limiting rod located inside the square plate is fixedly installed inside the base plate, and the square plate can slide on the surface of the limiting rod.

[0010] Preferably, two friction plates are fixedly installed at the bottom end of the base plate, and the friction plates are longitudinally symmetrical about the center of the base plate, with a circular groove opened at the bottom end of each of the two friction plates.

[0011] Preferably, the side opposite to the pressing block and the fixing block is designed with an inclined surface, and the two inclined surfaces are parallel to each other.

[0012] Preferably, there are two motion springs, which are laterally symmetrical about the center of the base plate. The hinge rod, the L-shaped plate and the second motion spring are all located on opposite sides of the two first motion springs, and there is a gap between the first motion springs.

[0013] Preferably, a gap is provided between the square plate and the L-shaped plate, and a square groove is provided inside the bottom plate, allowing the square plate to slide inside the square groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a rotating threaded rod, causing a threaded block to move on its surface. This movement drives a square plate and two compression blocks, which in turn compress a fixed block, causing it to move upwards. The fixed block then moves an L-shaped plate, a second motion spring, and a connecting plate upwards. The connecting plate moves to one side of the square block. When the patient's toes point downwards, the square block contacts the connecting plate. The patient requires more force to push the connecting plate, compressing the second motion spring. Simultaneous compression of both the first and second motion springs allows the patient to exercise at a high intensity. Finally, rotating the threaded rod moves the second motion spring and the connecting plate to one side of the square block, increasing the downward force of the toes and thus more effectively exercising the muscles and ligaments around the ankle joint, improving rehabilitation outcomes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a counting-assisted ankle pump exercise device for beds, including a base plate 1, a placement plate 2 rotatably connected to the top of the base plate 1, a motion spring 3 inside the top of the base plate 1, a square block 4 fixedly installed at one end of the motion spring 3, and the square block 4 can slide inside the base plate 1, the placement plate 2 and the square block 4 are hinged by a hinge rod 5, and a counter 17 is provided on one side of the base plate 1.

[0025] An adjustment mechanism is located inside the base plate 1. The adjustment mechanism includes an L-shaped plate 6, which is located inside the base plate 1. A second motion spring 7 is fixedly installed on one side of the L-shaped plate 6. A connecting plate 8 is fixedly installed on one end of the motion spring 7 and can slide inside the L-shaped plate 6. Fixing blocks 11 are fixedly installed on both sides of the L-shaped plate 6. A square plate 9 located at the bottom end of the L-shaped plate 6 is slidably connected inside the base plate 1. Two pressing blocks 10 are fixedly installed at both ends of the top of the square plate 9. A threaded rod 13 is rotatably connected to one side of the base plate 1. A threaded block 12 is threadedly sleeved on the surface of the threaded rod 13 and one side of the threaded block 12 is fixedly connected to one side of the pressing block 10.

[0026] Using the above method: The operator places the patient's foot on one side of the placement plate 2, and then uses straps to fix the leg and foot. After the fixation is completed, the patient can plantarflex the ankle joint, that is, hook the toes downward to drive the placement plate 2 to rotate. Since the placement plate 2 and the square block 4 are hinged by the hinge rod 5, when the placement plate 2 rotates, it will drive the hinge rod 5 to drive the square block 4 to slide inside the base plate 1. When the square block 4 moves, it will compress the motion spring 3. During the compression of the motion spring 3, the counter 17 will automatically jump once to record one valid movement.

[0027] When it is necessary to increase the ankle joint's movement strength, the threaded rod 13 can be rotated. Since the threaded rod 13 is threadedly connected to the threaded block 12, the threaded block 12 will move on the surface of the threaded rod 13 when the threaded rod 13 rotates. The threaded block 12 will drive the pressing block 10 to move. Since both pressing blocks 10 are fixed to the top of the square plate 9, the pressing block 10 will drive the square plate 9 and the other pressing block 10 to move. At this time, the two pressing blocks 10 will simultaneously contact one side of the fixed block 11 and will press the fixed block 11 upward. The fixed block 11 will then drive the L-shaped plate 6, the second motion spring 7, and the connecting... As plate 8 moves upward, connecting plate 8 moves to one side of square block 4. When the patient's toes point downward, square block 4 contacts connecting plate 8. The patient needs more force to push connecting plate 8 to move. As connecting plate 8 moves, it compresses motion spring 2 7. Then, motion spring 1 3 and motion spring 2 7 are compressed simultaneously, allowing the patient to exercise at a high intensity. Finally, by rotating threaded rod 13, motion spring 2 7 and connecting plate 8 move to one side of square block 4, increasing the force of the patient's toes pointing downward, thus more effectively exercising the muscles and ligaments around the ankle joint and improving the rehabilitation effect.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, a return spring 14 is fixedly installed at the top of the base plate 1. The bottom end of the return spring 14 is fixedly connected to one side of the L-shaped plate 6. A limiting rod 15 located inside the square plate 9 is fixedly installed inside the base plate 1, and the square plate 9 can slide on the surface of the limiting rod 15.

[0029] The above solution is adopted as follows: By designing the return spring 14, when the pressing block 10 pushes the L-shaped plate 6 upward, the return spring 14 will be compressed. During the compression process, the L-shaped plate 6 can be limited. When the pressing block 10 is away from the fixed block 11, the compressed return spring 14 will push the L-shaped plate 6, the motion spring 7 and the connecting plate 8 to reset. By designing the square plate 9 and the limiting rod 15, when the square plate 9 moves, it will move on the surface of the limiting rod 15. Thus, the limiting rod 15 can limit the moving square plate 9, thereby improving the stability of the square plate 9.

[0030] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, two friction plates 16 are fixedly installed at the bottom end of the base plate 1. The friction plates 16 are longitudinally symmetrical about the center of the base plate 1. The bottom ends of the two friction plates 16 are provided with circular grooves. The side opposite to the pressing block 10 and the fixing block 11 is designed with a slope, and the two slopes are parallel to each other.

[0031] The above solution is adopted as follows: Through the design of the friction plate 16, when the device is placed on the bed, the surface of the friction plate 16 will contact the bed surface. Since the bottom end of the friction plate 16 has a circular groove and is symmetrically designed, the friction between it and the bed can be increased, thereby improving the stability of the device. Through the design of the pressing block 10 and the fixing block 11, since the opposite side of the pressing block 10 and the fixing block 11 are both designed with slopes, the resistance will be reduced when one side of the pressing block 10 contacts the other side of the fixing block 11, thereby facilitating the pressing block 10 to push the fixing block 11 upward.

[0032] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, there are two motion springs 3, which are designed to be symmetrical about the center of the base plate 1. The hinge rod 5, the L-shaped plate 6 and the motion spring 7 are all located on the opposite side of the two motion springs 3, and there is a gap between the motion springs 3. There is a gap between the square plate 9 and the L-shaped plate 6. A square groove is opened inside the base plate 1, and the square plate 9 can slide inside the square groove.

[0033] The above scheme is adopted: through the design of hinge rod 5, L-shaped plate 6 and motion spring 7, since motion spring 3 is symmetrically designed, the square block 4 can move smoothly. Furthermore, hinge rod 5, L-shaped plate 6 and motion spring 7 are set on the opposite side of motion spring 3 and have a gap, so motion spring 3 will not interfere with it, and it is convenient for the square block 4 to push the connecting plate 8 to move smoothly. Through the design of square plate 9, there is a gap between L-shaped plate 6 and square plate 9, so square plate 9 will not interfere with the movement of L-shaped plate 6, and square plate 9 can move inside the square groove, so the bottom plate 1 will not interfere with the movement of square plate 9.

[0034] Working principle and usage process of this utility model:

[0035] First, the operator needs to place the patient's foot on one side of the placement plate 2 and put the leg inside the base plate 1. Then, use the straps to fix it. After the fixation is completed, the patient can hook their toes down and push the placement plate 2 to rotate. The placement plate 2 will drive the hinge rod 5 to move the square block 4. Then the motion spring 3 will be squeezed. During the compression of the motion spring 3, the counter 17 will automatically jump once to record one valid movement.

[0036] When it is necessary to increase the strength of ankle joint movement, the threaded rod 13 can be rotated, and the threaded block 12 will move on the surface of the threaded rod 13. The threaded block 12 will drive the square plate 9 and the two compression blocks 10 to move. The two compression blocks 10 will squeeze the fixed block 11 to move upward. The fixed block 11 will drive the L-shaped plate 6, the second motion spring 7 and the connecting plate 8 to move upward. The connecting plate 8 will move to one side of the square block 4. When the patient's toes are hooked downward, the square block 4 will contact the connecting plate 8. When the patient needs more force, he will push the connecting plate 8 to move, and the second motion spring 7 will be compressed. Then, through the simultaneous compression of the first motion spring 3 and the second motion spring 7, the patient can exercise under high intensity and finally complete the operation process.
