Description

Technical Field

[0001] This invention relates to the field of rehabilitation training technology, specifically to an ankle joint mobility rehabilitation training device. Background Technology

[0002] In the burn unit, patients with ankle and foot burns often develop ankle and foot joint contractures. Therefore, patients with ankle and foot burns need to undergo rehabilitative traction exercises during treatment to effectively prevent ankle and foot joint contractures and their complications, thus facilitating their recovery and cure.

[0003] In real-world clinical treatment, most burn patients, during their recovery phase, are often only able to move their ankles in a relatively passive manner. Specifically, due to the pain and weakness caused by burns, even when they have some voluntary mobility, they often choose to move little or not at all for various reasons. This situation directly leads to severely insufficient ankle joint mobility, which is detrimental to the recovery of their function.

[0004] In addition, another issue that cannot be ignored is that many patients experience anxiety and fear when faced with external assistance in ankle joint movements, due to the inconsistent application of force—sometimes gentle, sometimes too strong. This psychological resistance makes it even more difficult for them to accept passive ankle joint movements.

[0005] For medical staff or patients' families, while they are doing their best to help patients with ankle joint movements, this work is not only arduous and time-consuming, but also prone to delays due to the busyness or negligence of the medical staff or family members. This can result in insufficient time for ankle joint movement or difficulty in maintaining the frequency and regularity of the movements. This situation undoubtedly has a negative impact on the patient's recovery process.

[0006] Therefore, we proposed an ankle joint mobility rehabilitation training device to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an ankle joint mobility rehabilitation training device, which solves the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution: An ankle joint mobility rehabilitation training device includes an adjustable load-bearing structure, a limb placement structure at the end of the adjustable load-bearing structure, and an adjustable counterweight structure at the end of the limb placement structure. The limb placement structure includes a mounting frame, the bottom end of which is connected to the ground or other platform via a ground contact seat. A first hinge frame is hinged to the inner side of the mounting frame, and a second hinge frame is rotatably connected to the tail end of the first hinge frame. A foot contact plate is rotatably connected to the side of the second hinge frame away from the first hinge frame. A follower frame is fixedly connected to the bottom end of the second hinge frame, and a hinge block is rotatably connected to the bottom end of the follower frame.

[0009] Furthermore, the adjustable load-bearing structure includes a mounting plate, inside which a movable plate is provided, and the top of the mounting plate is movably connected to a positioning pin through five positioning holes, and the mounting plate and the movable plate are movably engaged by the positioning pins.

[0010] Furthermore, the movable plate is provided with a movable rod inside, and the top of the movable plate is movably connected to a fixing pin through five fixing holes. The movable plate and the movable rod are movably engaged by the fixing pin.

[0011] Furthermore, a seat structure is fixed to the top of the movable rod, and the seat cushion and backrest of the seat structure are both soft rubber pads, and a side handle is provided on the side end of the seat structure.

[0012] Furthermore, both the first and second hinge frames are provided with leg fixing devices on their inner sides. The leg fixing devices include fixing guards, with a fitting strap at the bottom end of the fixing guards and a fixing strap at the top end of the fixing guards.

[0013] Furthermore, the inner side of the fixing protective gear is provided with a fitting pad, which is a cushioning silicone pad, and both the fitting strap and the fixing strap are composed of a Velcro main strap and a Velcro sub strap.

[0014] Furthermore, the adjustable counterweight structure includes a gantry frame, a base plate is fixedly installed at the bottom end of the gantry frame, a slide rail is fixedly installed on the front side of the base plate, a slider is slidably connected to the top end of the slide rail, and the top end of the slider is fixedly connected to the bottom end of the hinge block.

[0015] Furthermore, a first transmission wheel is rotatably connected to the front side of the slide rail, a second transmission wheel is rotatably connected to the top of the base plate, a sliding vertical rod is fixedly connected to the inner side of the gantry frame, and a follower counterweight and a movable counterweight are slidably connected to the surface of the sliding vertical rod.

[0016] Furthermore, a connecting rod is fixedly installed on the inner side of the follower counterweight, and a lifting rope is wound around the top of the connecting rod. The other end of the lifting rope is connected to the front end of the slider in sequence through the second transmission wheel and the first transmission wheel.

[0017] Furthermore, a lifting block is fixedly sleeved on the surface of the sliding vertical rod, the bottom end of the movable counterweight overlaps with the top end of the lifting block, the interior of the movable counterweight has an insertion interface adapted to the insertion rod, and the movable counterweight and the insertion rod are movably engaged by an insertion pin.

[0018] Compared with the prior art, the present invention provides an ankle joint mobility rehabilitation training device, which has the following beneficial effects: This invention utilizes a limb placement structure and an adjustable weight structure. The limb placement structure effectively immobilizes the patient's lower limbs, ensuring stability while allowing for flexible flexion and extension movements of the knee and ankle joints, thereby promoting blood circulation and joint function recovery.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] like Figure 1-8 As shown, an ankle joint mobility rehabilitation training device proposed in one embodiment of the present invention includes an adjustable bearing structure 1, a limb placement structure 2 at the end of the adjustable bearing structure 1, and an adjustable counterweight structure 3 at the end of the limb placement structure 2.

[0023] The limb placement structure 2 includes a mounting frame 201. The bottom end of the mounting frame 201 is connected to the ground or other platform via a ground contact seat 202. A first hinge frame 203 is hinged to the inner side of the mounting frame 201. A second hinge frame 204 is rotatably connected to the tail end of the first hinge frame 203. A foot contact plate 205 is rotatably connected to the side of the second hinge frame 204 away from the first hinge frame 203. A follower frame 206 is fixedly connected to the bottom end of the second hinge frame 204. A hinge block 207 is rotatably connected to the bottom end of the follower frame 206.

[0024] By utilizing the hinge design of the first hinge frame 203 and the second hinge frame 204, the entire limb placement structure 2 can simulate the natural flexion and extension movements of the human ankle joint.

[0025] During use, the patient fixes their lower limbs in the leg fixation device 208. By adjusting the relative angle between the first hinge frame 203 and the second hinge frame 204, the ankle joint can be effectively trained for flexion and extension.

[0026] Meanwhile, the rotating connection design of the follower frame 206 and the hinge block 207 further enhances the flexibility and stability of training, ensuring the safety and comfort of patients during the training process.

[0027] In addition, the design of the foot-fitting plate 205 can closely fit the patient's foot, providing sufficient support and making the training effect more significant.

[0028] like Figure 2 As shown, in some embodiments, the adjustable bearing structure 1 includes a mounting plate 101, a movable plate 102 is provided inside the mounting plate 101, and a positioning pin 103 is movably inserted into the top of the mounting plate 101 through five positioning holes. The mounting plate 101 and the movable plate 102 are movably engaged by the positioning pin 103.

[0029] Specifically, the movable plate 102 can slide inside the mounting plate 101 to adjust the position of the seat structure 106, allowing the seat structure 106 to adjust its lateral position so that the patient can choose to train with either the left or right leg.

[0030] In order to enhance the stability and safety of the device, the bottom of the mounting plate 101 can also be provided with an anti-slip pad to prevent the device from sliding or tipping over during use.

[0031] like Figure 2 As shown, in some embodiments, the movable plate 102 is provided with a movable rod 104 inside, and the top of the movable plate 102 is movably connected to a fixing pin 105 through five fixing holes. The movable plate 102 and the movable rod 104 are movably engaged by the fixing pin 105.

[0032] Specifically, the movable rod 104 can slide back and forth inside the movable plate 102 by pulling it, and then the fixing pin 105 limits the total length of the movable rod 104 and the movable plate 102. This allows for adjustment of the gap between the seat structure 106 and the limb placement structure 2 to accommodate different patients' heights and leg lengths, enabling patients to choose a comfortable sitting posture according to their own circumstances.

[0033] like Figure 2 As shown, in some embodiments, a seat structure 106 is fixed to the top of the movable rod 104, the seat cushion and backrest of the seat structure 106 are both soft rubber pads, and a side handle 107 is provided on the side end of the seat structure 106.

[0034] Specifically, the use of soft rubber pads can increase the softness of seat cushions and backrests, reducing fatigue for patients during long training sessions.

[0035] Meanwhile, the side grips 107 of the seat structure 106 are designed to be spacious and easy to hold, so that patients can quickly grab them when needed, avoiding accidental falls during training and thus maintaining body balance.

[0036] like Figure 5 As shown, in some embodiments, the inner sides of the first hinge frame 203 and the second hinge frame 204 are both provided with leg fixing devices 208. The leg fixing device 208 includes a fixing guard 209. The bottom end of the fixing guard 209 is provided with a fitting strap 210, and the top end of the fixing guard 209 is provided with a fixing strap 211.

[0037] Specifically, the fitting strap 210 and the fixing strap 211 can flexibly fix the patient's leg, ensuring that the patient's leg will not shake due to movement during rehabilitation training, thus enhancing the stability and safety of the device.

[0038] like Figure 5 As shown, in some embodiments, the inner side of the fixing guard 209 is provided with a fitting pad, which is a buffer silicone pad, and the fitting strap 210 and the fixing strap 211 are both composed of a Velcro main strap and a Velcro sub strap.

[0039] Specifically, the inner pad of the fixation brace 209 is made of cushioning silicone, which not only increases the patient's comfort but also reduces the pressure caused by prolonged fixation to a certain extent.

[0040] In addition, the Velcro design makes it easy and quick to fix and loosen the adhesive bandage 210 and the fixing bandage 211, making it convenient for medical staff or patients' families to make adjustments according to the patient's specific situation.

[0041] like Figure 6 As shown, in some embodiments, the adjustable counterweight structure 3 includes a gantry frame 301, a base plate 302 is fixedly installed at the bottom end of the gantry frame 301, a slide rail 303 is fixedly installed on the front side of the base plate 302, a slider 305 is slidably connected to the top end of the slide rail 303, and the top end of the slider 305 is fixedly connected to the bottom end of the hinge block 207.

[0042] Specifically, the sliding of the slider 305 on the slide rail 303 can drive the hinge block 207 to move in the front and back direction, and then through the linkage of the follower frame 206 and the second hinge frame 204, the intensity of the flexion and extension training of the patient's ankle joint can be adjusted.

[0043] Furthermore, a scale is provided on the slide rail 303, which corresponds to the position of the slider 305. This scale can intuitively display the movement distance of the slider 305, thereby helping medical staff or patients' families to accurately grasp the training intensity and ensure the scientific nature and effectiveness of rehabilitation training.

[0044] like Figure 6 As shown, in some embodiments, a first transmission wheel 304 is rotatably connected to the front side of the slide rail 303, a second transmission wheel 306 is rotatably connected to the top of the base plate 302, a sliding vertical rod 307 is fixedly connected to the inner side of the gantry frame 301, and a follower counterweight 308 and a movable counterweight 311 are slidably connected to the surface of the sliding vertical rod 307.

[0045] Specifically, medical staff or patients' families can precisely control the training intensity by adjusting the position and number of the follow-up counterweight 308 and the movable counterweight 311, based on the patient's recovery progress and physical condition. This design not only improves the targeting and effectiveness of training but also enhances the patient's rehabilitation experience and comfort.

[0046] The follow-up counterweight 308 is connected to the slider 305 via the lifting rope 309, ensuring that the follow-up counterweight 308 can automatically adjust its position as the slider 305 moves, thereby maintaining the stability and continuity of training.

[0047] like Figure 7 As shown, in some embodiments, a plug rod 310 is fixedly installed on the inner side of the follower counterweight 308, and a lifting rope 309 is wound around the top of the plug rod 310. The other end of the lifting rope 309 is connected to the front end of the slider 305 in sequence through the second transmission wheel 306 and the first transmission wheel 304.

[0048] Specifically, the lifting rope 309, guided by the second transmission wheel 306 and the first transmission wheel 304, can smoothly pull the follower counterweight 308 to move, ensuring a smooth transition of the counterweight during training and avoiding training instability caused by sudden changes in the counterweight.

[0049] like Figure 8 As shown, in some embodiments, a lifting block is fixedly sleeved on the surface of the sliding vertical rod 307, the bottom end of the movable counterweight 311 overlaps with the top end of the lifting block, the interior of the movable counterweight 311 is provided with a plug interface adapted to the plug rod 310, and the movable counterweight 311 and the plug rod 310 are movably engaged by a plug pin 312.

[0050] Specifically, the plug-in design between the movable counterweight 311 and the plug-in rod 310 makes it simple and quick to add or remove the movable counterweight 311.

[0051] Medical staff or patients' family members can adjust the connection relationship between the follow-up counterweight 308 and the movable counterweight 311 simply by pulling the plug pin 312 out of the plug interface, thereby achieving rapid adjustment of the training intensity.

[0052] When in use, first measure the patient's height, then adjust the front and back position of the seat structure 106 according to the patient's height. By pulling the movable rod 104, it can slide back and forth inside the movable plate 102. Then, the fixing pin 105 limits the total length of the movable rod 104 and the movable plate 102. This allows for adjustment of the gap between the seat structure 106 and the limb placement structure 2 to accommodate different patients' heights and leg lengths, enabling patients to choose a comfortable sitting posture according to their own circumstances. Next, depending on the leg position that the patient needs to train, the seat structure 106 is selected to be biased to the left or right. The position of the seat structure 106 is adjusted by adjusting the sliding plate 102 inside the mounting plate 101, so that the seat structure 106 can adjust its own lateral position, thereby allowing the patient to choose to train with the left or right leg. Next, have the patient sit on the seat structure 106, place the lower limbs into the leg fixation device 208, and fix the legs using the fitting strap 210 and the fixing strap 211. Then, medical staff or patients' families can adjust the connection relationship between the follow-up counterweight 308 and the movable counterweight 311 by inserting or disconnecting the plug pin 312 and the plug rod 310, according to the patient's recovery progress and physical condition, in order to set a suitable training intensity.

[0053] At the start of training, the patient uses the strength of their leg muscles to move the foot contact plate 205 in a flexion and extension motion. This motion is transmitted to the hinge block 207 through the second hinge frame 204 and the follower frame 206, which in turn causes the slider 305 to slide on the slide rail 303. The movement of the slider 305 will pull the follower counterweight 308 and the movable counterweight 311 through the lifting rope 309, thereby achieving the effect of training the ankle joint.

[0054] Throughout the training process, medical staff or patients' families can visually grasp the training intensity by observing the position of slider 305 on the scale and make appropriate adjustments as needed.

[0055] In summary, through the limb placement structure 2 and the adjustable weight structure 3, the limb placement structure 2 can effectively fix the patient's lower limbs, ensuring stability while allowing for flexible flexion and extension movements of the knee and ankle joints, thereby promoting blood circulation and joint function recovery. Combined with the adjustable weight structure 3, the training intensity can be specifically adjusted according to the patient's specific recovery level, making the rehabilitation training process more scientific and reasonable. Through this gradual approach, the patient's rehabilitation training can not only progress steadily but also effectively avoid secondary injuries caused by inappropriate training intensity, ensuring maximum rehabilitation effectiveness.
