Description

Technical Field

[0001] This invention relates to the field of rehabilitation training equipment, and in particular to an ankle joint rehabilitation training device. Background Technology

[0002] The ankle joint is composed of the tibia, fibula, and talus. It is a hinge joint that mainly bears weight and requires both stability and flexibility during movement.

[0003] With the increasing aging of society, the number of stroke patients has increased dramatically. Postoperative outcomes for stroke patients are poor, and a high proportion of patients also suffer from ankle dysfunction, such as foot drop.

[0004] A significant factor contributing to ankle dysfunction is damage to the central nervous system. Correspondingly, the fundamental goal of rehabilitation training is to stimulate the rebuilding and compensation of the central nervous system, promote the recovery of motor perception function, and ultimately restore ankle motor function. Therefore, after an ankle injury, in addition to medication, rehabilitation training is necessary to improve rehabilitation efficiency.

[0005] Because ankle dysfunction causes different movement disorders in different people, targeted and progressively matched training methods are needed to better help patients recover. However, due to the limited number of rehabilitation physicians and the inconvenience of going to rehabilitation clinics for rehabilitation training, a home-based device that allows for rehabilitation training at any time according to the patient's condition is particularly important and can greatly promote the patient's recovery. Summary of the Invention

[0006] Therefore, it is necessary to provide an ankle joint rehabilitation training device that can be used independently at home and can be used for rehabilitation training according to the patient's condition, in order to address the above-mentioned technical problems.

[0007] An ankle joint rehabilitation training device, comprising:

[0008] Trainer framework;

[0009] A leg support bracket is fixed to one end of the trainer frame;

[0010] A leg rest is installed at the top of the leg rest bracket;

[0011] A footrest is located within the frame of the trainer, and one end of the footrest is hinged to the leg support bracket;

[0012] An adjustable airbag is located between the trainer frame and the footrest, used to lift or release the footrest to cause the footrest to undulate and rotate.

[0013] The training device host is used for inputting user setting parameters and driving inflation or contraction of the adjustable air bag according to the user setting parameters.

[0014] In one of the embodiments, the leg support bracket comprises:

[0015] A leg support sleeve is fixed at one end of the training device frame;

[0016] A leg support stand is installed at the other end of the leg support sleeve, and the leg support stand is movable relative to the leg support sleeve and fixed in the leg support sleeve.

[0017] In one of the embodiments, a through hole is formed in the leg support sleeve, and a plurality of positioning holes are formed in the leg support stand along the central axis direction and are spaced apart from each other, and the central axis of the positioning holes is parallel to the central axis of the through hole.

[0018] In one of the embodiments, the leg support is arranged in an arc-shaped plate structure, one side of the leg support has a limiting slot, and the other side of the leg support is hinged to the top end of the leg support stand.

[0019] In one of the embodiments, an angle feedback device is fixed on the side of the training device frame, a detection end of the angle feedback device is connected to one end of the leg support sleeve connected with the foot support, and the angle feedback device is used to obtain the rotation angle of the foot support.

[0020] In one of the embodiments, the training device host comprises:

[0021] A gas path integration unit is connected to one end of the adjustable air bag;

[0022] A gas path output unit is connected to one end of the gas path integration unit, and is used to supply gas to the adjustable air bag, so that the adjustable air bag supports or releases the foot support;

[0023] An integrated control unit is electrically connected to the gas path output unit and the angle feedback device, and is used to control the gas path output unit according to the user setting parameters and the rotation angle of the foot support fed back by the angle feedback device;

[0024] A power supply output unit is electrically connected to the integrated control unit, and is used to supply power to the integrated control unit;

[0025] A display unit is electrically connected to the integrated control unit, and is used to display the opening state of the integrated control unit.

[0026] In one of the embodiments, the training device further comprises an emergency stop remote controller, the emergency stop remote controller is communicatively connected to the integrated control unit, and is used to send a stop instruction to the integrated control unit, so that the integrated control unit controls the gas path output unit to stop running.

[0027] In one embodiment, the trainer further includes a power adapter connected to the mains power supply and the power output unit.

[0028] In one embodiment, a base is fixed at the bottom of the trainer frame, and the adjustable airbag is located between the base and the footrest.

[0029] In one embodiment, the adjustable airbag is an accordion-style adjustable airbag.

[0030] In use of the aforementioned ankle joint rehabilitation trainer, the patient places their foot on the footrest and rests their lower leg on the leg rest, ensuring the foot and lower leg are in contact with the footrest and leg rest respectively. The leg rest height is then adjusted according to the individual's lower leg length to move it to a suitable position. Next, the settings are input into the trainer's main unit, causing the adjustable airbag to lift or release the footrest according to the user's input, resulting in a rising and falling motion of the footrest. During this process, the trainer's main unit repeatedly supplies and deflates the adjustable airbag to change the angle between the patient's ankle joint and lower leg, thus achieving ankle rehabilitation training. This ankle joint rehabilitation trainer can be used independently at home, and the user can individually set the parameters of the main unit according to the patient's condition, thereby conducting rehabilitation training for the patient.

[0045] The following is combined Figures 1-6 This invention describes an ankle joint rehabilitation training device.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, an ankle rehabilitation trainer includes a trainer frame 100, a leg support bracket 600, a leg support 700, a foot support 400, an adjustable airbag 500, and a training device. Apparatus The main unit 800 is a leg support bracket 600 fixed to one end of the trainer frame 100; a leg support 700 is mounted on the top of the leg support bracket 600; a foot support 400 is located inside the trainer frame 100, and one end of the foot support 400 is hinged to the leg support bracket 600; an adjustable airbag 500 is located between the trainer frame 100 and the foot support 400, used to lift or release the foot support 400 so that the foot support 400 can undulate and rotate; the main unit 800 is used to input user-set parameters and drive the expansion or contraction of the adjustable airbag 500 according to the user-set parameters.

[0047] In use of the aforementioned ankle joint rehabilitation trainer, the patient places their foot on the footrest 400 and rests their lower leg on the leg rest 700, ensuring the foot and lower leg are in contact with the footrest 400 and leg rest 700 respectively. The height of the leg rest bracket 600 is then adjusted according to the individual's lower leg length to move the leg rest 700 to a suitable position. Subsequently, setting parameters are input into the trainer's main unit 800, causing the adjustable airbag 500 to lift or release the footrest 400 according to the user-input parameters, resulting in the footrest 400's up-and-down rotation. During this process, the trainer's main unit 800 repeatedly supplies and deflates the adjustable airbag 500 to change the angle between the patient's ankle joint and lower leg, thus achieving ankle rehabilitation training. This ankle joint rehabilitation trainer can be used independently at home, and users can individually set the parameters of the trainer's main unit 800 according to the patient's condition, thereby conducting rehabilitation training for the patient.

[0048] In one embodiment, the leg support bracket 600 includes a leg support sleeve 610 and a push-off upright; one end of the leg support sleeve 610 is fixed to one end of the trainer frame 100; the leg support upright 620 is installed at the other end of the leg support sleeve 610, and the leg support upright 620 can move relative to the leg support sleeve 610 and be fixed inside the leg support sleeve 610.

[0049] Specifically, because patients have different ages, calf lengths, and calves, the fixed-position leg support stand 620 cannot adjust the height of the leg support 700, thus preventing the leg support 700 from fitting the patient's calf more closely. This can affect the patient's ankle joint mobility during rehabilitation training and is not conducive to the patient's ankle joint rehabilitation training.

[0050] like Figure 3 As shown, in one embodiment, the leg support sleeve 610 has a through hole 611, and the leg support upright 620 has a plurality of positioning holes 621 spaced apart along the central axis direction, the central axis of the positioning hole 621 being parallel to the central axis of the through hole 611.

[0051] Specifically, when adjusting the height of the leg support 700, drag the leg support upright 620 along the central axis of the leg support sleeve 610 and stop at the appropriate height. Since the leg support upright 620 has multiple spaced positioning holes 621, and the central axis of the positioning holes 621 is parallel to the central axis of the through hole 611, when the leg support upright 620 is moved to the appropriate position, there will always be a positioning hole 621 that is opposite to or close to the through hole 611. At this time, fasteners can be inserted into the through hole 611 and the positioning hole 621 that is opposite to or close to the through hole 611 in sequence to fix the height of the leg support 700.

[0052] The leg support sleeve 610 and the leg support upright 620 can be fixed by bolts, pins, ball bearings, etc. The leg support upright 620 preferably has five positioning holes 621, which can be adjusted to a height of 80 mm, with each section adjusting the height by 20 mm.

[0053] In one embodiment, the leg support 700 is provided with an arc-shaped plate structure, one side of the leg support 700 has a limiting groove 710, and the other side of the leg support 700 is hinged to the top of the leg support upright 620.

[0054] Specifically, the arc-shaped plate structure is used to limit the patient's lower leg. Furthermore, one side of the leg support 700 is hinged to the top of the leg support upright 620, with the hinge axis horizontal. The rotation angle between the two is adjustable from 0 to 360 degrees, allowing the leg support 700 to rotate within a certain range as the patient's ankle joint moves with the foot support 400. This enables the patient's leg to adjust according to the ankle joint posture during ankle rehabilitation training, making the trainer more versatile.

[0055] like Figure 5 As shown, in one embodiment, the top diameter of the limiting slot 710 is larger than the bottom diameter, and an elastic buffer pad is provided on the surface of the limiting slot 710.

[0056] Specifically, since the human calf is thicker at the top and thinner at the bottom, the top diameter of the limiting groove 710 is set larger than the bottom diameter so that the contour of the patient's calf can match the shape of the limiting groove 710. An elastic cushioning pad is provided on the surface of the limiting groove 710, allowing the patient's calf to fit snugly within the limiting groove 710 and preventing movement of the patient's leg within the leg support 700. The elastic cushioning pad is made of elastic materials such as rubber or silicone.

[0057] In one embodiment, an angle feedback device 300 is fixed to the side of the trainer frame 100. The detection end of the angle feedback device 300 is connected to one end of the leg support sleeve 610 of the foot support 400 to obtain the rotation angle of the foot support 400.

[0058] Specifically, since the angle feedback device 300 is fixed to the side of the trainer frame 100, and the detection end of the angle feedback device 300 is also connected to the end of the footrest 400 that is hinged to the leg support sleeve 610, that is, connected to the footrest 400. The rotation angle of the footrest 400 can present different angles according to the inflation amount of the adjustable airbag 500. When the footrest 400 rotates under the influence of the adjustable airbag 500, the detection end of the angle feedback device 300 will detect the rotation angle of the footrest 400 in real time.

[0059] In one embodiment, a base 200 is fixed to the bottom of the trainer frame 100, and an adjustable airbag 500 is located between the base 200 and the footrest 400. The adjustable airbag 500 is an accordion-style adjustable airbag 500.

[0060] Specifically, the end of the accordion-style adjustable airbag 500 is fixed to the base 200 by fasteners. One side of the deployed end of the accordion-style adjustable airbag 500 is fixed to the base 200, and the other side is fixed to the footrest 400 by fasteners.

[0061] In one embodiment, the base 200 is connected to the trainer frame 100 via a torque limiter. Normally, the base 200 is parallel to the ground. When fine-tuning is required, the torque limiter can be manually adjusted to change the angle between the base 200 and the ground from 0 to 45 degrees.

[0062] like Figure 4 As shown, in one embodiment, the footrest 400 includes a base plate 410 and a sliding plate 420; one end of the base plate 410 is hinged to the leg support sleeve 610, and a groove is provided on the upper surface of the base plate 410. The sliding plate 420 is movably engaged in the groove, and the sliding plate 420 can move along the length direction of the base plate 410.

[0063] The slide plate 420 and the base plate 410 are connected by a movable part 430, which is a spherical or rod-shaped structure with rolling capability.

[0064] Specifically, the length direction of the base plate 410 is the direction in which the patient's toes point when placing their foot on the footrest 400. When the patient's foot is placed on the surface of the skateboard 420, the base plate 410 rotates due to the influence of the adjustable airbag 500, and the patient's ankle joint also moves accordingly. If the relative position between the patient's foot and the base plate 410 and the relative position between the patient's lower leg and the footrest 700 remains unchanged, then after the ankle joint moves, the contact area between the patient's foot and lower leg and the training device will become tight, affecting the training effect in the patient's natural state.

[0065] The leg support sleeve 610 has straps 630 connected to both ends on both sides to limit the patient's ankle joint and make it fit as closely as possible to the hinge of the base plate 410 and the leg support sleeve 610. This, together with the movable skateboard 420, can achieve better rehabilitation training results.

[0066] In one embodiment, the trainer host 800 includes an air path integration unit 830, an air path output unit 840, an integrated control unit 820, a power output unit 850, and a display unit 810. One end of the air path integration unit 830 is connected to an adjustable airbag 500. One end of the air path output unit 840 is connected to the air path integration unit 830 and is used to supply air to the adjustable airbag 500 so that the adjustable airbag 500 can lift or release the footrest 400. The integrated control unit 820 is electrically connected to the air path output unit 840 and the angle feedback device 300 and is used to control the air path output unit 840 according to user-set parameters and the rotation angle of the footrest 400 fed back by the angle feedback device 300. The power output unit 850 is electrically connected to the integrated control unit 820 and is used to supply power to the integrated control unit 820. The display unit 810 is electrically connected to the integrated control unit 820 and is used to display the on / off status of the integrated control unit 820.

[0067] Specifically, pressing the rocker switch on the power output unit 850 illuminates the indicator light on the display unit 810. User-defined parameters include starting movement speed, training time, and training angle. After confirming the settings, the trainer host 800 is started. During rehabilitation training, the trainer host 800 restarts the accordion-style adjustable airbag 500. As the gas volume within the adjustable airbag 500 increases, the angle between the footrest 400 and the ground changes, i.e., the angle between the patient's ankle joint and lower leg changes. The angle feedback device 300 also feeds this angle back to the integrated control unit 820, and the display unit 810 displays this feedback angle. When the patient reaches their limit position, the footrest 400 remains stationary for three seconds. The integrated control unit 820 records this angle and then presses the HOLD button, holding the position for three seconds. This angle will be used as the maximum value in subsequent training sessions. After training, the adjustable airbag 500 deflates, and the training process is repeated.

[0068] Because the above training process is repeated every time, the patient's recovery can be tracked in real time to adjust the training angle, and the patient can complete the rehabilitation training independently when alone, saving manpower.

[0069] In one embodiment, the trainer also includes an emergency stop remote controller, which is communicatively connected to the integrated control unit 820 and is used to send a stop command to the integrated control unit 820 so that the integrated control unit 820 controls the air circuit output unit 840 to stop operating.

[0070] In one embodiment, the trainer further includes a power adapter connected to a mains power supply and a power output unit 850.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
