Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a leg rehabilitation exercise device that is convenient for family use. Background Art

[0002] Rehabilitation is a medical or rehabilitative procedure designed to restore or train the function of a limb, especially after injury or surgery. Rehabilitation aims to minimize or eliminate impairments in physical function and help the patient return to a level of health and function close to their normal state.

[0003] At present, rehabilitation training for foot injuries (such as ligament rupture, fracture, etc.) often relies on professional equipment in hospitals and the guidance of rehabilitation therapists. It is difficult to provide more rehabilitation treatment at home, and patients need to frequently travel to and from the hospital. Since patients have difficulty in moving and unbearable pain in the early stages of the disease, frequent travel to and from the hospital can easily aggravate physical pain and increase psychological burden. It can also affect the rehabilitation process and even cause secondary injuries due to running around. At the same time, in the later stages of the disease, it is difficult for patients to conduct rehabilitation training independently at home, which will lead to delayed rehabilitation progress, aggravated muscle atrophy or joint adhesions, and affect the final rehabilitation effect.

Detailed implementation manners

[0034] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0036] Referring to Figures 1 - 11 , a leg rehabilitation exercise device convenient for home use, including a rehabilitation chair 1, a rehabilitation training component is provided on one side of the rehabilitation chair 1, and a control panel 33 is provided on one side of the rehabilitation chair 1;

[0037] The rehabilitation training component includes a thigh bracket 2, a calf bracket 3 and a foot bracket 4. The numbers of the thigh bracket 2, the calf bracket 3 and the foot bracket 4 are all set to two. The rehabilitation training component further includes an automatic training unit and an independent training unit. The automatic training unit includes a hydraulic rod 8, and the hydraulic rod 8 is used for training the patient's legs. The independent training unit includes a friction disc 17 and a friction plate 22, and the friction disc 17 and the friction plate 22 are used to adjust the intensity of independent training.

[0038] The overall leg rehabilitation exercise device has two modes: an automatic training mode and an independent training mode. In this way, the full-stage home rehabilitation needs of patients from the initial stage of illness to the late stage of recovery can be met. In the initial stage, through the automatic training mode, the patient does not need to exert force actively, and can achieve passive and precise rehabilitation exercises at home with the help of the hydraulic rod 8, avoiding the risks brought by going back and forth to the hospital or improper self-operation. And in the later stage, it switches to the independent training mode, and the intensity is adjusted by using the frictional resistance. The patient can independently adjust the training intensity at home according to the recovery situation, and gradually restore muscle strength and joint function. This dual-mode makes home rehabilitation more continuous and flexible, reduces the dependence on professional places and personnel, and significantly improves the efficiency and convenience of home rehabilitation.

[0039] Reference Figures 1 - 4 and Figure 10 One end of each of the two thigh brackets 2 is fixedly connected to both sides of the rehabilitation chair 1. One end of each of the two calf brackets 3 is rotatably connected to one side of the corresponding thigh bracket 2. A connecting block 5 is fixedly connected to one end of each of the two calf brackets 3 away from the thigh bracket 2. Each of the two foot brackets 4 is rotatably connected to one end of the corresponding calf bracket 3. A fixed box 6 is fixedly connected to the bottom of one side of the rehabilitation chair 1. A support plate 7 is provided on one side of the fixed box 6. A hydraulic rod 8 is rotatably connected inside the fixed box 6. A connecting plate 9 is fixedly connected between the two calf brackets 3. A chute 10 is formed on one side of the connecting plate 9. The output end of the hydraulic rod 8 is rotatably connected to a connecting seat 11. A slider 12 is slidably connected inside the chute 10. The connecting seat 11 and the slider 12 are electromagnetically connected.

[0040] Through the automatic training unit, the legs can be automatically trained at the initial stage of the patient's illness, so as to realize the states of raising, laying flat and normal vertical to the ground of the legs. The specific active training method is as follows: before the automatic training, the patient first sits on the rehabilitation chair 1, places the legs steadily on the two thigh brackets 2 on both sides respectively, bends the knees naturally and fits them to the rotation connection between the thigh bracket 2 and the calf bracket 3, and gently places the feet on the foot brackets 4. Then, set the training parameters on the control panel 33, and start the hydraulic rod 8 in the fixed box 6 through the control panel 33. The connecting seat 11 at the output end of the hydraulic rod 8 and the slider 12 in the chute 10 of the connecting plate 9 are electromagnetically connected to form a stable transmission structure;

[0041] When the hydraulic rod 8 extends, it drives the connecting seat 11 and the slider 12 to slide in the chute 10, pulls the connecting plate 9 and pushes the calf bracket 3 to swing upward around the rotation point of the thigh bracket 2, and the foot bracket 4 moves accordingly to realize the raising of the leg;

[0042] When the hydraulic rod 8 shortens, the calf bracket 3 falls back under the action of gravity and the pulling force of the hydraulic rod 8, so that the leg is laid flat (as Figure 4 shown);

[0043] By precisely controlling the telescopic length and angle of the hydraulic rod 8, the calf bracket 3 can also drive the leg to keep in a state perpendicular to the ground (as Figure 1 shown). During the whole process, the hydraulic rod 8 adjusts the telescopic force and speed according to the preset program, which can not only avoid secondary injuries caused by the patient's own weakness or loss of control, but also promote blood circulation in the legs, maintain muscle activity and gradually restore joint mobility through regular passive movement.

[0044] The automatic training unit can provide safe, scientific and convenient rehabilitation training for foot injury patients in the initial stage of the disease. Through the automated motion mode driven by the hydraulic rod 8, the elevation, horizontal placement and vertical state of the leg can be accurately controlled, avoiding secondary injuries caused by the patient's difficulty in active exertion or improper movements. Moreover, through regular passive movements, it can effectively promote blood circulation in the leg, prevent muscle atrophy and joint stiffness, and accelerate the rehabilitation process. In addition, patients do not need to go to the hospital frequently and can complete the rehabilitation training in the home environment, which not only saves time and economic costs, but also reduces the physical and mental burden brought by traveling back and forth. At the same time, the parameter setting function of the control panel 33 can also flexibly adjust the training intensity and method according to the individual differences and recovery stages of the patients, truly realizing personalized rehabilitation treatment.

[0045] Referring to Figures 1 - 7 , side plates 13 are provided on both sides of the rehabilitation chair 1. A first rotating shaft 14 is rotatably connected to one side of each of the two side plates 13 close to the thigh bracket 2. Each first rotating shaft 14 passes through the corresponding thigh bracket 2 and is fixedly connected to the corresponding calf bracket 3. A second rotating shaft 15 is rotatably connected to both sides of each support plate 7. A transmission wheel 16 is fixedly connected to the outer wall of each second rotating shaft 15 and the first rotating shaft 14. Every two transmission wheels 16 are connected by a belt drive. Each friction disc 17 is respectively arranged on the outer wall of the corresponding second rotating shaft 15. Cavities are formed inside both side plates 13. A first motor 18 is provided on one side of each of the two side plates 13. A bidirectional threaded rod 19 is rotatably connected inside each of the two side plates 13. The output end of each first motor 18 passes through one side of the side plate 13 and is fixedly connected to the corresponding bidirectional threaded rod 19. Moving blocks 20 are threadedly connected to both sides of the outer wall of each bidirectional threaded rod 19. A limiting hole 21 is formed on one side of each side plate 13. Each moving block 20 is respectively slidably connected to the corresponding limiting hole 21. Each friction plate 22 is fixedly connected to one end of the corresponding moving block 20 extending outside the side plate 13. Every two friction plates 22 are respectively located on both sides of the corresponding friction disc 17.

[0046] Through the active training unit, the patient can perform self-rehabilitation exercises in the later stage of the illness and can adjust the training intensity according to their own rehabilitation situation. The specific training method is as follows: First, on the control panel 33, adjust the automatic training mode to the autonomous training mode. Since the connecting seat 11 and the slider 12 are electromagnetically connected, after adjusting to the autonomous training mode, the connecting seat 11 and the slider 12 will be disconnected. Then, start the first motor 18 located on one side of the two side plates 13 through the control panel 33. The first motor 18 drives the bidirectional threaded rod 19 to rotate, so that the moving blocks 20 threadedly connected to both sides of the outer wall of the bidirectional threaded rod 19 move towards each other under the restriction of the limiting holes 21, thereby driving the friction plates 22 fixed at one end of the moving blocks 20 extending outside the side plates 13 to approach the friction disc 17. By adjusting the clamping degree between the two friction plates 22 and the friction disc 17, the friction force between the friction plates 22 and the friction disc 17 is adjusted to achieve the adjustment of the training intensity;

[0047] When the patient actively flexes and extends the leg, the calf bracket 3 rotates around the first rotating shaft 14. Through the transmission wheels 16 fixed on the outer walls of the first rotating shaft 14 and the second rotating shaft 15 and the belt connecting them, the second rotating shaft 15 is driven to rotate, and then the friction disc 17 fixed on the outer wall of the second rotating shaft 15 rotates accordingly. At this time, the friction force between the friction disc 17 and the friction plate 22 will generate resistance to the patient's autonomous movement. The greater the friction force, the greater the force the patient needs to exert, and the higher the training intensity;

[0048] In this way, the patient can, according to their own rehabilitation situation, control the first motor 18 through the control panel 33 to precisely adjust the clamping force between the friction plate 22 and the friction disc 17, thereby flexibly adjusting the training intensity, achieving personalized rehabilitation training, and gradually restoring the leg muscle strength and joint function.

[0049] Through the autonomous training unit, the patient can independently control the training process in the later stage of rehabilitation, achieve a smooth transition from passive recovery to active strengthening. The separation design of the electromagnetic connection makes the training mode switching convenient and safe, avoiding mechanical interference between automatic and autonomous training. Moreover, through the setting of adjustable resistance between the friction plate 22 and the friction disc 17, the training intensity can be accurately matched according to the patient's muscle strength recovery situation, preventing secondary injuries caused by excessive force and effectively promoting muscle strength reconstruction through progressive resistance training. At the same time, through the linkage structure of the transmission wheel 16 and the belt, the leg movement is converted into stable resistance feedback, simulating the joint movement trajectory during real walking, which helps to restore the normal gait. In addition, the ability to perform autonomous training in a home environment not only continues the convenience of early automatic training but also enhances the patient's rehabilitation confidence through active participation.

[0050] Refer to Figures 4 - 9, a third rotating shaft 23 is provided on one side of each connecting block 5. Each third rotating shaft 23 is rotatably connected to the corresponding connecting block 5. After each third rotating shaft 23 passes through the corresponding connecting block 5, it is fixedly connected to one side of the corresponding foot support 4. One end of each third rotating shaft 23 is fixedly connected to a first gear 24. Limit tracks 25 are fixedly connected to both sides of the rehabilitation chair 1. A limit post 26 is provided on one side of each calf support 3. Each limit post 26 is slidably connected to the corresponding limit track 25. A bottom plate 27 is fixedly connected to one side of each limit track 25. A second motor 28 is provided on the top of each bottom plate 27. A second gear 29 is provided at the output end of each second motor 28.

[0051] Through the arrangement of the first gear 24 and the second gear 29, when laser treatment is needed, the patient's feet can be adjusted to a non-support state and can be used in cooperation with the overall rehabilitation device. The specific operation method is as follows: when laser treatment is needed, first, in the automatic training mode, adjust the legs to the flat state (as Figure 4 shown). At this time, the first gear 24 will be exactly in the meshed state with the second gear 29. Start the second motor 28 through the control panel 33 to drive the second gear 29 to rotate. Since the first gear 24 and the second gear 29 are in the meshed state at this time, the rotation of the second gear 29 will drive the first gear 24 to rotate synchronously. Then, the third rotating shaft 23 fixed on the same axis as the first gear 24 rotates. The rotation of the third rotating shaft 23 will drive the foot support 4 fixedly connected thereto to make a circular motion around the third rotating shaft 23, so that the patient's foot support 4 rotates 180 degrees and gradually adjusts from the flat state to the non-support state. After the foot is adjusted to the non-support position, the laser treatment device (the laser treatment device is a prior art and is not shown in the figure) can be moved to the patient's ankle, and then start the laser treatment device to perform targeted treatment on the foot;

[0052] After the treatment is over, start the second motor 28 in the reverse direction to turn the foot support 4 back to the initial position, and the patient can continue with the regular leg rehabilitation training.

[0053] By being used in cooperation with laser treatment, it can significantly improve the convenience and comfort of rehabilitation treatment. In this way, the patient does not need to move the legs or body by himself during the treatment process, and can accurately adjust the feet to the appropriate non-support state, reducing the risk of increased pain or secondary injury caused by posture change. At the same time, there is no need to transfer to different treatment instruments repeatedly, which greatly saves the treatment time, reduces the physical burden, helps the patient receive efficient treatment in a stable and comfortable state, and accelerates the rehabilitation process.

[0054] Refer to Figures 1 - 5 , a placement groove 30 is provided on one side of each thigh support 2, calf support 3 and foot support 4. A massage air cushion pad 31 is provided on one side of each placement groove 30. A connection head 32 is provided on one side of each massage air cushion pad 31.

[0055] Among them, the surface of the massage airbag pad 31 is provided with Velcro, which can be fixed to adapt to the leg sizes of different patients, and the connector 32 can be docked with a pneumatic therapy device (the pneumatic therapy device is a prior art and not shown in the figure) before massage.

[0056] Through the setting of the massage airbag pad 31, the legs can be massaged during the leg rehabilitation training of the patient. The specific operation method is as follows: First, after the patient places both legs on the thigh support 2, the calf support 3 and the foot support 4, according to the leg size of the patient, adjust through the Velcro on the surface of the massage airbag pad 31 to make it fit closely to the legs to ensure the massage effect. Subsequently, dock the connector 32 on one side of the massage airbag pad 31 with a pneumatic therapy device (the pneumatic therapy device is a prior art and will not be elaborated here). After starting the pneumatic therapy device through the control panel 33, during the operation of the device, it will inflate and deflate the massage airbag pad 31, causing the airbag pad to expand and contract rhythmically, so as to perform a wrapped massage on the limb, promote blood circulation, and accelerate the return of venous blood and tissue fluid;

[0057] In the autonomous training mode, when the patient actively flexes and extends the legs, the dynamic extrusion of the massage airbag pad 31 can further enhance the flexibility of joint activities and reduce the discomfort during the rehabilitation training. During the massage process, the pneumatic therapy device can adjust the air pressure magnitude, massage frequency and time according to the patient's needs to achieve a personalized massage experience, effectively improving the effect of the rehabilitation training. After the training is over, just disconnect the docking of the connector 32 and the pneumatic therapy device.

[0058] The wrapped massage achieved through the cooperation of the massage airbag pad 31 and the pneumatic therapy device can promote blood circulation during the training process, accelerate the return of venous blood and tissue fluid, effectively reduce leg swelling and pain, relieve muscle fatigue, create good physiological conditions for the rehabilitation training, and in the autonomous training mode, with the assistance of the dynamic extrusion of the massage airbag pad 31, it not only helps to enhance joint flexibility, but also can reduce the discomfort brought by the training and improve the enthusiasm and compliance of the patient's training.

[0059] Working principle: When the patient uses this leg rehabilitation exercise device, first sit on the rehabilitation chair 1, place both legs stably on the thigh support 2, the calf support 3 and the foot support 4, adjust the fitting degree through the Velcro on the surface of the massage airbag pad 31, and dock the connector 32 with the pneumatic therapy device (if massage is needed);

[0060] If in the initial stage of the disease, select the automatic training mode on the control panel 33, set the training parameters of the hydraulic rod 8 (such as telescopic speed, strength, angle), and after starting, the hydraulic rod 8 drives the linkage of the connecting seat 11 and the slider 12, driving the calf support 3 and the foot support 4 to move, so as to realize training actions such as leg elevation, flat placement, and verticality;

[0061] If entering the late stage of rehabilitation, switch to the autonomous training mode on the control panel 33, disconnect the electromagnetic connection between the connecting seat 11 and the slider 12, start the first motor 18 to adjust the clamping force between the friction plate 22 and the friction disc 17, customize the training intensity, and complete the rehabilitation training by actively flexing and extending the legs;

[0062] When laser treatment is required, first adjust the leg to a flat state in the automatic training mode, engage the first gear 24 with the second gear 29, start the second motor 28 to drive the foot support 4 to rotate 180 degrees to a non-support state, and reverse the operation to restore the initial position after the treatment;

[0063] During the whole training process, the pneumatic treatment device can be started as needed to let the massage airbag pad 31 perform wrapped massage, improving the rehabilitation experience and effect.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
