Description

Technical Field

[0001] This application relates to the field of rehabilitation technology, and more specifically, to a lower limb training and rehabilitation device. Background Technology

[0002] Lower limb fractures take a relatively long time to heal, generally around three months. During the recovery period after bone setting, rehabilitation exercises are usually required to improve knee joint mobility and prevent muscle and joint adhesions.

[0003] In related technologies, a common approach is to install a swinging board on the wheelchair to drive the patient's legs to swing for training. However, patients can only rely on the swinging board for passive training and cannot perform active leg rehabilitation exercises. Utility Model Content

[0004] In order to at least overcome some of the deficiencies in the related technologies, this application provides a lower limb training and rehabilitation device.

[0005] To achieve the above objectives, this application provides a lower limb training and rehabilitation device, including a seat and a training assembly. The seat has a seat surface. The training assembly includes a training plate hinged to the edge of the seat surface; a passive training section and an active training section are disposed on the seat facing the training plate. The passive training section includes a pushing member, the output end of which is detachably abutted against the end of the training plate away from the seat surface, for pushing the training plate to swing. The active training section includes a first elastic member disposed between the training plate and the seat; when the output end of the pushing member is connected to the training plate, the first elastic member is in a compressed state.

[0006] Furthermore, the training board includes a first plate and a second plate for fixing and supporting the patient's lower limbs. The first plate is hinged to the seat surface. A cavity is formed on the first plate extending from one end away from the seat surface towards the seat surface. The second plate is slidably installed in the cavity, and the second plate can be fixed relative to the first plate.

[0007] Furthermore, a third plate is hinged to one end of the second plate away from the first plate to fix and support the patient's foot. A telescopic rod is provided between the second plate and the third plate, and a second elastic element is provided on the telescopic rod to limit the extension or retraction of the telescopic rod.

[0008] Furthermore, a first connecting end is provided on the side of the second plate facing the pusher; one end of the pusher is hinged to the base, the output end of the pusher is the second connecting end, and the second connecting end is detachably installed on the first connecting end.

[0009] Furthermore, the active training unit includes a support frame disposed on the base near the second plate. Multiple first elastic members are evenly distributed between the support frame and the second plate.

[0010] Furthermore, a connector for connecting the second plate is provided at one end of the first elastic member away from the support frame. The connector includes a U-shaped plate, which is disposed at the end of the first elastic member and can be snapped onto the second plate.

[0011] Furthermore, a through groove is formed at one end of the second plate away from the first plate, and a connecting groove is formed on the U-shaped plate, the connecting groove being able to communicate with the through groove. The connector also includes a plug rod, the plug rod passing through the connecting groove and inserted into the through groove.

[0012] Furthermore, a fixing groove is provided at the end of the insertion rod extending into the through groove, a limiting rod is inserted into the fixing groove, and a pull ring is provided on the limiting rod at a position outside the fixing groove.

[0013] Furthermore, a storage compartment is provided on the side of the support frame away from the training board.

[0014] Furthermore, the active training unit also includes a hinge rod, which is hingedly mounted on the base near the first plate. An L-shaped plate is provided at the end of the hinge rod away from the base, the L-shaped plate is attached to the first plate, and a third elastic element is provided between the hinge rod and the L-shaped plate.

[0015] With the above technical solution, when using the lower limb training and rehabilitation device of this application, the patient sits on the seat surface of the seat and places both legs on the training plate of the training component. Connecting the push rod to the training plate and activating it causes the push rod to reciprocate, causing the training plate to swing along with it, thus causing the patient's legs to swing, achieving a passive training effect. Disconnecting the output end of the push rod from the training plate releases the first elastic element, lifting the training plate. At this point, the patient needs to actively use their legs to overcome the elastic force of the first elastic element and press the training plate down, repeating this process continuously to achieve an active training effect.

[0016] The lower limb training and rehabilitation device of this application can not only passively train the patient's lower limbs and achieve the initial exercise and recovery effect, but also enable the patient to actively exert force to train after the patient has recovered to a suitable stage, thereby improving the rehabilitation effect of the lower limb training and rehabilitation device in actual use and improving the practicality of this application.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This embodiment provides a lower limb training and rehabilitation device to solve the problem in related technologies where rehabilitation devices can only perform passive training, resulting in poor training effects.

[0032] Please see Figures 1 to 3This embodiment provides a lower limb training and rehabilitation device, including a seat 100 and a training component 200. The seat 100 has a seat surface 110. The training component 200 includes a training plate, which is hinged to the edge of the seat surface 110. A passive training section 300 and an active training section 400 are disposed on the seat 100 facing the training plate. The passive training section 300 includes a pusher 310, the output end of which is detachably abutted against the end of the training plate away from the seat surface 110, for pushing the training plate to swing. The active training section 400 includes a first elastic member 420, which is disposed between the training plate and the seat 100. When the output end of the pusher 310 is connected to the training plate, the first elastic member 420 is in a compressed state.

[0033] Specifically, when using the lower limb training and rehabilitation device of this embodiment, the patient sits on the seat surface 110 of the seat body 100 and lets his lower limbs hang down naturally, so that his lower limbs are in contact with the training board of the training component 200.

[0034] When the patient's lower limbs have not recovered well and are not suitable for active training, the output end of the pusher 310 is installed on the training board. Then, the pusher 310 is activated, and the pusher 310 can control the repeated extension and retraction of the output end, that is, push the training board to swing, thereby causing the patient's lower limbs to swing while they are attached to the training board. The patient does not need to exert any force, so that the patient's lower limbs can be passively trained.

[0035] After the patient's lower limbs have recovered for a period of time, or have recovered well enough to exert force on their own, the output end of the pusher 310 is removed from the training board. At this point, the first elastic element 420 is no longer restricted and releases, lifting the training board. The patient can then control the exertion of their lower limbs to overcome the elasticity of the first elastic element 420 and press the training board down again. After pressing down, the patient stops exerting force, and the training board will be lifted up again by the action of the first elastic element 420. This process is repeated, enabling the patient's lower limbs to perform active training and improving the rehabilitation effect.

[0036] In this embodiment, the number of the first elastic element 420 can be set according to the actual recovery of the patient's lower limbs, so that the elastic force of the first elastic element 420 matches the force required for the patient's lower limb exercise, thereby ensuring that this embodiment has a good exercise effect.

[0037] In one embodiment, exemplarily, such as Figure 1 , Figure 5As shown, the training board includes a first plate body 210 and a second plate body 220 for fixing and supporting the patient's lower limbs. The first plate body 210 is hinged to the seat surface 110. A cavity is formed on the first plate body 210 extending from the end away from the seat surface 110 towards the end closer to the seat surface 110. The second plate body 220 is slidably installed within the cavity and can be relatively fixed to the first plate body 210. Different patients have different leg lengths and rehabilitation needs. By adjusting the position of the second plate body 220 within the cavity of the first plate body 210, the overall length of the training board can be flexibly changed to adapt to various leg lengths or rehabilitation stages. The length of the training board can be adjusted according to individual needs, allowing the device to better fit the patient's lower limbs and provide a more comfortable support and training experience.

[0038] Adjusting the length of the training board precisely according to the patient's specific rehabilitation condition helps optimize training posture and force distribution, ensuring optimal results with each training session. For example, during active training, appropriate length adjustments can help patients apply force more accurately, avoiding additional injuries caused by improper posture.

[0039] In one embodiment, exemplarily, such as Figure 5 As shown, a straight groove communicating with the outside is formed on the first plate 210 along the sliding direction of the second plate 220. A bolt fastener 222 is provided on the second plate 220, threadedly connected to it and passing through the straight groove. Thus, when the relative position of the first plate 210 and the second plate 220 needs to be adjusted, the bolt fastener 222 is loosened, allowing the first plate 210 and the second plate 220 to move relative to each other. After moving to the appropriate position, the bolt fastener 222 is tightened again, pressing against the surface of the first plate 210, thus fixing the first plate 210 and the second plate 220 relative to each other. Of course, any other fixing method can be used between the first plate 210 and the second plate 220, as long as it meets the adjustment requirements of this embodiment.

[0040] In one embodiment, exemplarily, such as Figure 1 , Figure 5 As shown, a third plate 230 is hinged to the end of the second plate 220 away from the first plate 210 to fix and support the patient's foot. A telescopic rod 231 is provided between the second plate 220 and the third plate 230, and a second elastic element 232 is provided on the telescopic rod 231 to limit the extension or retraction of the telescopic rod 231. The third plate 230 is used to fix and support the patient's foot and is connected to the second plate 220 by a hinge. In this way, the foot can be adjusted at an angle as needed to better adapt to different rehabilitation postures or training needs, providing more personalized support for the patient.

[0041] The combination of the telescopic bar 231 and the second elastic element 232 can adjust the angle of the foot and the applied force according to the patient's specific rehabilitation condition. Specifically, when the patient's foot also needs rehabilitation or exercise, stepping on the third plate 230 can overcome the restriction of the second elastic element 232 on the telescopic bar 231, causing the third plate 230 to swing relative to the second plate 220. This simulates the foot's movements during actual walking or standing, improving the realism and effectiveness of the rehabilitation training.

[0042] The second elastic element 232 restricts the extension or retraction of the telescopic rod 231. Specifically, when restricting the retraction of the telescopic rod 231, the second elastic element 232 is simply fitted onto the smaller-diameter telescopic body of the telescopic rod 231. When restricting the extension of the telescopic rod 231, the second elastic element 232 is positioned at the bottom of the cylindrical body of the telescopic rod 231, with its two ends connected to the cylindrical body and the telescopic body, respectively. This combination of the telescopic rod 231 and the second elastic element 232 not only allows for precise control of the force applied to the foot but also limits the maximum travel of the telescopic rod 231, preventing excessive stretching or compression during the early stages of rehabilitation or for patients with weak strength control, thus avoiding secondary injuries and improving the safety and practicality of this embodiment.

[0043] In one embodiment, exemplarily, such as Figure 3 , Figure 4 As shown, a first connecting end 320 is provided on the side of the second plate 220 facing the pusher 310; one end of the pusher 310 is hinged to the base 100, and the output end of the pusher 310 is the second connecting end 311, which is detachably mounted on the first connecting end 320. This design allows the pusher 310 to be quickly connected or disconnected from the first connecting end 320 of the second plate 220 as needed. When the patient needs passive training, the second connecting end 311 of the pusher 310 can be easily installed onto the first connecting end 320; while during active training, it can be easily disassembled, thus flexibly switching training modes.

[0044] It should be noted that, in this embodiment, the structures of the first connecting end 320 and the second connecting end 311 can be arbitrarily configured as needed, as long as they meet the requirements of this embodiment, are easy to disassemble and install, and are stable and reliable after installation. For example, the first connecting end 320 is configured as a support for hinged connection, and the second connecting end 311 is configured as a hinge joint, which can be hingedly installed in the support.

[0045] The pusher 310 is configured as an electric actuator, with a hinge connector inserted into the output end of the electric actuator. When the connection is not required, the output end of the electric actuator can be pulled out of the hinge connector.

[0046] In one embodiment, exemplarily, such as Figure 3, Figure 7 As shown, the active training unit 400 includes a support frame 410, which is disposed on the base 100 near the second plate 220. Multiple first elastic members 420 are evenly distributed between the support frame 410 and the second plate 220. Providing the support frame 410 on the base 100 to support the active training unit 400 not only makes the overall structure more stable but also simplifies and facilitates the installation of the active training unit 400 and its related structures.

[0047] Multiple first elastic elements 420 are evenly distributed between the support frame 410 and the second plate 220, ensuring that force is more evenly distributed on the second plate 220 during active training. This helps provide more stable support and avoids discomfort or injury caused by excessive local pressure. The evenly distributed first elastic elements 420 enhance the stability of the overall structure, making the second plate 220 more stable when bearing the force applied by the patient's lower limbs. This reduces potential swaying or instability during training and improves training safety.

[0048] By adjusting the number or intensity of the first elastic element 420, the difficulty of the training can be adjusted according to the patient's rehabilitation progress and individual differences. For example, for patients in the early stages of recovery, softer elastic elements or fewer elements can be selected; while for patients in the later stages of recovery who require a greater challenge, the number of elastic elements can be increased or stronger elements can be selected.

[0049] In one embodiment, exemplarily, such as Figure 3 , Figure 4 , Figure 7 As shown, a connector for connecting the second plate 220 is provided at one end of the first elastic member 420 away from the support frame 410. The connector includes a U-shaped plate 430, which is disposed at the end of the first elastic member 420 and can be snapped onto the second plate 220. During use, the U-shaped plate 430 can be directly snapped onto the second plate 220, ensuring the connection strength between the first elastic member 420 and the second plate 220, and ensuring that there will be no loosening or detachment during training, thereby improving the safety and reliability of the entire device.

[0050] In one embodiment, exemplarily, such as Figure 3 , Figure 4 , Figure 7As shown, a through groove 221 is formed at the end of the second plate 220 away from the first plate 210, and a connecting groove 431 is formed on the U-shaped plate 430, which can communicate with the through groove 221. The connector also includes a plug 440, which passes through the connecting groove 431 and is inserted into the through groove 221. The plug 440 passes through the connecting groove 431 on the U-shaped plate 430 and is inserted into the through groove 221 of the second plate 220. This physical locking enhances the connection stability between the first elastic member 420 and the second plate 220, ensuring that no accidental loosening or detachment will occur during active training, especially under the application of large pressure or tension.

[0051] The use of the insertion rod 440 for fixation makes installation and disassembly more intuitive and simple. Operation is completed simply by inserting or removing the insertion rod 440, without the need for complicated tools or procedures, greatly facilitating the process for patients or medical staff to adjust the device configuration as needed. Furthermore, the presence of the insertion rod 440 adds an extra layer of safety, preventing potential risks caused by accidental slippage of the U-shaped plate 430, providing double protection for the entire connection system and further enhancing the safety of use.

[0052] It should be noted that the cross-sections of both the insertion rod 440 and the through groove 221 are set to rectangles, thereby ensuring that the insertion rod 440 and the through groove 221 will not rotate relative to each other, and ensuring that the connection between the insertion rod 440 and the through groove 221 is reliable.

[0053] In one embodiment, exemplarily, such as Figure 3 , Figure 4 As shown, a fixing groove 441 is formed at the end of the insertion rod 440 extending into the through groove 221. A limiting rod 451 is inserted into the fixing groove 441, and a pull ring 452 is provided on the limiting rod 451 outside the fixing groove 441. The limiting rod 451 is inserted into the fixing groove 441 of the insertion rod 440, further locking the position of the insertion rod 440 and preventing it from accidentally slipping out or loosening. The additional locking mechanism greatly enhances the safety and stability of the entire connection system. In particular, both the insertion rod 440 and the through groove 221 are designed to be non-rotatable relative to each other, ensuring that the limiting rod 451 will not come out during use, and ensuring the safety of this embodiment even during high-intensity training.

[0054] The pull ring 452 makes inserting and removing the limiting rod 451 much easier. Patients or healthcare professionals can quickly insert or pull out the limiting rod 451 into the fixing slot 441 using the pull ring 452 without the need for additional tools, greatly simplifying the installation and disassembly process and improving operational efficiency.

[0055] In one embodiment, exemplarily, such as Figure 3 , Figure 7As shown, a storage compartment 411 is provided on the side of the support frame 410 away from the training board. The storage compartment 411 can be used to store various accessories of the rehabilitation training device, such as first elastic elements 420 of different strengths, limit rods 451, insertion rods 440, etc., as well as necessary tools, such as small tools for adjusting the device. This allows all relevant items to be stored in one place, making them convenient to use at any time and avoiding the waste of time searching for the required items.

[0056] Of course, other items needed by patients or medical staff can also be placed in the storage compartment 411, thereby improving the practicality of this embodiment.

[0057] In one embodiment, exemplarily, such as Figure 1 , Figure 5 As shown, the first plate 210, the second plate 220, and the third plate 230 are all equipped with restraints 240 for securing the patient's lower limbs or feet to the training board. The restraints 240 ensure that the patient's lower limbs or feet are securely fixed to the training board during rehabilitation training. This improves the fit between the patient and the training board, reducing the risk of injury due to limb slippage or accidental movement, which is especially important during active training of a certain intensity.

[0058] When a patient's lower limbs or feet are securely immobilized, it allows for more effective training targeting specific muscle groups. Fixed support points help concentrate force on the target area, thereby improving training effectiveness and promoting a faster recovery process.

[0059] In one embodiment, exemplarily, such as Figure 3 , Figure 6 As shown, the active training unit 400 also includes a hinge rod 460, which is hingedly mounted on the base 100 near the first plate 210. An L-shaped plate 461 is provided at the end of the hinge rod 460 away from the base 100. The L-shaped plate 461 is attached to the first plate 210, and a third elastic member 462 is provided between the hinge rod 460 and the L-shaped plate 461.

[0060] Specifically, when using this embodiment for active training, the first elastic element 420 will push the second plate 220 and the first plate 210 away from the seat 100. When the patient presses the first plate 210 and the second plate 220 down, he / she needs to exert force to achieve the training effect.

[0061] In this embodiment, the L-shaped plate 461 is attached to the first plate 210, and the L-shaped plate 461 is disposed on the side of the first plate 210 away from the first elastic member 420. Thus, when the first elastic member 420 lifts the first plate 210, the L-shaped plate 461 naturally adheres to the first plate 210 and slides relative to it. Furthermore, when the patient actively exerts force with their lower limbs to lift the first plate 210 through the restraint member 240, the hinge rod 460 is hinged to the seat 100. During the lifting process, the third elastic member 462 is compressed. In other words, although the first elastic member 420 assists in exerting force when the patient lifts the first plate 210, the patient also needs to exert some force themselves to overcome the third elastic member 462.

[0062] In summary, when the patient's lower limbs are bound to the first plate 210 and the second plate 220, swinging towards the first elastic element 420 requires force to compress the first elastic element 420, and swinging away from the first elastic element 420 requires force to compress the third elastic element 462. This allows the patient's lower limbs to receive more comprehensive exercise, improving the practicality of this embodiment.

[0063] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
