Description

Technical Field

[0001] This invention relates to non-surgical treatment of joints, and more specifically to the field of medical device technology, specifically a leg rehabilitation and care device. Background Technology

[0002] Leg rehabilitation is a core component of postoperative recovery, sports injury repair, intervention for sarcopenia in the elderly, and functional maintenance for patients with chronic diseases. Through standardized stretching and bending repetitive movements, it gradually restores joint mobility, enhances muscle tone, and prevents muscle atrophy and joint stiffness. Targeted massage care promotes local blood circulation, relieves muscle soreness after training, accelerates the excretion of metabolic waste, and provides a good environment for tissue repair. From the perspective of user groups, postoperative patients need to perform low-intensity, precise rehabilitation movements under the guidance of doctors, the elderly need easy-to-operate and safe assistive devices, and sports enthusiasts focus on the synergistic effect of training and relaxation.

[0003] The traditional techniques and corresponding equipment currently used for leg rehabilitation are mainly designed based on single functional needs. One type is leg stretching and bending reciprocating training techniques, the core principle of which is to guide the leg to complete preset movements through mechanical structures. Based on the power source, it can be further divided into passive and active types. The other type is leg massage and blood circulation techniques, the principle of which mainly revolves around physical stimulation to promote circulation, including mechanical kneading, air pressure squeezing and heat-assisted methods.

[0004] Although traditional techniques have been widely used in single rehabilitation scenarios, training equipment and massage devices are independent of each other. Users need to switch devices for massage after completing stretching and bending exercises, which is cumbersome and space-consuming. The range of motion and frequency of traditional training equipment are mostly fixed levels, which cannot be dynamically adjusted according to the user's leg size and rehabilitation stage, lacking personalized adaptation capabilities. The area of ​​action and intensity of massage devices cannot match the muscle exertion points of the training movements, and cannot provide simultaneous light massage and relaxation, which can easily lead to the accumulation of muscle tension and increase the risk of sports injuries. Therefore, a leg rehabilitation care device is proposed to solve the above-mentioned problems. Summary of the Invention

Detailed Implementation

[0022] 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.

[0023] Example 1 Please see Figures 1-9 The present invention provides a leg rehabilitation and care device, including an electric push rod 1, model LINAKLA27 medical-grade, a massage part 2 on the electric push rod 1, an adapter part 3 on the massage part 2, a monitoring part 4 on the massage part 2 and the adapter part 3, a support part 5 on the electric push rod 1, and a binding part 6 on the support part 5.

[0024] In this invention, the massage unit 2 uses gear meshing and rod linkage to synchronously knead and massage the legs by controlling the linear motion of the electric push rod 1, thus integrating rehabilitation training and massage movements. It includes a connecting arm 21, which is fixedly sleeved on the outer rod of the electric push rod 1. A frame 22 is fixedly connected to the connecting arm 21. A hollow gear 23 and a gear 24 are rotatably connected to the inner wall of the frame 22. The hollow gear 23 and the gear 24 mesh with each other. A limiting frame 25 is fixedly connected to one side of the frame 22. A toothed arm 26 is slidably connected to the inner wall of the limiting frame 25. The toothed arm 26 meshes with the hollow gear 23. A connecting arm 27 is fixedly connected to the end of the toothed arm 26. The connecting arm 27 is also fixedly sleeved on the inner rod of the electric push rod 1.

[0025] In this embodiment, a support arm 28 is fixedly connected to one side of the hollow gear 23, and a support arm 29 is fixedly connected to the support arm 28. A roller frame 210 is provided on the support arm 29, and a massage roller 211 is rotatably connected to the roller frame 210. The fitting part 3 adapts to the leg size of different users, always maintaining a close fit and uniform pressure, avoiding pressure or poor fit, and improving fit and comfort. It includes a slide groove 31, which is formed on the support arm 29. A slider 32 that slides and adapts to the slide groove 31 is fixedly connected to the roller frame 210. The end of the roller frame 210 is provided with a sliding hole. A sliding rod 33 that is adapted to slide through the sliding hole is fixedly connected to the roller frame 210. A spring 34 is elastically connected between the roller frame 210 and the end of the second support arm 29. A threading ring 35 is fixedly connected to the side of the roller frame 210. The first support arm 28, the second support arm 29, the roller frame 210, the massage roller 211 and the adapter 3 together form a single-sided massage mechanism. There are two single-sided massage mechanisms. The two single-sided massage mechanisms are symmetrically arranged with each other. The first support arm 28 in the other single-sided massage mechanism is fixedly connected to one side of the gear 24.

[0026] It is worth noting that the monitoring unit 4 collects data through sensors, processes it through a microprocessor, and then controls the actions of various components to ensure the safety and accuracy of rehabilitation. It includes a support 41, on which a housing 42 is mounted. A distance sensor 43, model HokuyoURG04LX-UG01 laser infrared composite, is mounted on the top of the support 41. The monitoring unit 4 also includes electrode patches 44 and heating patches 45. A monitoring plate 46 adapted to the distance sensor 43 is mounted on the roller frame 210 in one of the single-sided massage mechanisms. The housing 42 contains a microprocessor and a power system. The distance sensor 43 is electrically connected to the microprocessor. The wiring of the electrode patches 44 and the heating patches 45 is electrically connected to the microprocessor through a wire loop 35. The power system provides power support for the electric push rod 1, the distance sensor 43, the electrode patches 44, and the heating patches 45. The microprocessor, as the control core, realizes the coordinated linkage of various components.

[0027] It is worth noting that the support part 5 is adapted to the joint movement trajectory when the leg is stretched or bent, providing stable support for the leg. It includes a U-shaped frame 51, a hinge plate 52 fixedly connected to the U-shaped frame 51, a rotating head 53 hinged to the hinge plate 52, a limiting groove 54 opened on the inner wall of the ear end of the U-shaped frame 51, a groove 55 opened on the ear end of the U-shaped frame 51, a torsion spring is provided on the inner wall of the groove 55 and a clamping arm 56 is elastically connected to it through the torsion spring, and the clamping arm 56 is elastically fixed by the torsion spring, which enhances the overall stability of the device and prevents displacement during movement.

[0028] Furthermore, the binding part 6 enables quick leg fixation, avoids compression of leg blood vessels, and improves ease of use and safety. It includes a limit rod 61, a limit hole on the U-shaped frame 51, one end of the limit rod 61 slides through the limit hole and is fixedly connected to a leg support 62, the other end of the limit rod 61 is fixedly connected to a limit plate 63, a spring 64 is elastically connected between the leg support 62 and the inner wall of the U-shaped frame 51, a limit block 65 that slides and adapts to the limit groove 54 is fixedly connected to the outer wall of the leg support 62, a strap 66 is fixedly connected to the inner wall of the leg support 62, and the end of the strap 66 is provided with Velcro. There are two support parts 5 and two binding parts 6. The other binding part 6 is installed on the other support part 5. The opposing rotating heads 53 in the two support parts 5 are fixedly connected to the outer rod end and the inner rod end of the electric push rod 1, respectively.

[0029] In use, the device uses the electric push rod 1 as the core power source. The extension and retraction of its outer and inner rods provides the basic driving force for all functional actions. When the electric push rod 1 extends and retracts, the relative displacement of the outer and inner rods will drive the connecting arm 1 21 and connecting arm 27 to produce synchronous and opposite movements. Connecting arm 1 21 and connecting arm 27 are respectively connected to the transmission structure of the massage part 2 and the steering structure of the support part 5, realizing the synchronous linkage of rehabilitation actions and massage actions without the need for an additional independent power source.

[0030] The massage unit 2 is linked with the linkage through gear meshing to convert the linear motion of the electric push rod 1 into the oscillating and kneading action of the massage roller 211. When the inner rod of the electric push rod 1 extends or retracts, it drives the toothed arm 26 to slide along the limiting frame 25, driving the empty sleeve gear 23 to rotate. At the same time, it drives the gear 1 24 to rotate synchronously in the opposite direction. The opposite rotation of the empty sleeve gear 23 and the gear 1 24 drives the two single-sided massage mechanisms to oscillate, that is, the support arm 1 28 drives the support arm 2 29 to oscillate relative to each other. When the electric push rod 1 extends or retracts, the massage roller 211 adheres to the leg and performs a kneading action.

[0031] The adapter 3, through its elastic structure and sliding fit, ensures that the massage roller 211 fits different leg sizes, avoiding pressure or poor fit. The roller frame 210 is slidably fitted with the slide groove 31 of the support arm 29 via the slider 32, and simultaneously slidably fitted with the slide hole of the support arm 29 via the slide rod 33, restricting the roller frame 210 to move only in the direction of the leg. The spring 34 between the roller frame 210 and the end of the support arm 29 provides elastic preload, keeping the massage roller 211 in place and always providing uniform massage pressure. The wire loop 35 on the roller frame 210 is used to organize the wiring of the electrode patch 44 and the heating patch 45, preventing the wiring from getting tangled or pulled during movement.

[0032] The monitoring unit 4, through the distance sensor 43 and the monitoring plate 46 on one of the roller frames 210, monitors the oscillation frequency of the massage roller 211 in real time. When the electric push rod 1 completes one extension and retraction movement, the infrared signal of the monitoring plate 46 and the distance sensor 43 responds once. The rehabilitation course can be preset, thereby achieving the rehabilitation effect of small amounts and multiple times, avoiding muscle fatigue caused by long-term rehabilitation training.

[0033] Electrode patches 44 are attached to the target muscle group of the leg to collect electromyographic signals to reflect the muscle activation state. The microprocessor analyzes the signals to determine the degree of muscle tension and dynamically adjusts the heating temperature of the heating patch 45 to achieve dynamic monitoring of muscle status and blood circulation.

[0034] The support part 5 and the binding part 6 work together to achieve stable fixation of the leg and adapt to the angle of rehabilitation movements. The U-shaped frame 51 of the support part 5 is connected to the rotating head 53 through the hinge plate 52. When the electric push rod 1 drives the leg to stretch or bend, the rotating head 53 can rotate around the hinge plate 52 to adapt to the natural movement trajectory of the knee joint. The leg support 62 of the binding part 6 slides with the limiting hole of the U-shaped frame 51 through the limiting rod 61. The spring 64 between the leg support 62 and the U-shaped frame 51 provides elastic cushioning to avoid compressing blood vessels in the leg during fixation. The limiting block 65 works with the limiting groove 54 of the U-shaped frame 51 to restrict the leg support 62 to move only in a fixed direction to ensure stability.

[0035] Example 2 Please see Figures 1-10 In this embodiment, a leg sleeve 7 is provided between the two binding parts 6, and the two ends of the leg sleeve 7 are respectively provided on the straps 66 of the two binding parts 6.

[0036] When in use, the leg sleeves 7 can be replaced according to the needs of use. The straps 66 can be quickly fixed to the legs with Velcro. Together with the leg sleeves 7, they wrap around the legs, enhancing the comfort of the fixation and making the massage rollers 211 and heating pads 45 work more evenly.
