Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a rehabilitation massager. Background Art

[0002] Rheumatoid arthritis is one of the common diseases that can affect both men and women. It not only affects people's normal life, but also leads to loss of mobility, so it is receiving more and more attention. Rehabilitation training for patients with rheumatoid arthritis requires long-term persistence, but rehabilitation care for rheumatoid arthritis cannot take targeted and effective rehabilitation exercises during the nursing process.

[0003] When patients perform leg bending exercises on their own, they cannot control the angle of each bending exercise. If the angle is too large, it will cause pain in the leg joints. If the angle is too small, the exercise effect will be unsatisfactory. At the same time, if the patient's exercise time is too long, they will gradually experience soreness and weakness due to frequent leg lifting. If the exercise time is too short, the rehabilitation efficiency will be low. Therefore, the present invention designs a rehabilitation massager to solve the above problems. Summary of the invention

[0016] 2. After the bending angle of the calf support plate is determined, the reciprocating pushing effect of the electromagnet inside the pushing component on the magnetic block and the limiting effect of the blocking rod on the magnetic block can replace manual control of the swing frequency and amplitude of the calf support plate, making the swing amplitude more precise and avoiding manual frequent rotation of the wheel to control the bending angle of the leg, which in turn causes soreness and weakness in the arm.

[0017] 3. This device can control the up and down movement of the lifting plate by the patient turning the control wheel and rotating the control rod, thereby controlling the contact force between the first sponge block and the patient's legs. That is, the patient can control the pressing force of the sponge block on the leg according to the thickness of his or her own legs, so as to avoid discomfort in the patient's legs due to excessive pressing force, and to avoid the situation where the pressing force is too small, causing the patient's legs to move during exercise, thereby affecting the exercise effect.

[0018] 4. This device presses the patient's legs alternately through the first sponge block and the second sponge block inside the breathable component, which can avoid one sponge block pressing the patient's legs for a long time, making the pressed area unable to contact with the outside air, resulting in the patient's legs being pressed for a long time, and may cause stuffiness, sweating, and blood circulation due to the lack of air circulation.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0022] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a rehabilitation massager, comprising a telescopic column 1, the top of the telescopic column 1 is fixedly connected to a supporting mechanism 2, and the outer surface of the supporting mechanism 2 is rotatably connected to a clamping mechanism 3; the telescopic column 1 provides support for the supporting mechanism 2 and has a telescopic function, which can be telescoped and adjusted according to the distance between the bottom of the human thigh and the ground, and the clamping mechanism 3 is used to fix the outer surface of the human thigh and calf.

[0023] First, when the patient needs to use this device to exercise and care for the leg joints, the thighs and calves are placed on the upper surface of the support mechanism 2, and the height of the support mechanism 2 and the ground is adjusted by the telescopic rod 2744 to facilitate supporting the patient's thigh area, and the patient's legs are compressed by the compression mechanism 3.

[0024] The support mechanism 2 includes a thigh support plate 21, the inner wall of which is fixedly connected with a magnetic plate 22, the outer surface of which is fixedly connected with a connecting block 23, the inner wall of which is rotatably connected with a rotating shaft 24, the outer surface of which is fixedly connected with a connecting plate 25, the side of which away from the rotating shaft 24 is fixedly connected with a calf support plate 26, the bottom of which is fixedly connected with an exercise component 27; the thigh support plate 21 is used to support the lower surface of the thigh, and the calf support plate 26 can rotate around the outer surface of the connecting block 23 together with the connecting plate 25 and the rotating shaft 24, thereby adjusting the angle between the calf support plate 26 and the thigh support plate 21; wherein, the inner surfaces of the thigh support plate 21 and the calf support plate 26 are both fixedly connected with magnetic plates 22.

[0025] The exercise component 27 includes a rotating wheel 271, a screw rod 272 is fixedly connected to the side of the rotating wheel 271 close to the calf support plate 26, a pushing component 273 is rotatably connected to the outer surface of the screw rod 272, a moving component 274 is threadedly connected to the outer surface of the screw rod 272, a pull rope 275 is fixedly connected to the side of the moving component 274 away from the rotating wheel 271, a limit block 276 is sleeved on the outer surface of the pull rope 275, a spring sheet 277 is fixedly connected to the side of the limit block 276 close to the moving component 274, and a support frame 278 is fixedly connected to the end of the spring sheet 277 away from the limit block 276. The moving component 274 can be moved by pulling the pull rope 275, so that the calf support plate 26 rotates around the outer surface of the connecting block 23. The limiting block 276 limits the outer surface of the pull rope 275, and the spring sheet 277 has elasticity and reset effects. In the initial position, the spring sheet 277 has a strong supporting effect, which can support the bottom of the calf support plate 26 and make the calf support plate 26 in a horizontal state.

[0026] The bottom of the thigh support plate 21 is fixedly connected to the top of the telescopic column 1, the top of the pushing component 273 is fixedly connected to the lower surface of the thigh support plate 21, the end of the pull rope 275 away from the moving component 274 is fixedly connected to the bottom of the calf support plate 26, and the top of the support frame 278 is fixedly connected to the bottom of the thigh support plate 21.

[0027] When the patient places his thigh on the thigh support board 21 and his calf on the calf support board 26, the patient's leg bones are stiff and in a straight line, and the patient's legs need to be bent. After the upper part of the patient's leg is fixed by the clamping mechanism 3, the patient manually rotates the wheel 271, and the wheel 271 drives the screw rod 272 to rotate, thereby driving the moving part 274 to move along the outer surface of the screw rod 272, so that the moving part 274 moves away from the support frame 278. In the process of the moving part 274 moving away from the support frame 278, the pull rope 275 is pulled to move toward the side close to the pushing part 273, and the pull rope 275 is pulled to pull the calf support board 26, the connecting plate 25, and the connecting plate 26. The shaft rotates downward around the outer surface of the connecting block 23, and the top of the spring sheet 277 is squeezed during the rotation of the calf support plate 26. When the patient feels that the bending angle of the calf support plate 26 is just right, the rotation of the rotating wheel 271 is no longer controlled. Therefore, the patient can adjust the moving distance of the moving component 274 according to his or her own needs. When the moving distance is determined, the downward rotation angle of the calf support plate 26 is also determined. By determining the downward rotation angle of the calf support plate 26, the amplitude of the patient's calf bending exercise can be controlled, thereby enhancing the therapeutic effect on the patient's arthritis.

[0028] The pushing component 273 includes a fixed block 2731, a sleeve block 2732 is fixedly connected to the bottom of the fixed block 2731, a slide rail 2733 is fixedly connected to the inner wall of the sleeve block 2732, a slide table 2734 is slidably connected to the outer surface of the slide rail 2733, a split frame 2735 is fixedly connected to the upper surface of the slide table 2734, and an electromagnet 2736 is fixedly connected to the side of the split frame 2735 close to the support frame 278. The slide rail 2733 can control the slide table 2734 to slide along its surface, and at the same time control the sliding of the split frame 2735 and the electromagnet 2736, so that the electromagnet 2736 is closer and closer to the moving component 274. Among them, the sleeve blocks 2732 are symmetrically arranged on both sides of the slide rail 2733, and the sleeve block 2732 on the side away from the fixed block 2731 is fixedly connected to the bottom of the support frame 278.

[0029] The top of the fixing block 2731 is fixedly connected to the lower surface of the thigh supporting plate 21 , and the sleeve block 2732 is arranged on both sides of the slide rail 2733 .

[0030] The moving component 274 includes a moving block 2741, the inner wall of which is provided with a sliding groove 2742, a side of the moving block 2741 close to the fixed block 2731 is provided with a square groove 2743, the inner wall of the moving block 2741 is fixedly connected with a telescopic rod 2744, the top of the telescopic rod 2744 is fixedly connected with a bent frame 2745, the inner wall of the bent frame 2745 is fixedly connected with a blocking rod 2746, a magnetic block 2747 is arranged below the bent frame 2745, the side of the magnetic block 2747 away from the blocking rod 2746 is movably connected with an extrusion spring 2748, and the end of the extrusion spring 2748 away from the blocking rod 2746 is fixedly connected with a pressure sensor 2749. The telescopic rod 2744 can control whether the magnetic block 2747 can slide along the inner wall of the movable block 2741 by controlling the up and down movement of the bending frame 2745 and the blocking rod 2746. The pressure sensor 2749 and the extrusion spring 2748 cooperate to detect the extrusion force of the magnetic block 2747 on both. The opening of the slide groove 2742 facilitates the sliding of the split frame 2735.

[0031] The inner wall of the moving block 2741 is threadedly connected to the outer surface of the screw rod 272, the outer surface of the blocking rod 2746 is slidably connected to the inner wall of the moving block 2741, the outer surface of the magnetic block 2747 is slidably connected to the inner wall of the moving block 2741, and the side of the pressure sensor 2749 away from the extrusion spring 2748 is fixedly connected to the inner wall of the moving block 2741.

[0032] After the patient has adjusted the angle at which the calf support plate 26 rotates downward, the slide rail 2733 starts and drives the slide table 2734 to move along its surface, so that the slide table 2734 drives the split frame 2735 and the electromagnet 2736 to move toward the side close to the support frame 278. The electromagnet 2736 is in an energized state. Therefore, when the electromagnet 2736 gets closer and closer to the magnetic block 2747, the magnetic block 2747 will slide along the inner surface of the moving block 2741 toward the side close to the extrusion spring 2748 and the pressure sensor 2749. When the force sensor 2749 senses a greater pressure, it controls the telescopic rod 2744 to drive the bending frame 2745 to move upward. When the bending frame 2745 moves upward a certain distance, it will drive the blocking rod 2746 to slide upward along the inner surface of the moving block 2741. Since the electromagnet 2736 has a strong adsorption force on the magnetic block 2747, when the blocking rod 2746 loses contact with the outer surface of the moving block 2741, the moving block 2741 has been adsorbed by the magnetic block 2747 and will not move along the inner surface of the moving block 2741 toward the side close to the pull rope 275.

[0033] When the electromagnet 2736 is attracted to the magnetic block 2747, the slide 2734 will control the split frame 2735 and the electromagnet 2736 to continue to slide toward the side close to the pull rope 275. The split frame 2735 can slide along the inside of the slide groove 2742, and the electromagnet 2736 can pass through the square groove 2743 during movement. Therefore, the movement of the split frame 2735 and the electromagnet 2736 will not be affected by the position of the moving block 2741. As the electromagnet 2736 pushes the magnetic block 2747 out of the moving block 2741, the pulling force of the magnetic block 2747 on the pull rope 275 gradually decreases. Therefore, the calf support plate 26 will tighten the pull rope 275 under the elastic support of the spring sheet 277, and drive the connecting plate 25 and the rotating shaft 24 to reset and rotate upward along the outer surface of the connecting block 23 until the calf support plate 26 returns to the horizontal position again.

[0034] When the calf support plate 26 returns to the horizontal position, the slide 2734 resets and moves, and the electromagnet 2736 drives the magnetic block 2747 to reset again. When the magnetic block 2747 is reset, it pulls the calf support plate 26 to rotate downward again through the pull rope 275. When the magnetic block 2747 is reset, the blocking rod 2746 is still above the moving block 2741 and will not hinder the reset movement of the magnetic block 2747. When the magnetic block 2747 is reset to a certain distance and contacts the inner surface of the moving block 2741 again, the moving block 27 The inner surface of the slider 2734 will limit the magnet 2747, and the electromagnet 2736 will eventually break contact with the outer surface of the magnet 2747. At this time, the magnet 2747 will squeeze the extrusion spring 2748 to a certain extent. When the pressure sensor 2749 senses a certain pressure value again, the telescopic rod 2744 will be controlled to retract and reset, driving the bending frame 2745 and the blocking rod 2746 to reset downward. The blocking rod 2746 will limit the side of the magnet 2747 away from the extrusion spring 2748, and prevent the magnet 2747 from sliding toward the side close to the pull rope 275. Therefore, the reciprocating motion of the slide 2734 can replace the manual control of the swing frequency and swing amplitude of the calf support plate 26.

[0035] For example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the clamping mechanism 3 includes a circular shaft 31, the outer surface of the circular shaft 31 is fixedly connected to a cover plate 32, the side of the cover plate 32 away from the circular shaft 31 is fixedly connected to an adsorption block 33, the top of the cover plate 32 is rotatably connected to a regulating component 34, and both ends of the circular shaft 31 are rotatably connected to the inner surface of the calf support plate 26. The cover plate 32 can drive the adsorption block 33 to rotate around the outer surface of the circular shaft 31, and the upper space of the calf support plate 26 and the thigh support plate 21 is opened or closed by the rotation of the cover plate 32. The adsorption block 33 is a magnetic material and is mutually adsorbed with the magnetic plate 22.

[0036] The regulating component 34 includes a regulating wheel 341, a regulating rod 342 is fixedly connected to the bottom of the regulating wheel 341, a lifting plate 343 is threadedly connected to the outer surface of the regulating rod 342, a pressing sheet 344 is fixedly connected to the bottom of the lifting plate 343, a first interlayer 345 is fixedly connected to the bottom of the pressing sheet 344, a first sponge block 346 is fixedly connected to the inner wall of the first interlayer 345, a laser 347 is fixedly connected to the outer surface of the first interlayer 345, and a breathable component 348 is fixedly connected to the upper surface of the lifting plate 343. The regulating rod 342 has the same function as the screw rod 272, and can control the up and down movement of the lifting plate 343, the first interlayer 345, and the first sponge block 346, and compress the patient's legs through the sponge block. The pressing sheet 344 is made of elastic material and has elasticity and reset effects.

[0037] By rotating the cover plate 32 and the circular shaft 31, the upper part of the calf support plate 26 is covered to achieve contact between the adsorption block 33 and the magnetic plate 22. At this time, the patient manually rotates the control wheel 341 to further control the rotation of the control rod 342. During the rotation, the control rod 342 drives the lifting plate 343 and the extrusion plate 344, the first interlayer 345, and the first sponge block 346 to move downward until the first sponge block 346 contacts the patient's leg. By manually controlling the rotation of the control wheel 341, the patient can control the pressing force of the sponge block on the leg according to the thickness of the patient's own leg, so as to avoid discomfort in the patient's leg due to excessive pressing force, and to avoid the situation where the patient's leg moves during exercise and care due to insufficient pressing force.

[0038] The air permeable component 348 includes a sliding rope 3481, the outer surface of which is slidably connected to a limiting tube 3482, the end of the sliding rope 3481 away from the first interlayer 345 is fixedly connected to the second interlayer 3483, the inner surface of the second interlayer 3483 is fixedly connected to a second sponge block 3484, the top of the second interlayer 3483 is fixedly connected to an electric rod 3485, the side of the second interlayer 3483 close to the first interlayer 345 is fixedly connected to a receiver 3486, the end of the sliding rope 3481 away from the second interlayer 3483 is fixedly connected to the upper surface of the first interlayer 345, the bottom end of the limiting tube 3482 is fixedly connected to the upper surface of the lifting plate 343, and the top of the electric rod 3485 is fixedly connected to the bottom of the lifting plate 343. The second sponge block 3484 can fix the patient's legs, and the limiting tube 3482 limits the movement of the sliding rope 3481.

[0039] When the first sponge blocks 346 on both sides of the regulating rod 342 are pressed against the patient's legs, the second sponge block 3484 is higher than the first sponge block 346. When the first sponge block 346 presses the upper surface of the leg for a certain period of time, the electric rod 3485 starts and extends, driving the second interlayer 3483, the second sponge block 3484 and the receiver to move downward. In the process of the second interlayer 3483 moving downward, the first interlayer 345 and the first sponge block 346 are driven upward by the sliding rope 3481, so that the first sponge block 346 is out of contact with the patient's legs. At the same time, the second interlayer 3483 is moved upward to move the first sponge block 346 upward. When the first interlayer 345 moves upward, the laser 347 will be moved upward as well. Therefore, when the laser 347 and the receiver 3486 are at the same horizontal position, the signal emitted by the laser 347 is received by the receiver 3486, and the electric rod 3485 controls the second interlayer 3483 to move downward by twice the distance that the receiver 3486 has moved. After that, when the second sponge block 3484 contacts the upper surface of the patient's leg, the electric rod 3485 stops extending and presses the patient's leg through the second sponge block 3484.

[0040] When the second sponge block 3484 presses the patient's leg for a certain period of time, the electric rod 3485 is reset, driving the second interlayer 3483 to reset, and the first interlayer 345 moves downward so that the first sponge block 346 is pressed against the patient's leg, thereby realizing the alternating pressing of the first sponge block 346 and the second sponge block 3484. By alternately pressing the two sponge blocks, it is avoided that one sponge block presses the patient's leg for a long time, resulting in the inability of the pressed area to contact with the outside air. After long-term pressing, the air may not circulate, the patient may feel stuffy, sweaty, etc. By alternately pressing, the pressed area can alternately contact with the outside air.

[0041] The specific working process of the present invention is as follows: First, when the patient needs to use the device to exercise and care for the leg joints, the thigh and calf are placed on the upper surface of the support mechanism 2, and the height between the support mechanism 2 and the ground is adjusted by the telescopic rod 2744 to facilitate supporting the patient's thigh.

[0042] The movement distance of the moving part 274 is controlled by rotating the screw rod 272 inside the exercise part 27, thereby accurately adjusting the downward rotation angle of the calf support plate 26. When the patient feels that the bending angle of the calf support plate 26 is just right, the rotation of the rotating wheel 271 is no longer controlled.

[0043] After the bending angle of the calf support plate 26 is determined, the reciprocating pushing action of the electromagnet 2736 inside the pushing component 273 on the magnetic block 2747 and the limiting action of the blocking rod 2746 on the magnetic block 2747 can replace manual control of the swing frequency and amplitude of the calf support plate 26. Compared with manual operation, the swing amplitude is more precise, avoiding manual frequent rotation of the wheel to control the bending angle of the leg, which in turn causes soreness and weakness in the arm.

[0044] By driving the rotation of the regulating rod 342 through the regulating wheel 341 inside the clamping mechanism 3, the contact force between the lifting plate 343 and the first sponge block 346 and the patient's legs can be controlled, that is, the pressing force of the sponge block on the legs can be controlled according to the thickness of the patient's own legs, so as to avoid the situation where the pressing force is too large and causes discomfort to the patient's legs, and also avoid the situation where the pressing force is too small and causes the patient's legs to move during exercise.

[0045] Finally, by alternately pressing the patient's legs with the first sponge block 346 and the second sponge block 3484 inside the breathable component 348, it can be avoided that one sponge block presses the patient's legs for a long time, making the pressed area unable to come into contact with the outside air. As a result, after the patient's legs are pressed for a long time, due to the lack of air circulation, they may become stuffy, sweat, and have blood circulation problems, thereby affecting the patient's treatment effect.
