Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an upper limb rehabilitation training device. Background Technology

[0002] In the fields of modern rehabilitation medicine and sports fitness, the demand for upper limb exercises is increasing. Especially for patients whose upper limb function has been impaired due to injury or illness, effective upper limb exercises are crucial for restoring limb function and improving their ability to live independently.

[0003] Currently, there are numerous devices on the market designed for upper limb training. These devices play a significant role in strength training by providing varying levels of resistance to help patients increase upper limb muscle strength. However, these devices generally have a significant limitation: the movement trajectory during exercise is usually relatively fixed, which can easily lead to limb inertia and memory in patients, making it difficult to flexibly demonstrate arm dexterity, quickly and flexibly adjust limb movements, and fully demonstrate arm flexibility. The training methods are also relatively singular, often focusing on strength training while neglecting upper limb flexibility training, which may prevent patients from regaining normal limb function during rehabilitation. Utility Model Content

[0004] This invention provides an upper limb rehabilitation training device that facilitates patients' exercise of upper limb flexibility.

[0005] This utility model provides the following technical solution: It includes a support frame, with a support back plate rotatably connected to the inner side of the support frame. A plurality of fixed indicator lights and a plurality of first positioning sensors are installed on one side of the support back plate, all arranged in a circular array. A rotating carrier ring is rotatably connected to one side of the support back plate, with a plurality of movable indicator lights installed on one side of the rotating carrier ring. A plurality of second positioning sensors are installed on the outer side of the rotating carrier ring, with the movable indicator lights corresponding to the positions of the first positioning sensors. All the movable indicator lights and the plurality of second positioning sensors are arranged in a circular array.

[0006] Among them, a number of hand-operated drive rods are rotatably connected to one side of the rotating carrier ring, and the positions of the number of hand-operated drive rods correspond one-to-one with the positions of the number of activity indicator lights.

[0007] Each of the hand-operated drive rods has a manual switch installed at one end, and the manual switch is electrically connected to the second positioning sensor at the corresponding position.

[0008] The support back plate has an annular groove on one side, and a compression ring is slidably connected to the inner wall of the annular groove. A rubber gasket is installed on one side of the compression ring, and the compression ring contacts the rotating carrier ring through the rubber gasket.

[0009] A U-shaped support rod is installed on one side of the extrusion ring, and a resistance adjustment screw is threadedly connected to the inner wall of the U-shaped support rod. The resistance adjustment screw is rotatably connected to the back of the support back plate.

[0010] The support back plate has a side sliding groove on one side, and a limiting rod is slidably connected to the inner wall of the side sliding groove. The top of the support frame has several insertion holes, and the limiting rod is inserted into the inner wall of the insertion holes.

[0011] The limiting rod has a hand lever installed at one end, which is slidably connected to the inner wall of the side sliding groove. A return spring is installed between the hand lever and the side sliding groove.

[0012] The beneficial effects of this utility model are: by randomly illuminating fixed and movable indicator lights, the patient's hand needs to be moved to different positions of the movable indicator light and rotated by turning the rotating ring. When the fixed and movable indicator lights are aligned, the hand achieves flexibility training. Moreover, the random positions are less likely to cause the patient to develop limb inertia and memory, which is conducive to flexibly demonstrating the flexibility of the arm and fully demonstrating the flexibility of the arm, while also taking into account the training of upper limb strength.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-5 The present invention provides the following technical solution: it includes a support frame 1, a support back plate 2 rotatably connected to the inner side of the support frame 1, a plurality of fixed indicator lights 21 and a plurality of first positioning sensors 22 are installed on one side of the support back plate 2, the plurality of fixed indicator lights 21 and the plurality of first positioning sensors 22 are arranged in a circular array, a rotating carrier ring 3 is rotatably connected to one side of the support back plate 2, a plurality of movable indicator lights 31 are installed on one side of the rotating carrier ring 3, and a plurality of second positioning sensors 32 are installed on the outer side of the rotating carrier ring 3, the movable indicator lights 31 and the first positioning sensors 22 are positioned correspondingly, the plurality of movable indicator lights 31 and the plurality of second positioning sensors 32 are arranged in a circular array.

[0021] In this implementation scheme: the support frame 1 supports all components of the device; the support back plate 2 on top of the support frame 1 can be tilted at an angle, allowing the support back plate 2 to be adjusted to the angle required by the user; the support back plate 2 supports the rotating carrier ring 3; several fixed indicator lights 21 are circumferentially distributed on the outside of the rotating carrier ring 3, with a corresponding number of fixed indicator lights 21 and movable indicator lights 31; when the rotating carrier ring 3 rotates, the movable indicator lights 31 can align with different fixed indicator lights 21; both the fixed indicator lights 21 and the movable indicator lights 31 can illuminate with red and green lights, and the first positioning sensor... Position 22 corresponds to the fixed indicator light 21, and the first positioning sensor 22 is located between the corresponding fixed indicator light 21 and the rotating carrier ring 3. The rotating carrier ring 3 supports and rotates the second positioning sensor 32. When the movable indicator light 31 is angularly aligned with the fixed indicator light 21, the corresponding first positioning sensor 22 and second positioning sensor 32 can approach each other and sense each other. When the patient exercises and uses the device, the PLC control unit inside the support back plate 2 uniformly controls several fixed indicator lights 21 and movable indicator lights 31, so that they can be randomly lit at one time. One fixed indicator light 21 and one movable indicator light 31 display red light. The patient manually rotates the rotating ring 3, which in turn rotates the movable indicator light 31 and the second positioning sensor 32. When the fixed indicator light 21 and the movable indicator light 31 are aligned, the first positioning sensor 22 and the second positioning sensor 32 can achieve alignment sensing, confirming that the fixed indicator light 21 and the movable indicator light 31 are accurately aligned. This causes the fixed indicator light 21 and the movable indicator light 31 to turn green, reminding the patient that the exercise is complete. During each exercise, the timing sensor in the support back plate 2 can record the time taken for the patient to complete a single exercise, allowing the patient to understand the details of their exercise. By randomly illuminating the fixed indicator light 21 and the movable indicator light 31, the patient's hand needs to be moved to different positions of the movable indicator light 31 and rotate the rotating ring 3. When the fixed indicator light 21 and the movable indicator light 31 are aligned, the hand achieves flexibility exercise. The random positions are less likely to cause the patient to develop limb inertia and memory, which is conducive to flexibly demonstrating arm flexibility and fully demonstrating arm flexibility, while also achieving upper limb strength exercise.

[0022] A number of hand-operated drive rods 33 are rotatably connected to one side of the rotating ring 3. The positions of the hand-operated drive rods 33 and the activity indicator lights 31 are one-to-one. When the activity indicator lights 31 are lit, the patient's hand is moved to the corresponding hand-operated drive rod 33, and the rotation of the rotating ring 3 is completed by pushing the hand-operated drive rod 33, which is convenient to use.

[0023] Each of the several hand-held drive rods 33 is equipped with a manual switch 34 at one end. The manual switch 34 is electrically connected to the corresponding second positioning sensor 32. The second positioning sensor 32 is controlled to be turned on by the corresponding manual switch 34. When the patient starts exercising, the fixed indicator light 21 and the active indicator light 31 light up. The patient moves his / her hand to the corresponding hand-held drive rod 33 and pushes the rotating carrier ring 3 to rotate. The active indicator light 31 and the lit fixed indicator light 21 are then aligned. At this time, the patient needs to press the manual switch 34 on the hand-held drive rod 33 to power on the corresponding second positioning sensor 32, thereby completing the sensing between the first positioning sensor 22 and the second positioning sensor 32. This allows the fixed indicator light 21 and the active indicator light 31 to change color, preventing the patient from holding other hand-held drive rods 33 and affecting the exercise effect, thus preventing cheating.

[0024] An annular groove 23 is provided on one side of the support back plate 2. A compression ring 4 is slidably connected to the inner wall of the annular groove 23. A rubber pad 41 is installed on one side of the compression ring 4. The compression ring 4 contacts one side of the rotating carrier ring 3 through the rubber pad 41. The annular groove 23 accommodates the compression ring 4, and the compression ring 4 supports the rubber pad 41. By adjusting the depth of the compression ring 4 in the annular groove 23, the contact tightness between the rubber pad 41 and the rotating carrier ring 3 can be adjusted. When the rotating carrier ring 3 rotates, it can be resisted by the rubber pad 41, thereby increasing the physical force required for the patient to push the rotating carrier ring 3 to rotate, thus assisting the patient in completing upper limb strength training.

[0025] A U-shaped support rod 42 is installed on one side of the extrusion ring 4. A resistance adjustment screw 43 is threadedly connected to the inner wall of the U-shaped support rod 42. The resistance adjustment screw 43 is rotatably connected to the back of the support back plate 2. The U-shaped support rod 42 is fixed to the extrusion ring 4. The end of the resistance adjustment screw 43 is constrained by the back of the support back plate 2. By rotating the resistance adjustment screw 43, the resistance adjustment screw 43 can drive the U-shaped support rod 42 to move closer to or away from the support back plate 2. In this way, the U-shaped support rod 42 can drive the extrusion ring 4 and the rubber pad 41 to complete the position adjustment, thereby completing the rotation resistance adjustment of the rotating carrier ring 3.

[0026] A side sliding groove 24 is provided on one side of the support back plate 2. A limiting rod 5 is slidably connected to the inner wall of the side sliding groove 24. Several insertion holes 11 are provided on the top of the support frame 1. The limiting rod 5 is inserted into the inner wall of the insertion hole 11. The side sliding groove 24 guides the limiting rod 5 to slide. After the angle between the support back plate 2 and the support frame 1 is adjusted, the limiting rod 5 is inserted into the corresponding insertion hole 11 by controlling the limiting rod 5, so that the support frame 1 can limit the angle of the support back plate 2 by the limiting rod 5, thereby improving the stability of the support back plate 2 during use.

[0027] A pull rod 51 is installed at one end of the limiting rod 5. The pull rod 51 is slidably connected to the inner wall of the side slide groove 24. A return spring 52 is installed between the pull rod 51 and the side slide groove 24. The pull rod 51 controls the limiting rod 5. The return spring 52 pushes the pull rod 51, so that the pull rod 51 can drive the limiting rod 5 to stably complete the insertion into the socket 11. When it is necessary to readjust the support back plate 2, by pulling the pull rod 51, the pull rod 51 can slide away from the support frame 1, so that the pull rod 51 can drive the limiting rod 5 to be pulled out of the socket 11 to complete the unlocking.

[0028] The working principle and usage process of this utility model are as follows: During use, by pulling the hand lever 51, the hand lever 51 can slide away from the support frame 1, allowing the hand lever 51 to drive the limiting rod 5 out of the insertion hole 11 to complete the unlocking. Then, after adjusting the angle of the support back plate 2 as needed by the user, the locking is completed. When the device is turned on, the PLC control unit inside the support back plate 2 uniformly controls several fixed indicator lights 21 and movable indicator lights 31, so that one fixed indicator light 21 and one movable indicator light 31 can be randomly illuminated at a time, displaying a red light. The patient's hand is transferred to the corresponding hand-held drive rod 33, pushing the rotating carrier ring 3 to rotate, and the movable indicator light 31 and the illuminated fixed indicator light... Once indicator light 21 is aligned, the patient needs to press the manual switch 34 on the hand-held drive rod 33 to power on the corresponding second positioning sensor 32. This allows the first positioning sensor 22 and the second positioning sensor 32 to sense each other, causing the fixed indicator light 21 and the active indicator light 31 to change color to green, reminding the patient that the exercise is complete. During each exercise session, the timing sensor in the support backplate 2 can track the time taken for the patient to complete a single exercise session, allowing the patient to understand the details of their exercise. Through multiple random lighting cycles of the fixed indicator light 21 and the active indicator light 31, the patient can flexibly move their upper limbs to different positions to complete the exercise.
