Description

Technical Field

[0001] This invention relates to the field of upper limb mirror rehabilitation, specifically to an upper limb mirror rehabilitation exercise device and method. Background Technology

[0002] Upper limb mirror rehabilitation is a treatment technique based on visual stimulation and using the principle of plane mirror imaging to copy the image of the non-paralyzed limb movement to the paralyzed side, allowing the patient to imagine the movement of the paralyzed limb. It is a treatment technique that combines visual illusion, visual feedback, and scenario simulation with rehabilitation training. By having the patient observe the movement of the normal limb, they can imitate it, thereby strengthening the brain's impression of the limb movement.

[0003] The following problems were found in the existing equipment that have not been adequately addressed: Generally, when using the equipment, patients rely on the mirror image to assist them in performing limb movements. However, some patients have difficulty performing these movements and exerting force to complete them, making it inconvenient for them to conduct rehabilitation training on their own. Furthermore, the training devices are relatively limited in scope, with only a few training programs available. It is necessary to replace the equipment to perform other training programs, which makes the devices inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide an upper limb mirror rehabilitation exercise device and method to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: an upper limb mirror rehabilitation exercise device, including a support base, a support frame fixedly connected to the top of the support base, and an installation cavity formed in the inner wall of the support frame;

[0005] The inner wall of the mounting cavity is rotatably connected to a first gear, and a second gear meshes with one side of the first gear. Both the first gear and the second gear are equipped with arm training devices for upper limb arm extension exercises.

[0006] The lower end of the arm training device is equipped with a hand training device for hand exercises.

[0007] Preferably, the arm training device includes two symmetrically arranged extended arms, which are fixedly connected to the first gear and the second gear respectively. Each of the two extended arms has a swing arm hinged to its front end, and a positioning rod is hinged to one side of each swing arm. Both positioning rods are rotatably connected to the inner wall of the support frame.

[0008] The bottom ends of both the deploying arm and the swing arm are fixedly connected to a placement frame.

[0009] Preferably, the arm training device further includes an internal tooth groove, and a power wheel is hinged to the front end of the internal tooth groove. A transmission rod is hinged to the top end of the power wheel, and a pressing plate is fixedly connected to the top end of the transmission rod. A wire-passing wheel is rotatably connected to the inner wall of the pressing plate.

[0010] The extrusion plate is configured with a spring-loaded telescopic structure.

[0011] Preferably, the hand training device includes a rotating cavity formed inside the swing arm, a rotating sleeve rotatably connected to the inner wall of the rotating cavity, an inner arc groove formed in the inner wall of the rotating sleeve, a pushing block slidably connected to the inner wall of the rotating sleeve, and a protrusion fixedly connected to the side wall of the pushing block. The bottom end of the pushing block is fixedly connected to the bottom wall of the rotating sleeve by a spring, and the protrusion is slidably connected to the inner arc groove.

[0012] A steel cable is installed through the inner wall of the push block, and a limit block is fixedly connected to the outer wall of the steel cable.

[0013] Preferably, the hand training device further includes a handrail frame fixedly connected to the bottom end of the rotating sleeve, a grip rod rotatably connected to the inner wall of the handrail frame, and tension lines fixedly connected to both ends of the grip rod. Several tensioning wheels arranged horizontally at equal intervals are fixedly connected to the top wall of the handrail frame, and the tensioning lines are connected to the tensioning wheels. The end of the tensioning line is fixedly connected to the bottom end of the steel cable.

[0014] The outer wall of the steel cable extends through the outer wall of the swing arm, and one end of the steel cable passes through the inner wall of the guide wheel. A winding wheel is wound around one side of the steel cable, and a guide wheel with the same structure is horizontally arranged on one side of the winding wheel. The steel cable passes through the guide wheel and extends into the rotating sleeve in the left swing arm.

[0015] The top end of the grip rod is slidably connected to several horizontally arranged plug plates at equal intervals, and the bottom end of the grip rod is slidably connected to a plug plate with the same structure.

[0016] Preferably, the rotating sleeve is provided in two sets, and the two sets of rotating sleeves are respectively opened in the inner wall of the two swing arms. The inner arc groove in the right rotating sleeve is inclined from left to right, and the limiting block in the right rotating sleeve is located at the top of the pushing block.

[0017] The limiting block in the rotating sleeve on the left is located at the bottom of the pushing block.

[0018] Preferably, the hand training device further includes a limiting frame slidably connected to the inner wall of the gripping rod. One end of the limiting frame is fixedly connected to a spring telescopic rod, and the end of the spring telescopic rod is fixedly connected to the bottom end of the gripping rod. The inner wall of the limiting frame and the outer wall of the plug-in plate are connected by a spline. A slider is attached to the top of the limiting frame and is slidably connected to the inner wall of the limiting frame. A telescopic lever is hinged to the outer wall of the slider, and the shaft end of the telescopic lever is rotatably connected to the inner wall of the limiting frame. A toothed plate is hinged to the end of the telescopic lever and slides in the inner wall of the limiting frame. A torsion spring is sleeved on the shaft end of the telescopic lever.

[0019] A take-up roller is rotatably connected to the inner wall of the limiting frame, and a torsion spring is sleeved on the shaft end of the take-up roller. A gear groove matching the inner tooth groove of the toothed plate is opened on the outer wall of the take-up roller. A trigger wire is wound on the outer wall of the take-up roller and passes through the interior of the left end gripping rod. A wedge block is fixedly connected to the end of the trigger wire. A trapezoidal block is attached to the front end of the wedge block. A sliding plate is fixedly connected to the outer wall of the trapezoidal block, and a limiting rod is passed through the outer wall of the sliding plate. A return spring is sleeved on the outer wall of the limiting rod. The bottom end of the trapezoidal block is attached to the plug-in plate, and a spring is fixedly connected to one end of the plug-in plate. One end of the spring is fixedly connected to the inner wall of the gripping rod.

[0020] Preferably, the front end of the support base is slidably connected to an extension plate, and the top end of the extension plate is fixedly connected to a mounting bracket, and a mirror plate is fixedly connected to the mounting bracket.

[0021] A method for using an upper limb mirror rehabilitation exercise device includes the following steps:

[0022] S1. The patient stands or sits on the support base, with their hands passing through the placement frame, connecting their arms to the extended arms and swing arms. The patient can then swing their movable arms. At this time, the first gear on the extended arm can drive the second gear to rotate. The second gear rotates in the opposite direction to the first gear, causing the two extended arms to be in an extended and relaxed state. While performing the movement, the patient can watch the mirror board and observe the movement of their own arms in the mirror board, increasing the brain's feedback.

[0023] S2. Simultaneously, the patient passes their hand through the placement frame and inserts their fingers into the insertion plate, thus fixing their palm on the grip bar. The patient rotates one side of the grip bar, pulling the tension line. The tension line moves downward through the tension wheel, pulling the upper steel cable. At this time, because the inner arc groove in the right rotating sleeve is inclined from left to right, and the limiting block in the right rotating sleeve is located at the top of the pushing block, when the steel cable moves downward, the limiting block on the steel cable will move down and push the pushing block. The protrusion on the pushing block moves down and pushes the rotating sleeve to the left through the inner tooth groove. At this time, the handrail frame will rotate.

[0024] S3. Simultaneously, as the tension line drives the steel cable downward, the steel cable pulls the winding wheel to rotate, and the other end of the steel cable pulls the push block in the left rotating cavity. The protrusion on the push block moves upward, thereby driving the rotating sleeve to rotate to the right, so that the patient can rotate in another direction when rotating the wrist, which facilitates multi-directional rotation.

[0025] S4. Then, as the unfolding arm and the swing arm rotate, the internal tooth groove in the unfolding arm drives the power wheel to rotate. The power wheel drives the compression plate to rotate. The thread-passing wheel on the compression plate can compress the steel cable, so that the steel cable can be tightened when rotation occurs, making it easier for the patient to operate.

[0026] S5. Finally, the patient can push upward with their thumb, which pushes the plug plate, which in turn pushes the slider to rise. The slider then pushes the telescopic lever, which retracts itself and pulls the toothed plate downward. The toothed plate separates from the gear groove on the outer wall of the take-up roller, and the take-up roller is no longer restricted by the toothed plate. At this point, when performing the arm extension movement, there will be no interference.

[0027] When the patient completes the arm extension, they can pull back the retaining plate to lock the take-up roller. When the patient pulls the insert plate to one side, the spline connection between the insert plate and the limit frame causes the limit frame to move synchronously. The limit frame drives the take-up roller to move together, triggering the trigger line on the take-up roller. Pulling the wedge block pushes the trapezoidal block downwards, and the downward movement of the trapezoidal block pushes the insert plate to move in the opposite direction, enabling finger exercises. Furthermore, the setting of several slidable insert plates allows for independent exercises of other fingers.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In this invention, by setting up an extended arm and a swinging arm, the paralyzed part of the patient can be passively moved, assisting the patient in arm movements and exercise, and facilitating the patient's rehabilitation training.

[0030] In this invention, the hand training device can drive the armrest to rotate in different directions when the patient rotates their wrist, making it convenient for hand exercises.

[0031] In this invention, by setting up arm training devices and hand training devices, various training methods can be performed, adapting to various training environments and facilitating the use of the device. Attached Figure Description

[0043] 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.

[0044] Please see Figures 1 to 10 The present invention provides a technical solution: an upper limb mirror rehabilitation exercise device, including a support base 1, a support frame fixedly connected to the top of the support base 1, and an installation cavity 2 opened in the inner wall of the support frame;

[0045] The inner wall of the mounting cavity 2 is rotatably connected to a first gear 3, and a second gear 4 is meshed on one side of the first gear 3. Both the first gear 3 and the second gear 4 are equipped with arm training devices for upper limb arm extension exercises.

[0046] The lower end of the arm training device is equipped with a hand training device for hand exercises.

[0047] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the arm training device includes two symmetrically arranged extended arms 5. The two extended arms 5 are fixedly connected to the first gear 3 and the second gear 4 respectively. The front end of each of the two extended arms 5 is hinged with a swing arm 6. A positioning rod 7 is hinged to one side of each of the two swing arms 6. Both positioning rods 7 are rotatably connected to the inner wall of the support frame.

[0048] The bottom ends of the two extending arms 5 and the swinging arm 6 are fixedly connected to the placement frame 8, so that when the patient swings one arm, the other arm can be driven to move.

[0049] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the arm training device also includes an inner toothed groove 9, and a power wheel 10 is hinged to the front end of the inner toothed groove 9. A transmission rod 11 is hinged to the top end of the power wheel 10, and a pressing plate 12 is fixedly connected to the top end of the transmission rod 11. A thread-passing wheel 13 is rotatably connected to the inner wall of the pressing plate 12.

[0050] The extrusion plate 12 is a spring telescopic structure. The extrusion plate 12, which is elastically telescopic, can rotate and tension the steel cable 19 when the unfolding plate and the swing arm 6 rotate, so as to prevent it from loosening.

[0051] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the hand training device includes a rotating cavity 14 inside the swing arm 6. A rotating sleeve 15 is rotatably connected to the inner wall of the rotating cavity 14. An inner arc groove 16 is provided in the inner wall of the rotating sleeve 15. A push block 17 is slidably connected to the inner wall of the rotating sleeve 15. A protrusion 18 is fixedly connected to the side wall of the push block 17. The bottom end of the push block 17 is fixedly connected to the bottom wall of the rotating sleeve 15 by a spring. The protrusion 18 is slidably connected to the inner arc groove 16.

[0052] A steel cable 19 is installed through the inner wall of the push block 17, and a limit block 20 is fixedly connected to the outer wall of the steel cable 19. When the patient rotates the grip bar 22, the handrail frame 21 is rotated simultaneously to train the wrist.

[0053] In this embodiment, as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the hand training device also includes a handrail 21 fixedly connected to the bottom of the rotating sleeve 15. A grip rod 22 is rotatably connected to the inner wall of the handrail 21, and tension lines 23 are fixedly connected to both ends of the grip rod 22. Several tension wheels 24 are fixedly connected to the top wall of the handrail 21 and are arranged horizontally at equal intervals. The tension lines 23 are connected to the tension wheels 24, and the end of the tension line 23 is fixedly connected to the bottom of the steel cable 19.

[0054] The outer wall of the steel cable 19 extends through the outer wall of the swing arm 6, and one end of the steel cable 19 passes through the inner wall of the guide wheel 13. One side of the steel cable 19 is wound with a winding wheel 25, and a guide wheel 13 with the same structure is horizontally arranged on one side of the winding wheel 25. The steel cable 19 passes through the guide wheel 13 and extends into the rotating sleeve 15 in the left swing arm 6.

[0055] The top of the grip rod 22 is slidably connected to several horizontally arranged plug plates 26 at equal intervals, and the bottom of the grip rod 22 is slidably connected to a plug plate 26 with the same structure. With the setting of two handrails 21, when the patient rotates the grip rod 22 at one end, it can drive the grip rod 22 at the other end to rotate horizontally, which can assist in applying force and facilitate the patient's training.

[0056] In this embodiment, as Figure 8 , Figure 9 and Figure 10 As shown, there are two sets of rotating sleeves 15, and the two sets of rotating sleeves 15 are respectively opened in the inner wall of the two swing arms 6. The inner arc groove 16 in the right rotating sleeve 15 is inclined from left to right, and the limiting block 20 in the right rotating sleeve 15 is located at the top of the pushing block 17.

[0057] The limiting block 20 in the left rotating sleeve 15 is located at the bottom of the pushing block 17, so that when the steel cable 19 is pulled, the two sets of handrail frames 21 can be driven to rotate synchronously.

[0058] In this embodiment, as Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the hand training device also includes a limiting frame 27 slidably connected to the inner wall of the gripping rod 22. One end of the limiting frame 27 is fixedly connected to a spring telescopic rod 28, and the end of the spring telescopic rod 28 is fixedly connected to the bottom end of the gripping rod 22. The inner wall of the limiting frame 27 and the outer wall of the plug-in plate 26 are connected by a spline. The top of the limiting frame 27 is fitted with a slider 29, which is slidably connected to the inner wall of the limiting frame 27. A telescopic lever is hinged to the outer wall of the slider 29. The shaft end of the telescopic lever 30 is rotatably connected to the inner wall of the limiting frame 27. A toothed plate 31 is hinged to the end of the telescopic lever 30, and the toothed plate 31 slides in the inner wall of the limiting frame 27. A torsion spring is sleeved on the shaft end of the telescopic lever 30.

[0059] A take-up roller 32 is rotatably connected to the inner wall of the limiting frame 27. A torsion spring is sleeved on the shaft end of the take-up roller 32, and a gear groove 33 matching the inner tooth groove 9 of the toothed plate 31 is opened on the outer wall of the take-up roller 32. A trigger wire 34 is wound on the outer wall of the take-up roller 32 and passes through the interior of the left end gripping rod 22. A wedge block 35 is fixedly connected to the end of the trigger wire 34. A trapezoidal block 36 is attached to the front end of the wedge block 35. A sliding plate 37 is fixedly connected to the outer wall of the trapezoidal block 36, and a limiting rod 38 is provided through the outer wall of the sliding plate 37. A return spring 39 is sleeved on the outer wall of the limiting rod 38. The bottom end of the trapezoidal block 36 is connected to the insertion plate 26. The connection is snug, and one end of the plug plate 26 is fixedly connected to a spring, and one end of the spring is fixedly connected to the inner wall of the grip rod 22. The patient can pull back the toothed plate 31, so that the take-up roller 32 is locked. When the patient pulls the plug plate 26 to one side, due to the spline connection between the plug plate 26 and the limiting frame 27, the limiting frame 27 moves synchronously. The limiting frame 27 drives the take-up roller 32 to move together. The trigger line 34 on the take-up roller 32 pulls the wedge block 35 to push the trapezoidal block 36 to move downward. The downward movement of the trapezoidal block 36 pushes the plug plate 26 to move in the opposite direction, which can exercise the fingers. The setting of several slidable plug plates 26 can also allow for independent exercise of other fingers.

[0060] In this embodiment, as Figure 1 and Figure 2 As shown, an extension plate is slidably connected to the front end of the support base 1, and a mounting bracket is fixedly connected to the top of the extension plate. A mirror plate is fixedly connected to the mounting bracket. The mirror plate allows patients to easily observe the movement process of their upper limbs, increasing the brain's memory of the movement sensation.

[0061] In this embodiment, as Figures 1 to 10 As shown, a method of using an upper limb mirror rehabilitation exercise device includes the following steps:

[0062] S1. The patient stands or sits on the support base 1, with their hands passing through the placement frame 8, connecting their arms to the extension arm 5 and the swing arm 6. At this time, the patient can swing their movable arm. The first gear 3 on the extension arm 5 can drive the second gear 4 to rotate. The rotation direction of the second gear 4 is opposite to that of the first gear 3, so that the two extension arms 5 are in an extended and stretched state. When the patient performs the movement, they can watch the mirror board and see the movement of their own arms in the mirror board, which increases the feedback to the brain.

[0063] S2. Simultaneously, the patient passes their hand through the placement frame 8 and inserts their fingers into the insertion plate 26, so that their palm is fixed on the grip rod 22. The patient rotates one side of the grip rod 22, and the grip rod 22 pulls the tension line 23. The tension line 23 moves downward through the tension wheel 24, pulling the upper steel cable 19. At this time, because the inner arc groove 16 in the right rotating sleeve 15 is inclined from left to right, and the limiting block 20 in the right rotating sleeve 15 is located at the top of the push block 17, when the steel cable 19 moves downward, the limiting block 20 on the steel cable 19 will move down and push the push block 17. The protrusion 18 on the push block 17 moves down and pushes the rotating sleeve 15 to rotate to the left through the inner tooth groove 9. At this time, the handrail frame 21 will rotate.

[0064] S3. Simultaneously, as the tension line 23 drives the steel cable 19 to move downward, the steel cable 19 pulls the winding wheel 25 to rotate. The other end of the steel cable 19 pulls the push block 17 in the left rotating cavity 14, and the protrusion 18 on the push block 17 moves upward, thereby driving the rotating sleeve 15 to rotate to the right. This allows the patient to rotate in another direction when rotating their wrist, making it easier to rotate in multiple directions.

[0065] S4. Then, when the unfolding arm 5 and the swing arm 6 rotate, the internal tooth groove 9 in the unfolding arm 5 drives the power wheel 10 to rotate. The power wheel 10 drives the compression plate 12 to rotate. The thread guide wheel 13 on the compression plate 12 can compress the steel cable 19, so that the steel cable 19 can be tightened when rotation occurs, making it easier for the patient to operate.

[0066] S5. Finally, the patient can push upward with their thumb. The thumb pushes the plug plate 26, the plug plate 26 pushes the slider 29 to rise, the slider 29 pushes the telescopic lever, the telescopic lever 30 retracts itself and pulls the toothed plate 31 downward. The toothed plate 31 separates from the gear groove 33 on the outer wall of the take-up roller 32. The take-up roller 32 is no longer restricted by the toothed plate 31. At this time, when performing the arm extension movement, there will be no interference.

[0067] When the patient completes the arm extension, the patient can pull back the retaining plate 31, locking the take-up roller 32. When the patient pulls the plug plate 26 to one side, the plug plate 26 and the limit frame 27 are splinedly connected, causing the limit frame 27 to move synchronously. The limit frame 27 drives the take-up roller 32 to move together. The trigger line 34 on the take-up roller 32 pulls the wedge block 35, pushing the trapezoidal block 36 downward. The downward movement of the trapezoidal block 36 pushes the plug plate 26 to move in the opposite direction, enabling finger exercises. Furthermore, the setting of several slidable plug plates 26 allows for independent exercises of other fingers.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
