Description

Technical Field

[0001] This invention belongs to the field of medical assistive device technology, specifically relating to an adjustable limb rehabilitation device for neurology. Background Technology

[0002] The Department of Neurology primarily treats patients with cerebrovascular diseases, migraines, inflammatory brain diseases, myelitis, epilepsy, and myasthenia gravis. Some of these diseases can lead to the degeneration of motor function in the limbs, significantly impacting daily life. Therefore, these patients typically require limb training during rehabilitation to improve the overall recovery process.

[0003] Current limb rehabilitation training devices are all the same size and are not easy to adjust according to the patient's actual height, so their applicability is low. Summary of the Invention

[0004] The present invention aims to provide an adjustable limb rehabilitation device for neurology, and aims to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable limb rehabilitation device for neurology, comprising a base, a seat and a rehabilitation part disposed on the base, a slide rail disposed on the base, the seat being slidably connected to the slide rail, and a drive cylinder for driving the seat to move fixed on the base.

[0006] The rehabilitation unit includes a main body, a lower limb training device located at the bottom of the main body, and an upper limb training device located at the top of the main body. The lower limb training device includes a foot pedal rotatably connected to the main body; the upper limb training device includes a mounting block and a grip post rotatably connected to the mounting block.

[0007] The upper part of the main body is provided with an installation groove, and the installation block is vertically slidably connected in the installation groove; it also includes a threaded post that passes through the installation block and is threadedly connected to the installation block, the threaded post passes through the top of the main body, and the threaded post is rotatably connected to the main body, and a motor that drives the threaded post to rotate is fixed on the top of the main body.

[0008] The beneficial effects of this technical solution are:

[0009] The seat is moved by a drive cylinder, allowing the distance between the seat and the rehabilitation unit to be adjusted according to the patient's height or actual needs, facilitating rehabilitation training. The patient places their feet on the footrests and uses their feet to rotate the footrests, exercising the lower limbs and completing lower limb rehabilitation training. The patient's hands grip the grip posts and rotate them, exercising the upper limbs and completing upper limb rehabilitation training.

[0010] Furthermore, during rehabilitation training, the screw column can be rotated by a motor, and the screw column and the mounting block form a lead screw structure, which enables the mounting block to move back and forth in the mounting slot, thereby adjusting the position of the mounting block and adjusting the grip column to a suitable position.

[0011] In summary, this technical solution can adjust the distance between the patient and the rehabilitation unit, as well as the height of the upper limb training equipment, thereby adapting to patients of different heights and improving applicability.

[0012] In another preferred embodiment of the present invention, a rotating component is connected to both the foot pedal and the grip post. The rotating component includes a rotating wheel and a force adjustment structure, and both the foot pedal and the grip post are fixed on the rotating wheel.

[0013] Beneficial effects: By adjusting the force-adjusting structure, the force required when the rotating wheel rotates can be adjusted, thereby adapting to different stages of rehabilitation training.

[0014] In another preferred embodiment of the present invention, the force adjustment structure includes two adjustment blocks located inside the rotating wheel. One end of the two adjustment blocks is hinged together, and a driving block is provided between the free ends of the two adjustment blocks. The driving block includes a block body and support balls provided at both ends of the block body. A cavity is provided inside the block body, and an elliptical driving ball is provided inside the cavity. A rotating shaft is fixed in the middle of the driving ball. Movable blocks are fixed at both ends of the block body. The support balls are rotatably connected to the movable blocks, and the driving balls abut against the movable blocks.

[0015] Beneficial effects: The rotation of the rotating shaft can drive the drive ball to rotate, which in turn drives the support ball to move. This changes the distance and force between the adjusting block and the inner side of the rotating wheel, thereby adjusting the resistance encountered when the rotating wheel rotates. This allows for adjustment of the force required by the hands and feet during rehabilitation training, adapting to different stages of rehabilitation training.

[0016] In another preferred embodiment of the present invention, a buffer spring is provided between the two adjusting blocks.

[0017] Beneficial effect: The buffer spring can play a buffering role.

[0018] In another preferred embodiment of the present invention, a drive shaft is threadedly connected to both the main body and the mounting block. A drive bevel gear is connected to the drive shaft via a spline, and a driven bevel gear that meshes with the drive bevel gear is coaxially fixed to both the rotating shaft and the drive bevel gear.

[0019] Beneficial effects: Rotating the drive shaft drives the active bevel gear to rotate. Through the transmission between the active and driven bevel gears, the drive shaft drives the drive ball to rotate, thereby adjusting the position of the adjusting block. Furthermore, the drive shaft is threaded onto the main body and the mounting block, providing a locking function. The drive ball rotates under inertia, ensuring stability during rehabilitation training.

[0020] In another preferred embodiment of the present invention, a protrusion parallel to the end face of the rotating wheel is provided on one side of the adjusting block, an oil guiding channel is provided inside the protrusion, one end of the oil guiding channel passes through the side of the protrusion connected to the adjusting block, and an oil storage part communicating with the oil guiding channel is also included.

[0021] Beneficial effects: By introducing lubricating oil through the oil reservoir and oil guide channel, the surface of the adjusting block is covered with lubricating oil, which can prevent the rotating wheel from getting stuck and reduce the wear of the rotating wheel and the adjusting block.

[0022] In another preferred embodiment of the present invention, the oil storage part includes an oil storage cavity disposed above the block, the oil storage cavity communicating with the cavity of the block, and the cavity communicating with the oil guiding channel; the inner wall of the cavity is provided with a compression film and a compression block attached to the compression film, and a compression rod is fixed on the compression block, penetrating the side wall of the cavity and slidably connected to the side wall of the cavity; a plurality of wedge blocks for driving the compression block to move are disposed on the side of the rotating wheel that is attached to the protrusion.

[0023] Beneficial effects: When the rotating wheel rotates, it drives the wedge block to rotate, which in turn contacts the extrusion rod through the wedge surface of the wedge block, gradually moving the extrusion block. This allows the extrusion film to extrude the lubricating oil in the cavity, and the lubricating oil can be discharged through the oil guide channel, thus lubricating the rotating wheel and the adjusting block. Moreover, lubricating oil can be replenished into the cavity through the oil storage chamber.

[0024] The cavity is filled with lubricating oil, which provides lubrication for the drive ball.

[0025] In another preferred embodiment of the present invention, a return spring is provided between the extrusion block and the inner wall of the block.

[0026] Beneficial effect: When the squeezing force of the wedge block on the squeezing rod disappears, the squeezing block can automatically reset.

[0027] In another preferred embodiment of the present invention, a Tesla valve is provided at the connection between the oil storage chamber and the cavity.

[0028] Beneficial effects: The Tesla valve facilitates the introduction of lubricating oil from the oil reservoir into the cavity, and when the cavity is compressed, the lubricating oil in the cavity is less likely to flow back into the oil reservoir, making it easier to lubricate the rotating wheel and adjusting block through the oil guide channel.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0041] This invention provides an adjustable limb rehabilitation device for neurology, such as... Figure 1 As shown, the device includes a base 1, a seat 2, and a rehabilitation unit. A slide rail is provided on the left side of the upper surface of the base 1, and the seat 2 is laterally slidably connected to the slide rail. A drive cylinder 3 is provided on the left side of the base 1. The push rod of the drive cylinder 3 is fixed to the left end of the seat 2, so the seat 2 can be slid laterally through the cylinder, thereby adjusting the position of the seat 2.

[0042] The rehabilitation unit is located on the right side of the seat 2, and includes a main body 4, lower limb training components and upper limb training components. The main body 4 is fixed on the base 1.

[0043] The lower limb training device includes two foot pedals 5 and two rotating components; the upper limb training device includes a mounting block 6, two grip posts 7, and two rotating components. The rotating components of both the lower limb and upper limb training devices are identical. Both the main body 4 and the mounting block 6 have cavities for housing the rotating components. Figure 2 As shown, the rotating component includes a rotating wheel 8 disposed in the cavity and a force adjustment structure, with the rotating wheel 8 rotatably connected to the cavity.

[0044] Both the upper limb and lower limb training components have coaxial grooves 9 on opposite sides of their rotating wheels 8, and the force adjustment structure is located within these grooves 9. The grip post 7 and foot pedal 5 are fixed to the side of the rotating wheels 8 without grooves 9. The force adjustment structure includes two adjusting blocks 10, both of which are arc-shaped. A buffer spring 11 is located between the two driving blocks; in this embodiment, a compression spring is used, and the specific model is selected according to actual needs. The right ends of the two adjusting blocks 10 are hinged; a driving block is located between the left ends of the two adjusting blocks 10, and the driving block is fixed within the cavity. Figure 3As shown, the drive block includes a block body 12 and two support balls 13. A cavity 14 is provided inside the block body 12. It also includes a movable block 15 that passes through the upper and lower ends of the block body 12 and is vertically slidably connected to the block body 12. The support balls 13 are rotatably connected to the ends of the two movable blocks 15 located outside the block body 12, and the two support balls 13 are respectively attached to the left ends of the two adjustment blocks 10.

[0045] The cavity 14 is filled with lubricating oil; the movable block 15 is provided with an anti-detachment block 16 and a sealing flexible sheet 17 at one end inside the cavity 14. The middle part of the sealing flexible sheet 17 is fixed on the movable block 15, and the outer periphery of the sealing flexible sheet 17 is fixed inside the cavity 14. Therefore, it can prevent the movable block 15 from falling off the block 12, and at the same time, it can prevent the lubricating oil in the cavity 14 from leaking.

[0046] An elliptical drive ball 18 is disposed between two movable blocks 15 inside the cavity 14. A drive groove is provided on the outer periphery of the drive ball 18. A sliding block is provided on one end of each movable block 15 inside the cavity 14. The sliding block is slidably connected in the drive groove. Therefore, when the drive ball 18 rotates, it can drive the movable block 15 to move vertically. Furthermore, the lubrication of the lubricating oil inside the cavity 14 can reduce jamming.

[0047] A rotating shaft 19 is fixed to the middle of the drive ball 18, and the rotating shaft 19 passes through the block 12 and is rotatably connected to the block 12. It also includes a drive shaft 20 for driving the rotating shaft 19 to rotate, and the drive shaft 20 of the upper limb training piece passes through the left side of the mounting block 6. Figure 1 The drive shaft 20 extends into the cavity and is threadedly connected to the mounting block 6; the drive shaft 20 of the lower limb training piece passes through the left side of the main body 4. Figure 1 (Middle) and extends into the cavity, and the drive shaft 20 is threadedly connected to the main body 4. The drive shaft 20 is perpendicular to the rotation shaft 19, and the drive shaft 20 is located between the two rotation shafts 19 of the upper limb training piece, combined with Figure 4 As shown, the drive shaft 20 is connected to the drive bevel gear 21 via a spline at one end of the cavity. The drive bevel gear 21 is rotatably connected to the cavity. The driven bevel gear 22 that meshes with the drive bevel gear 21 is provided at the end of the two rotating shafts 19 that are close to each other.

[0048] The main body 4 is also provided with a vertical mounting groove 23, and the mounting block 6 is vertically slidably connected in the mounting groove 23. A threaded post 24 is threadedly connected to the mounting block 6, and the bottom end of the threaded post 24 passes through the mounting block 6 and is rotatably connected to the bottom of the mounting groove 23. A through hole 25 is provided at the top of the main body 4, and the threaded post 24 passes through the through hole 25. A motor 26 is fixed at the top of the main body 4. The motor 26 is a forward and reverse reversible motor. The output shaft of the motor 26 is coaxially fixed with the threaded post 24, so it can drive the threaded post 24 to rotate.

[0049] The specific implementation process is as follows:

[0050] During rehabilitation training, the patient sits on seat 2 and moves seat 2 by means of a cylinder, thereby adjusting the distance between seat 2 and rehabilitation unit; then the electric motor is activated, and motor 26 drives threaded column 24 to rotate, so that mounting block 6 moves vertically, adjusting the height of upper limb training piece, thereby adapting to different patients for rehabilitation training.

[0051] The patient places their feet on foot pedal 5, rotating the pedal to achieve foot rehabilitation training. The patient's hands grasp and rotate the grip post 7 to achieve hand rehabilitation training. This completes the rehabilitation training for both the upper and lower limbs.

[0052] During training, the force adjustment structure can be adjusted to regulate the force required to rotate the foot pedal 5 and grip column 7, thus adapting to different patients and different stages of rehabilitation training.

[0053] Rotating the drive shaft 20 causes the drive ball 18 to rotate under the transmission of the driving bevel gear 21 and the driven bevel gear 22. Since the drive ball 18 is elliptical, when it rotates, it drives the moving block 15 to move, which in turn drives the support ball 13 to move. This causes the support ball 13 to move the free end of the adjusting block 10, thereby adjusting the distance between the adjusting block 10 and the inner ring of the rotating wheel 8. As the adjusting block 10 comes into contact with or even presses against the inner ring of the rotating wheel 8, the force required to rotate the rotating wheel 8 gradually increases, thus adapting to more different rehabilitation training.

[0054] Example 2:

[0055] The only difference between Example 2 and Example 1 is that, as Figure 5 As shown, in this embodiment, the top of the upper adjusting block 10 is provided with a protrusion 27. The protrusion 27 is in contact with the end face (front end face) of the rotating wheel 8 which is provided with a groove 9. An oil guiding channel 28 is provided in the protrusion 27. The left end of the oil guiding channel 28 is connected to the outside, so the lubricating oil can be guided to the surface of the adjusting block 10. When the adjusting block 10 is in contact with the inner ring of the rotating wheel 8, it plays a lubricating role.

[0056] An oil guide pipe 29 is connected to the oil guide channel 28. The oil guide pipe 29 is connected to the cavity 14 of the block 12, allowing lubricating oil in the cavity 14 to be guided into the oil guide channel 28. It also includes an oil storage section, which includes an oil storage chamber 30. The oil storage chamber 30 of the upper limb training component is located within the mounting block 6, and the oil storage chamber 30 of the lower limb training component is located within the main body 4. Both the main body 4 and the mounting block 6 are provided with replenishment holes communicating with the oil storage chamber 30. A sealing plug is installed in the replenishment hole, allowing lubricating oil to be replenished into the oil storage chamber 30 through the replenishment hole.

[0057] An oil filling pipe 31 is connected to the oil storage chamber 30, and the bottom end of the oil filling pipe 31 is connected to the cavity 14. A Tesla valve is installed inside the oil filling pipe 31 to facilitate the introduction of lubricating oil from the oil storage chamber 30 into the cavity 14.

[0058] Combination Figure 6 As shown, a compression film 32 is provided on the inner wall of cavity 14. The right side of the compression film 32 and the right side wall of cavity 14 form a sealed cavity 14. A compression block 33 is fixed to the right side wall of compression film 32. A compression rod 34 is fixed to the right end of compression block 33. Compression rod 34 penetrates the side wall of block 12 and is laterally slidably connected to block 12. Multiple wedge blocks 35 are provided on the front end face of rotating wheel 8. The wedge surface of wedge block 35 faces the inside of rotating wheel 8, and the wedge surface of wedge block 35 can be in contact with compression rod 34, thus generating a compression force on compression rod 34 and driving compression block 33 to move. A return spring is provided between compression block 33 and inner wall of cavity 14.

[0059] During rehabilitation training, the grip column 7 or foot pedal 5 drives the rotating wheel 8 to rotate, which causes the wedge block 35 to intermittently push the extrusion rod 34. The extrusion block 33 drives the extrusion film 32 to move, and in conjunction with the Tesla valve, the lubricating oil in the cavity 14 is squeezed into the oil guide channel 28 and moved to the surface of the upper adjustment block 10, thereby playing a lubricating role.
