Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic rehabilitation training, in particular to an orthopedic rehabilitation training auxiliary device. Background Art

[0002] Orthopedic rehabilitation is a rehabilitation treatment used to help patients recover from functional impairments caused by injuries or diseases of the bones, muscles, joints, ligaments, tendons, and other muscular systems. This is because during illness or injury, the muscles in the affected area often atrophy and weaken due to prolonged immobilization and disuse.

[0003] In order to be able to conduct rehabilitation training for patients scientifically, targeted arrangements will be made based on the patient's specific condition, rehabilitation stage, physical condition and other factors. For example, patients with severe conditions who are unable to actively move their joints in the early stages need passive joint mobility training. When the condition has improved and they have a certain degree of independent movement ability, active joint mobility training will be carried out. In the later stages of rehabilitation, patients will undergo relatively difficult training, such as stair climbing training. Patients need to learn the correct posture and skills for going up and down stairs, such as taking the healthy leg first when going upstairs and the affected leg first when going downstairs. For patients recovering from knee injuries, stair climbing training can help them restore their normal gait and improve the motor ability of the lower limbs.

[0004] To assist medical staff and patients with rehabilitation training, a wide range of orthopedic training aids have emerged on the market, including CPM machines, range of motion trainers, resistance bands, isokinetic muscle trainers, balance boards, and gait training belts. These devices are primarily used for range of motion training, muscle strength training, and balance training, while assistive devices for stair climbing and descending training are virtually nonexistent.

[0005] Currently, the method used for stair climbing and descending training for patients is that patients are protected by staff in rehabilitation training centers or residential areas while they complete stair climbing and descending training on building stairs. This training method has some drawbacks. For example, since patients' lower limb muscles are often weak, they may not be able to properly support their bodies to complete the movements of climbing and descending stairs. Their balance ability is also poor, and they are prone to losing balance and falling during the process. Therefore, staff are required to support and assist them in completing the stair climbing and descending training task. This prevents the assisting staff from performing other tasks, resulting in high costs. In addition, the number of stairs attached to the building is limited. If there are many people undergoing orthopedic rehabilitation training, the number of staff assisting in the rehabilitation training is insufficient, and it is impossible for multiple people to perform stair climbing and descending training at the same time, which affects the progress of the rehabilitation training task.

DETAILED DESCRIPTION

[0035] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0037] Example 1

[0038] like Figure 1-8 、 Figure 10-13 As shown, in order to meet the rehabilitation training needs of multiple rehabilitation personnel for going up and down stairs and at the same time reduce the time staff spend caring for a single rehabilitation personnel, this embodiment provides auxiliary equipment for training going up and down stairs. Multiple sets of such auxiliary devices can be set up in a rehabilitation training center. Rehabilitation personnel can complete training going up and down stairs on the auxiliary devices, and at the same time provide protection for rehabilitation personnel to prevent them from rolling off the device due to unstable center of gravity.

[0039] Specifically, the auxiliary device includes a rehabilitation ladder 1 and a protective assembly. A bracket is installed beneath the rehabilitation ladder 1, which stabilizes the ladder 1 in the rehabilitation center. The bracket can be pulled to control the movement of the ladder 1, achieving adjustable position. The protective assembly is mounted on the handrails of the rehabilitation ladder 1 and can be raised and lowered along the handrails. Therefore, the protective assembly adjusts its position relative to the ladder 1 as the rehabilitation patient ascends or descends, providing full protection for the patient throughout the entire process.

[0040] To ensure the protection assembly is stably mounted on the rehabilitation ladder 1, a guide rail 11 is provided on the side of the rehabilitation ladder 1, and the guide rail 11 is arranged along the inclination direction of the rehabilitation ladder 1. The protection assembly is arranged across the handrail of the rehabilitation ladder 1 and the guide rail 11, increasing the stability of the protection assembly when walking.

[0041] In order to protect the rehabilitation personnel through the protection component, the protection component includes a walking mechanism 3, a motor 2, a support frame 5, a protection mechanism 4, an industrial camera 22 and a control box 21. The walking mechanism 3 is directly arranged with the handrail and the guide rail 11 of the rehabilitation ladder 1, that is, the walking mechanism 3 is arranged across the handrail and the guide rail 11, and can move along the handrail and the guide rail 11. The motor 2 is fixedly arranged on the side of the walking mechanism 3 and can control the movement of the walking mechanism 3, so that it can control the movement of the walking mechanism 3 according to the operation of the motor 2. The support frame 5 is vertically and detachably arranged on the walking mechanism 3, and is arranged as an L-shaped structure with adjustable height. At the same time, the protection mechanism 4 is arranged on the top of the support frame 5. In addition, the protection mechanism 4 is worn on the rehabilitation personnel. Therefore, when the walking mechanism 3 moves with the rehabilitation personnel, the support frame 5 and the protection mechanism 4 are controlled to move synchronously, so as to provide protection for the rehabilitation personnel and prevent their presence from affecting the lifting and lowering movement of the rehabilitation personnel. The industrial camera 22 and the control box 21 are both set on the support frame 5. The control box 21 is equipped with a controller (such as PLC), a memory, various interfaces, etc., so that the motor 2 can be controlled by the control box 21, and the information transmitted by the industrial camera 22 can be received, so as to obtain the position of the rehabilitation person through the industrial camera 22, and then the control box 21 controls the motor 2 to adjust the position of the protective component.

[0042] To enable movement of the traveling mechanism 3, it includes a connecting plate 31 and two wheel assemblies 32. Two wheel assemblies 32 are provided, one at each end of the connecting plate 31. Each wheel assembly 32 includes a central shaft 321, a pulley 322, and a gear 324. The central shaft 321 extends through the connecting plate 31 via a bearing connection, while the pulley 322 and gear 324 are respectively mounted on either end of the central shaft 321, thereby ensuring a stable connection between the pulley 322, gear 324, and the connecting plate 31. Furthermore, a first groove 323 is provided on the central shaft 321, while matching protrusions are provided on the walls of the gear 324 and pulley 322. Therefore, the central shaft 321 rotates synchronously with the gear 324 and pulley 322, and the position of the pulley 322 and gear 324 relative to the central shaft 321 is restricted, facilitating stable positioning of the central shaft 321 relative to the guide rail 11 and the handrail. When the motor 2 is installed on the side of the connecting plate 31 through the frame, its power output shaft is connected to the central shaft 321 through a coupling, etc., so that the pulley 322 and the gear 324 can be controlled to rotate under the action of the motor 2.

[0043] A rack 12 is fixedly mounted above the guide rail 11, extending along the length of the rehabilitation ladder 1. A gear 324 and a pulley 322 are mounted on the guide rail 11 and the handrail of the rehabilitation ladder 1, respectively. Gear 324 meshes with rack 12. Therefore, when gear 324 rotates, it controls the movement of the travel mechanism 3 relative to the guide rail 11, enabling the protective assembly to move relative to the rehabilitation ladder 1, providing support for the rehabilitation personnel. Furthermore, an edge is provided at the end of gear 324, similar to that of pulley 322. This arrangement restricts the pulley 322 and gear 324 to movement along the length of the handrail and guide rail 11, preventing the pulley 322 and gear 324 from moving perpendicular to the handrail and guide rail 11.

[0044] To ensure the stable installation of the walking mechanism 3 on the handrail and guide rail 11, a second screw 312 is fixedly mounted below the connecting plate 31. A baffle 313 is sleeved on the second screw 312, and a snap post 314 is fixedly mounted on the side of the baffle 313. A guide plate 13 is also installed on the side of the guide rail 11, positioned between the handrail and the guide rail 11. A snap slot 14 is provided on the guide plate 13. The central angle of the snap slot 14 is greater than 180°, and the snap post 314 is located in the snap slot 14, which restricts the position of the connecting plate 31 relative to the guide rail 11. This ensures the stable installation of the connecting plate 31, pulley 322, and gear 324 relative to the guide rail 11 and the handrail without affecting the movement of the walking mechanism 3.

[0045] In order to achieve the adjustability of the support frame 5, the support frame 5 includes a lifting plate 51 and a bottom tube 52. The bottom of the bottom tube 52 is sleeved on the first screw 311, and the first screw 311 is fixedly set on the connecting plate 31. Therefore, the bottom tube 52 is stably installed on the connecting plate 31, providing support for the stable installation of the support frame 5. The bottom of the lifting plate 51 is fixedly provided with an insert plate, which is inserted into the bottom tube 52 and is provided with multiple connecting holes 511. The bolts set at the top of the bottom tube 52 are passed through one of the connecting holes 511. With the cooperation of the bolts and the connecting holes 511, the lifting plate 51 is stably installed relative to the bottom tube 52, and at the same time, it is convenient to adjust the relative position of the lifting plate 51 and the bottom tube 52 according to needs, thereby adapting to rehabilitation personnel of different heights.

[0046] To ensure timely protection in the event of a fall, the protective mechanism 4 includes a reel assembly 41 and a protective belt 42. The reel assembly 41 comprises a frame 411 and a reel wheel 412. The top shaft of the frame 411 is inserted into the lifting platform 51 via a bearing connection. This allows the frame 411 to rotate when the person turns, facilitating their descent from the rehabilitation ladder 1. The reel wheel 412, which winds a steel wire rope, is located inside the frame 411. The end of a rotating shaft 413 extending through the reel wheel and inserted into the frame 411 ensures that the reel wheel 412 is stably mounted within the frame 411.

[0047] To control the rotation of the take-up wheel 412, a boss 414 is provided on the rotating shaft 413, and a matching structure is provided on the hole wall of the take-up wheel 412. The end of the boss 414 protrudes from the take-up wheel 412, so that the take-up wheel 412 rotates synchronously with the rotating shaft 413. In addition, a limiting plate 416 and a spring 415 are provided on both sides of the take-up wheel 412. The limiting plate 416 is sleeved on the rotating shaft 413, and a structure matching the boss 414 is also provided on the hole wall. Therefore, the limiting plate 416 is arranged in contact with the take-up wheel 412 and covers the boss 414. At this time, the take-up wheel 412 and the limiting plate 416 rotate synchronously or remain stationary. To synchronize the stop plate 416 and the take-up wheel 412, a rod 417 is provided on the side of the stop plate 416 facing away from the take-up wheel 412. This rod 417 extends through the frame 411, ensuring that the stop plate 416 remains stationary relative to the frame 411. When the stop plate 416 covers the boss 414, the take-up wheel 412 stops rotating. A spring 415 is compressed, with its ends contacting the stop plate 416 and the frame 411, respectively. Consequently, the spring 415 maintains a constant tendency for the stop plate 416 to lie against the take-up wheel 412, providing support for controlling the stop plate 416 away from the take-up wheel 412 and allowing the wire rope to be retracted and released. After the stop plate 416 is away from the take-up wheel 412, a rod can be placed between the two stop plates 416. This rod acts to keep the stop plate 416 stationary. Once the rod is removed, the stop plate 416 can be moved to the take-up wheel 412 under the action of the spring 415.

[0048] In order to stably install the protective belt 42 at the bottom of the wire rope, a main plate 421 and a clamping plate 422 are provided at the top of the protective belt 42. The top of the main plate 421 is connected to the wire rope, and a notch is provided at the bottom. A sliding plate 425 is fixedly provided at the top of the notch. The clamping plate 422 is fixed at the notch by bolts, and a sliding groove 424 is provided at the top. The sliding plate 425 is installed in the sliding groove 424, thereby achieving a stable and adjustable connection between the clamping plate 422 and the main plate 421. A perforation 423 is provided on both the clamping plate 422 and the main plate 421. The end of the protective belt 42 is provided through the perforation 423. After the protective belt 42 passes through the perforation 423, the clamping plate 422 and the main plate 421 can be controlled by rotating the bolts to cooperate with each other to clamp the protective belt 42, thereby achieving a stable connection between the protective belt 42, the main plate 421, and the clamping plate 422.

[0049] Example 2

[0050] like Figure 7-10As shown, based on Example 1, in order to be able to brake the protection assembly when the rehabilitation person falls, the height of the connecting hole 511 is greater than the diameter of the bolt, and mutually repelling magnets are provided on the inner side of the bottom tube 52 and the bottom of the lifting plate 51, or a spring is provided in the bottom tube 52. The spring is in a compressed state, and the top contacts the plug plate of the lifting plate 51. Therefore, under the action of the magnet or spring, the bolt penetrates the bottom setting of the connecting hole 511. When the rehabilitation person falls and the protective belt 42 pulls the lifting plate 51 downward relative to the bottom tube 52, the bolt rises relative to the connecting hole 511 and penetrates the top setting of the connecting hole 511.

[0051] The bottom tube 52 is provided with a sliding hole 521 extending along its height. A lug 512 is provided at the bottom of the insert plate, extending through the sliding hole 521. The support frame 5 also includes a brake plate 53. A toothed plate 531 is fixedly mounted on its bottom, and a sleeve 532 is fixedly mounted on its top. The toothed plate 531 is positioned above the gear 324, and the sleeve 532 is sleeved onto the bottom tube 52. An adjusting screw 533 is threadedly threaded through the top of the brake plate 53. The top of the adjusting screw 533 is connected to the lug 512 via a bearing. By rotating the adjusting screw 533, the relative position of the toothed plate 531 and the lifting plate 51 can be adjusted, providing support for the toothed plate 531 to be positioned adjacent to the gear 324. In addition, under the action of the adjusting screw 533, the tooth plate 531 and the lifting plate 51 move synchronously. Therefore, when the lifting plate 51 descends, the tooth plate 531 is controlled to engage with the gear 324, limiting the rotation of the gear 324, and then the walking mechanism 3 is placed stationary relative to the guide rail 11 and the armrest, thereby realizing the protection of the rehabilitation personnel.

[0052] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
