Description

Technical Field

[0001] The 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 method used to help patients with functional disorders caused by injuries or diseases of the bones, muscles, joints, ligaments, tendons and other locomotor systems to restore their body functions. Because during illness or injury, the muscles in the affected area often atrophy and weaken due to long-term 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, passive joint mobility training is required for patients with severe conditions who are unable to actively move their joints in the early stages. When the condition has improved and they have a certain degree of autonomous mobility, active joint mobility training will be carried out. In the later stages of rehabilitation, patients will receive relatively difficult training, such as stair climbing training. Patients need to learn the correct stair climbing posture and skills, such as taking the healthy leg first when going upstairs and taking 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] In order to assist medical staff and patients in completing rehabilitation training, many orthopedic training auxiliary devices have appeared on the market, such as CPM machines, joint range of motion trainers, elastic bands, isokinetic muscle training devices, balance boards, gait training belts, etc. The above-mentioned various devices are mainly used for joint range of motion training, muscle strength training, balance ability training, etc., while auxiliary devices for stair climbing and descending training are almost non-existent.

[0005] At present, the method used for patients to go up and down stairs is that the patients are protected by staff in rehabilitation training centers or residential areas and complete the training on the stairs of the building. This training method has some defects. For example, because the lower limb muscle strength of patients is often weak, they may not be able to support the body well to complete the movements of going up and down stairs; their balance ability is also poor, and they are prone to lose balance and fall in the process of going up and down stairs. Therefore, staff are needed to support and assist them to complete the task of going up and down stairs training, which makes it impossible for the assisting personnel to perform other tasks and the cost is high. In addition, the stairs attached to the building are limited. If there are many people undergoing orthopedic rehabilitation training, the number of people assisting in the rehabilitation training is insufficient, and it is impossible to meet the needs of multiple people to go up and down stairs training at the same time, which affects the progress of rehabilitation training tasks.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to 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 stair climbing and descending rehabilitation training needs of multiple rehabilitation personnel and reduce the care time of staff for a single rehabilitation personnel, this embodiment provides an auxiliary device for stair climbing and descending training. Multiple sets of the auxiliary device can be set up in a rehabilitation training center. Rehabilitation personnel can complete stair climbing and descending training on the auxiliary device, and at the same time provide protection for the 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 protection component. A bracket is installed below the rehabilitation ladder 1. Under the action of the bracket, the rehabilitation ladder 1 is stably set in the rehabilitation center, and the rehabilitation ladder 1 can be moved by pulling the bracket to adjust its position. The protection component is set on the handrail of the rehabilitation ladder 1 and can be raised and lowered along the handrail of the rehabilitation ladder 1. Therefore, the protection component can adjust its position relative to the rehabilitation ladder 1 as the rehabilitation personnel rise and fall, so as to provide full protection for the rehabilitation personnel.

[0040] In order to stably install the protection component 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 provided along the inclination direction of the rehabilitation ladder 1. The protection component is arranged across the handrail of the rehabilitation ladder 1 and the guide rail 11 to increase the walking stability of the protection component.

[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 it can control the movement of the walking mechanism 3 by 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 avoid the existence of the walking mechanism 3 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 provided 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 personnel through the industrial camera 22, and then the control box 21 controls the motor 2 to adjust the position of the protection component.

[0042] In order to realize the movement of the walking mechanism 3, the walking mechanism 3 includes a connecting plate 31 and a wheel set 32. The wheel set 32 ​​is provided with two sets, and is respectively provided at both ends of the connecting plate 31. Each wheel set 32 ​​includes a central shaft 321, a pulley 322 and a gear 324. The central shaft 321 is connected through the connecting plate 31 through a bearing, and the pulley 322 and the gear 324 are respectively sleeved at both ends of the central shaft 321, so that the pulley 322, the gear 324 and the connecting plate 31 are stably connected. At the same time, a first groove 323 is provided on the central shaft 321, and a convex rod matching with it is provided on the hole wall of the gear 324 and the pulley 322, so that the central shaft 321 rotates synchronously with the gear 324 and the pulley 322, and the position of the pulley 322 and the gear 324 relative to the central shaft 321 is limited, which provides convenience for controlling the stable placement 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 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 arranged above the guide rail 11, and the rack 12 is arranged along the length direction of the rehabilitation ladder 1. The gear 324 and the pulley 322 are respectively arranged on the guide rail 11 and the handrail of the rehabilitation ladder 1, and the gear 324 is meshed and connected with the rack 12. Therefore, when the gear 324 rotates, the walking mechanism 3 can be controlled to move relative to the guide rail 11, so that the protection component can move relative to the rehabilitation ladder 1, providing support for the protection of the rehabilitation personnel. In addition, an edge is arranged at the end of the gear 324, similar to the pulley 322. This arrangement allows the pulley 322 and the gear 324 to move only along the length direction of the handrail and the guide rail 11, that is, to prevent the pulley 322 and the gear 324 from deviating from the vertical handrail and the guide rail 11.

[0044] In order to stably install the walking mechanism 3 on the handrail and the guide rail 11, a second screw rod 312 is fixedly installed below the connecting plate 31, a baffle plate 313 is sleeved on the second screw rod 312, and a buckle column 314 is fixedly installed on the side of the baffle plate 313. At the same time, a guide plate 13 is installed on the side of the guide rail 11, the guide plate 13 is located between the handrail and the guide rail 11, and a buckle groove 14 is provided on the guide plate 13, the central angle of the buckle groove 14 is greater than 180°, and the buckle column 314 is located in the buckle groove 14, which limits the position of the connecting plate 31 relative to the guide rail 11, so that the connecting plate 31, the pulley 322 and the gear 324 can be stably installed relative to the guide rail 11 and the handrail, and the movement of the walking mechanism 3 is not affected.

[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 to provide support for the stable installation of the support frame 5. A plug plate is fixedly set at the bottom of the lifting plate 51. The plug plate is inserted into the bottom tube 52 and is provided with a plurality of connecting holes 511. The bolts set at the top of the bottom tube 52 are set through a certain connecting hole 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 it is convenient to adjust the relative position of the lifting plate 51 and the bottom tube 52 according to needs, so as to adapt to rehabilitation personnel of different heights.

[0046] In order to take protective measures in time when the rehabilitation personnel fall, the protection mechanism 4 includes a winding group 41 and a protection belt 42. The winding group 41 includes a frame 411 and a winding wheel 412. The top shaft of the frame 411 is connected and inserted into the lifting plate 51 through a bearing connection. Therefore, it is convenient to drive the frame 411 to rotate when the rehabilitation personnel turn around, providing convenience for the rehabilitation personnel to descend from the rehabilitation ladder 1. The winding wheel 412 is wound with a steel wire rope and is arranged on the inner side of the frame 411. At the same time, the end of the rotating shaft 413 arranged therethrough is inserted into the frame 411. Therefore, under the action of the rotating shaft 413, the winding wheel 412 is stably installed in the frame 411.

[0047] In order to control the rotation of the winding wheel 412, a boss 414 is provided on the rotating shaft 413, and a matching structure is provided on the hole wall of the winding wheel 412, and the end of the boss 414 protrudes from the winding wheel 412, so that the winding 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 winding wheel 412, and 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, so that the limiting plate 416 is arranged in close contact with the winding wheel 412 and shields the boss 414 at the same time, and at this time, the winding wheel 412 and the limiting plate 416 rotate synchronously or stand still. In order to control the limiting plate 416 and the winding wheel 412 to be synchronously stationary, a plug rod 417 is provided on the side of the limiting plate 416 away from the winding wheel 412, and the plug rod 417 is provided through the frame 411, so that the limiting plate 416 is placed stationary relative to the frame 411, and when the limiting plate 416 covers the protruding column 414, the winding wheel 412 stops rotating. The spring 415 is in a compressed state, and its two ends are respectively in contact with the limiting plate 416 and the frame 411, so that under the action of the spring 415, the limiting plate 416 always has a tendency to be placed in contact with the winding wheel 412, and at the same time, it provides support for controlling the limiting plate 416 away from the winding wheel 412 to realize the retraction and release of the wire rope. After the limiting plate 416 is away from the winding wheel 412, a rod body can be placed in front of the two limiting plates 416, and the limiting plate 416 is made stationary by the action of the rod body. After the rod body is removed, the limiting plate 416 can be moved to the winding 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 board 421 and a clamping plate 422 are arranged at the top of the protective belt 42. The top of the main board 421 is connected to the wire rope, and a notch is arranged at the bottom. A sliding plate 425 is fixedly arranged at the top of the notch. The clamping plate 422 is arranged at the notch by bolt connection, and a sliding groove 424 is arranged at the top. The sliding plate 425 is installed in the sliding groove 424 to achieve a stable and adjustable connection between the clamping plate 422 and the main board 421. A perforation 423 is arranged on the clamping plate 422 and the main board 421. The end of the protective belt 42 is arranged to pass through the perforation 423. After the protective belt 42 passes through the perforation 423, the clamping plate 422 and the main board 421 can be controlled by rotating the bolt to cooperate with the clamping plate 421 to clamp the protective belt 42, so as to achieve a stable connection between the protective belt 42 and the main board 421 and the clamping plate 422.
