Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing technology, and in particular to a joint rehabilitation device. Background Technology
[0002] With the increasing aging of society and the frequent occurrence of various accidents and sports injuries, the number of patients with elbow joint injuries is showing a significant upward trend. As one of the important joints of the upper limb, the integrity of the elbow joint's function has a crucial impact on daily living self-care ability (such as eating, dressing, washing, etc.) and occupational activities (such as manual labor, tool handling, etc.). In the rehabilitation treatment of elbow joint injuries, traditional rehabilitation methods mainly rely on manual assisted training by rehabilitation therapists and some simple rehabilitation equipment, such as elastic bands and hand grippers. However, these traditional methods have many limitations. Although manual assisted training by rehabilitation therapists can provide personalized rehabilitation guidance according to the specific situation of patients, it is limited by human resources and cannot provide long-term, high-frequency rehabilitation training services for every patient, making it difficult to meet the needs of comprehensive rehabilitation. Therefore, we have launched a joint rehabilitation device. Utility Model Content
[0003] The main purpose of this invention is to provide a joint rehabilitation device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The main device includes a drive motor, the output end of which passes through a fixed plate and is fixedly connected to a main gear. A connecting rod is fixedly connected to the front end of the main gear. A bending component is meshed with the upper part of the outer surface of the main gear. A component is fixedly connected between the middle of the front end and the middle of the rear end of the bending component. Two components are fixedly connected between the right front end and the right rear end of the bending component. The drive motor is fixedly connected to the upper rear end of the fixed plate.
[0007] Preferably, the bending assembly includes a connecting rod, a driven gear is fixedly connected to the middle of the outer surface of the connecting rod, a connecting plate is fixedly connected to both the front and rear of the outer surface of the driven gear, a stabilizing plate is fixedly connected between the left front and left rear of the two connecting plates, a sponge pad is fixedly connected to the surface of the stabilizing plate, and the connecting rod is located above the base device.
[0008] By adopting the above technical solution: the No. 1 sponge pad is fixed on the surface of the stabilizing board. During rehabilitation training, when the user's limbs come into contact with the bending components, the sponge pad can play a buffering role, avoiding discomfort or injury caused by direct collision between the limbs and hard parts, and providing users with a more comfortable rehabilitation experience.
[0009] Preferably, the placement component includes a support plate, a second sponge pad is fixedly connected to the upper middle part of the support plate, screw holes are opened at both the front and rear ends of the support plate, and bolts are threaded into the two screw holes respectively. A first female hook and loop fastener and a first male hook and loop fastener are fixedly connected to the upper front and upper rear parts of the support plate respectively. The support plate is fixedly connected between the front middle and rear middle parts of the two connecting plates by bolt threads.
[0010] By adopting the above technical solution, the design of screw holes and bolts enables a threaded connection between the support plate and the connecting plate.

Furthermore, the position of the support plate can be flexibly adjusted according to the size of the user's limb and the specific needs of rehabilitation training to achieve the best rehabilitation training effect.
[0011] Preferably, the placement component includes a placement plate, with a No. 2 female hook and loop fastener and a No. 2 male hook and loop fastener respectively fixedly connected to the upper front and upper rear parts of the placement plate, and a No. 3 sponge pad fixedly connected to the surface of the placement plate. The placement plate is fixedly connected to the upper right part of the base device.
[0012] By adopting the above technical solution: the No. 3 sponge pad is fixed on the surface of the placement board.

[0016] By adopting the above technical solution: the meshing of the driven gear and the main gear is the key link in the power transmission of the entire device. The rotational motion of the main gear is transmitted to the connecting rod through the meshing with the driven gear, causing the connecting rod to rotate around the axis, thereby converting the rotational power of the motor into a bending motion form suitable for elbow joint rehabilitation, providing a power basis for the subsequent movement of the placement components.
[0017] Preferably, the outer surface of the first female hook and loop fastener is bonded to the inner surface of the first male hook and loop fastener, and the position and size of the two screw holes are adapted to the position and size of the two bolts.
[0018] By adopting the above technical solution: the No. 1 female hook and loop fastener and the No. 1 male hook and loop fastener are located at the upper front and rear of the support plate, respectively. They can be glued together to fix the user's limbs. During rehabilitation training, this fixation method can effectively prevent the limbs from slipping due to the movement of the device, ensure the stability of the limbs on the support plate, and make the rehabilitation training movements more accurate and effective.
[0019] Preferably, the rear end of the connecting rod is movably connected to the right side of the front seat wall of the base device via a bearing, and the bottom of the main gear does not contact the base device.
[0020] By adopting the above technical solution, the bottom of the main gear does not contact the base equipment, which can prevent the main gear from rubbing or colliding with the base equipment during rotation, and avoid problems such as power loss, motion jamming or component damage caused by these interference factors.

[0034] Please see Figure 1-6 This utility model provides a technical solution:
[0035] A joint rehabilitation device includes a base device 1, a processor 5 is provided at the middle of the front end of the base device 1, a handle 2 is fixedly connected to the right front end and the right rear end of the base device 1, a main body device 6 is fixedly connected to the right upper end of the base device 1, a connecting line 4 is provided at the left end of the base device 1, a remote control 3 is fixedly connected to the other end of the connecting line 4, a groove 7 is opened at the right upper end of the base device 1, and a fixing plate 8 is fixedly connected to the rear of the lower groove wall of the groove 7.
[0036] In this embodiment, the main device 6 includes a drive motor 61. The output end of the drive motor 61 passes through the fixed plate 8 and is fixedly connected to a main gear 62. A connecting rod 63 is fixedly connected to the front end of the main gear 62. A bending component 64 is meshed with the upper part of the outer surface of the main gear 62. A component 65 is fixedly connected between the middle of the front end and the middle of the rear end of the bending component 64. A second component 66 is fixedly connected between the right side of the front end and the right side of the rear end of the bending component 64. The drive motor 61 is fixedly connected to the upper part of the rear end of the fixed plate 8. The bending component 64 includes a connecting rod 642. A driven gear 641 is fixedly connected to the middle of the outer surface of the connecting rod 642. Connecting plates 643 are fixedly connected to both the front and rear parts of the outer surface. A stabilizing plate 644 is fixedly connected between the left front and left rear parts of the two connecting plates 643. A sponge pad 645 is fixedly connected to the surface of the stabilizing plate 644. The connecting rod 642 is located above the base device 1. The position and size of several through holes 646 are adapted to the position and size of two bolts 653. The gear 641 is meshed and connected to the upper part of the outer surface of the main gear 62. The two connecting plates 643 are located on the front and rear sides of the placement plate 661, respectively. The rear end of the connecting rod 63 is movably connected to the right side of the front seat wall of the base device 1 through a bearing. The bottom of the main gear 62 does not contact the base device 1.
[0037] Through the above scheme: the drive motor 61 starts under the control signal of the connected processor 5, and its output end drives the main gear 62 to rotate through the fixed plate 8. The connecting rod 63 at the front end of the main gear 62 is movably connected to the right side of the front seat wall of the base device 1 through the bearing, ensuring the stability of the rotation and preventing the bottom of the main gear 62 from contacting the base device 1 to avoid friction interference. The rotation of the main gear 62 is transmitted to the bending component 64 that meshes with it, thereby driving the entire rehabilitation action, so that the first component 65 and the second component 66 move according to the set trajectory, simulating the flexion and extension of the elbow joint, accurately controlling the rehabilitation action, adapting to the requirements of different rehabilitation stages for the flexion and extension force, speed and range of the elbow joint, providing diversified training modes for elbow joint rehabilitation, and effectively promoting the recovery of elbow joint function. From the meshing transmission between the gear 641 and the main gear 62, the connecting rod 6 42 rotates around its own axis, and the connecting plate 643 fixed to the front and rear of the gear 641 on the connecting rod 642 moves accordingly, driving the stabilizing plate 644 and the first sponge pad 645 connected between the front left and rear left of the connecting plate 643 to change position. The two connecting plates 643 are located on the front and rear sides of the placement plate 661, respectively. Through the connection with the placement component 65, the rotational motion is converted into a curved motion suitable for elbow flexion and extension. Several through holes 646 cooperate with the bolts 653 in the placement component 65 to ensure a stable connection and coordinated movement. The rotational power of the drive motor 61 is converted into a bending motion that conforms to the physiological movement curve of the elbow joint, ensuring the scientific and effective nature of rehabilitation training. The first sponge pad 645 effectively prevents collision damage to the skin and tissues around the elbow joint during exercise, improving the safety and comfort of training.
[0038] In this embodiment, the placement component 65 includes a support plate 651. A second sponge pad 656 is fixedly connected to the upper middle part of the support plate 651. Screw holes 652 are opened at both the front and rear ends of the support plate 651, and bolts 653 are threaded into the two screw holes 652 respectively. A first female Velcro 654 and a first male Velcro 655 are fixedly connected to the upper front and upper rear parts of the support plate 651 respectively. The support plate 651 is threadedly fixed between the front middle and rear middle parts of the two connecting plates 643 by bolts 653. The placement component 66 includes a placement plate 661, which is used for placement... The upper front and upper rear parts of plate 661 are respectively fixedly connected with a No. 2 female hook and loop fastener 662 and a No. 2 male hook and loop fastener 663. A No. 3 sponge pad 664 is fixedly connected to the surface of plate 661. Plate 661 is fixedly connected to the upper right part of base device 1. The surface of plate 661 has a slope-shaped structure. The outer surface of the No. 2 female hook and loop fastener 662 is bonded to the inner surface of the No. 2 male hook and loop fastener 663. The outer surface of the No. 1 female hook and loop fastener 654 is bonded to the inner surface of the No. 1 male hook and loop fastener 655. The position and size of the two screw holes 652 are adapted to the position and size of the two bolts 653.
[0039] Through the above scheme: the support plate 651 is threadedly fixed to the connecting plate 643 of the bending component 64 using bolts 653 passing through the threaded hole 652. The fixed position can be adjusted according to the size of the user's elbow joint and rehabilitation needs. The second sponge pad 656 in the middle of the upper end of the support plate 651 contacts the user's forearm. Under the action of the bending component 64, the support plate 651 moves, causing the forearm to follow the flexion and extension movements. At the same time, the first female Velcro 654 and the first male Velcro 655 are attached and fixed to the forearm to prevent slippage during movement, providing a stable and reliable placement and fixation platform for the forearm during elbow joint rehabilitation training. The second sponge pad 656 reduces pressure on the forearm and avoids local pressure discomfort. The Velcro design allows for convenient and quick fixation and release of the forearm, facilitating adjustment and rest for the patient during training, improving the convenience and flexibility of rehabilitation training. The placement plate 661 is fixed. On the upper right side of the base device 1, its surface has a sloping structure. When the bending component 64 is working, the placement plate 661 works in conjunction with other components, allowing the user's upper arm to be placed on the placement plate 661. The upper arm is secured by the second female Velcro 662 and the second male Velcro 663. During rehabilitation training, the relative movement between the placement plate 661 and the placement component 65 guides the elbow joint to flex and extend. The third sponge pad 664 on its surface provides contact protection and provides comfortable and stable support for the upper arm. Its sloping structure conforms to the movement trajectory of the upper arm during elbow flexion and extension, which helps guide correct rehabilitation movements. The third sponge pad 664 protects the upper arm skin from friction and pressure, and the Velcro fixation ensures the upper arm is in a stable position during training. Together with the placement component 65, it comprehensively ensures the smooth progress of elbow joint rehabilitation training and improves rehabilitation effects.
[0040] It should be noted that this utility model is a joint rehabilitation device. During use, the user first issues a command via remote control 3. The signal is transmitted via connecting cable 4 to the connecting processor 5 at the front center of the base device 1 for processing. Subsequently, the drive motor 61 installed on the upper rear end of the fixed plate 8 starts, and its output end passes through the fixed plate 8 to drive the main gear 62 to rotate. The rear end of the connecting rod 63 at the front end of the main gear 62 is movably connected to the right side of the front seat wall of the base device 1 through a bearing, and its bottom does not contact the base device 1. When the main gear 62 rotates, the bending component 64 meshing with the upper part of its outer surface begins to operate. The driven gear 641 in the middle of the outer surface of the connecting rod 642 in the bending component 64 rotates with the main gear 62, driving the connecting rod 642 to rotate. The connecting plate 643, which is fixedly connected to both the front and rear of the outer surface of the driven gear 641, also moves accordingly. The first sponge pad 645 on the surface of the stabilizing plate 644 located between the left front end and the left rear end of the connecting plate 643 moves accordingly. As the position changes, the component 65, fixed between the middle of the front end and the middle of the rear end of the two connecting plates 643, also moves in coordination. The support plate 651 is connected to the connecting plate 643 by bolts 653. The bolts 653 are threaded into the screw holes 652 of the support plate 651. The second sponge pad 656 at the middle of the upper end of the support plate 651 contacts the user's forearm. The first female Velcro 654 and the first male Velcro 655 at the front and rear of the upper end are bonded to fix the forearm, so that the forearm moves with the component 65. At the same time, the second component 66, fixed to the upper right side of the base device 1, participates in the movement. The surface of the placement plate 661 has a slope-shaped structure. The second female Velcro 662 and the second male Velcro 663 at the front and rear of the upper end are bonded to fix the user's upper arm. The third sponge pad 664 on the surface provides protection. When the first component 65 moves, the second component 66 works in coordination to guide the elbow joint to perform flexion and extension rehabilitation exercises, thereby achieving the rehabilitation and rehabilitation effect on the elbow joint.
