Description

Technical Field

[0001] This invention belongs to the field of rehabilitation equipment technology, and in particular relates to a joint mobility assist component and a rehabilitation device for heatstroke. Background Technology

[0002] During the rehabilitation phase, patients with heatstroke typically need to perform limb joint mobility training. Some patients also experience residual neurological symptoms, requiring simultaneous cognitive training to promote recovery. While there are assistive devices for joint mobility and separate cognitive training tools available on the market, these devices are mostly designed separately. Patients need to switch between different devices to complete limb joint mobility and cognitive training separately, resulting in a less than seamless overall training process.

[0003] Many existing joint mobility aids can only train joints in a single part of the leg or arm, and cannot allow all four limb joints to move simultaneously, resulting in low training efficiency. Furthermore, the labeling components used for cognitive training mostly require medical staff to manually change the labeling content, which is not only cumbersome but also interrupts the training process. Therefore, a joint mobility aid component and a heatstroke rehabilitation device are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a joint mobility assist component and a heatstroke rehabilitation device that can effectively improve the efficiency of joint mobility training for patients, facilitate cognitive training, and is suitable for patients with residual neurological symptoms, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A joint movement assistive component includes: a support shell and a seat mounted on top of the support shell. A first rotating shaft is rotatably connected between the two sides of the support shell. Rotating rods are fixedly connected to both ends of the first rotating shaft. Foot pedals are rotatably connected to one end of each rotating rod. The two foot pedals are arranged vertically for leg joint movement.

[0007] The seat has fixed plates on both sides, and a rocker arm is rotatably connected to one side of each fixed plate for arm joint movement. This enables simultaneous training of the joints of all four limbs without the need for separate operation, making it suitable for rehabilitation scenarios and effectively improving the efficiency of joint movement training for patients.

[0008] Two connecting mechanisms are provided, both of which are located on the bottom inner wall of the support shell to connect the first rotating shaft and the rocker arm;

[0009] A drive assembly is disposed on the bottom inner wall of the support shell for driving the first rotating shaft to rotate.

[0010] Furthermore, the drive assembly includes a motor and a worm gear. The motor is fixed to the bottom inner wall of the support housing, the worm gear is fixed to the circumference of the first rotating shaft, one end of the motor output shaft is fixedly connected to a drive shaft, and one end of the drive shaft is fixedly connected to a worm. The worm rotates with the support housing, and the worm gear is fixed to the circumference of the first rotating shaft and meshes with the worm.

[0011] Furthermore, the connecting mechanism includes a drive disk, a guide rail, and a clearance hole. The drive disk is eccentrically fixed to the circumference of the first rotating shaft. A drive ring is rotatably connected to the circumference of the drive disk. A push-pull rod is rotatably connected to one side of the drive ring. The guide rail is fixed to the bottom inner wall of the support shell. A sliding seat is slidably connected to the top of the guide rail. One end of the push-pull rod is rotatably connected to the sliding seat. A connecting rod is rotatably connected inside the sliding seat. The clearance hole is located on one side of the support shell and is arc-shaped. A first sliding rod is provided inside the clearance hole. A drive rod is fixedly connected between one end of the first sliding rod and the rocker arm. The other end of the first sliding rod is rotatably connected to the connecting rod.

[0012] The present invention also proposes a heatstroke rehabilitation device, including a joint movement assist component and a fixing sleeve fixed to the top of the support shell. The top of the fixing sleeve is fixedly connected to a mounting shell. One side of the mounting shell is open and the other side is rotatably connected to a through second rotating shaft. One end of the second rotating shaft is fixed with a label plate by bolts.

[0013] Furthermore, a cover is threadedly connected to the open side of the mounting shell, and an observation port is provided on one side of the cover.

[0014] Furthermore, a second slide rod is slidably connected inside the fixed sleeve, and a rack is fixedly connected to the top of the second slide rod. An overrunning clutch is fixedly sleeved at one end of the second rotating shaft, and a gear is fixedly installed on the outer wall of the overrunning clutch. The gear meshes with the rack. An eccentric wheel is fixedly connected to the circumference of the first rotating shaft, and the eccentric wheel abuts against the bottom of the second slide rod. A vertical guide hole is opened on one side of the fixed sleeve, and a guide block is fixedly connected to one side of the second slide rod. A tension spring is installed between the guide block and the top of the support shell through a hook. Through the cooperation of the eccentric wheel, the second slide rod, and the overrunning clutch, when the first rotating shaft rotates, it drives the eccentric wheel to push the second slide rod. Through rack and gear transmission, the signboard automatically changes the displayed sign. The overrunning clutch prevents the signboard from reversing, eliminating the need for manual adjustment, facilitating cognitive training, and is suitable for patients with residual neurological symptoms.

[0015] Furthermore, a protective box is fixedly connected to one side of the mounting housing, with gears and racks meshing together.

[0016] Furthermore, support legs are fixedly connected to both sides of the support shell.

[0017] The embodiments of the present invention have the following beneficial effects:

[0018] In this invention, by using a motor, worm gear and connecting mechanism in combination, when the motor drives the first rotating shaft to move the foot pedal to move the leg joint, it can also drive the rocker arm to swing through the drive plate, push-pull rod and other means to achieve synchronous training of the joints of the limbs. No separate operation is required, which is suitable for rehabilitation scenarios and effectively improves the efficiency of joint movement training for patients.

[0019] In this invention, the eccentric wheel, the second slide bar, and the overrunning clutch work together to drive the eccentric wheel to push the second slide bar when the first shaft rotates. Through rack and pinion transmission, the signboard automatically changes the displayed sign. The overrunning clutch prevents the signboard from reversing, eliminating the need for manual adjustment, facilitating cognitive training, and making it suitable for patients with residual neurological symptoms.

[0020] In this invention, a shell cover connected by threads and a sign plate fixed by bolts are used together. After unscrewing the shell cover and removing the fixing bolts, the sign plate can be removed to replace different cognitive training content (such as numbers, letters, and graphics), which can meet the needs of different patients or different training stages and improve the adaptability of the device to cognitive rehabilitation training.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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.

[0031] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] In one embodiment, please refer to Figures 1-6 As shown, this embodiment provides a joint mobility assistive component, including: a support shell 1, on which a seat 2 is mounted by bolts or welding. The seat cushion of the seat 2 is made of elastic sponge material and covered with breathable fabric to improve patient comfort and facilitate prolonged joint mobility training. Axle holes are provided on both sides of the support shell 1, and a first rotating shaft 7, passing through the entire support shell 1, is rotatably connected to the shaft holes via bearings. Rotating rods 10 are fixedly connected to both ends of the first rotating shaft 7. A foot pedal 11 is rotatably connected to the end of the rotating rod 10 away from the first rotating shaft 7. The two foot pedals 11 are initially staggered vertically, allowing the patient's feet to alternately rise and fall as the rotating rods 10 rotate, thus meeting the needs of leg joint movement.

[0033] Both sides of the outer wall of the seat 2 are fixedly connected to the fixing plate 20 by screws. The fixing plate 20 is set perpendicular to the side of the seat 2. Each fixing plate 20 is rotatably connected to the rocker arm 3 on the side away from the seat 2. The rocker arm 3 is covered with a non-slip rubber sleeve. The surface of the rubber sleeve has a non-slip texture, which makes it convenient for the patient to hold the two rocker arms 3 with both hands and move the arm joint by swinging the rocker arm 3.

[0034] In another embodiment: refer to Appendix Figures 1-6A joint movement assist component includes two connecting mechanisms mounted on the bottom inner wall of a support shell 1. These mechanisms correspond to rocker arms 3 on either side, facilitating power transmission between a first rotating shaft 7 and the rocker arms 3. A drive disc 12 in each connecting mechanism is eccentrically fixed to the circumference of the first rotating shaft 7 via a key connection. The center of the drive disc 12 does not coincide with the axis of the first rotating shaft 7, forming an eccentric structure. A drive ring 13 is rotatably connected to the outer circumference of the drive disc 12. A push-pull rod 14 is rotatably connected to one side of the drive ring 13 via a pin. The push-pull rod 14 is made of metal and has holes at both ends for connection. A guide rail 15 is bolted to the bottom inner wall of the support shell 1. The guide rail 15 is horizontally positioned, and a sliding seat 16 is slidably connected to its top. The bottom of the sliding seat 16 has a groove matching the guide rail 15, ensuring stable sliding along the guide rail 15. The end of the push-pull rod 14 away from the drive ring 13 is rotatably connected to the sliding seat 16 via a pin. The top of the sliding seat 16 is rotatably connected to the connecting rod 18 via a bearing. The support shell 1 has a clearance hole 17 on the side corresponding to the connecting rod 18. The clearance hole 17 is arc-shaped, and its curvature matches the swing trajectory of the rocker arm 3, providing space for the movement of subsequent components. A first slide rod 19 passes through the clearance hole 17. The first slide rod 19 can slide along the arc trajectory of the clearance hole 17. The end of the first slide rod 19 near the rocker arm 3 is fixedly connected to the rocker arm 3 by welding or bolts to a drive rod 21. The drive rod 21 is fixed to the rocker arm 3. The end of the first slide rod 19 away from the rocker arm 3 is rotatably connected to the connecting rod 18 via a pin.

[0035] A drive assembly is also installed on the bottom inner wall of the support housing 1 to drive the first rotating shaft 7 to rotate. The motor 5 in the drive assembly is fixed to the bottom inner wall of the support housing 1 by a motor mount. The worm gear 8 is fixed at the center of the circumference of the first rotating shaft 7 by a key connection. One end of the output shaft of the motor 5 is fixedly connected to the drive shaft 6 by a coupling. The end of the drive shaft 6 away from the motor 5 is fixedly connected to the worm 9. The end of the worm 9 away from the drive shaft 6 is rotatably connected to the inner wall of the support housing 1 by a bearing, ensuring that the worm 9 can rotate stably. The worm 9 and the worm gear 8 mesh with each other. This structure has a self-locking function, which can prevent the first rotating shaft 7 from rotating in the opposite direction when the motor 5 stops working, thus improving the safety of use.

[0036] The present invention also proposes a heatstroke rehabilitation device comprising the aforementioned joint mobility assistive components, and further comprising a fixing sleeve 4 fixed to the top of the support shell 1. The fixing sleeve 4 is a vertical cylindrical structure, and a mounting shell 22 is fixedly connected to its top. The mounting shell 22 is a hollow rectangular shell structure. One side of the mounting shell 22 is an open design, and a second rotating shaft 23 is rotatably connected to the side wall of the other side via a bearing. One end of the second rotating shaft 23 located inside the mounting shell 22 is fixed with a label plate 24 by bolts. The surface of the label plate 24 is printed with labels for cognitive training, such as numbers, letters, or graphics. During training, patients can view the labels on the label plate 24 to conduct cognitive training, which is convenient for patients with residual neurological symptoms to use.

[0037] The open side of the housing 22 is connected to the cover 25 by threads. An observation port 26 is provided on one side of the cover 25. A transparent acrylic plate or glass can be embedded in the observation port 26, so that the patient can see the markings on the label 24 through the observation port 26 without opening the cover 25, while also protecting the label 24.

[0038] A second slide rod 31 is slidably connected inside the fixed sleeve 4. The second slide rod 31 is vertically arranged and can slide up and down along the inner wall of the fixed sleeve 4. A rack 29 is fixedly connected to the top of the second slide rod 31 by welding. The rack 29 is vertically arranged. An overrunning clutch 27 is fixedly sleeved at one end of the second rotating shaft 23 outside the mounting shell 22. A gear 28 is fixedly installed on the outer wall of the overrunning clutch 27. The gear 28 meshes with the rack 29. An eccentric wheel 34 is fixedly connected to the circumference of the first rotating shaft 7 by a key. The outer circumference of the eccentric wheel 34 abuts against the bottom of the second slide rod 31. When the eccentric wheel 34 rotates, its protruding part can push the second slide rod 31 upward. A vertical guide hole is provided on one side of the fixed sleeve 4, which penetrates the side wall of the fixed sleeve 4. A guide block 32 is fixedly connected to one side of the second slide rod 31 by bolts. The guide block 32 extends through the guide hole to the outside of the fixed sleeve 4 and can slide up and down along the guide hole, thus guiding the second slide rod 31 and preventing it from rotating during sliding. A tension spring 33 is installed between the guide block 32 and the top of the support shell 1 through a hook. When the protruding part of the eccentric wheel 34 leaves the bottom of the second slide rod 31, the tension spring 33 can pull the guide block 32 downward, thereby driving the second slide rod 31 to return to its original position.

[0039] A protective box 30 is fixedly connected to one side of the mounting shell 22 by bolts. The protective box 30 covers the meshing part of the gear 28 and the rack 29 to prevent external dust and debris from entering the meshing part and affecting the transmission. It can also prevent patients from accidentally touching the moving parts and causing injury during use.

[0040] Both sides of the support shell 1 are fixedly connected to support legs by welding or bolts. The bottom of the support legs is equipped with anti-slip pads, which can increase the friction with the ground and ensure that the entire heatstroke rehabilitation device is more stable when placed on the ground, avoiding shaking or tipping during use and improving safety.

[0041] The usage process and working principle of the technical solution of this invention are as follows:

[0042] When using it, sit on the seat 2, hold the two rocker arms 3 with both hands, place your feet on the two foot pedals 11, start the motor 5, the motor 5 drives the worm gear 9 to rotate through the drive shaft 6, the worm gear 9 drives the first rotating shaft 7 to rotate through the worm wheel 8, and then drives the two rotating rods 10 to rotate. The rotating rods 10 drive the patient's legs to move through the foot pedals 11, thereby achieving the purpose of moving the leg joints.

[0043] During the rotation of the first rotating shaft 7, the drive disk 12 is also driven to rotate. The drive disk 12 is eccentrically installed, so that the drive ring 13 on its outer periphery drives the push-pull rod 14 to reciprocate. The push-pull rod 14 moves the sliding seat 16. The sliding seat 16 pushes and pulls the first sliding rod 19 through the connecting rod 18. The first sliding rod 19 drives the rocker arm 3 to swing through the drive rod 21, thereby moving the joints on the arm.

[0044] During training, the markings on the label plate 24 can be viewed, which can then be used for cognitive training, making it convenient for those with residual neurological symptoms. When the first rotating shaft 7 rotates, it also drives the eccentric wheel 34 to rotate. The eccentric wheel 34 can lift the second slide rod 31 upwards. The second slide rod 31 drives the rack 29 to rotate. The rack 29 drives the second rotating shaft 23 to rotate through the gear 28 and the overrunning clutch 27. The second rotating shaft 23 drives the label plate 24 to rotate, thereby changing the markings exposed on the label plate 24, avoiding manual replacement and improving the automation of the equipment. The second slide rod 31 can be reset by the tension spring 33. Under the action of the overrunning clutch 27, the second rotating shaft 23 is prevented from reversing. The label plate 24 can be replaced after removing the cover 25, making it flexible to use.
