Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation technology, and in particular to a limb movement rehabilitation device. Background Technology

[0002] With the increasing demand for health and rehabilitation in society, sports rehabilitation, as an emerging interdisciplinary field, is receiving more and more attention. It combines knowledge from sports science, medicine, and health science to provide patients with personalized rehabilitation plans. Publication number CN209864521U discloses a limb movement rehabilitation device, relating to the field of medical rehabilitation technology. This utility model relates to the field of medical rehabilitation technology, specifically disclosing a limb movement rehabilitation device, including a base plate and a support rod. The support rod is fixed to the upper surface of the base plate, and the upper surface of the base plate has a sliding groove. A seat is provided above the sliding groove, and the seat is installed in the sliding groove through a height adjustment mechanism. A support plate is fixed to the inner side of the support rod. An upper limb rehabilitation mechanism is provided above the support plate, and a lower limb rehabilitation mechanism is provided below the support plate. The lower limb rehabilitation mechanism includes an L-shaped mounting frame, which is fixed to the upper surface of the base plate. The bottom end of the mounting frame has a driving wheel, and the upper end of the mounting frame has a driven wheel. The driving wheel and the driven wheel are connected by a synchronous belt, and a crank foot pedal is provided on the driven wheel. This invention combines an upper limb rehabilitation mechanism with a lower limb rehabilitation mechanism, allowing patients to perform rehabilitation exercises for both upper and lower limbs simultaneously simply by sitting in the chair. This makes it more practical and applicable to a wider range of situations. However, this device does not consider the differences in height, leg and arm length among patients. Since patients vary in height, the inability to adjust the angle and height will make it difficult to meet the needs of individual patients, changes in rehabilitation stages, and the requirements of multiple programs and environments. This can easily lead to discomfort during rehabilitation training, limited effectiveness, and poor versatility. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a limb movement rehabilitation device, including a base plate, a base fixedly installed on the surface of the base plate, a threaded block fixedly installed inside the base, a double screw threadedly connected inside the threaded block, a top block fixedly installed on the surface of the double screw, a bevel gear rotating handle rotatably connected inside the top block, a seat fixedly installed at the top of the top block, a sliding groove opened on the surface of the base plate, an electric telescopic rod fixedly installed inside the sliding groove, a slide seat fixedly installed at the output end of the electric telescopic rod, a movement frame rotatably connected inside the slide seat, a motor fixedly installed on one side of the movement frame, a frame plate fixedly installed at the bottom end of the motor, a foot rotating rod rotatably connected inside the movement frame, a pedal rotatably connected at one end of the foot rotating rod, and a hand rotating rod rotatably connected at one end of the movement frame.

[0005] Preferably, the top end of the twin screw meshes with one end of the bevel gear handle, and the surface of the top block is slidably connected to the inner wall of the base. Here, the meshing of the bevel gear handle with the twin screw causes the top block, which is fixedly mounted on the surface of the twin screw, to rise and fall together, thereby achieving the function of raising and lowering the base.

[0006] Preferably, the bottom end of the slide block is slidably connected to the interior of the slide groove, and one end of the frame plate is fixedly connected to one side of the base. Here, the sliding between the slide block and the slide groove allows the distance between the slide block and the seat to be freely adjusted.

[0007] Preferably, the bottom end of the seat is slidably connected to the top end of the base, and the pedals are symmetrically arranged at both ends of the foot lever. Here, the base supports the seat, and the pedals provide greater stability for the patient when performing foot lever movements.

[0008] Preferably, a fixing plate is fixedly installed on one side of the exercise frame, a limiting block is fixedly installed on the surface of the fixing plate, a tension spring is slidably connected to the surface of the limiting block, and a tension plate is fixedly installed at one end of the tension spring. Here, the connection between the tension spring and the limiting plate allows the patient to perform upper limb strength exercises.

[0009] Preferably, one end of the tension spring is fixedly connected to one side of the fixed plate, and the tension spring is evenly distributed on the surface of the fixed plate. Here, the even distribution of the tension spring makes the connection between the fixed plate and the tension plate more stable, and also maintains the force of upper limb movement.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model incorporates a threaded block, a double screw, a top block, a bevel gear rotating handle, a seat, a slide, a slide base, and a motion frame. The engagement of the double screw and the bevel gear rotating handle allows for adjustment of the patient's movement height. Simultaneously, the rotational connection between the slide base and the motion frame allows for adjustment of the overall angle of the motion frame. This enables the customization of rehabilitation plans for different patients, adaptability to various rehabilitation programs and usage environments, optimization of movement posture and comfort, and ultimately, effective improvement of rehabilitation outcomes and experience.

[0012] 2. This utility model incorporates a fixed plate, a limiting block, a tension spring, and a pull plate. Pulling the pull plate can strengthen upper limbs, enhance the strength and endurance of shoulder, arm, and back muscles, improve shoulder joint flexibility, increase the stability of elbow and wrist joints, promote metabolism and cardiopulmonary function, and also help to shape a good body shape and improve body balance.

[0025] Example 2

[0026] Please see Figure 6 A fixed plate 17 is fixedly installed on one side of the motion frame 11. A limiting block 18 is fixedly installed on the surface of the fixed plate 17. The limiting block 18 is used to restrict the tension spring 19 from sliding on the surface of the limiting block 18.

[0027] Working principle: When a patient needs to undergo exercise rehabilitation, the patient first sits on seat 7. Then, the electric telescopic rod 9 pushes the slide seat 10 in the slide groove 8 in front of the patient. The height of the patient seat 7 is adjusted by rotating the bevel gear handle 6. One end of the bevel gear handle 6 meshes with one end of the double screw 4. Through the meshing between the bevel gear handle 6 and the double screw 4, the double screw 4 is raised and lowered by the threaded connection inside the threaded block 3. At the same time, it drives the top block 5 connected to the surface of the double screw 4. The top block 5 moves the seat 7 together, thereby adjusting the seat height. The motor 12 drives the motion frame 11 on the slide seat 10. The internal rotation allows adjustment of the angles of the foot lever 14 and hand lever 16, tailored to the patient's comfort during rehabilitation. Combined with the height adjustment of the seat 7, this helps the patient find a comfortable and suitable position for limb movement rehabilitation. The patient can then place both feet on the pedal 15 and hold the hand lever 16, allowing for simultaneous movement of all four limbs. The fixed plate 17 on one side of the exercise frame 11 connects to the tension spring 19 and the pull plate 20. The patient can also hold the pull plate 20 with both hands and pull it back towards themselves. The force generated by the tension spring 19 can help strengthen the patient's upper limbs.
