Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment technology, specifically relating to a clinical rehabilitation device. Background Technology

[0002] Limb injuries are a common type of trauma in clinical practice, which seriously affects patients' quality of life and their original ability to work. Due to prolonged lack of movement of the limbs, sequelae such as limb stiffness and inflexibility are likely to occur, leading to muscle atrophy, joint stiffness, and affecting future mobility. Therefore, appropriate limb rehabilitation training activities should be carried out for a certain period of time after surgery.

[0003] Rehabilitation bicycles are commonly used for lower limb rehabilitation training. They are typically electrically driven and structurally similar to bicycle pedals, consisting of two pedals and a connecting base. Users sit on the included seat with their feet secured to the pedals and train using preset resistance levels. While rehabilitation bicycles offer significant convenience for rehabilitation training, they also have some limitations. Because most rehabilitation bicycles are electrically driven, their use in environments without a power source is restricted. Utility Model Content

[0032] The following will be combined with the appendix Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] Please see Figures 1-4The clinical rehabilitation device 100 of this utility model embodiment includes a housing 10, a resistance component 20, and a push-pull component 30. The housing 10 has a receiving cavity 11. The upper end of the housing 10 is provided with a sliding groove 12 communicating with the receiving cavity 11. One end of the push-pull component 30 passes through the sliding groove 12 and is slidably connected to the bottom of the receiving cavity 11. The resistance component 20 is disposed in the receiving cavity 11. The resistance component 20 includes a cylinder 21, a piston 22, and a damping structure 23. One end of the cylinder 21 is connected to the side wall of the receiving cavity 11. One end of the piston 22 is slidably connected to the cylinder 21. The other end of the piston 22 is connected to the push-pull component 30. The piston 22 is provided with a variable diameter channel 24. The damping structure 23 is disposed in the cylinder 21, and one end of the damping structure 23 is connected to the cylinder 21. The other end of the damping structure 23 is slidably connected to the variable diameter channel 24.

[0034] Compared with the prior art, the clinical rehabilitation device 100 of this utility model uses a housing 10, a resistance component 20, and a push-pull component 30 in cooperation. One end of the push-pull component 30 passes through the groove 12 of the housing 10 and is slidably connected to the bottom of the receiving cavity 11. The user can move the push-pull component 30 along the groove 12 to achieve lower limb rehabilitation training. The resistance component 20 includes a cylinder 21, a piston 22, and a damping structure 23. One end of the piston 22 is slidably connected to the cylinder 21, and the other end of the piston 22 is connected to the push-pull component 30. The push-pull component 30 drives the piston 22 to slide forward or backward. The piston 22 is provided with a variable diameter channel 24, and the other end of the damping structure 23 is slidably connected to the variable diameter channel 24, which effectively makes the push-pull component 30 have resistance changes when pushed. It can be used without electricity, so users do not need to worry about power supply during rehabilitation training and can carry out rehabilitation training anytime and anywhere. In addition, the device is easy to operate, requiring no complicated settings or adjustments, and users can easily get started.

[0035] Understandably, the other end of the cylinder 21 faces the push-pull assembly 30.

[0036] Please see Figures 1-4 In some embodiments, the piston 22 includes a piston head and a piston rod 222. One end of the piston rod 222 is connected to the piston head, and the other end of the piston rod 222 is connected to the push-pull assembly 30. The variable diameter channel 24 includes a first segment 241 and a second segment 242 that are connected. The diameter of the first segment 241 is smaller than the diameter of the second segment 242. The first segment 241 is disposed on the piston rod 222, and the second segment 242 is disposed on the piston head. The other end of the damping structure 23 passes through the second segment 242 and the first segment 241 in sequence, and the other end of the damping structure 23 is slidably connected to the second segment 242 and the first segment 241.

[0037] The coordinated use of the piston head 22 and piston rod 222, and the connection design of the piston head 22 and piston rod 222, allows the piston 22 to maintain good integrity and stability during movement. This design helps reduce the shaking and deformation of the piston 22 during movement, thereby improving the reliability and durability of the rehabilitation device 100. Through the coordinated use of the first segment 241 and the second segment 242, with the diameter of the first segment 241 being smaller than that of the second segment 242, when the piston 22 slides under the action of the push-pull assembly 30, the damping structure 23 passes sequentially through the second segment 242 and the first segment 241. Due to the change in diameter, the resistance gradually increases. This design allows the resistance during training to change smoothly with the movement of the piston 22, avoiding sudden changes in resistance and providing users with a more adaptive training experience.

[0038] Please see Figure 4 In some embodiments, the diameter of the first segment 241 gradually decreases from the second segment 242 towards the first segment 241. By gradually reducing the diameter of the first segment 241, the resistance can be varied more precisely and smoothly during the movement of the piston 22. This design allows the piston 22 to remain stable when subjected to the thrust of the push-pull assembly 30, reducing swaying and instability caused by changes in resistance, thereby extending the service life of the device.

[0039] Please see Figures 1-4 In some embodiments, the damping structure 23 includes a damping head 231 and a damping adjustment rod 232. The damping head 231 is disposed between the piston head 22 and one end of the cylinder 21. One end of the damping adjustment rod 232 is connected to the damping head 231, and the other end of the damping adjustment rod 232 passes sequentially through the second segment 242 and the first segment 241, and the damping adjustment rod 232 is slidably connected to the second segment 242 and the first segment 241. Through the cooperative use of the damping head 231 and the damping adjustment rod 232, the damping adjustment rod 232 is connected to the damping head 231 and slidably connected to the second segment 242 and the first segment 241. When the piston 22 slides under the action of the push-pull assembly 30, the damping structure 23 passes sequentially through the second segment 242 and the first segment 241. Due to the change in diameter, the resistance gradually increases. This design allows the resistance during training to change smoothly with the movement of the piston 22, avoiding abrupt changes in resistance, thereby providing users with a more adaptive training experience.

[0040] Understandably, the damping head 231 and the damping adjustment rod 232 are integrally molded structures. This effectively enhances the connection strength between the two, making the entire structure more stable. Due to the increased connection strength, the integrally molded structure can withstand greater forces, thereby improving the durability of the rehabilitation device 100 and reducing safety risks caused by device malfunction or damage.

[0041] Please see Figure 4 In some embodiments, the diameters at both ends of the damping adjustment rod 232 are larger than the diameter at the middle. By setting the diameter of the damping adjustment rod 232 so that the diameters at both ends are larger than the diameter at the middle, the resistance when the piston 22 slides from the middle to both ends of the damping adjustment rod 232 is effectively increased. The increased resistance increases the load during training, which helps to gradually enhance muscle strength and promote the rehabilitation process.

[0042] Please see Figure 4 In some embodiments, the diameter of the damping adjustment rod 232 decreases progressively from both ends toward the middle. This effectively increases the resistance as the piston 22 slides from the middle to both ends of the damping adjustment rod 232. This gradual increase in resistance makes the speed change of the piston 22 during sliding smoother, avoiding motion instability caused by sudden changes in resistance. This smooth motion process not only improves training safety but also provides users with a more comfortable training experience.

[0043] Understandably, the surfaces of the housing 10 located on both sides of the slide opening 12 are marked with resistance range indicators. During rehabilitation training, users can directly refer to these indicators to adjust the push-pull component 30 to the corresponding resistance range, effectively allowing them to conduct rehabilitation training according to different resistance requirements. Simultaneously, during self-training, users can dynamically adjust the resistance by observing the indicators to achieve a gradual increase in intensity.

[0044] Please see Figure 1 and Figure 4 In some embodiments, a first airbag 25 is disposed within the cylinder 21, located between one end of the cylinder 21 and the damping structure 23. By adjusting the amount of gas within the first airbag 25, its volume can be flexibly altered, thereby affecting the working state of the damping structure 23 and achieving continuously adjustable resistance. This design allows the rehabilitation device 100 to adapt to the personalized training needs of different users, improving the targeting and effectiveness of rehabilitation training. Simultaneously, the first airbag 25 possesses excellent cushioning and shock absorption properties. During rehabilitation training, when the piston 22 moves rapidly or encounters significant resistance, the first airbag 25 can absorb and disperse the impact force, reducing the direct impact of movement on joints and muscles, and lowering the risk of sports injuries. This design helps protect the patient's joints and muscles, improving the safety of training.

[0045] Please see Figures 1-3In some embodiments, the push-pull assembly 30 includes a first rod 31, a second rod 32, a first slider 33, and a foot pedal 34. A first slide rail 13 is provided at the bottom of the housing 10. The first slider 33 is slidably mounted on the first slide rail 13. One end of the first rod 31 is connected to the first slider 33, and the other end of the first rod 31 passes through a slide groove 12 and is connected to the second rod 32. The first rod 31 and the second rod 32 are perpendicular to each other. Two foot pedals 34 are provided, spaced apart on the second rod 32. The other end of the piston 22 is connected to the first rod 31. Through the coordinated use of the first rod 31, the second rod 32, the first slider 33, and the foot pedal 34, the first slider 33 is slidably mounted on the first slide rail 13 of the housing 10, allowing the push-pull assembly 30 to slide along the slide rail. This effectively guides the sliding of the push-pull assembly 30, enhances its stability, reduces potential shaking or deviation during training, and improves training safety. Two foot pedals 34 are spaced apart on the second rod 32. The first rod 31 is connected to the other end of the piston 22. The user can slide the first rod 31 and the second rod 32 forward or backward by using the foot pedals 34, so that the position of the piston 22 on the cylinder 21 changes. By adjusting the position of the piston 22, the resistance can be changed. This design helps to improve the pertinence and effectiveness of rehabilitation training and promote the user's rehabilitation process.

[0046] Please see Figure 1 and Figure 3In some embodiments, each foot pedal 34 is provided with a second airbag 341 and a third airbag 342, which are spaced apart and connected by an air duct 343. Through the coordinated use of the second airbags 341 and 342, they act as cushioning elements, providing additional support and cushioning when the user steps on the foot pedal 34, reducing impact and fatigue on the feet. This design makes the rehabilitation training process more comfortable and helps users persist with training for longer periods. An air duct 343 connects the second airbag 341 and the third airbag 342, effectively allowing them to communicate. During rehabilitation training, the user's heel is positioned in the second airbag 341, and the forefoot in the third airbag 342. When the foot pedal 34 is pushed forward, the heel is stressed, and some gas from the second airbag 341 flows through the air duct 343 to the third airbag 342, increasing its volume and lifting the forefoot. Conversely, when the foot pedal 34 is pulled backward, the forefoot is stressed, and some gas from the third airbag 342 flows through the air duct 343 to the second airbag 341, increasing its volume and lifting the heel. This dynamic gas flow and airbag volume change enable the rehabilitation device 100 to better simulate a real gait, enhancing the targeting and effectiveness of the training.

[0047] Please see Figures 1-3 In some embodiments, second slide rails 14 are provided on both sides of the housing 10, and a second slider 35 is provided on the first rod 31. The second slider 35 is slidably connected to the second slide rail 14. Through the cooperative use of the second slide rail 14 and the second slider 35, the slidable connection of the second slider 35 on the second slide rail 14 provides a stable guide for the movement of the first rod 31, making the device less prone to deviation or shaking during movement, thereby improving the stability and safety of training.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
