Description

Technical Field

[0001] This application relates to the field of stroke rehabilitation technology, and in particular to a multifunctional assistive device for rehabilitation training of ischemic stroke. Background Technology

[0002] Ischemic preconditioning (IPC) training devices simulate transient limb ischemia and reperfusion processes to stimulate the body's self-protective mechanisms, thereby enhancing tolerance to cerebral ischemia (such as stroke). Studies have shown that regular ischemic preconditioning training can significantly reduce the risk of stroke, improve cerebral blood flow reserve, and may alleviate neurological function damage after stroke. Its effects are closely related to the activation of the body's endogenous protective pathways (such as the RISK pathway and SAFE pathway).

[0003] A search revealed Chinese Patent Publication No. CN220142084U, which discloses a rehabilitation training device for ischemic stroke, including a motor, a winding drum, a transmission belt, and a collection drum. When the motor is started, it drives the winding drum connected to the upper end to wind, causing the restraint belt to gradually wrap around the outside of the winding drum. At this time, the gap between the restraint belt and the sponge pad gradually decreases, and the restraint belt gradually approaches the lower leg. When the lower leg experiences a noticeable feeling of restraint, the motor stops rotating, ensuring a stable connection between the lower leg and the fixation plate. The sponge pad between the lower leg and the fixation plate reduces the foreign body sensation caused by the fixation plate. The operation can be completed by driving the motor without the need for caregivers to bend over or bend their knees. The motor's drive switch is located around the handrail, allowing the patient to start the motor themselves for self-fixation, making operation more convenient.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing ischemic stroke rehabilitation training devices cannot be adjusted to the patient's comfortable position during actual use. A comfortable position can improve blood flow and increase the patient's acceptance of the device. Furthermore, existing devices cannot move according to the patient's wishes, and cannot simulate the patient's exertion in daily life during training, thus reducing the training effect. Moreover, patients with severe ischemic stroke who are alone at home cannot use the training device independently. Therefore, we propose a multifunctional assistive device for ischemic stroke rehabilitation training. Utility Model Content

[0023] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0024] This application discloses a multifunctional assistive device for rehabilitation training of ischemic stroke. For example... Figure 1 and Figure 3 As shown, including,

[0025] Please see Figure 1 , Rehabilitation chair 1, with armrests 8 fixedly connected to the top of rehabilitation chair 1, and rehabilitation device 7 fixedly installed at the bottom of rehabilitation chair 1;

[0026] Adjustment training mechanism 3 is used for body position adjustment and strength training. Adjustment training mechanism 3 includes a back panel 2 that rotates on the top of rehabilitation chair 1. The right side of rehabilitation chair 1 is connected to two legs 5 with damping rotation. The top of the legs 5 is fixedly connected to a positioning plate 6.

[0027] Please see Figure 2 The adjustment training mechanism 3 also includes two rotating shafts 15 fixedly connected to one side of the rehabilitation chair 1. The rotating ends of the two rotating shafts 15 are fixedly connected to one end of the adjacent foot frame 5. A second fixing rod 11 is fixedly connected to the bottom of the rehabilitation chair 1. Two second hydraulic cylinders 12 are rotatably mounted on the outside of the second fixing rod 11. A rotating shaft 13 is fixedly connected to the telescopic end of the second hydraulic cylinder 12. A damping rod 14 is fixedly connected to one end of the rotating shaft 13. The output end of the damping rod 14 is fixedly connected to one end of the adjacent foot frame 5.

[0028] Please see Figure 3 and Figure 4 The top of the rehabilitation chair 1 is rotatably connected to the back panel 2, and the bottom of the rehabilitation chair 1 is fixedly connected to the first fixing rod 9. The outside of the first fixing rod 9 is rotatably mounted with the first hydraulic cylinder 10, and the telescopic end of the first hydraulic cylinder 10 is rotatably connected to the bottom of the back panel 2.

[0029] The above-mentioned structure can adjust the patient's position and provide appropriate strength training when the patient is undergoing rehabilitation training for stroke, so as to avoid muscle atrophy and soft tissue adhesion around the joints, enhance muscle strength and motor function, promote the recovery of nerve function, improve metabolism and cardiopulmonary function, and enhance balance and coordination. Specifically, when training is needed, the patient sits on the top of the rehabilitation chair 1 with his back against the backboard 2 and his legs placed on the top of the positioning plate 6.

[0030] When the leg height needs to be adjusted, the second hydraulic cylinder 12 is activated. The extension end of the second hydraulic cylinder 12 drives the rotating shaft 13 to move. The movement of the rotating shaft 13 drives the damping rod 14 to move. The movement of the damping rod 14 drives the footrest 5 to rotate around the rotating shaft 15. At the same time, the second hydraulic cylinder 12 rotates outside the second fixed rod 11, and the rotating shaft 13 rotates itself to prevent the second hydraulic cylinder 12 from jamming during operation, thus completing the adjustment of the patient's leg height.

[0031] When the back angle needs to be adjusted, the first hydraulic cylinder 10 is activated. The extension end of the first hydraulic cylinder 10 drives the back plate 2 to rotate on the top of the rehabilitation chair 1. At the same time, the first hydraulic cylinder 10 rotates outside the first fixed rod 9, and the extension end of the first hydraulic cylinder 10 rotates at the bottom of the back plate 2 to prevent the first hydraulic cylinder 10 from getting stuck, thus completing the adjustment of the patient's back angle.

[0032] At this time, rehabilitation equipment 7 is used to perform rehabilitation training on the patient. When strength training is required during the rehabilitation training, the damping rod 14 is activated to adjust the torque value of the footrest 5 rotating around the pivot 15. At this time, the patient can perform strength training by reciprocating leg raises.

[0033] It is worth mentioning that the device allows patients to adjust their position to lie down or sit up;

[0034] The supine position avoids the risk of falls due to insufficient muscle strength that may occur when sitting. It is especially suitable for patients with limb weakness or balance disorders. At the same time, when lying down, the lower limbs and heart are at the same level, blood circulation is more stable, which is conducive to precise control of ischemia-reperfusion pressure.

[0035] Sitting posture, which mimics daytime activity, may better meet the needs of "pre-adaptive" protective mechanisms (such as counteracting changes in cerebral blood flow when standing / walking). Furthermore, with the lower limbs dangling in a sitting position, gravity-assisted venous return may enhance reperfusion.

[0036] Please see Figure 1 , Figure 5 and Figure 6 The fixing mechanism 4 facilitates the use of the ischemic stroke rehabilitation training device. The fixing mechanism 4 includes four rehabilitation air bags 20 connected to the output end of the rehabilitation device 7. Spring steel plates 21 are fixedly connected inside the rehabilitation air bags 20. Spring steel wires 22 are also fixedly connected inside the rehabilitation air bags 20. Velcro 23 is fixedly connected to the outside of the rehabilitation air bags 20.

[0037] The fixing mechanism 4 also includes a first air pipe 17 and a second air pipe 18 connected to the output end of the rehabilitation instrument 7. There are two of each of the first air pipe 17 and the second air pipe 18. Among the four rehabilitation air bags 20, two rehabilitation air bags 20 are fixedly connected to one side of the adjacent positioning plate 6, and the other two rehabilitation air bags 20 are movably set on the top of the adjacent handrail 8.

[0038] Two first air tubes 17 pass through adjacent positioning plates 6 and are connected to the rehabilitation air bag 20 thereon. Two second air tubes 18 pass through adjacent handrails 8. The top of each of the two second air tubes 18 is connected to a telescopic tube 16. The top of the telescopic tube 16 is connected to the bottom of the rehabilitation air bag 20. The top of each of the two handrails 8 is fixedly connected to a fixing frame 19. The bottom of the rehabilitation air bag 20 at the top of each of the two handrails 8 is adapted to the top of the adjacent fixing frame 19.

[0039] The above-mentioned structure facilitates individual use of rehabilitation training by the patient. Specifically, before using the rehabilitation air bag 20, the rehabilitation air bag 20 is unfolded. At this time, the spring steel sheet 21 is flat and bent, and the spring steel wire 22 is flat at the same time. The patient can then sit on the top of the rehabilitation chair 1. When the patient places the area to be trained on the top of the rehabilitation air bag 20, the spring steel sheet 21 is squeezed. At this time, the spring steel sheet 21 returns to its original position, and the rehabilitation air bag 20 is fixed by the Velcro 23. Then the rehabilitation device 7 can be started to carry out rehabilitation training.

[0040] It is worth mentioning that the telescopic tube 16 allows the patient to reduce the air pressure of the rehabilitation air bag 20 and improve blood flow by moving their arm when they are uncomfortable. At the same time, the telescopic tube 16 facilitates the patient's hand movements.

[0041] The implementation principle of a multifunctional assistive device for rehabilitation training of ischemic stroke according to an embodiment of this application is as follows: When training is required, the rehabilitation air bag 20 is first unfolded. At this time, the spring steel sheet 21 is flat and bent, and the spring steel wire 22 is flat at the same time. The patient can sit on the top of the rehabilitation chair 1 and lean against the back board 2. Then, the patient places their legs on the top of the positioning plate 6. When the patient places the part to be trained on the top of the rehabilitation air bag 20, the spring steel sheet 21 is squeezed. At this time, the spring steel sheet 21 returns to its original position, and the rehabilitation air bag 20 is fixed by the Velcro 23. Then the rehabilitation device 7 can be started to carry out rehabilitation training.

[0042] When the leg height needs to be adjusted, the second hydraulic cylinder 12 is activated. The extension end of the second hydraulic cylinder 12 drives the rotating shaft 13 to move. The movement of the rotating shaft 13 drives the damping rod 14 to move. The movement of the damping rod 14 drives the footrest 5 to rotate around the rotating shaft 15. At the same time, the second hydraulic cylinder 12 rotates outside the second fixed rod 11, and the rotating shaft 13 rotates itself to prevent the second hydraulic cylinder 12 from jamming during operation, thus completing the adjustment of the patient's leg height.

[0043] When the back angle needs to be adjusted, the first hydraulic cylinder 10 is activated. The extension end of the first hydraulic cylinder 10 drives the back plate 2 to rotate on the top of the rehabilitation chair 1. At the same time, the first hydraulic cylinder 10 rotates outside the first fixed rod 9, and the extension end of the first hydraulic cylinder 10 rotates at the bottom of the back plate 2 to prevent the first hydraulic cylinder 10 from getting stuck, thus completing the adjustment of the patient's back angle.

[0044] When strength training is required during rehabilitation, the damping rod 14 is activated to adjust the torque value of the footrest 5 rotating around the pivot 15, allowing the patient to perform strength training by reciprocating leg raises.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
