Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rehabilitation training devices, and particularly relates to a training device for rehabilitation. BACKGROUND

[0002] Postoperative patients in neurosurgery (such as after stroke, brain tumor, craniocerebral injury) often have sequelae such as upper limb motor dysfunction, reduced grip strength, and abnormal gait of lower limbs. Effective rehabilitation training is crucial for promoting neural functional remodeling and restoring the self-care ability of patients. However, the existing rehabilitation training technology and device have many limitations in clinical application, and it is difficult to meet the needs of modern neurorehabilitation medicine.

[0003] At present, the related rehabilitation equipment commonly used in clinical practice mainly includes the following types: single function training device: this is the most common form. Upper limb and grip strength training: such as dumbbells, elastic bands, grip strength trainers, hand function boards, etc. This type of equipment has simple structure and low cost, but the training mode is highly repetitive and extremely boring, resulting in poor patient compliance. More importantly, they can only perform isolated, open-loop muscle training and cannot simulate functional tasks, nor can they provide real-time feedback on the training process. Lower limb gait training: such as stationary bicycles, treadmills, etc. They mainly focus on the alternating movement of the lower limbs, but are usually completely disconnected from upper limb training and cannot train the “upper and lower limb coordination” function which is crucial in natural human movement.

[0004] Comprehensive rehabilitation robots: exoskeleton robots or end-effector traction robots (such as ARMGuide, Lokomat, etc.) have appeared in recent years, which can provide precise and repetitive training. However, such equipment generally has problems such as high cost, complex structure, and large floor space, and is usually focused on the training of a single limb (or upper limb or lower limb), making it difficult to popularize in primary hospitals, communities or families. At the same time, the training mode is often dominated by the machine, and the active participation and interest of the patient still need to be improved.

[0005] Task-oriented training equipment: Some devices based on virtual reality (VR) or game interaction attempt to increase interest to improve participation. However, they usually rely on screen visual feedback, lack real proprioception and tactile feedback, and the system relies on software and hardware, which poses challenges to stability and reliability.

[0006] Based on the above summary, the prior art mainly exists the following urgent problems to be solved: function isolation, lack of coordination: the traditional "headache medicine head, foot pain medicine foot" training method separates upper and lower limb training, ignores the bilateral coordination and proximal-distal coordination mode relearning which is crucial in nerve rehabilitation. This is not conducive to the brain to form a complete motor control network. Intensity adjustment is discontinuous, and it is difficult to accurately match the rehabilitation process: the resistance adjustment of most mechanical devices is stepped, ladder type (such as replacing weight blocks or adjusting limited resistance gears). For neurosurgical patients in the rapid recovery period, it often appears that "the last gear is too easy, and the next gear is too difficult", which cannot achieve smooth, stepless progressive load, affecting the rehabilitation efficiency, and even may cause secondary injury due to improper intensity.

[0007] In summary, there is an urgent need in the art for a neurosurgical rehabilitation training device that can integrate upper and lower limb functions, provide smooth and progressive resistance, stimulate the patient's active participation, and provide intuitive functional feedback, and the cost is relatively controllable. For this purpose, the inventor designs a cooperative rehabilitation device integrating upper limb traction, grip strengthening, and lower limb gait training. Through a clever mechanical linkage structure, the patient's active movement is converted into meaningful task goals, thereby effectively overcoming the above-mentioned defects of the prior art. SUMMARY

[0008] In view of the above problems, the present application aims to provide a training device for rehabilitation, which can separate or link the upper limb training mechanism and the lower limb training mechanism through the linkage assembly, breaking the barrier of functional isolation of existing rehabilitation training equipment. Through mechanical linkage design, the upper limb traction, grip and lower limb gait training are organically combined in a coherent motion, improving the overall motor coordination of the training patient, not just isolated muscle strength, and more in line with the "task-oriented" concept of modern neurorehabilitation. The patient can select the track radius and the elastic resistance generated by the spring to make the device have a smooth, progressive, stepless resistance adjustment mechanism, so that the training load can seamlessly match the patient's real-time ability limit, achieving personalized, efficient and safe rehabilitation stimulation. The combination of the two makes the device a comprehensive neurosurgical rehabilitation training device with reasonable structure, controllable cost, effective upper and lower limb coordination, stepless progressive intensity, and real-time feedback of active training goals for patients, to overcome the shortcomings of the prior art and improve the efficiency and experience of rehabilitation training.

[0039] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] See attached document Figures 1-18 The rehabilitation training device shown includes an upper limb training mechanism and a lower limb training mechanism. The upper limb training mechanism is positioned above the lower limb training mechanism. The upper limb training mechanism includes two mounting boxes 1, a selection disc 3, and a resistance component. The two mounting boxes 1 are symmetrically mounted on two connecting frames 2. The selection disc 3 is located at the opening of the mounting box 1 and is used to select the training intensity. The resistance component is located inside the mounting box 1 and is used to provide load for the training intensity selected by the selection disc 3. The resistance component includes a track disc 4, multiple airbags 5, and a linkage component. The track disc 4 is located inside the mounting box 1 and has a multi-layered roller shape at the rear end. The multiple airbags 5 are located on the track disc 4 and are used to connect to the selection disc 3 to provide resistance for upper limb training. The linkage component is connected to the multiple airbags 5 and is used to link the upper limb training mechanism and the lower limb training mechanism.

[0041] Specifically, two connecting frames 2 are symmetrically arranged on both sides of the mounting frame 9, and two mounting boxes 1 are symmetrically fixedly installed on the two connecting frames 2. Two selection discs 3 are arranged in opposite directions at the opening of the mounting box 1, and two track discs 4 are arranged in opposite directions inside the mounting box 1. Multiple tracks are provided on the track disc 4, and multiple airbags 5 are respectively arranged in the corresponding tracks. The rear ends of the multiple airbags 5 are all fixedly connected to the corresponding tracks. The rear end of the track disc 4 is multi-layered roller-shaped. The front ends of the multiple airbags 5 are connected to the linkage component through the multi-layered rollers at the rear end of the track disc 4. The front ends of the multiple airbags 5 are correspondingly arranged on the selection disc 3, and can freely select and communicate with the front ends of the airbags 5 in the corresponding tracks through the selection disc 3.

[0042] More specifically, the two selection discs 3 and two track discs 4 are divided into two groups. One group of selection discs 3 and track discs 4 is set in a clockwise direction on one side of the mounting box 1, and the other group of selection discs 3 and track discs 4 is set in a counterclockwise direction on the other side of the mounting box 1. During training, the patient's left and right hands perform opposite movements simultaneously to complete upper limb training, which is beneficial for neurosurgical rehabilitation training.

[0043] In some embodiments, the linkage assembly includes a drive belt 6, a belt deflector 7, and a toothed drive chain 8: multiple drive belts 6 are connected to the rear end of the track disc 4; multiple belt deflectors 7 are disposed on the side of the lower limb training mechanism to change the direction of travel of the drive belts 6; two toothed drive chains 8 are disposed on the lower limb training mechanism and cooperate with the drive belts 6 to drive the movement of the lower limb training mechanism. Each of the multiple drive belts 6 is provided with a locking block 18, and each of the two toothed drive chains 8 has a locking groove 19 on its outer side. The locking block 18 is adapted to the locking groove 19, and the drive belt 6 drives the toothed drive chain 8 to move through the locking block 18.

[0044] Specifically, the upper ends of multiple transmission belts 6 are wound around the multi-layer rollers at the rear end of the track disc 4. The outer side of the upper end of each transmission belt 6 is fixedly connected to the rear end of each airbag 5. Multiple belt deflectors 7 are set on the side of the lower limb training mechanism. The lower end of each transmission belt 6 is correspondingly sleeved on a belt deflector 7. A snap-fit ​​block 18 is fixedly connected to the outer side of the lower end of each transmission belt 6 near the belt deflector 7. Two sawtooth transmission chains 8 are symmetrically arranged on the inner sides of both sides of the lower limb training mechanism. A snap-fit ​​groove 19 is opened on the outer side of each of the two sawtooth transmission chains 8. The snap-fit ​​block 18 is adapted to the snap-fit ​​groove 19.

[0045] More specifically, when the selection disc 3 drives the front end of the airbag 5 to move along the track of the track disc 4, the airbag 5 drives the corresponding transmission belt 6 to rotate around the multi-layer rollers at the rear end of the track disc 4. The locking block 18, which is fixedly connected to the lower outer side of the transmission belt 6, is embedded in the locking groove 19, so that the sawtooth transmission chain 8 and the transmission belt 6 become a whole. When the transmission belt 6 passes the belt deflector 7, the movement trajectory of the transmission belt 6 is temporarily changed, so that the transmission belt 6 drives the sawtooth transmission chain 8 to move horizontally along the lower limb training mechanism, and then drives the lower limb training mechanism to move together. Each training cycle of the upper limb training mechanism of this device is a circle, and then it returns along the same path. After the return action is completed, the locking block 18 disengages from the locking groove 19.

[0046] In some embodiments, the lower limb training mechanism includes a mounting frame 9, tracks 10, and a telescopic push-pull frame 11: the mounting frame 9 is used to mount the connecting frame 2 and the electric mechanism; two tracks 10 are disposed on both sides of the mounting frame 9, and the outer ends of the tracks 10 are toothed, adapted to the sawtooth transmission chain 8; the telescopic push-pull frame 11 is connected between the two tracks 10 and is used to change the position of the two tracks 10. The electric mechanism includes a motor 20 and a rotating shaft 21: two motors 20 are disposed on the mounting frame 9; two rotating shafts 21 are rotatably connected to both ends inside the mounting frame 9, respectively connected to the output ends of the two motors 20, and the two tracks 10 are wound around the surfaces of the two rotating shafts 21.

[0047] Specifically, rotating shafts 21 are rotatably connected to both ends of the inner side of the mounting frame 9. Bearing wheels 23 are provided at both ends of the rotating shafts 21. A connecting frame 2 is symmetrically fixedly connected to the middle position of the top of the mounting frame 9. Two motors 20 are respectively mounted on the mounting frame 9, and the two rotating shafts 21 are respectively connected to the output ends of the two motors 20. Two tracks 10 are wound around the two sets of rotating shafts 21. A track 10 is fixedly connected to each end of the telescopic push-pull frame 11. The outer ends of the tracks 10 are toothed, matching the teeth of the sawtooth drive chain 8. The sawtooth drive chain 8 is mounted on the two sets of bearing wheels 23. When the telescopic push-pull frame 1... When the device extends, it simultaneously pushes the two tracks 10 connected to both ends, causing the teeth on the sides of the two tracks 10 to mesh with the teeth on the sawtooth transmission chain 8, forming a whole. The tracks 10 will move back and forth with the training level of the upper limb training mechanism. When the telescopic push-pull frame 11 retracts, it simultaneously pulls the two tracks 10 connected to both ends inward, causing the tracks 10 to separate from the sawtooth transmission chain 8. At this time, the motor 20 is started, and the motor 20 drives the rotating shaft 21 to rotate synchronously, so that the two tracks 10 rotate synchronously without affecting the upper limb training mechanism. It is used for lower limb training alone, similar to existing treadmills.

[0048] In some embodiments, each of the plurality of airbags 5 includes a connecting block 12 and a sealing connector 13: the connecting block 12 is fixedly connected to the rear side of the airbag 5 and is used to connect the transmission belt 6 through the track disk 4; the sealing connector 13 is disposed on the front side of the airbag 5 and is used to connect the selection disk 3. The selection disk 3 also includes a rotating connecting point 14, a connecting spring 15, a connecting rod 16, and a grip ball 17: the rotating connecting point 14 is rotatably connected to the center position of the selection disk 3; the connecting spring 15 is connected to the rotating connecting point 14 and uses its elasticity to select different training intensity paths of the selection disk 3; the connecting rod 16 is connected to the end of the connecting spring 15 and is used to connect to the sealing connector 13; the grip ball 17 is connected to the end of the connecting rod 16 and is used to train the patient's gripping ability. The connecting rod 16 is a telescopic rod, and a switch 22 is provided on the connecting rod 16, the switch 22 being used to control the extension and retraction of the connecting rod 16.

[0049] Specifically, multiple airbags 5 are arranged at the front end of the track plate 4. One end of the airbag 5 with a sealing insertion interface 13 is taken as the head end and the other end as the tail end. The tail end of the airbag 5 is fixedly connected to the track plate 4 by adhesive bonding, and the head end is movably connected inside the track plate 4. The connecting block 12 is fixedly connected to the rear side of the airbag 5. The connecting block 12 is fixedly connected to the outside of the transmission belt 6 through the track plate 4. The rotating connection point 14 is rotatably connected to the center position of the selection plate 3. The connecting spring 15 is connected to the rotating connection point 14. The plug rod 16 is connected to the end of the connecting spring 15. The grip ball 17 is connected to the end of the plug rod 16. The plug rod 16 is a telescopic rod and a switch 22 is provided on the plug rod 16.

[0050] More specifically, at the start of training, the patient grips the grip ball 17 and the connecting rod 16, using their upper limb strength to overcome the tension of the connecting spring 15 and move the connecting rod 16 into the corresponding training track. The side wall of the training track presses against the switch 22, causing the connecting rod 16 to extend and insert into the sealing connector 13, connecting the airbag 5 to the grip ball 17. During training, the patient's hand grips the grip ball 17, which drives the connecting rod 16. The corresponding airbag 5 moves along the track disc 4 under the influence of the connecting rod 16 and the grip ball 17. The transmission belt 6 corresponding to the airbag 5 is carried by the connecting block 12 to move around the rear of the track disc 4. During the movement, the airbag 5 is compressed. The internal air is compressed and enters the grip ball 17 through the plug rod 16 and the sealed plug interface 13, inflating the grip ball 17. As the track radius gradually increases, the training intensity can be increased. When the end of the circular track is reached, the spring tension reaches its maximum, the patient's upper limb relaxes, and under the reset action of the connecting spring 15, it returns to the starting point with little effort. The gas in the grip ball 17 returns to the air bladder 5, the switch 22 releases the pressure and retracts the plug rod 16, and the patient can select the track again and repeat the training. The patient can also train multiple times on the same track. The trainee can train not only the arm but also the gripping ability of the hand, which is helpful for neurosurgical rehabilitation training.

[0051] This device is used for rehabilitation training of neurosurgical patients, and can be divided into three modes: Upper limb training mode: Two selection discs 3 and two track discs 4 are divided into two groups. One group of selection discs 3 and track discs 4 is set clockwise on one side of the mounting box 1, and the other group of selection discs 3 and track discs 4 is set counterclockwise on the other side of the mounting box 1. During training, the patient's left and right hands perform opposite movements simultaneously. The patient holds the grip ball 17 and the connecting rod 16 and uses their own upper limb strength to overcome the tension of the connecting spring 15 to move the connecting rod 16 into the corresponding training track. When the connecting rod 16 is moved into the training track, the side wall of the training track will press the switch 22, causing the connecting rod 16 to extend and insert into the sealing connector 13, connecting the airbag 5 and the grip ball 17. During training, the patient's hand grasps the grip ball 17, which drives the connecting rod 16, the corresponding airbag 5, and the corresponding transmission. The belt 6 moves synchronously. During the movement, the airbag 5 is compressed, and the air inside is squeezed and enters the grip ball 17 through the plug rod 16 and the sealed plug interface 13, inflating the grip ball 17. As the track radius gradually increases, the training intensity can be increased. When the end of the circular track is reached, the spring tension reaches its maximum, the patient's upper limb relaxes, and under the reset action of the connecting spring 15, the patient returns to the starting point with little effort. The gas in the grip ball 17 returns to the airbag 5, the switch 22 releases the pressure and retracts the plug rod 16, and the patient can select the track again for the next time and repeat the training. The patient can also train multiple times on the same track. The trainee can train not only the arm but also the gripping ability of the palm, which is helpful for neurosurgical rehabilitation training to complete upper limb training and is beneficial for neurosurgical rehabilitation training.

[0052] Lower limb training mode: The telescopic push-pull frame 11 is retracted by the controller, simultaneously pulling the two tracks 10 connected to both ends inward, causing the tracks 10 to separate from the sawtooth transmission chain 8. At this time, the motor 20 is activated, driving the rotating shaft 21 to rotate synchronously, causing the two tracks 10 to rotate synchronously. This does not involve the upper limb training mechanism and is used solely for lower limb training, similar to existing treadmills. Patients can perform lower limb exercises such as slow walking or jogging on it. The controller controlling the motor and the telescopic push-pull frame 11 are existing mature technologies, so they will not be described in detail in this article but will be directly cited.

[0053] Coordinated training mode: The motor 20 is turned off, and the telescopic push-pull frame 11 is extended by the controller. At the same time, the two tracks 10 connected to both ends are pushed to move outward, so that the tracks 10 mesh with the sawtooth transmission chain 8. Then, the upper limbs are trained by the method in the upper limb training mode. During the operation of the upper limb training mechanism, the airbag 5 drives the corresponding transmission belt 6 to rotate around the multi-layer roller at the rear end of the track plate 4. The snap block 18 fixedly connected to the lower outer side of the transmission belt 6 is embedded in the snap slot 19, so that the sawtooth transmission chain 8 and the transmission belt 6 become a whole. When the transmission belt 6 passes the belt deflector 7, the movement trajectory of the transmission belt 6 is temporarily changed, so that the transmission belt 6 drives the sawtooth transmission chain 8 to move horizontally along the lower limb training mechanism, and then drives the lower limb training mechanism to move together. Each training cycle of the upper limb training mechanism of this device is a circle, and then it returns along the same path. After the return action is completed, the snap block 18 disengages from the snap slot 19. In this process, since the two selection discs 3 and two track discs 4 are divided into two groups, one group of selection discs 3 and track discs 4 is set clockwise on one side of the mounting box 1, and the other group of selection discs 3 and track discs 4 is set counterclockwise on the other side of the mounting box 1. During training, the patient's left and right hands perform opposite movements synchronously. At the same time, the lower limb training mechanism is affected by the unique setting of the upper limb training mechanism, and the two tracks 10 also move back and forth in an alternating manner. During this training process, the patient's arms, grip strength and lower limbs are exercised at the same time, which has the effect of comprehensively training the patient's physical coordination ability and is more conducive to neurosurgical rehabilitation training.
