Description

Technical Field

[0001] This invention relates to the field of medical device rehabilitation equipment technology, and in particular to a spinal cord injury rehabilitation exercise device and exercise method. Background Technology

[0002] Spinal cord injury is often caused by external trauma such as traffic accidents, falls from heights, and impacts from heavy objects. It directly leads to motor and sensory dysfunction in the limbs below the level of injury. Patients commonly experience complications such as lower limb muscle atrophy, joint stiffness, weak back muscles, and limited upper limb movement. Prolonged bed rest or sitting can also cause secondary conditions such as urinary tract infections, bedsores, and poor blood circulation, severely reducing patients' quality of life. Targeted limb rehabilitation exercises and posture correction training are key treatment methods for promoting nerve function repair, delaying muscle degeneration, and restoring limb mobility in patients with spinal cord injury.

[0003] When using existing technical solutions, most rehabilitation equipment seats are fixed structures, making it difficult to adaptively adjust the seat's fore-and-aft position and backrest tilt angle according to the patient's height and the degree of lumbar and back injury. This makes it difficult to match the different patients' spinal physiological curvatures, resulting in poor lumbar and back support comfort.

[0004] To address the above problems, the present invention provides a spinal cord injury rehabilitation exercise device. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where the seat of the spinal cord injury rehabilitation exercise device cannot be adaptively adjusted and the upper and lower limb training is not coordinated, and to propose a spinal cord injury rehabilitation exercise device and exercise method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spinal cord injury rehabilitation exercise device, comprising a support base, a spinal chair adjustment mechanism, a lower limb training mechanism, and an upper limb training mechanism, wherein the spinal chair adjustment mechanism, the lower limb training mechanism, and the upper limb training mechanism are fixedly connected to the top of the support base, and the lower limb training mechanism and the upper limb training mechanism are symmetrically fixedly connected to both sides of the top of the support base.

[0007] The spinal chair adjustment mechanism includes a roller rotation transmission device, teeth and plates, and a T-shaped positioning slider; the lower limb training mechanism includes a telescopic spring and a rotating support column.

[0008] The spinal seat adjustment mechanism also includes seat support frames symmetrically fixedly connected to both sides of the top of the support base. A fixed plate is fixedly connected inside the symmetrically arranged seat support frames. The roller rotation transmission device is fixedly connected inside the fixed plate. Transmission gears are symmetrically fixedly connected to the outer surface of the roller rotation transmission device. The symmetrically arranged transmission gears and the gear plate are mutually connected.

[0009] Furthermore, a seat fixing frame is fixedly connected to the top of the teeth and plate, the teeth and plate are symmetrically arranged at the bottom of the seat fixing frame, the T-shaped positioning slider is symmetrically fixedly connected to the edges of the bottom of the seat fixing frame, and T-shaped grooves are symmetrically opened on both sides of the top of the fixing plate.

[0010] Furthermore, the T-shaped positioning slider is slidably connected to the inside of the T-shaped groove, the seat fixing frame is slidably connected to the top of the fixing plate through the T-shaped positioning slider and the toothed plate, and a seat cushion is fixedly connected to the top of the seat fixing frame.

[0011] Furthermore, a servo motor is fixedly connected to one side of the outer surface of the seat fixing frame, a rotating shaft is fixedly connected to the output end of the servo motor, a seat back is fixedly connected to the outer surface of the rotating shaft, and the seat back is rotatably connected to the seat fixing frame through the rotating shaft.

[0012] Furthermore, the lower limb training mechanism also includes a connecting plate fixedly connected to one side of the top of the support base, a rotating meniscus fixedly connected to the top of the connecting plate, the bottom of the rotating support column rotatably connected to the inside of the rotating meniscus, and one end of the telescopic spring fixedly connected to the outer surface of the rotating support column.

[0013] Furthermore, the other end of the telescopic spring is fixedly connected to a connecting steel shaft, one end of the connecting steel shaft is fixedly connected to the outer surface of the seat back, and foot pedals are symmetrically fixedly connected to the top of the rotating support column, and restraint straps are symmetrically fixedly connected to the outer surface of the symmetrically arranged foot pedals.

[0014] Furthermore, the upper limb training mechanism includes a support frame fixedly connected to the other side of the top of the support base. A training spring is fixedly connected to the top wall of the support frame, a support plate is fixedly connected to the bottom of the training spring, and pull rings are symmetrically fixedly connected to the bottom of the support plate.

[0015] This invention also discloses an exercise method for a spinal cord injury rehabilitation exercise device, the exercise method comprising: S1: Before use, medical staff will adjust the equipment parameters in advance according to the height, lower limb length and spinal injury condition of the spinal cord injury patient; S2: After starting the equipment, first control the roller rotation transmission device to complete the fine adjustment of the seat position to match the patient's lower limb size. Then start the servo motor to drive the seat back to flip backward and adjust to the best backward tilt angle suitable for the patient's spinal rehabilitation. S3: During the entire process of the seat back tilting and rotating, the patient swings back and forth in sync with the rhythm of the seat back flipping, thereby driving the patient's lower limbs to follow the device to complete passive knee flexion and extension rehabilitation exercises. The patient can hold the bottom pull ring with both hands to complete the active pull-down and relaxation reciprocating training of the upper limbs, and simultaneously exercise the upper limb muscles, shoulder and elbow joints and forearm muscle groups. S4: After training, control the servo motor to reset, the seat back returns to an upright position, the telescopic spring rebounds and drives the lower limb training mechanism to reset, and the restraint straps can be loosened to allow the patient to leave the equipment.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, a gear and rack transmission structure is formed by a meshing plate, a T-shaped positioning slider, and a transmission gear. With the help of a T-shaped sliding groove for limiting and guiding, the front and back positions of the seat can be smoothly adjusted. At the same time, the seat back can be adjusted to multiple angles by a servo motor. The sitting posture and backrest angle can be adjusted according to the patient's height, the location of the spinal injury, and the stage of rehabilitation. It can accurately conform to the physiological curvature of the human spine. The three major functions of spinal posture adjustment, lower limb passive training, and upper limb resistance stretching are integrated into the same support base. One device can complete the synchronous rehabilitation training of multiple parts of the patient's waist, back, upper limbs, and lower limbs, simplifying the rehabilitation process, reducing the space occupied by the equipment, and the overall structure has a high degree of automation.

[0017] 2. In this invention, the mechanical linkage between the seat back and the lower limb training mechanism is achieved by setting up a telescopic spring, restraint straps and pull rings, relying on the telescopic spring and connecting steel shaft. While the backrest angle is adjusted, the lower limbs are passively swung, simulating the human body's daily sitting posture of leaning back and continuous lower limb flexion and extension movement pattern. The lower limb training uses a telescopic spring as a linkage buffer component, while the upper limb training relies on the training spring to provide flexible tensile resistance. There is no hard mechanical impact force throughout the process. At the same time, the foot pedal is equipped with restraint straps to firmly fix the patient's feet and prevent limb slippage and displacement. Attached Figure Description

[0020] Please see Figure 1-6 The present invention provides a technical solution: a spinal cord injury rehabilitation exercise device, including a support base 1, a spinal seat adjustment mechanism 2, a lower limb training mechanism 3 and an upper limb training mechanism 4. The spinal seat adjustment mechanism 2, the lower limb training mechanism 3 and the upper limb training mechanism 4 are fixedly connected to the top of the support base 1, and the lower limb training mechanism 3 and the upper limb training mechanism 4 are symmetrically fixedly connected to both sides of the top of the support base 1.

[0021] The specific setup and function of its spinal chair adjustment mechanism 2, lower limb training mechanism 3, and upper limb training mechanism 4 will be explained below.

[0022] In this embodiment: the spinal seat adjustment mechanism 2 includes a roller rotation transmission device 21, a toothed plate 22 and a T-shaped positioning slider 23, and the lower limb training mechanism 3 includes a telescopic spring 31 and a rotating support column 32.

[0023] The spinal seat adjustment mechanism 2 also includes seat support frames 24 that are symmetrically fixedly connected to the top two sides of the support base 1. A fixed plate 25 is fixedly connected inside the symmetrically arranged seat support frames 24. A roller rotation transmission device 21 is fixedly connected inside the fixed plate 25. A transmission gear 26 is symmetrically fixedly connected to the outer surface of the roller rotation transmission device 21. The symmetrically arranged transmission gear 26 and the tooth plate 22 are mutually toothed and connected.

[0024] The effect achieved by the above components is as follows: the seat support frame 24 and the fixed plate 25 form a stable bottom support base, providing stable support for the entire seat adjustment structure. The roller rotation transmission device 21 drives the transmission gears 26 on both sides to rotate synchronously. The meshing transmission structure of the gears and the tooth plate 22 converts the rotational motion of the roller into the linear reciprocating motion of the tooth plate 22, providing a stable and synchronous power source for the front and rear displacement adjustment of the seat, ensuring that the force on the left and right sides of the seat is even and avoiding unilateral deviation and jamming.

[0025] Specifically, the top of the toothed plate 22 is fixedly connected to the seat fixing frame 27, the toothed plate 22 is symmetrically arranged at the bottom of the seat fixing frame 27, the T-shaped positioning slider 23 is symmetrically fixedly connected to the edges of the bottom of the seat fixing frame 27, and the top of the fixing plate 25 is symmetrically provided with T-shaped grooves 28 on both sides.

[0026] The effects achieved by the above components are as follows: the symmetrically arranged teeth and plates 22 can synchronously drive the seat fixing frame 27 to move smoothly, improving the overall stability of the seat during movement; with the matching T-shaped positioning sliders 23 and T-shaped slides 28, the movement trajectory of the seat fixing frame 27 is rigidly limited, preventing the seat from swaying left and right or tilting up and down during the forward and backward sliding process, thus improving the running accuracy and structural safety during the seat adjustment process.

[0027] Specifically, the T-shaped positioning slider 23 is slidably connected to the inside of the T-shaped slide groove 28, the seat fixing frame 27 is slidably connected to the top of the fixing plate 25 through the T-shaped positioning slider 23 and the toothed plate 22, and the seat cushion 29 is fixedly connected to the top of the seat fixing frame 27.

[0028] The effects achieved by the above components are as follows: the sliding cooperation between the T-shaped slider and the slide groove further reduces the frictional resistance when the seat moves, making the seat adjustment process smoother and quieter; the seat cushion 29 conforms to the curve of the human buttocks and is made of soft cushioning material, which can distribute the pressure of prolonged sitting, adapt to the weak back and buttocks of patients with spinal cord injury, improve the sitting comfort throughout the rehabilitation training, and at the same time avoid the discomfort caused by the pressure of hard seats on the patient's body.

[0029] Specifically, a servo motor 291 is fixedly connected to one side of the outer surface of the seat fixing frame 27, and a rotating shaft 292 is fixedly connected to the output end of the servo motor 291. A seat back 293 is fixedly connected to the outer surface of the rotating shaft 292, and the seat back 293 is rotatably connected to the seat fixing frame 27 through the rotating shaft 292.

[0030] The effects achieved by the above components are as follows: the servo motor 291 can achieve precise angle start and stop and speed control, and can steplessly adjust the reclining angle of the seat back 293. The angle adjustment is highly accurate and the start and stop are shock-free. The seat back 293 can be smoothly flipped through the rotating shaft 292. It can freely switch between various postures such as upright sitting posture, slight reclining relaxation, and large-angle lumbar traction according to the patient's rehabilitation stage and the location of spinal injury. It can specifically correct the patient's spinal deformity, relax the stiff muscles of the waist and back, and adapt to the usage needs of patients with different rehabilitation levels.

[0031] Specifically, the lower limb training mechanism 3 also includes a connecting plate 33 fixedly connected to one side of the top of the support base 1. A rotating meniscus 34 is fixedly connected to the top of the connecting plate 33. The bottom of the rotating support column 32 is rotatably connected to the inside of the rotating meniscus 34. One end of the telescopic spring 31 is fixedly connected to the outer surface of the rotating support column 32.

[0032] The effects achieved by the above components are as follows: the connecting plate 33 and the rotating meniscus 34 form the rotation fulcrum for lower limb training, restricting the rotating support column 32 to swing back and forth only along the flexion and extension direction of the human lower limb, eliminating the left and right deviation of the lower limb, conforming to the normal movement trajectory of the human knee and ankle joints, and the telescopic spring 31, as a flexible linkage component, transmits the traction force of the seat back 293 on the one hand, and buffers the impact force generated by mechanical movement on the other hand, avoiding hard traction damage to the patient's lower limb joints.

[0033] Specifically, the other end of the telescopic spring 31 is fixedly connected to a connecting steel shaft 35, one end of the connecting steel shaft 35 is fixedly connected to the outer surface of the seat back 293, and the top of the rotating support column 32 is symmetrically fixedly connected to a foot pedal 36, and the outer surface of the symmetrically arranged foot pedal 36 is symmetrically fixedly connected to a restraint strap 37.

[0034] The effects achieved by the above components are as follows: the rigid linkage between the seat back 293 and the lower limb training mechanism 3 is realized by connecting the steel shaft 35, so that the angle adjustment of the seat back 293 can simultaneously drive the passive flexion and extension of the lower limbs, realizing the integrated and synchronous implementation of lumbar and back correction training and lower limb rehabilitation training. The foot pedal 36 supports the patient's feet, and the restraint straps 37 firmly fix the patient's feet. In response to the problem of insufficient lower limb muscle strength and inability to control the feet voluntarily, the foot slippage and limb dislocation during training are prevented, ensuring that the passive lower limb training is safe and controllable throughout the entire process.

[0035] Specifically, the upper limb training mechanism 4 includes a support frame 41 fixedly connected to the other side of the top of the support base 1. A training spring 42 is fixedly connected to the inner top wall of the support frame 41. A support plate 43 is fixedly connected to the bottom of the training spring 42. Pull rings 44 are symmetrically fixedly connected to the bottom of the support plate 43.

[0036] The effects achieved by the above components are as follows: the support frame 41 provides stable vertical support for the upper limb stretching structure, ensuring that the overall upper limb training structure does not deform under stress; the training spring 42 provides adaptive stretching resistance, which increases with the patient's stretching force, thus meeting the training needs of the patient's gradual recovery of upper limb muscle strength; the support plate 43 disperses the tension and avoids stress concentration; and the symmetrically arranged pull rings 44 conform to the human hand gripping habits, making it convenient for the patient to independently complete active upper limb stretching training and exercise the upper limb muscle groups and shoulder and neck joint mobility. Example

[0037] Based on the spinal cord injury rehabilitation exercise device of Embodiment 1, this embodiment also provides a corresponding exercise method, as follows: Before use, medical staff pre-adjust the equipment parameters according to the patient's height, lower limb length, and spinal injury condition. The patient sits steadily on the seat cushion 29, places both feet on the surface of the foot pedals 36 on both sides, and tightens the restraint straps 37 to fix the feet, ensuring that the lower limbs are fully in contact with the training device.

[0038] After starting the equipment, the roller rotation transmission device 21 is first controlled to operate, which drives the transmission gears 26 on both sides to rotate synchronously. Through the meshing of the gears and the tooth plate 22, the seat fixing frame 27 is driven to slide back and forth along the T-shaped slide groove 28 to complete the fine adjustment of the seat position to match the size of the patient's lower limbs. Then, the servo motor 291 is started. The servo motor 291 drives the rotating shaft 292 to rotate at a constant speed, driving the seat back 293 to flip backward and adjust to the optimal backward tilt angle suitable for the patient's spinal rehabilitation.

[0039] Throughout the entire process of the seat back 293 tilting and rotating, the seat back 293 continuously pulls the telescopic spring 31 through the connecting steel shaft 35. The telescopic spring 31 deforms under force and drives the rotating support column 32 to swing back and forth synchronously with the rotating meniscus 34 as the fulcrum, following the rotation rhythm of the seat back 293. This causes the patient's lower limbs to follow the device to complete passive knee flexion and extension rehabilitation exercises. The entire process relies on spring cushioning, without hard mechanical impact, protecting the patient's fragile lower limb joints. At the same time, the patient can independently hold the bottom pull ring 44 with both hands and pull down the support bending plate 43 to overcome the elasticity of the training spring 42, completing the active pull-down and relaxation reciprocating training of the upper limbs, and simultaneously exercising the upper limb muscles, shoulder and elbow joints, and forearm muscle groups.

[0040] After training, the servo motor 291 resets, the seat back 293 returns to an upright position, the telescopic spring 31 rebounds and drives the lower limb training mechanism 3 to reset, and the restraint straps 37 are released to allow the patient to leave the device. The entire device relies on a mechanical linkage structure, eliminating the need for multiple independent drive sources, and can simultaneously complete three training programs: spinal posture correction, passive lower limb rehabilitation, and active upper limb stretching. It is simple to operate and suitable for both mass rehabilitation training in hospital rehabilitation departments and individual self-rehabilitation at home.
