Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a lower limb rehabilitation exercise device for cerebrovascular disease. Background Art

[0002] With the improvement of living standards, the incidence of cardiovascular and cerebrovascular diseases is getting higher and higher, and the patients are getting younger and younger. Cerebrovascular diseases are characterized by high incidence, high disability rate, high mortality rate and high recurrence rate. Chronic cardiovascular and cerebrovascular diseases often cause functional disorders such as hemiplegia, paraplegia, cognitive impairment, etc. If patients subsequently undergo various treatments and training measures, appropriately choose to use assistive devices, and obtain maximum daily life activities, it is entirely possible for them to re-participate in normal social life.

[0003] After treatment, patients often have sequelae. During the long recovery process, lower limb exercises can effectively promote the patient's recovery. Existing lower limb rehabilitation exercise devices mostly use pedals to assist the patient's legs to swing, but this can only assist the patient's legs to swing back and forth, and cannot assist the patient's legs to swing left and right. At the same time, the pedals are made of hard materials. When the patient exercises, the patient's legs need to be tied to the pedals, which will cause a greater sense of pressure on the patient's legs and cannot well protect the patient's legs.

[0004] Existing lower limb rehabilitation exercise devices are limited to rehabilitating the patient's legs. However, when walking, the two arms swing naturally back and forth with the body as the center, about 35 degrees forward and about 15 degrees backward. In this regard, how to coordinate the hands and feet when walking is beyond the patient's ability. Therefore, this application proposes a lower limb rehabilitation exercise device for cerebrovascular disease. Summary of the Invention

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Existing lower limb rehabilitation exercise devices are limited to the rehabilitation of patients' legs. However, when walking, the arms swing naturally back and forth with the body as the center, about 35 degrees forward and about 15 degrees backward. In this regard, how to coordinate hands and feet to walk is beyond the ability of patients.

[0036] In order to solve the defects in the prior art, this solution provides the following embodiments:

[0037] Please see the attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides a lower limb rehabilitation exercise device for cerebrovascular disease, comprising:

[0038] Bracket 3, which serves as the basic structure of the entire device and is used to provide a fixed installation location for other structures. The bottom of the bracket 3 is fixedly connected to the base 1, and the top of the base 1 is fixedly connected to the shell 11. Three steel ropes 9 are set at the bottom of the shell 11. The steel ropes 9 on both sides are cross-arranged and an X-shaped rubber sleeve 10 is set at the intersection. The bottom ends of the steel ropes 9 are fixedly connected to the elastic shoes 2;

[0039] The winding mechanism is disposed inside the housing 11 and is connected to a telescopic handle 12. The telescopic handle 12 is disposed in the middle portion of the inner side of the bracket 3. The number of the winding mechanisms corresponds to the number of the wire ropes 9. The winding mechanism includes a reel 19 for winding the wire ropes 9. The middle reel 19 is disposed in a reel cavity 20 formed inside the housing 11 via an automatic reset mechanism.

[0040] The clamping mechanism includes a support plate 6 mounted on one side of the bracket 3 by screws. The adjacent sides of the two support plates 6 are slidably connected to clamping blocks 7 for clamping the armrests on both sides of the wheelchair. The separated sides of the two support plates 6 are fixedly connected to electric push rods 4. The driving ends of the electric push rods 4 pass through the support plates 6 and are connected to the clamping blocks 7.

[0041] Power steering system, the power steering system is used to control the winding mechanism to reel in the wire rope 9 when the telescopic handle 12 moves;

[0042] The patient with cerebrovascular disease in the wheelchair moves to the platform on the top of the base 1 via the ramp 5. At this time, the electric push rod 4 is activated to drive the clamping block 7 to fix the armrests on both sides of the wheelchair, thereby stabilizing the wheelchair, so that the patient can wear the elastic shoes 2 and the clamping block 7. The patient wears the elastic shoes 2 on his feet, pulls the clamping block 7 downwards, and stands up under his own support by holding the telescopic handle 12. The telescopic handle 12 moves relative to the patient by swinging his hands. With the assistance of the power steering system, the servo motor 17 is started and stopped, and the wire rope 9 is wound and released through the reel 19. In conjunction with the conveyor 16, patients with cerebrovascular disease can perform normal walking exercises on their lower limbs, and achieve walking in the true sense with their hands and feet. After the exercise, patients with cerebrovascular disease can sit on the wheel by pressing the clamp 7 downward, and by loosening the clamp 7, the patient can move the wheelchair and leave the platform. The design is ingenious, the operation is simple and convenient, and no medical staff is required to assist, which reduces the workload of medical staff.

[0043] A slope 5 is provided on one side of the interior of the base 1, and the slope of the slope 5 is less than or equal to 10%. A conveyor 16 is fixedly connected to the other side of the interior of the base 1 for walking for cerebrovascular disease;

[0044] Slope 5 adopts a straight ramp with a slope width of not less than 1200 and a slope of not more than 1:12. The width of the ramp should not be less than 0.90m. The slope percentage calculation formula is: = (h / d) x 100, h: the height of the erection, d: the length of the horizontal plane.

[0045] A rotating rod 21 is provided inside the shell 11, one end of which is connected to the driving end of the servo motor 17. The servo motor 17 is placed inside a machine cavity 18 opened inside the shell 11, and a heat dissipation hole connected to the outside world is opened on one side of the inner wall of the machine cavity 18. The servo motor 17 is used to start and stop, and the reel 19 is used to wind and release the wire rope 9. In conjunction with the conveyor 16, patients with cerebrovascular disease can perform normal walking exercises for lower limbs. The design is ingenious, the operation is simple and convenient, and no medical staff is required to assist, which reduces the workload of medical staff.

[0046] The outer walls of the rotating rod 21 on both sides are fixedly connected to the reels 19 on both sides.

[0047] The outer wall of the middle part of the rotating rod 21 is rotatably connected to the connecting rod 22. The outer wall of the connecting rod 22 is fixedly connected to the middle reel 19. One end of the outer wall of the connecting rod 22 is located in the reset cavity and is sleeved with a reset spring 23. The reset cavity is located between the middle reel 19 and one of the side reels 19.

[0048] The servo motor 17 is used to start and stop, and the reel 19 is used to wind and release the wire rope 9. In conjunction with the conveyor 16, patients with cerebrovascular disease can perform normal walking exercises for their lower limbs. The design is ingenious, the operation is simple and convenient, and no medical staff is required to assist, which reduces the workload of medical staff.

[0049] The inner end of the reset spring 23 is connected to the outer wall of the connecting rod 22 , the outer end of the reset spring 23 is connected to the inner wall of the reset cavity, and the bottom end of the middle steel wire rope 9 is fixedly connected to the X-shaped rubber sleeve 10 .

[0050] The outer side of the X-shaped rubber sleeve 10 is fixedly connected with a safety harness 8 for wearing and supporting patients with cerebrovascular diseases, which plays a role of protection and limitation, and avoids the phenomenon of self-friction of the wire rope 9.

[0051] The top of the other side of the bracket 3 is fixedly connected to a support rod 13, and the bottom end of the support rod 13 is connected to one side of the connecting profile 15, and the connecting profile 15 and the support rod 13 are rotatably connected. A display screen 14 is installed on one side of the plane of the connecting profile 15 by screws.

[0052] The power steering system is composed of at least a mechanical steering system, a steering control valve, a steering power cylinder, a steering oil pump and a steering oil tank.

[0053] In a hydraulic power steering system, the amount of steering assist depends on the pressure acting on the steering cylinder piston. A greater steering force results in a higher hydraulic pressure. The hydraulic pressure in the steering cylinder is regulated by a steering control valve connected to the main steering shaft. The steering pump delivers hydraulic oil to the steering control valve. If the steering control valve is in the neutral position, all the hydraulic oil flows through the steering control valve, into the oil outlet, and back to the steering pump. Since almost no pressure is generated at this point, and the pressures on both ends of the steering cylinder piston are equal, the piston will not move in either direction, preventing the vehicle from steering. When a patient with cerebrovascular disease turns the telescopic handle 12 in either direction, the steering control valve moves accordingly, closing one oil circuit and opening the other circuit more, causing a change in the hydraulic oil flow rate and generating pressure. This creates a pressure differential across the steering cylinder piston, causing the piston to move toward lower pressure, forcing the hydraulic oil in the cylinder back through the steering control valve to the steering pump, reducing the driver's steering effort.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
