Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and in particular to the technical field of a limb rehabilitation exercise device. Background Technology

[0002] Paralysis refers to the complete or incomplete loss of motor ability of a part of the body due to nerve dysfunction. It can be divided into facial paralysis, monoplegia (paralysis of one upper or lower limb), hemiplegia, paraplegia, quadriplegia, etc. Rehabilitation equipment is essential in the nursing process of paralyzed patients. It mainly helps patients to carry out passive movement and daily activities.

[0003] A limb rehabilitation assistive training device, application (patent) number CN201921742174.X, comprises a first motor that drives a lead screw to rotate via a reducer, transmission shaft, and coupling. The lead screw drives a moving block to move left and right. The bottom end of the moving block drives a slider to slide left and right on the top of a guide rail. Simultaneously, the top end of the moving block drives a first support rod to move left and right. The first support rod, through an adjustment device, a second support rod, and a fixing block, drives the lower side of a rotating plate to move left and right, thereby facilitating the bending and running of a human leg resting on the right end of the rotating plate. Its main function is to achieve passive limb lifting training through mechanical support. The device is rather simple and can only perform basic lifting movements, resulting in poor training effectiveness. Furthermore, the adjustment device includes two sets of screws and an adjustment rod. The outer ends of the two sets of screws are rotatably connected to the top of the first support rod and the left end of the second support rod, respectively. The middle of the adjustment rod has a second threaded hole that runs through it from left to right. The inner ends of the two sets of screws pass through the left and right ends of the adjustment rod and are screwed into the left and right sides of the threaded hole, respectively. Rotating the adjustment rod allows for easy adjustment of the extension length of the two sets of screws on the adjustment rod, thus facilitating the adjustment of the overall length of the adjustment device. However, hemiplegic patients cannot adjust this themselves according to their own condition, making it inconvenient to use. Summary of the Invention

Both ends of the rack 73 are provided with support plates 77, and each support plate 77 is provided with several fixing straps II 78. This mechanism is easy to operate, and patients can control the swing of their legs in real time to prevent discomfort caused by high swing. It can also realize horizontal swing exercise of both legs.

[0025] Both ends of the rack 73 are provided with grooved parts 79, and each grooved part 79 is rotatably provided with a connecting body 710. The connecting body 710 is rotatably connected to the corresponding support plate 77, which can fold the support plate 77 to reduce interference.

[0026] The upper end of the boom 71 is provided with a slide 711, which is slidably engaged with the guide rail 712 provided on the boom 2. The slide 711 is provided with a threaded hand-tightening locking bolt 713 for fixed connection with the guide rail 712.

[0027] The working process of this invention: In operation, the limb rehabilitation exercise device of the present invention loosens the hand-tightening fixing bolt 13 and slides the corresponding guide rope assembly 4 to adjust it to the required position. Then, the hand-tightening fixing bolt 13 is tightened, and the foot fixing mechanism 3 is fixed on the corresponding foot of the patient. Then, the patient holds the handle I633 and rotates the turntable I632 forward. The turntable I632 drives the winding disc 64 to rotate and wind the rope 65 through the worm gear pair 631. The winding rope 65 pulls the pull wheel 66 downward through the movable pulley group 61. The pull wheel 66 pulls the pull rope 5 downward. The pull rope 5 pulls the patient's leg to extend and lift through the foot fixing mechanism 3. When the patient's leg is lifted to its limit, the patient holds the handle I633 and rotates the turntable I632 backward. The turntable I632 drives the winding disc 64 to rotate and unwind the rope 65 through the worm gear pair 631. At this time, the patient's leg descends back to its original position. The above operation is repeated to achieve repeated extension and lifting movements of the patient's leg.

[0028] When the patient's leg needs to swing horizontally, with the leg raised, loosen the hand-tightening locking bolt 713, then slide the horizontal drive mechanism 7 so that the corresponding support plate 77 enters the corresponding knee joint of the leg, and then fix it with the fixing strap II 78. Then remove the hanging ring 33 from the hook 9, then hold the handle II 76 and rotate the turntable II 75 alternately clockwise and counterclockwise. The turntable II 75 drives the rotating shaft 74 to rotate, and the rotating shaft 74 drives the rack 73 to slide back and forth. The rack 73 drives the patient's leg to swing horizontally through the support plate 77.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
