Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, in particular to an adjustable multi-angle limb activity rehabilitation training device and method. Background Art

[0002] With the advancement of science and technology and the improvement of living standards, many countries in the world are entering (or have already entered) an aging society. Among the elderly population, there are a large number of patients with cardiovascular and cerebrovascular diseases or neurological diseases, most of whom have symptoms of limb movement disorders such as hemiplegia. Medical theory and clinical medicine have proven that in addition to early surgical treatment and necessary drug treatment, later rehabilitation training also plays a very important role in the recovery of limb movement function. Due to the lack of professional caregivers or high medical expenses, most patients choose to conduct self-rehabilitation training at home. Due to unscientific training methods and insufficient training volume, many patients miss the best recovery time and gradually lose the function of limb movement. Therefore, appropriate and scientific limb rehabilitation training has a positive effect on the rapid healing of injuries and the promotion of functional recovery.

[0003] Chinese patent: CN117482470B discloses an adjustable limb activity rehabilitation training device, which sets a leg training component on both sides of the seat hinge, so that the leg training component is connected to the seat and can swing laterally at a certain angle, and sets a lower limb training component at the end of the leg training component, so that the lower limb training component can swing vertically at a certain angle, so that the user can perform specific lower limb exercises, and at the same time, an arm training component is hinged on the leg training component, and the arm training component rotates freely around the hinge point on the leg training component. By setting the leg training component, the lower limb training component and The arm training component allows the trainee to train both the upper and lower limbs. However, when the above-mentioned training device is in use, since the leg training component only relies on the torsion spring to provide resistance and reset force to the leg training component, and the lower limb training component and the arm training component are both arranged on the leg training component, when the user only needs to use the lower limb training component, the leg training component cannot be fixed, making it easy to shake during lower limb training, which cannot provide the user with a good training effect. At the same time, the arm training component of the above-mentioned training device can only rotate around a fixed point for training, so that multi-angle training cannot be performed when in use, resulting in poor training effect.

[0004] Based on this, an adjustable multi-angle limb activity rehabilitation training device and method are now provided, which can eliminate the disadvantages of existing devices. Summary of the Invention

At the same time, the user can also use the leg support plate 25 to make the hinge rod 18 drive the swing rod The movable rod 26 rotates in the horizontal direction to exercise the side tension. When the user's feet are inconvenient to use the foot pedal 28 for leg training, the auxiliary connecting plate 35 is rotated 90 degrees, and the user's calf is tightly attached to the inner side of the arc-shaped placement groove. When the user performs leg training and needs to fix the hinge rod 18 at a specific angle, the output end of the electric push rod 21 continues to push the friction rod 20 to move. The friction rod 20 and the first friction wheel 19 are frictionally engaged, so that the first friction wheel 19 drives the hinge rod 18 to rotate, thereby fixing the hinge rod 18 at a specific angle.

[0052] When the user needs to perform upper limb training, he pushes the sliding cover 42 to slide so that the sliding cover 42 is separated from the storage plate 41, then takes out the handle 46 and the winding box 47, pulls the handle 46, determines the length of the first traction rope according to the length of the user's upper limb, and then fixes the winding roller 48 with the third stop screw 49. According to the weight required by the user for training, the number of counterweight blocks 52 is selected. After the selection is completed, one end of the stop slide 53 is inserted into the first connecting through-hole on the counterweight block 52 of the selected weight. Then, the user pulls the counterweight connecting rod 51 through the first and second traction ropes, and the stop slide 53 drives several counterweight blocks 52 to move, thereby performing upper limb training. When it is necessary to adjust the stretching angle of the handle 46, the storage plate 41 can be rotated, and then the rotating tube 43 can be fixed by the second stop plate 58, so that multi-angle training can be performed;

[0053] When the user needs to perform a back massage to speed up blood circulation throughout the body, the motor 76 is started by controlling the external control component. The output end of the motor 76 drives the transmission belt 75 to rotate through the third friction wheel and the second friction wheel, and the transmission belt 75 drives several dial plates 73 to rotate. When the bottom end of the dial plate 73 contacts the limit column 74, the dial plate 73 drives the rotating rod 70 to rotate through the limit column 74. When the rotating rod 70 rotates, the exposed length of the massage roller 72 increases, so that the massage roller 72 massages the user's back. When the axis of the rotating rod 70 is horizontal, the limit column 74 coincides with the notch on the dial plate 73, so that the dial plate 73 disengages from the limit column 74. Under the action of the third torsion spring, the rotating rod 70 rotates to the initial position. At the same time, several dial plates 73 intermittently toggle the rotating rod 70, thereby massaging the user's back.
