[0002] Parkinson's hand tremor is an extrapyramidal symptom caused by Parkinson's disease. Parkinson's disease is a degenerative disease of the central nervous system. It is a progressive disease that mainly affects the extrapyramidal system. Early patients may present with resting tremor. Most tremors begin in the distal part of one upper limb and can gradually spread to the ipsilateral lower limb, the contralateral upper limb, and the lower limb. The tremor is mainly manifested as regular movements from the thumb to the palm and finger flexion. The amplitude of the tremor is generally coarse tremor, which is usually obvious at rest, aggravated by mental stress, reduced during voluntary movement, and disappears during sleep. Mild patients will only experience tremors when they are emotionally excited, anxious, excited, or walking. The tremors of late-stage patients become frequent tremors that cannot be reduced or stopped even during voluntary movements. In order to reduce the tremors in the hands of Parkinson's patients, special rehabilitation training devices are needed. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 、 Figure 2 and Figure 3 A rehabilitation training device for alleviating hand tremors in Parkinson's patients comprises an elastic rubber head 1 with a built-in storage chamber 2 and a mounting notch 3 provided at the bottom of the elastic rubber head 1. In order to achieve an elastic damping effect, the elastic rubber head 1 needs to be a spherical structure made of a material with elastic ductility. When the patient holds the elastic rubber head 1, he can control his fingers to apply grip force to the elastic rubber head 1, thereby exercising his finger control ability.

[0022] To improve finger flexibility, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, it is necessary to set up an elastic buffer structure 4, which is internally provided with an arc-shaped embedded plate 43 embedded near the installation notch 3, a component active chamber 45 connected to the built-in storage chamber 2 and located below the arc-shaped embedded plate 43, a piston plate 47 located inside the component active chamber 45 and capable of axially moving along the component active chamber 45, a coil spring 48 placed at the bottom of the piston plate 47 and generating an upward elastic pressure on the piston plate 47, and a buffer solution filled in the area between the built-in storage chamber 2 and the upper surface of the piston plate 47. The patient holds the elastic rubber head 1 and controls the grip of the fingers and palms on the elastic rubber head 1 to change the shape of the elastic rubber head 1 at will. At the same time, when the pressure of the elastic rubber head 1 is greater than the elastic strength of the coil spring 48, the piston plate 47 can be moved downward, and the coil spring 48 can provide an elastic damping effect. By controlling the control ability of the fingers and palms on the elastic rubber head 1, the training purpose is achieved.

[0023] For the specific structure of the elastic buffer structure 4, please refer to Figure 4 and Figure 5 , including an upper cylindrical hollow shell 41, the bottom of the upper cylindrical hollow shell 41 is provided with a No. 1 fixed plate 42 with an integral structure therewith, the top of the upper cylindrical hollow shell 41 is provided with an arc-shaped embedded plate 43 with an integral structure therewith, the edge of the arc-shaped embedded plate 43 is provided with an annular embedded groove 44 with an inward concave structure, the interior of the upper cylindrical hollow shell 41 is provided with a No. 1 component active cavity 45, the center of the arc-shaped embedded plate 43 is provided with a medium flow hole 46 connecting the space above it and the top of the No. 1 component active cavity 45, the upper cylindrical hollow shell 41 is provided with a piston plate 47 capable of axial movement along the No. 1 component active cavity 45, and a coil spring 48 is provided at the bottom of the piston plate 47. In order to have an elastic function, it is necessary to make the initial length of the coil spring 48 greater than the depth of the No. 1 component active cavity 45, and the mounting notch 3 of the elastic rubber head 1 is embedded in the inside of the annular embedded groove 44.

[0024] To simulate the jitter effect and thus enhance the training of the hands, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7, it is necessary to set up an eccentric shaking mechanism 5, which is internally provided with an eccentric rotating column 57 installed below the active cavity 45 of component No. 1 and which can produce a shaking effect when rotating, and a driving motor 55 installed below the eccentric rotating column 57 and which can drive the eccentric rotating column 57 to rotate. When the driving motor 55 is started, the rotor 59 will drive the eccentric rotating column 57 to rotate rapidly. Since the center of gravity of the eccentric rotating column 57 deviates from the axis of the lower cylindrical hollow shell 51, the rotation of the eccentric rotating column 57 will drive the entire device to shake, so as to achieve a simulated shaking effect, thereby enhancing the training ability of the hands.

[0025] For the specific structure of the eccentric shaking mechanism 5, please refer to Figure 6 and Figure 7 , including a lower cylindrical hollow shell 51, the top of the lower cylindrical hollow shell 51 is provided with a No. 2 fixing plate 52 which is an integral structure with it and fixedly installed on the bottom of the No. 1 fixing plate 42, the bottom end of the lower cylindrical hollow shell 51 is provided with a No. 3 fixing plate 53 which is an integral structure with it, and the interior of the lower cylindrical hollow shell 51 is provided with a No. 2 component movable cavity 56, the lower cylindrical hollow shell 51 is provided with a rotatable rotating shaft 58 through bearings at the top and bottom ends of the No. 2 component movable cavity 56, an eccentric rotating column 57 is installed between the two rotating shafts 58, and a driving motor 55 is fixedly installed on the bottom end of the No. 3 fixing plate 53 through a motor fixing shell 54, and the rotor 59 of the driving motor 55 is docked with the rotating shaft 58 at the bottom.

[0026] During use, the patient holds the elastic rubber head 1 and controls the grip of the fingers and palm on the elastic rubber head 1, so as to change the shape of the elastic rubber head 1 at will. At the same time, when the pressure of the elastic rubber head 1 is greater than the elastic strength of the coil spring 48, the piston plate 47 can be moved downward, and the coil spring 48 can provide an elastic damping effect. By controlling the control ability of the fingers and palm on the elastic rubber head 1, the training purpose is achieved. The drive motor 55 is started, and the rotor 59 drives the eccentric rotating column 57 to rotate rapidly. Since the center of gravity of the eccentric rotating column 57 deviates from the axis of the lower cylindrical hollow shell 51, the rotation of the eccentric rotating column 57 will drive the entire device to shake, so as to achieve a simulated shaking effect, thereby enhancing the training ability of the hand.
