Description

Wrist rehabilitation device

The present invention relates to a wrist rehabilitation device, and more particularly to a wrist rehabilitation device that can perform rehabilitation training for a wrist.

According to the Patent No. M333178 of the Republic of China, the "Upper Limb Passive Joint Rehabilitation Machine" patent discloses a conventional hand rehabilitation device having a support frame and a driving device. The support frame is composed of a base and a trunk. The main body is erected on the base and coupled with a sliding seat. The sliding seat can be vertically lifted on the main body, and a positioning rod is respectively arranged on the upper and lower ends of the sliding seat. The first end of the sliding seat is provided with a rotating shaft, and a first bracket is connected to the rotating shaft. The front end of the first bracket is telescopic and is provided with a grip group capable of freely rotating; a second bracket that is translatable and horizontally rotatable. The driving device comprises a motor, a speed reducer, a pulley block and a rope; the motor is arranged on the sliding seat, the speed reducer is coupled with the motor and is provided with a winch, the pulley block is composed of a plurality of pulleys, the plurality of pulleys Separatingly disposed on the positioning rod, the sliding seat and the first bracket; the rope is wound around the pulley block and the winch, and the two ends of the rope are fixed to the first bracket to pull the first bracket when the motor is operated Rotate. Accordingly, the hand rehabilitation device can provide the user with rehabilitation training for the wrist, elbow or shoulder.

Please refer to FIG. 1 , which discloses a use situation in which the user operates the hand rehabilitation device for wrist rehabilitation training. The user can place the forearm on the tray 911 of the second bracket 91 and position the forearm through the strap 912 of the second bracket 91 while the user's fingers abut against the grip set 92. When the first bracket 93 is rotated by a moving angle θ1, the grip group 92 is rotated by a correction angle θ2, thereby causing the user's wrist to rotate to achieve a rehabilitation effect.

However, the conventional hand rehabilitation device needs to drive the rope to drive the rope and pass through a plurality of pulleys disposed on the positioning rod, the sliding seat and the first bracket to indirectly pull the first bracket to rotate. And the grip group supporting the finger is freely swivel relative to the first bracket, so it is not easy to accurately control the angle of the wrist flexion and the extension, so that the conventional hand rehabilitation device The healing effect is limited.

In addition, the conventional hand rehabilitation device is large in size and complicated in structure, and is not only complicated in structure but also easy to operate, and the manufacturing, carrying and assembling costs of the hand rehabilitation device are both high, and the hand assembly is completed. The health device also needs to occupy a certain volume of installation space, so that the average consumer has little ability and willingness to purchase the hand rehabilitation device, so during the rehabilitation training, the user needs to frequently go to the rehabilitation site (for example, a hospital). Between the home and the home, it is very inconvenient and easy to reduce the user's willingness to rehabilitate.

In addition, the conventional hand rehabilitation device can provide rehabilitation training for the wrist, the elbow and the shoulder, etc., but the rehabilitation training can only be performed for a specific part at a time, so that many people cannot simultaneously Use a hand rehabilitation device. Therefore, for a user who only needs to perform rehabilitation training for a single part, although only some functions of the conventional hand rehabilitation device are used in rehabilitation, an entire hand rehabilitation device is still occupied. And the formation of a waste of rehabilitation resources.

Moreover, the conventional hand rehabilitation device has a complicated structure, and each component is directly exposed to exhibit the appearance of the bracket staggered and the rope is wound, which is easy to cause the user to intuitively generate repulsion, thereby reducing the user's willingness to rehabilitate.

The main object of the present invention is to provide a wrist rehabilitation device which can accurately control the degree of flexion and extension of the wrist to enhance the rehabilitation effect.
