Arm supporting mechanism of hand wrist joint rehabilitation training device

Abstract

The invention discloses an arm supporting mechanism of a hand wrist joint rehabilitation training device. The arm supporting mechanism comprises an arm bearing plate, wherein a height adjusting deviceis arranged below the arm bearing plate; a supporting plate is arranged between the height adjusting device and the arm beraing plate, and is fixedly connected to an output shaft of the height adjusting device; the arm bearing plate is divided into a first arm bearing plate and a second arm bearing plate; the first and second arm bearing plates are arranged on the supporting plate in parallel, and can slide linearly along the supporting plate to adjust the arm bearing length and height conveniently so as to fit different arm lengths and arm thicknesses of different patients, so that the beraing comfort is improved; the arm bearing mechanism is provided with a positioning beam emitter assisting the arm beraing mechanism to adjust height, so that the arm bearing height can be adjusted conveniently according to assisting beams.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an arm supporting mechanism of a wrist joint rehabilitation training device. Background technique [0002] In the existing wrist joint rehabilitation trainer, the arm support plate lacks the standard of adjustment reference when it is manually adjusted in the height direction, resulting in blind adjustment. Only by naked eye observation, each adjustment is random. If it is aligned with the power axis If it is not good, it can lead to poor rehabilitation effect and even cause excessive tension or pressure on the wrist joint; when tension or pressure is too large, because the arm is bound to the support, the arm cannot release the tension or pressure by moving back and forth in time , And it is very easy to cause secondary damage to the wrist joint. [0003] In addition, for the same patient, it needs to be readjusted every time it is used, and multiple adjustm...

[0002] In the existing wrist joint rehabilitation trainer, the arm support plate lacks the standard of adjustment reference when it is manually adjusted in the height direction, resulting in blind adjustment. Only by naked eye observation, each adjustment is random. If it is aligned with the power axis If it is not good, it can lead to poor rehabilitation effect and even cause excessive tension or pressure on the wrist joint; when tension or pressure is too large, because the arm is bound to the support, the arm cannot release the tension or pressure by moving back and forth in time , and it is very easy to cause secondary damage to the wrist joint

[0003] In addition, for the same patient, it needs to be readjusted every time it is used. Multiple adjustments are cumbersome and time-consuming, which affects user experience

In addition, the length of the arm support plate is fixed, which cannot meet the requirements of different arm lengths of different patients, resulting in uncomfortable arm support. The comfort of the end of the forearm is poor, it is too short and it is easy to compensate during the training process and affect the rehabilitation effect
