Wrist joint rehabilitation training device

Abstract

The invention relates to a wrist joint rehabilitation training device which comprises two parts, namely, a rehabilitation training executive device part and a mirror image autonomous input device part. The rehabilitation training executive device part comprises a base seat, a forearm sliding chute, a forearm sliding block, a forearm height adjusting rod, a forearm supporting plate, a wrist rotating sliding rail, a wrist rotating sliding block, a wrist rotating guiding wheel, a bracket, a wrist rotating angle sensor, a wrist rotating motor, a pull rope, a wrist rotating rod, a wrist swing rod, a wrist swing angle sensor, a wrist swing motor, a wrist deflection rod, a wrist deflection sensor and a wrist deflection motor. The mirror image autonomous input device part comprises no motor, and the other devices of the mirror image autonomous input device part are symmetrical with those of the rehabilitation training executive device part. The wrist joint rehabilitation training device has three freedom degrees of rotation, swing and deflection, can achieve all the motions of a wrist joint and the rehabilitation training of composite motions through wearing for one time, and enables a rehabilitation therapist to control the wrist of a patient to carry out rehabilitation training conveniently through the mirror image autonomous input device part.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a wrist joint rehabilitation training device. Background technique [0002] Nursing of paralyzed or uncoordinated limbs due to car accidents, strokes, and other medical conditions is an increasing priority in the medical field. Traditional rehabilitation care refers to patients doing simple bending and stretching exercises under the guidance and help of medical staff, so as to gradually restore the mobility of limbs. However, this method not only consumes a lot of energy and physical strength of the nursing staff, but also accidents will inevitably occur during the exercise. In recent years, multifunctional rehabilitators designed to restore limb movement have emerged in an endless stream, which has reduced the burden of care for medical staff and patients' families to a certain extent, but the treatment effect is not satisfactory. Currently, the rehabi...

Problems solved by technology

Currently, the rehabilitators on the market generally perform exercise rehabilitation for the large joints of the limbs, and it is difficult to fully rehabilitate the wrist joints. However, some wrist rehabilitators either can achieve a single rehabilitation action or need to be replaced. Different accessories require multiple operations and adjustments to achieve different rehabilitation actions, which makes the rehabilitation process too troublesome. In addition, the setting of rehabilitation actions of this type of rehabilitation device is too complicated, the safety is low, and the efficiency of self-rehabilitation is low.

This limitation in functional operation seriously affects the rehabilitation effect, and even delays the progress of rehabilitation and causes inestimable losses.
