Electrically powered wheelchair device with rehabilitation mechanical arm

Abstract

The invention relates to an electrically powered wheelchair device with a rehabilitation mechanical arm, which belongs to the technical field of rehabilitation engineering. The electrically powered wheelchair device with a rehabilitation mechanical arm comprises an electrically powered wheelchair, a control and drive mechanism, an installing frame and a mechanical arm, wherein the installing frame is arranged at the rear part of the electrically powered wheelchair, the mechanical arm is connected with the installing frame, the control and drive mechanism is arranged at the bottom of the electrically powered wheelchair and is respectively connected with the electrically powered wheelchair, the installing frame and the mechanical arm to output control and drive signals. Under a passive exercise mode, an electric motor is used for outputting a driving moment to drive affected limbs of a patient to simulate and complete daily actions, and the electrically powered wheelchair device is mainly used for a beginning rehabilitation period of the patient; under an active exercise mode, the patient depends on self power to realize joint motions of upper limbs, the mechanical arm is used for monitoring the motion parameters of upper limbs in accompany motion to play a protecting function for the patient, and the electrically powered wheelchair device is mainly used for a later period of the rehabilitation exercise; under an assistant exercise mode, the electrically powered wheelchair device can be used for analyzing patient motion intention by analyzing the actions of the affected limbs, and the mechanical arm is used for realizing the motion of in an intention direction and assisting the patient to complete relative exercise actions.

Description

technical field [0001] The invention relates to a mechanical device in the technical field of rehabilitation engineering, in particular to an electric wheelchair device with a rehabilitation mechanical arm. technical background [0002] At present, there are 8.77 million patients with limb dysfunction caused by stroke, spinal cord injury and various accidents in my country, and more than half of them can improve their limb function through training. Compared with the rehabilitation of the lower limbs, since the upper limbs of the human body are mainly flexible, coordinated and skilled movements, once upper limb dysfunction occurs, it is difficult to obtain compensation, and the insufficient amount of exercise and stimulation leads to a significantly slower recovery speed than the recovery speed of the lower limbs. Therefore, rehabilitation training is particularly important for the recovery of upper limb function. The purpose of upper limb rehabilitation training is to promo...
