Wrist rehabilitation training device

Abstract

The invention discloses a wrist rehabilitation training device which comprises a hand tray, a rotating shaft, a torque sensor, a motor, a base and a controller. The rotating shaft is arranged on two brackets, one end of the hand tray is fixedly connected to the rotating shaft, and the upper end face of the hand tray is provided with an elastic band for binding a patient's hand; one end of a rotaryshaft of the torque sensor is fixedly connected with the rotating shaft, and the other end is fixedly connected to a rotary shaft of the motor, the controller is respectively connected with the torque sensor and the motor through data lines, and the torque sensor detects the torque of the rotating shaft and transmits a torque value to the controller. The wrist rehabilitation training device is simple in structure, safe and practical, active and passive activity training of the wrist joint can be achieved, and the problems that wrist joint rehabilitation training devices are lacked, low in working efficiency or the devices are expensive are effectively solved.

Description

technical field [0001] The invention relates to a rehabilitation training device, in particular to a device for performing rehabilitation training on a patient's wrist joint. Background technique [0002] In the annual cerebrovascular disease patients, about 50% of the survivors left the dysfunction of the upper limbs and hands, and the wrist joints often showed a state of spasticity and flexion. At present, there are few rehabilitation training devices for the hand. Common ones include fingerboards, pneumatic gloves, elastic-assisted hand orthoses, end-traction rehabilitation robot systems, and exoskeleton rehabilitation robot systems. [0003] Devices such as fingerboards can correct the abnormal state of the hands of stroke patients and reduce the degree of spasticity of patients, but they cannot complete the correction and training of the wrist joints. The exoskeleton robot system can realize the passive and active activities of each finger and wrist, which can signific...
