Wrist rotation function rehabilitation training device

Abstract

The invention relates to a wrist rotation function rehabilitation training device. The cylindrical support of the training device is rotatably connected to a base and can be vertically and transversely fixed, so that the hands can be trained in a prostrate state and a horizontal state. A lead screw and a roller of a traction device of the training device form lead screw nut transmission. When themotor on the base drives the lead screw to rotate, the idler wheels not only can move circumferentially on the supporting disc, but also can move towards the center of the supporting disc along the lead screw, so that the idler wheels can drive the U-shaped brackets to move inwards or outwards spirally on the supporting disc, and the idler wheels can touch the contact switches when moving to the middle and the edges of the supporting disc. Forward and reverse rotation switching of the motor is achieved, and the U-shaped bracket reciprocates inside and outside and fast and slow alternate spiralmotion provide traction force for a conical sleeve. The device can carry out automatic rehabilitation training on the hands of a patient, extra personnel assistance is not needed, the training diversity is improved, the rehabilitation training effect is good, and the rehabilitation process can be greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of limb rehabilitation equipment, in particular to a wrist pronation function [0002] Rehabilitation trainer. Background technique [0003] Stroke, known as cerebrovascular disease in modern medicine, is a common and frequently-occurring disease of the nervous system. Its mortality rate is high, accounting for about 10% of all disease deaths. It is one of the three major diseases that seriously endanger human health; With the improvement of stroke diagnosis and rescue level in modern medicine, the mortality rate of stroke patients has dropped significantly, but the disability rate has increased significantly. About 75% of stroke patients will leave sequelae of different degrees in the later stage of the onset, such as hemiplegia , language barrier, limb pain, etc., the highest incidence of hemiplegia. [0004] In the rehabilitation of hemiplegia, the recovery of hand function is the most difficult. The pa...

Problems solved by technology

[0005] However, because the patient's hand is in a convulsive state of drooping and flexing, and lacks voluntary grip, it is difficult to independently hold the handle of the tight linkage mechanism for continuous training, which often requires the help of rehabilitation personnel to complete, resulting in the patient's rehabilitation training The process is slow and the effect is not good, so it is necessary to design a training device that can effectively restrain the spastic hand swing and has a high degree of automation to solve the above problems
