Universal five-finger rehabilitation training device for left and right hands

Abstract

The invention relates to a universal five-finger rehabilitation training device for left and right hands. Pneumatic fingers of a thumb, an index finger, a middle finger, a ring finger and a little finger are connected onto a support frame, an air pump is placed in the support frame and connected with a main air outlet valve through a main air delivery tube, an air cylinder air inlet hole of a ventilation valve is connected with the main air outlet valve, and five air outlet holes are connected with the pneumatic fingers of the thumb, the index finger, the middle finger, the ring finger and thelittle finger through air distributing valves, air distributing tubes and fingertip air inlet valves respectively; the fingertip air inlet valves of the pneumatic fingers are connected with near-joint air bags through rigid air guide tubes, and the rigid air guide tubes are movably connected with U-shaped buckles on a base connecting plate; and by means of re-arrangement of the five pneumatic fingers, interchange of left and right hands of a patient for separate training is realized, and the two ends of far-joint air bags are connected with near-joint fixing plates and far-joint fixing platesrespectively and connected with the near-joint air bags. By means of unitized design of fingers, cooperation with pneumatic drive and quick-connecting and quick-separating connection mode, a separatetraining mode for the left and right hands of the patient is realized by the same rehabilitation training device, so that the utilization rate of the rehabilitation device is effectively increased.

Description

technical field [0001] The invention relates to a hand rehabilitation mechanical structure, in particular to a universal rehabilitation training structure for left and right hands. Background technique [0002] Stroke is a common disease among the elderly. In recent years, with the increasingly serious problem of population aging, the number of stroke patients has increased year by year, and domestic and foreign medical resources are relatively insufficient. Relevant researchers have gradually shifted their research direction to rehabilitation training robots. The emergence of rehabilitation training robots has alleviated the problem of insufficient medical resources to a certain extent. Studies have shown that the complex and huge mechanical structure will cause a certain psychological burden on the patient, which is not conducive to the rehabilitation training of the patient. Light weight and miniaturization have become the development trend of current rehabilitation trai...

AI Technical Summary

Problems solved by technology

At present, hand rehabilitation training equipment is divided into rigid structure and flexible structure. Rigid structure can realize precise control, but generally has complex structure and large size. Flexible structure is generally designed to be wearable and small in size, but the control accuracy is not high.

Further, these two types of rehabilitation training equipment can generally only be used for rehabilitation training of unilateral hand, which limits the utilization rate of hand rehabilitation training equipment to a certain extent.
