Auxiliary rehabilitation training device for hemiplegic finger of patient

Abstract

The invention discloses a platform type auxiliary rehabilitation training device for a hemiplegic finger of a patient. The auxiliary rehabilitation training device for the hemiplegic finger of the patient comprises a finger training mechanism, a hybrid driving mechanism, a sensing device and a control system, wherein the hybrid driving mechanism comprises a motor and a magnetorheological fluid damper, the finger training mechanism comprises a slider-crank mechanism and a finger moving device which can rotate freely and slide forwards or backwards under the driving of the slider-crank mechanism, the control system comprises an upper computer and a lower computer, the PID control algorithm is configured in the lower computer, and a virtual scene module and a virtual reality feedback force module are arranged in the upper computer. By the adoption of the auxiliary rehabilitation training device for the hemiplegic finger of the patient, combination of active training and passive training can be achieved for the patient, the mechanical structure, the hybrid driving mechanism, the sensing device and the control system cooperate with one another to achieve man-machine interaction, a training process is controlled strictly, and the interestingness of the training process is improved by the adoption of game images.

Description

technical field [0001] The invention relates to a rehabilitation training device, in particular to an auxiliary rehabilitation training device for rehabilitation training of fingers of patients with hemiplegia. Background technique [0002] The importance of hands in daily life is self-evident, but due to the particularity of the structure of the hands, the hands are easily injured, causing hand dysfunction, which brings great inconvenience to daily life. Hemiplegia refers to the movement disorder of one side of the upper and lower limbs, the facial muscles and the lower part of the tongue muscle caused by brain damage, which often leads to the stiffness of human fingers. Stiff resistance. Actively carrying out early rehabilitation training is an important link to effectively alleviate the symptoms of hemiplegic fingers, promote the recovery of finger functions, and maximize the recovery of finger motor functions. [0003] At present, rehabilitation training in hospitals i...

Problems solved by technology

[0006] Technical problem to be solved: Aiming at the deficiencies of the prior art, the present invention provides an auxiliary rehabilitation training device for the patient's hemiplegic fingers, which solves the problem that the data gloves and exoskeleton device finger rehabilitation training devices in the prior art are easy for the patient. Secondary damage is caused, and all fingers are trained together during training, which is low in pertinence, and the training mode combining active and passive training cannot be realized, the training effect is not good, and the device is expensive and other technical problems
