A passive finger rehabilitation training device

Abstract

The invention provides a passive finger rehabilitation training device. The device comprises a connecting frame, a servo motor is fixed to the connecting frame, an output shaft of the servo motor is fixedly connected with the rear end of a first connecting rod and a first gear, a first pin shaft is fixed to the connecting frame, and the first pin shaft is rotationally connected with a first duplexgear and the rear end of a second connecting rod; a third pin shaft is rotationally connected with the left end of a third connecting rod and the front end of the first connecting rod and is fixedlyconnected with the rear end of a fourth connecting rod and a second gear; a second pin shaft is rotationally connected with the right end of the third connecting rod, the rear end of a fifth connecting rod, the front end of the second connecting rod and a triplex gear; a fifth pin shaft is fixedly connected with the rear end of a swing rod and a third gear and is rotationally connected with the left end of a sixth connecting rod and the front portion of the fourth connecting rod; a fourth pin shaft is rotationally connected with a second duplex gear, the right end of the sixth connecting rod and the front portion of the fifth connecting rod; the first gear is meshed with a fourth gear of the first duplex gear, the triplex gear is in belt transmission with the first duplex gear and a secondduplex gear, a fifth gear of the triplex is meshed with the second gear, a sixth gear of the second duplex gear is meshed with the third gear, and the device and four fingers of a patient are consistent in flexion-extension track.

Description

Technical field [0001] The invention relates to a passive finger rehabilitation training device, which belongs to the field of rehabilitation medical equipment. Background technique [0002] At present, the trend of population aging in our country is obvious. The number of patients with stroke and hemiplegia is increasing year by year. At the same time, the pace of life is accelerating, environmental pollution and other factors have caused more and more patients with hand motor dysfunction. The hand is an important organ of human body movement, and hand rehabilitation needs. A long-term rehabilitation process, and the usual hand rehabilitation training device is mostly a structure of a motor and a drive rod, which has a certain gap with the flexion and extension motion trajectory of the patient’s fingers. Rehabilitation training cannot be carried out according to the motion trajectory of a healthy person’s finger. The effect has a certain impact. [0003] The application adopts a ...

[0002] At present, the population aging trend in my country is obvious. The number of patients with stroke and hemiplegia is increasing year by year. At the same time, due to factors such as the accelerated pace of life and environmental pollution, more and more patients have hand motor dysfunction. The hand is an important movement organ of the human body, and hand rehabilitation needs It takes a long time for the rehabilitation process, and the usual hand rehabilitation training device is mostly a motor plus a drive rod structure, which has a certain gap with the flexion and extension movement trajectory of the patient's fingers, and cannot perform rehabilitation training according to the movement trajectory of healthy people's fingers. has a certain effect
