Finger movement function rehabilitation training device

Abstract

The invention discloses a finger movement function rehabilitation training device which comprises a supporting seat and a finger training mechanism arranged on the supporting seat. The finger training mechanism consists of a finger motion mechanism and a hybrid driving and sensing mechanism, wherein the finger motion mechanism comprises a driving rod, a driving connection rod, a front-rear-end connecting rod, a front-end connecting rod, a front-end finger sleeve, a rear-end finger sleeve and a fixing seat. One end of the driving rod is fixedly connected with a driving shaft, the fixing seat is fixe to the supporting seat, one end of the front-rear-end connecting rod is rotatably connected to the fixing seat, the other end of the front-rear-end connecting rod is rotatably connected with the front-end connecting rod, one end of the driving connection rod is rotatably connected to the middle of the front-rear-end connecting rod, and the other end of the driving connection rod is rotatably connected with the other end of the driving rod. The finger motion mechanism can accurately control movements of all joints of fingers, enables a hemiplegic patient to perform training in a correct finger movement mode and facilitates rehabilitation of normal movement functions of the fingers of the patient.

Description

technical field [0001] The invention relates to the field of finger rehabilitation training, in particular to a motor function rehabilitation training device for fingers of hemiplegic patients. technical background [0002] The hand is an important tool for human beings to experience and change the world, and it is also the most delicate tool for human beings to survive. Human's daily life is inseparable from the movement of human hands, and human hands are the most dexterous part of the human body and the most prone to dysfunction. When stroke patients suffer from hemiplegia, hand motor function is often severely damaged, which brings a lot of inconvenience to the patient's life. In addition, the loss of hand function also causes serious damage to the patient's spirit. [0003] At present, most of the rehabilitation training for hemiplegic patients is completed under the guidance and assistance of doctors. Doctors conduct one-on-one rehabilitation training for patients. Do...

Problems solved by technology

[0005] At present, most of the finger rehabilitation devices for hemiplegic patients adopt data glove exoskeleton or platform support type. Among them, the data glove exoskeleton needs the patient's hand or arm to support, and the upper limb strength of hemiplegic patients is often insufficient or even missing, which greatly reduces In addition, the driving device mostly uses active driving methods such as motors and pneumatic muscles, which can easily cause secondary damage to the patient's fingers, and the stability and safety cannot be guaranteed.

For the platform-supported rehabilitation device, its training mode is often relatively single, which cannot well meet the rehabilitation needs of patients.
