Hand function rehabilitation device with intention perception function

Abstract

The invention discloses a hand function rehabilitation device with an intention perception function, and the device comprises a host which comprises a power module, an intention perception module, a rehabilitation training module, an evaluation analysis module, and a control module; the glove body is provided with five independent single finger sleeves matched with fingers; the transmission mechanism is used for transmitting the driving force output by the power module to the glove body so as to drive a single finger sleeve of the glove body to bend and stretch; the intention sensing module analyzes the collected pressure signals and bending angle signals of the fingers of the user and the forearm electromyographic signals of the corresponding hands, the finger movement intention of the user is judged, and therefore auxiliary driving force is provided for finger movement through the power module. The device has an intention sensing function, auxiliary driving force is automatically provided for a patient through intention sensing judgment, the patient can conduct active training, and the rehabilitation training effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to a hand function rehabilitation device with an intention perception function. Background technique [0002] According to the "2019 China Stroke Prevention Report", the total number of stroke patients in my country exceeds 13 million, and about 75% of the survivors are hemiplegia due to motor nerve damage, resulting in motor dysfunction. Nearly 80% of stroke patients will experience hand dysfunction, which is one of the most common symptoms of stroke. At present, the improvement and rehabilitation treatment of hand dysfunction at home and abroad mainly adopts the methods of repairing or reshaping damaged nerves, strengthening the strength of muscles and tendons, and completing motor learning to rebuild or improve the motor function of the affected hand. [0003] The clinical symptoms of hand dysfunction are mainly manifested as decreased muscle strength, decreased or...

Problems solved by technology

[0004] At present, many hand function rehabilitation robots have been developed and applied in the process of hand rehabilitation training at home and abroad. However, there are still many challenges to be overcome in actual use.

At present, there are the following types of problems in the products for stroke hand rehabilitation training on the market: 1), large volume, poor portability; 2), complex structure, low comfort; 3), few products with repetitive active training function, The affected hand cannot be effectively recovered; 4), the training mode is single, and the rehabilitation effect is not ideal; 5), there is no intention perception, and it is impossible to evaluate the patient's rehabilitation in real time
