Hand function reconstruction system based on biofeedback

Abstract

The invention provides a hand function reconstruction system based on biofeedback, and belongs to the technical field of medical devices. The system comprises a glove-like myoelectricity acquisition device, a signal conversion and amplification device and a signal display device, wherein the glove-like myoelectricity acquisition device comprises gloves and a plurality of myoelectricity induction devices; the plurality of myoelectricity induction devices are arranged at the corresponding palm, hand back, wrist, multiple interphalangeal joints and multiple finger knuckles in the gloves; the signal conversion and amplification device is used for converting a myoelectric signal acquired by the glove-like myoelectricity acquisition device into an electric pulse signal and amplifying the signal;and the signal display device is used for acquiring the electric pulse signal output by the signal conversion and amplification device through Bluetooth and converting the electric pulse signal intoa real-time visual waveform to be displayed. The system is an early rehabilitation and function reconstruction system which is adopted by utilizing a human body biological positive feedback reward mechanism when the limbs are severely paralyzed and cannot be matched with function training.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a biofeedback-based hand function reconstruction system. Background technique [0002] Biofeedback is the use of precise and specialized tools to detect and amplify various information generated by the inherent physiological changes of the human body. Through the display system, this information is transformed into signals or readings that are easy for patients to understand. Under the guidance of medical staff Undergo training, so that patients can learn to use their own neuromuscular electrical activity signals to consciously launch nerve impulses through the brain, control the contraction and relaxation of muscles in various parts of the paralyzed limbs, and promote functional recovery, so as to achieve the purpose of treating diseases. [0003] Limb paralysis caused by cerebrovascular disease or craniocerebral injury is an important factor affecting the social functio...

AI Technical Summary

Problems solved by technology

Severely paralyzed limbs mainly rely on passive movement in the early stage of functional reconstruction, because patients have no intuitive experience of limb or muscle contraction, and do not know whether they can control the movement of paralyzed fingers or wrists, so they lack self-confidence, leading to inactivity in early training.
