Abstract

The invention discloses a brain function rehabilitation assisting device based on bioelectrical feedback, comprising a brain wave monitoring module, a transcranial stimulation module and a data exchange module, wherein the brain wave monitoring module is arranged to collecting brain wave signals of a user, extract features of the signals, and monitor whether the signals are normal, the transcranial stimulation module is arranged to generate electromagnetic stimulation signals according to abnormal brain wave signals, the data exchange module is arranged to realize data exchange between the brain wave monitoring module and the transcranial stimulation module, the transcranial stimulation module comprises an electrotherapeutic/magnetotherapeutic unit, a PCM (Pulse Code Modulation) encoder, a PCM decoder and a digital-to-analog converter, the electrotherapeutic/magnetotherapeutic unit comprises at least two electrodes and at least one magnetic pole, the PCM encoder is arranged to encode waveforms outputted from each electrode to obtain a PCM-encoded waveform file, the PCM decoder is arranged to decode waveform data and true values of the respective electrodes, and the digital-to-analog converter is arranged to convert the true values into control signals, switch polarities of the electrodes, and convert the waveform data into current signals which are outputted through the electrodes. The brain function rehabilitation assisting device based on the bioelectrical feedback disclosed by the invention realizes the programmed real-time control on polarities of the electrodes for transcranial stimulation, and has a very good prospect for remote applications.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a bioelectrical feedback brain function rehabilitation auxiliary device. Background technique [0002] Transcranial direct current stimulation (tDCS) is a technology that uses constant, low-intensity direct current (0.1-2mA) to regulate the activity of neurons in the cerebral cortex. tDCS has two different electrodes and their power supply battery equipment, plus a The control software sets the output of the stimulation type, and acts on the cerebral cortex with a weakly polarized direct current. Stimulation methods include anodal stimulation, cathodal stimulation and sham stimulation. Anodal stimulation can usually increase the excitability of neurons at the stimulated site, while cathodal stimulation can reduce the excitability of neurons at the stimulated site. Unlike other non-invasive brain stimulation techniques such as transcranial electrical stimulation and transcran...
