Electrical stimulation device integrating transcranial electrical stimulation and vagus nerve stimulation

Abstract

The invention discloses an electrical stimulation device integrating transcranial electrical stimulation and vagus nerve stimulation. The electrical stimulation device is composed of a transcranial electrical stimulation module and a vagus nerve electrical stimulation module. The transcranial electrical stimulation module is composed of an ARM control unit, an FPGA waveform generation unit and ananalog circuit. The ARM control unit sends control command waveform parameter information to the FPGA through the FSMC; the FPGA waveform generation unit generates a four-channel digital waveform signal. Firstly, the four-channel digital waveform signal is converted into a four-channel analog signal waveform through a digital-to-analog conversion circuit, then the four-channel analog signal waveform is amplified through a primary amplification circuit, interference signals except waveform signals are filtered out through a filter circuit, and then the waveform is amplified to the waveform amplitude required by the control unit through a secondary amplification circuit to be output. The electrical stimulation device is quite high in safety, the current value, waveform parameters and the like need to be adjusted in real time, the human body safety is guaranteed to be not damaged, and meanwhile, the module can output constant-current stimulation and can output different kinds of waveformsin a transcranial alternating-current stimulation mode.
