A multi-channel transcranial electrical stimulation device and method thereof

Abstract

The invention discloses a multi-channel transcranial electrical stimulation device and a method thereof, comprising a host computer module, an ARM control module, an FPGA waveform generation module and an analog circuit module; the ARM control module is mainly responsible for control data sent with the host computer module, and The control data is transmitted to the RAM storage unit of the FPGA waveform generation module through the variable static storage controller; the FPGA waveform generation module includes multiple independent channels, each channel has a waveform generation module, and each channel can independently generate waveforms , and the control data obtained by the RAM storage unit can control the generation of the waveform of each channel; can realize the adjustment of each single channel parameter under multi-channel transcranial electrical stimulation, increase the current feedback, and make the stimulation current stable.

Description

technical field [0001] The invention belongs to the technical field of medical machinery; in particular, it relates to a multi-channel transcranial electrical stimulation device and a method thereof. Background technique [0002] Transcranial Electrical Stimulation (TES) is a non-invasive neurostimulation technology that applies a specific, low-intensity current (-2 to +2 mA, above 2 mA is only used for scientific research) to specific brain regions through electrodes. , to achieve the purpose of regulating the neural activity of the cerebral cortex. This technology includes a variety of stimulation methods, which can be divided into: Transcranial Direct Current Stimulation (tDCS), Transcranial Alternating Current Stimulation (tACS), Transcranial Random Noise Stimulation ( Transcranial Random Noise Stimulation, tRNS). Initially the technology was used to help patients with brain injuries such as strokes. Studies have shown that in healthy adults, transcranial electrical s...

Problems solved by technology

[0004] At present, there are many transcranial electrical stimulators on the market, which can effectively stimulate patients, but they still have the following shortcomings: the treatment mode and function are relatively single and specific, and there is a high cost; multi-channel transcranial electrical stimulation The stimulation equipment cannot realize the independent parameter adjustment of each single channel, so that more diverse stimulation methods cannot be realized; there is no current feedback, and the output current cannot be monitored in real time, so the safety cannot be guaranteed; it cannot be expanded to more channels, It is impossible to stimulate more effective stimulation points on the head; it lacks a friendly and easy-to-operate interface, and cannot change parameters in real time and quickly, causing inconvenience to users
