Household high-precision transcranial current stimulation system with remote monitoring function

Abstract

The invention discloses a household high-precision transcranial current stimulation system with a remote monitoring function. The system comprises a main circuit (1), a micro-control unit (2), a display screen (3), a communication module (7), a mobile terminal application program (8), an AD conversion module (6), an electrode array (9), a decoding circuit (10) and an isolation drive circuit (11),wherein the main circuit (1) comprises an adaptive power supply (12), a boost-buck chopper circuit (13), a frequency modulation and waveform generation circuit (14) and an IGBT selection array (15) which are connected with one another; each electrode of the electrode array needs to be controlled by two IGBTs, the two IGBTs control one electrode, cathode control and anode control over the electrodes are achieved respectively, control signals of the two IGBTs controlling the same electrode must be interlocked, and high-precision stimulation and multi-focus stimulation on specific parts of a brain are achieved through on-off control over the cathode and the anode of each electrode. The use of the transcranial current stimulation system by a user at home is satisfied.

Description

technical field [0001] The invention relates to the fields of biomedicine and neural engineering, and has broad application prospects in the treatment and rehabilitation of neuropsychiatric diseases and the exploration of brain functions. Background technique [0002] Neuropsychiatric disorders have been recognized worldwide as a major public health problem with significant morbidity and mortality. According to the report of the World Health Organization, the incidence of mental illness is close to or even exceeds 35% in many countries. Especially in recent years, due to the rhythm of life and work pressure, depression has become second only to major diseases such as AIDS and heart disease. Ranked fifth worldwide disease. According to data from the Mental Health Center of the Chinese Center for Disease Control and Prevention (2017), the number of patients with various types of mental illness in China has exceeded 100 million, ranking first in the world. The economic, famil...

Problems solved by technology

[0004] At present, there are some tDCS, tACS and tRNS devices on the market, but most of them can only achieve a single mode of current stimulation, and often lack a friendly interface

And one of the major hurdles in transcranial electrical stimulation research is the need for patients to go to the hospital for repeated treatments lasting weeks or even months, which poses a great burden to most patients with neuropsychiatric diseases and their families
