Multi-parameter adjustable transcranial current stimulation system

Abstract

The invention provides a multi-parameter adjustable transcranial current stimulation system. The system comprises seven mutually connected parts: namely a main circuit, a conductive electrode, a micro-control unit, an AD module, a WIFI module, a display screen, and a mobile terminal application program. The main circuit comprises a power supply part, a voltage-regulating circuit and a frequency-modulating circuit, wherein the power supply part, the voltage-regulating circuit and the frequency-modulating circuit are connected with one another. According to the technical scheme of the invention, the stimulation system can realize the selection among three current stimulation modes, namely the tDCS mode, the tACS mode and the tRNS mode. In the tDCS current stimulation mode, the current amplitude can be adjusted within the range of 1mA-10mA. In the tACS current stimulation mode, the current amplitude can be adjusted within the range of 1mA-10Ma and the current frequency can be adjusted within the range of 1KHz-2KHz. In the tRNS current stimulation mode, the selection among different noise types, including low frequency, medium frequency, high frequency, white noise and the like, is realized. Meanwhile, users can monitor stimulation parameters and search the stimulation history according to needs by a mobile terminal.

Description

Technical field [0001] The invention relates to the field of biomedicine, in particular to a multi-parameter adjustable transcranial electrical stimulation system. Background technique [0002] Neuropsychiatric diseases have become a major killer that endangers human health and life. The state of neuropsychiatric diseases in my country is worrying. Statistics in 2012 show that the number of patients with various mental diseases in China has exceeded 100 million, ranking first in the world. The economic, family, social and medical burdens brought about by it have become the largest burden of all diseases. At present, three methods of medicine, surgery and psychological counseling are mainly used for the treatment of neuropsychiatric diseases. These methods have their own shortcomings: drug treatment can not cure the disease and will have large side effects; surgical methods have high risks and cause irreversible damage to the human body , And accompanied by sequelae; psychologic...

AI Technical Summary

Problems solved by technology

At present, three methods are mainly used for the treatment of neuropsychiatric diseases: drugs, surgery, and psychological counseling. These methods have their own shortcomings: drug therapy cannot cure the disease and has relatively large side effects; surgical methods are risky and cause irreversible damage to the human body , and accompanied by sequelae; psychological counseling is mainly for mild diseases or as adjuvant therapy in other ways

[0004] There are currently some tDCS, tACS and tRNS devices on the market, but most of them can only complete one mode of current stimulation, and often lack a friendly interface, which makes it inconvenient for patients to use
