Abstract

The invention provides a difference-frequency electric stimulation device, system and method. The device comprises an input module, a central processor, a signal generation module and a signal outputmodule connected sequentially; the signal output module comprises multiple output interfaces, and each output interface is connected with one pair of electrodes; and at least two pairs of electrodes are arranged in a stimulated position of a stimulated object. Via the two or more pairs of electrodes, the electric stimulation device transmits two or more currents of different frequencies to the stimulated object, a low-frequency modulated pulse current (namely a difference frequency signal) is generated in a crossed area of the currents, and the low-frequency modulated current has an adjustmenteffect for brain cells. The low-frequency modulated current can stimulate the deep of the brain without influence on superficial neuron cells, and thus, the defect that the low-frequency current cannot reach deep in the brain is overcome, the risk of operation is reduced via an non-intrusion feature, the safety is high, a user is more willing to accept the device, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a difference-frequency electrical stimulation device, system and method. Background technique [0002] Due to the fast pace of modern life and high work pressure, many people are troubled by some brain diseases. In addition, the elderly are facing the problem of gradual decline in cognitive function. Therefore, people hope to improve the treatment of some brain diseases through some feasible technologies. cognitive ability, improve their brain function. [0003] At present, electrical stimulation of the brain is usually performed to treat brain diseases and improve brain function. Because brain cells with low-pass characteristics can only respond to currents with a low frequency (frequency range: about 1-200Hz), and low-frequency currents cannot directly penetrate into the brain tissue without affecting other brain regions, traditional deep brain stimulation (DBS) , dee...
