Abstract

The invention belongs to the technical field of nervous system disease electrical stimulation, relates to a biological tissue time domain interference electrical stimulation device and a using methodthereof. The time domain interference electrical stimulation device comprises an AC signal source, a signal filtering module, a voltage control conversion module, a linear power source and a power source filtering module; two pairs of stimulation electrodes are attached to a body surface of a tissue to be stimulated, and two sinusoidal alternating electric fields at the frequency f and the frequency f+Delta f are applied to the two pairs of electrodes respectively, and when the two electric fields with similar frequencies meet, an interference phenomenon in the time domain can occur, and an envelope electric field is formed; and the frequency of the envelope electric field is the frequency difference between the two sinusoidal alternating electric fields. The electrical stimulation changepeak of the envelope electric field can be intensely focused in a specific region of the tissue in a spatial dimension through the time domain interference technique, so the purpose of non-invasive and precise regulation of electrical stimulation of a tissue targeted region only by adjusting the positions of the surface mount electrodes and the stimulation current ratio of the two pairs of electrodes.

Description

technical field [0001] The invention belongs to the technical field of nerve electrical stimulation, and relates to a biological tissue time-domain interference electrical stimulation device and an application method thereof. Background technique [0002] At present, the clinical use of electrical stimulation or magnetic stimulation has been proven to have potential therapeutic effects in the treatment of neurological diseases, but these technologies also have many important limitations in clinical application. Nerve electrical stimulation has been widely used in pain, Parkinson's disease, traumatic brain injury coma awakening, epilepsy and post-hypoxic vegetative state, etc. Deep brain stimulation (DBS) uses stereotactic technology to directly apply electrical stimulation to disease-related brain regions by embedding stimulating electrodes in the deep part of the brain. Stimulator control and adjustment outside the brain. DBS has the advantages of clear target and high se...
