Technical Field

Background
Electrical stimulation therapy is a technique that causes a response or enhancement of the human immune system by targeted, specific, purposeful stimulation of the vagus nerve of a human through nerve current. This technique can be used to treat various diseases, such as neurological diseases, psychiatric diseases, motor system diseases, etc.
For certain diseases, such as parkinson's disease, alzheimer's disease, etc., electrical stimulation therapy may act to relieve symptoms. For example, in parkinson's disease patients, electrical stimulation therapy may alleviate symptoms such as muscle stiffness and movement disorders by stimulating the cranial nerves. For alzheimer's patients, electrical stimulation therapy can improve cognitive and memory functions by stimulating cerebral neurons.
At present, the number of the electric stimulation channels of the electric stimulation product is relatively small, the control is single, and the human-computer interface is relatively unfriendly and rigid. In addition, the prior art has the problems of crosstalk interference among the channels of the electrical stimulation and the like. The problem of crosstalk is a common problem in the design of multi-channel electrical stimulation therapy control systems. Crosstalk interference refers to crosstalk interference of signals between different channels, and causes distortion or instability of an output waveform. To address this problem, designers often employ isolation and filtering techniques, such as adding signal isolators, filters, etc., to reduce signal interference between the different channels. In addition, the coupling effect between signals can be reduced by optimizing the circuit layout and the wiring, and the anti-interference capability of the system can be improved. But the effect is not ideal at present.
In addition, the control of the electrical stimulation intensity cannot guarantee automatic closed-loop control. Aiming at some complicated functional electric stimulation treatments, the optimization and adjustment of current related parameters are more complicated, professional medical equipment and medical staff are required to operate, the effect of electric stimulation is improved through the accumulated experience of the medical staff, and the application range and popularization degree of the electric stimulation treatments are limited. At the same time, the side effects of electrical stimulation therapy are not neglected. For example, excessive electrical stimulation may cause uncomfortable symptoms such as muscle twitches, headaches, nausea, and the like.
