Description

technical field [0001] The invention belongs to the technical field of transcranial direct current stimulation, and in particular relates to a transcranial direct current stimulation device and a data processing method. Background technique [0002] Cranial electrotherapy stimulation (CES for short) is a treatment method completely different from traditional drug therapy and electric convulsion therapy. A series of neurotransmitters and hormones that are closely related to anxiety, depression, insomnia and other diseases, in order to achieve the treatment of these diseases. However, the existing transcranial direct current stimulation devices need to rely on professionals to set new electrical stimulation parameters according to the changed state to realize the adjustment of electrical stimulation parameters, which makes the adjustment of electrical stimulation parameters more complex and poor in real-time; at the same time, brain-computer interfaces often The data of multi...

Problems solved by technology

However, the existing transcranial direct current stimulation devices need to rely on professionals to set new electrical stimulation parameters according to the changed state to realize the adjustment of electrical stimulation parameters, which makes the adjustment of electrical stimulation parameters more complex and poor in real-time; at the same time, brain-computer interfaces often Need to collect data of multiple leads, because too many leads increase a lot of redundant information, and also increase the complexity of calculation

[0003] To sum up, the problem existing in the existing technology is: the existing transcranial direct current stimulation device needs to rely on professionals to set new electrical stimulation parameters according to the changed state, realize the adjustment of electrical stimulation parameters, and make the adjustment of electrical stimulation parameters more complicated. High, poor real-time performance; at the same time, the brain-computer interface often needs to collect data from multiple leads, because too many leads increase a lot of redundant information, and also increase the complexity of calculations

[0004] At the same time, the existing stimulation device has no safety protection measures, and all parameters are manually set, which is highly subjective
