Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 When in use, the EEG cap 2 needs to be worn on the head of the user 1, the electrode cap 2 is connected to the preamplifier 3, the preamplifier 3 is connected to the host 4, and the host computer 5 is connected to the host via WiFi. When the present invention works, it can collect multi-channel scalp EEG signals of user 1, and perform real-time closed-loop adjustment on the output waveform of transcranial electrical stimulation according to the pre-set multi-channel EEG signal real-time analysis algorithm and closed-loop control strategy, and simultaneously collect The received original EEG signal will be sent to the host computer 5 via WiFi and can be displayed and recorded on the host computer 5 .

[0023] see figure 2 , The electrode cap 2 is composed of an elastic cap 21, a plurality of disk-mounted electrodes 22 fixed on the elasti...

Abstract

The invention belongs to the technical field of medical equipment, in particular to a non-invasive closed-loop transcranial electrostimulation device. The device of the invention comprises an electrode cap, a preamplifier, a host computer and an upper computer. The electrode cap is worn on the user's head and comprises a plurality of disc electrodes for collecting EEG signals and applying electrical stimulation. The preamplifier is connected with the electrode cap through a cable and comprises a plurality of selector switches and a plurality of amplifiers, which are used for switching the function of collecting and stimulating each electrode and preamplifying the EEG signal. The host computer is connected with the preamplifier through the cable, which is used for the acquisition, real-timeoperation, transmission of EEG signals and the generation of transcranial electrical stimulation signals. The host computer is wirelessly connected with the host computer, and is used for receiving the multi-channel EEG signals recorded by the host computer and displaying and recording the signals; or the signal real-time analysis algorithm and closed-loop control strategy are downloaded to the host. The invention can be used in the field of scientific experiment and rehabilitation treatment, and can utilize multi-channel EEG signal as feedback to carry out closed-loop electrical stimulation.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a non-invasive closed-loop transcranial electrical stimulation device. Background technique [0002] Due to the existence of the blood-brain barrier in the human body, many drug molecules cannot act on the brain through the blood circulation system, and the available drugs for neurological diseases such as Parkinson's disease, depression, and autism are very limited. Coupled with the reduced curative effect and drug side effects caused by human body drug resistance after long-term medication, most patients cannot be cured by drugs. [0003] In order to improve the therapeutic effect and reduce the side effects of drugs, people use electrical, optical, magnetic and other physical stimuli to regulate the nervous system. In particular, deep brain stimulation has achieved good results in the treatment of Parkinson's disease. However, deep brain stimulation requ...
