Whole brain region electroencephalogram cap for transcranial magnetic stimulator treatment

Abstract

The invention relates to the technical field of multichannel electroencephalogram acquisition, in particular to a whole brain region electroencephalogram cap for transcranial magnetic stimulator treatment, which comprises a cap body and 59 conventional electrode point positions arranged on the cap body and used for covering the whole brain region of the brain, the cap body further covers the cerebellum position of a human body, the cap body is provided with PO9, O9, IZ, O10, PO10, CB1, CBz and CB2 electrode point positions at the cerebellum position of the human body, and the cap body is provided with a plurality of electrode points. The electroencephalogram cap comprises 59 conventional electrode point positions and PO9, O9, IZ, O10, PO10, CB1, CBz and CB2 electrode point positions, C-shaped electrodes are installed on the 59 conventional electrode point positions and the PO9, O9, IZ, O10, PO10, CB1, CBz and CB2 electrode point positions, the other ends of the two extension lines are connected with two patch electrodes respectively, and the C-shaped electrodes are made of silver materials and coated with silver chloride. Meanwhile, when a patient uses the transcranial magnetic therapeutic apparatus for treatment, the phenomena of electrode eddy current and electrode heating caused by the therapeutic apparatus are reduced; the stimulation of the electrode of the electroencephalogram cap on the scalp of a patient and the influence on electroencephalogram signals are relieved.

Description

technical field [0001] The invention relates to the technical field of multi-channel EEG acquisition, in particular to a whole-brain-region EEG cap used for treatment with a transcranial magnetic stimulator. Background technique [0002] The human brain EEG signal has a voltage of tens of microvolts. EEG acquisition is to collect this microvolt-level voltage through EEG electrodes, and record its waveform by the acquisition terminal, and then analyze and process the brain EEG waveform. , It can realize the identification of consciousness state, automatic detection of epilepsy, sleep monitoring and diagnosis and treatment of various brain diseases. [0003] The multi-channel EEG acquisition method usually adopts a stretchable EEG cap made of elastic material, and the electrodes have been installed on the fixed position of the EEG cap. However, the collection and analysis of cerebellum electrical signals play an important guiding role in the judgment of human brain neurologic...

Problems solved by technology

[0003]The multi-channel EEG acquisition method usually adopts a stretchable EEG cap made of elastic material, and the electrodes have been installed on the fixed position of the EEG cap. The search found that the existing EEG caps are all based on the national standard 10-20 electrode positions and their extended electrode position distribution, and cannot collect EEG signals in the human cerebellum area, and the collection and analysis of cerebellum electrical signals is essential for the judgment of human brain neurological diseases. It has an important guiding role; on the other hand, due to its good therapeutic effect on neurological diseases such as depression and cognitive dysfunction or ne...
