Portable active electroencephalogram monitor and control method thereof

The invention relates to a portable active electroencephalogram monitor and a control method thereof, belonging to the field of medical apparatus and instruments. The electroencephalogram monitor comprises an electroencephalogram signal acquisition unit, an electroencephalogram signal analysis and storage unit and an upper computer, wherein an input and output end of the electroencephalogram signal acquisition unit is connected with a first input and output end of the electroencephalogram signal analysis and storage unit, and a first digital signal input and output end of the electroencephalogram signal analysis and storage unit is connected with an input and output end of the upper computer. The portable active electroencephalogram monitor has high stability and reliability and can be used for realizing the active long-term monitoring of accidental, transient, paroxysmal or characteristic electroencephalogram activities, and the normal life, study and work of patients can not be influenced. Because long-time electroencephalogram data can be continuously recorded, the electroencephalogram monitor has important clinic value in diagnosing epilepsia and cerebrovascular diseases and studying and analyzing sleep.
