How to use the index electroencephalograph

Abstract

The invention provides an indexing electroencephalogram device and a use method of the indexing electroencephalogram device. The indexing electroencephalogram device comprise a host and an electroencephalogram collecting device being in communication, wherein the host comprises a host communication module, a master control module and a processing module which are connected with each other; the electroencephalogram collecting device is composed of an electroencephalogram electrode and an electroencephalogram collecting unit, and the electroencephalogram collecting unit comprises an impedance detection circuit, an amplifying circuit, an analog-digital conversion circuit and an electroencephalogram communication module which are connected with each other; the electroencephalogram electrode is in communication with the impedance detection circuit, and the host communication module is in communication with the electroencephalogram communication module. Compared with the prior art, the device and the method have the beneficial effects that the number of wave forms at different frequency bands within the unit time can be rapidly counted, and the information including the amplitude and time limit of each wave form also can be conveniently extracted, thus accurate indexed information can be obtained clinically, and the accurate and discrete marking can be carried out on each wave form; the clinical workload is reduced, and the real-time monitoring and early warning on the clinical electroencephalogram digital information are realized.

Description

technical field [0001] The invention belongs to clinical monitoring medical equipment, and in particular discloses a method for using an index electroencephalograph. Background technique [0002] EEG is the brain electrical activity firstly recorded and correctly described by German Hans Berger. Since its development, the application range of EEG has also been expanded. Common EEGs include: conventional EEG, Video EEG, EEG and Evoked Potentials, Dynamic EEG, etc. At present, with the increasingly sophisticated clinical research on EEG activity, high requirements have been put forward for the digitization, diversification and real-time monitoring of EEG instruments. a trend of development. And how to extract and calculate the number and proportion of different frequency band waveforms in the EEG signal in a unit time in real time?

And how to extract and calculate the number and proportion of different frequency band waveforms in the EEG signal in a unit time in real time? The number of waveforms of different frequency bands per unit time is of great significance in clinical practice. The traditional EEG only analyzes the frequency domain distribution and proportion of waveform energy within a period of time, but cannot determine the specific number of waveforms per unit time.
