In clinical practice work, the inventor finds that some epileptics are expert in long-range VEEG observation process, and in the time of tens of seconds, obvious abnormal change has just appearred in frequency, the rhythm and pace of moving things and the waveform of epileptic's scalp EEG before epilepsy.Particularly for certain epileptic, before its epilepsy, the change of abnormal electroencephalogram has obvious mechanical property, and the epilepsy clinical episodes begins to begin paradoxical discharge with EEG and exists obvious time delay.

Summary of the invention

Can't predict in order to solve clinically epilepsy the problem of refusing the long-term taking antiepileptic with some epileptics, the invention provides a kind of portable early warning appearence of epilepsy's breakout that can carry out constantly eeg monitoring, the electricity variation of identification brain and the early warning at the focal position of brain, to overcome the main deficiency of prior art.

For realizing above purpose, implementation procedure of the present invention is as follows:

A kind of early warning appearence of epilepsy's breakout comprises eeg signal acquisition unit, Figure recognition unit and alarm unit,

The eeg signal acquisition unit carries out focal EEG signals monitoring in real time, and 2～4 antimagnetic brain electrical monitoring electrodes of eeg signal acquisition unit employing gather EEG signals;

The Figure recognition unit storage epileptic forebrain electrical anomaly discharge figure that shows effect, the brain wave that the identification epileptic presets;

Alarm unit is connected according to monitor data with the Figure recognition unit and sends alarm signal.

Epilepsy method for early warning of the present invention comprises the following steps:

(1) fix by long-range video eeg monitoring screening discharge position and discharge and clinical episodes have the epileptic of dependency;

(2) the front brain electrical anomaly discharge figure of this epileptic's clinical episodes is stored in startup Figure recognition unit, as default figure;

(3) select 2-4 antimagnetic brain electrical monitoring electrode, Real-Time Monitoring is carried out at the corresponding scalp position that is placed in epileptic's discharge;

(4) monitor default figure when the Figure recognition unit, start immediately alarm unit.

Can't predict in order to solve clinically epilepsy the problem of refusing the long-term taking antiepileptic with some epileptics, the present invention adopts long-range video eeg monitoring technology to the epileptic, find and grasp the rule that this patient's epilepsy forebrain electricity changes, research and develop a kind of portable early warning appearence of epilepsy's breakout that can carry out constantly eeg monitoring, the electricity variation of identification brain and the early warning at the focal position of brain.With 2-4 electrode arrangement in corresponding brain district; after brain electricity before monitoring epilepsy changes; start immediately this system early warning device; in time remind patient's epilepsy to show effect; in order in time carry out self-protection; intervene and stop its epilepsy, removing patient and family members to the worry of epilepsy, improving patients ' life quality.
