Mobile Digital Eeg Equipments

Following are the Main Features of Mobile Digital EEG Equipments :-
* Adopting Large Scale Integrated circuit (LSI) and improved anti-jam capability.
* Doubly isolated the power supply and brain electrical signal to prevent creepage and to insure security.
* Record 16 leads EEG without pencils.
* Two ECG leads and one breathing lead for option.
* Function of various event description such as open or close eyes, deep breathing and flash stimulation.
* Arbitrarily set lead modes such as monopole, dual-pole and reference electrode.
* Choose any lead to enlarge and automatically measure EEG waveform.
* Auto-replay EEG wave and real-time compressed chart-array map.
* Arbitrarily choose histogram, graph, and graph and percentage map.
* Continuously replay spike wave relief map and dynamic 3D rotated relief map.
* Arbitrarily set digital filtering, formfeed speed, gain, transmission bands and time constant settings.
* Self-contained medical record management system and manifold report pattern.
