Key Features & Advantages of the 24 Channels EEG Amplifier System:

1. Professional AEEG amplifier suitable for all standard applications of routine EEG and long term EEG monitoring. Integrates all the functions of signal magnification, A/D transform, data storage, LCD display and wireless data transmission, capable of showing one channel waveform (arbitrarily and can be changed), present time, collection time, storage capacity, version information, serial number and battery status.

2. Supports up to 24 channels of monopolar EEG recording.

3. Support up to 24 hours of continuous EEG recording on DC power supply.

4. Use of DC power supply eliminates risk of electric shock to patients and prevents signal interference, and removes the need to use ground wire or other shielding features.

5. Supports real-time EEG waveform recording and display via Wireless Bluetooth transmission, or dynamic recording with flash memory card capable of storing up to 300M of EEG data (data storage capability depends fully on memory card used).

6. Fast data uploading capability: Data stored in flash memory card via dynamic recording can be quickly transmitted to desktop or laptop computer through USB2.0/USB1.1 interface.

7. Optional video system for recording, editing and displaying video images synchronously with EEG signals.

8. Optional photic stimulator for evoking patient's epilepsy seizure. Photic stimulation is synchronized with EEG waveform acquisition, and the frequency and time of photic stimulation can be set arbitrarily.

Acquisition & Settings of the 24 Channels EEG Amplifier System:

1. Colors of waveforms are in accord to colors of events, and users can mark on the waveforms with character directly; it’s available to open respiration leading sound to instruct patient's respiration frequency in a deep respiration event;

2. EEG channels can be arbitrarily set up for users to customize the layout of channels during collection process and playback analysis. This includes the choice of processing EEG waveforms with filters, baseline and other arbitrary parameters;

3. Configuration chart display and data source of physical channel configuration are displayed together at the same interface, making channel editing simpler and more intuitive;

4. Events markers enable user to mark timings of seizures or any abnormal wave occurrences during recording, whereby events marked are listed and can be traced with the event localization feature during playback;

5. Same-screen, and real-time display brain tendency chart is in synchronism with EEG waveforms acquisition. Brain tendency chart include various energy curve maps: energy curve, peak value frequency, relative energy, absolute energy, energy peak, frequency, medium frequency index, side frequency index and coma index.

Replay & Analysis of the 24 Channels EEG Amplifier System:

1. EEG mapping;

2. EEG tendency analysis;

3. EEG spectral analysis;

4. Brain waves fast playback and fast positioning function;

5. Automatic spike recognition with adjustable arbitrary spike-wave parameters;

6. User can list the events marked during replay and locate each of the event markers in the waveform. User can add, change or remove event markers based on manual observation made during recording;

7. User can also review the EEG waveforms with a different combination of parameters and filters;

8. Automatically generates EEG case reports with customizable print templates.
