Wireless 24-channel electroencephalograph "NeuTec"
Wireless 24-channel electroencephalograph is required for monitoring of cerebrum biopotentials, and
registration of three polygraphic channels: EMG, ECG and EOG. A record can be taken both in real time with signal reflection on the screen and with record on SD card with ability of further editing. The device is set on patient's head, that allows to obtain a high-quality record of physiological cerebrum, muscles and heart biosignals both in stationary conditions and in real-life conditions, and also while moving.
General electrode system consists of two detachable cables with electrodes, applied for the caps of different
size, that allows to use the device without significant difficulties both for the patients with different skull's size and for infant children.
Device's fastening to the cap allows to avoid artifacts, appearing under head movements. Base configuration contains three helmets with electrodes of different sizes. The system can be also completed by the helmets of own production.
Device is set for EEG prolong monitoring undertaking (it operates up to 10 hours without recharging) both in
real-time with data reflection and saving on hard disk, and an ability of off-line working with signals record on SD card, what is settled into device. After undertaking an examination with the help of a standard card reader data from card are copied on the computer by means of software.
Analysis of prolong records is taken foremost with aim of quick exposure of pathological areas. There is a
special mode to do it, that allows software to define all the areas of pathological activity with the ability of further editing. Also spectral and correlation analysis, two- and three-dimensional topographic mapping are realized.
A record and results are saved in database, that allows to replay and to look over them, and also to record
on external medias (DVD, flash drives, external hard disk).
Registration of patient's video image by two rowing camera is implemented in this system combining with
EEG record registration.
Functions and capabilities
Pediatric and general neurology;
Monitoring and training in professional activities;
Work with the electroencephalogram is divided into the modes of registration and EEG analysis. In the
registration mode in real time according to the scheme of the electrodes placement, under the selected examination protocol or without a protocol signal is input into the personal computer and displayed on the screen. In parallel it is possible to log events, monitor the patient’s video image, change the electroencephalograph parameters (sensitivity, sweep, filters).
In the analysis mode advanced estimation of the electroencephalography, spectral analysis, correlation
analysis, topographic mapping, search of pathologic activity regions is available. The program has flexible and easy-to-use interface, enables to adjust registration and analysis modes for needs of a concrete user.
