Wireless "Neuropolygraph"

Purpose

A wireless electroencephalograph is a device required to perform the monitoring of the bio-electric potentials of the human brain with the simultaneous registration of three polygraph channels: EMG, ECG, and EOG. The data is recorded simultaneously and in the real time to a personal computer or to SD card. The device can be fixed on the head of the patient. Such solution makes it possible to provide the highest quality of EEG as in stationary conditions, as well as when the patients move around without being linked to a computer, a room or even a medical institution.

The uniform electrode model allows using the device on heads of various sizes with the same level of comfort. Furthermore, the device can be used for children and babies. 

This device can also be used for routine examinations. In order to do that it can be added with a wireless photostimulation device. As a result, this device is a versatile system for high-quality EEG monitoring and registration.

The device offers the following features before starting EEG recording:

• record information about the patient to the database
• selection of the monopolar location and working channels (if required)
• adjusting filter settings
• selection or creation of the registration protocol
• checking the quality of electrodes positioning.

The device supports the following features during the real-time usage:

• changing scales of time, amplitude, and filter parameters
• custom range filters allowing selecting specific frequency ranges
• checking the quality of electrodes positioning (impedance measuring)
• filtering power line disturbances
• choosing bipolar schemes
• recording with/without the protocol, custom order of samples
• notepad with timestamps and events
• video monitoring using several cameras

The device supports the following features during the real-time usage and after the registration:

• spectral analysis
• the cartographical analysis in 2D and 3D
• correlation analysis
• automatic artifact detection

The device supports the following features after the registration of EEG:

• restoring lost fragments of EEG from SD card
• automatic searching of ranges with pathologic activity
• automatic report generation in text or in table formats
• recording results and video to CD
• import/export of examination results
• EEG signals export in EDF and CSV
• remote impression writing using the cloud storage or a network folder

Software features

1. The convenient database allows fast patient information adding.
2. Supports parallel recording from two or more cameras.
3. EEG registration can be carried out with available of with custom protocols.
4. Quality of the electrode attachment control by measuring the impedance between the electrodes in real-time.
5. Both reports and examination information can be stored and transferred using the cloud storage.
6. Automated impression creation for functional batches in the report.
7. Ability to use digital filters as in real time, as well as after the signal registration.
8. Results of the examination can be exported in CSV, EDF, and EDF+formats, and processed using the most popular international software: LORETA, EEGLAB, BESA, CURRY etc. 
9. Supports restoration of the EEG data from a flash card in case if the patient went out of the receiver coverage.

Main types of EEG processing:

• automatic mode for artifacts identification
• automatic searching of ranges with pathological activity, including continuous records
• spectral and correlation analysis
• the cartographical analysis in 2D and 3D
• calculation of the hemispheric asymmetry, index, and the rhythm frequency
