CE CONTEC KT88-1016 EEG 16 Channel Digital EEG and Mapping System for Clinical Brain Diagnosis

The KT88 Digital Brain Electric Activity Mapping system from CONTEC is a comprehensive tool for capturing and analysing brain electrical activity. It collects EEG signals through electrodes applied to the scalp, then uses integrated amplification, A/D transformation, and PC-based auto-analysis to generate an electroencephalogram displayed with colour depth. The system is specifically applicable for diagnosing conditions such as epilepsy, intracranial inflammation, cerebrovascular diseases, and brain tumours, making it a valuable asset for neurology departments and clinics. With its 16-channel capacity and optional ECG channels, it provides detailed waveform data for clinical assessment. The device operates via a standard USB interface, ensuring easy connection to a computer for both power and data transmission.

Features and Construction

The KT88-1016 is built around a bioelectricity amplifier for distilling brainwaves, with a continuous recording time of up to 24 hours. It includes a full-automatic calibration system and a digital filter with selectable window types. The system adheres to the international 10/20 electrode placement standard, and leads can be changed during replay for flexibility.

Recording and Amplification

The device offers 16 EEG channels with a sampling rate of 100 dots/s and a magnification multiple of 10,000. Noise level is kept at 5µVp-p or less, and common mode rejection ratio (CMRR) is at least 90dB. Input impedance is 10MΩ or greater, ensuring reliable signal capture even in challenging conditions. Patient leak current is below 10µA for safety.

Display and Playback

Display speed (paper speed) can be set from 5 to 120 mm/s, with amplitude adjustable from 1 to 50 mm/50µV. Playback speed ranges from 1x to 60x, allowing detailed review. A special subdividing time line divides one second of waveform into five parts for easier visual inspection by clinicians.

Digital Filter and Analysis

The digital filter system can be configured as required, offering different window types. Automatic analysis includes power spectrum analysis and pathologic wave detection. The system can display multiple graphs simultaneously, including various BEAM types, numerical BEAM, compressed spectrum graphs, and trend graphs.

Uses and Placement

The KT88-1016 is intended for hospital neurology departments, clinics, and diagnostic centres where EEG recording and brain mapping are performed. Its compact dimensions (186 x 135 x 89.2 mm) and light weight (550g) make it suitable for desktop use in a clinical setting. The optional video function with a USB camera allows simultaneous video recording for seizure monitoring.

Epilepsy and Seizure Diagnosis

The system is particularly suited for long-term monitoring of epilepsy patients, with continuous recording up to 24 hours. The flash stimulator can be used for photic stimulation during routine EEGs. Event markers for opening eyes, closing eyes, and flashing, along with user-defined events, help correlate clinical events with EEG changes.

Cerebrovascular and Inflammatory Conditions

For evaluating intracranial inflammation or cerebrovascular disease, the system provides detailed frequency analysis and waveform examination. The electronic frequency ruler and partial enlarging window enable accurate measurement of EEG period, amplitude, and frequency, aiding in diagnosis.

Research and Data Exchange

Case management functions include case export and import, with storage on MO or CD-RW disks. Files can be transformed into EDF and BDF data format for academic exchange and further analysis. The integrated image and character report can be edited and switched to Word documents for easy reporting.

Benefits and Buying Value

The KT88-1016 offers a professional-grade EEG solution with a focus on data security and analysis flexibility. Its isolation transformer and dual power supply isolation ensure patient safety. The USB interface simplifies setup and integration with existing PC infrastructure.

Safety and Compliance

The device meets safety standards as a Class II type BF applied part, with 50Hz interference suppression of at least 30dB. It holds SFDA and CMC certificates, confirming its suitability for clinical use in China. Operational temperature range is +5°C to +40°C with relative humidity up to 85%.

Optional Upgrades

Optional additions include SpO2 monitoring and a video function with a USB camera for recording patient activity during EEG. The system can be expanded with additional ECG channels if required. The flash stimulator can be controlled manually or automatically during sampling.

Why Choose This Product

For clinics and hospitals needing reliable digital EEG with long-term recording capability and advanced analysis features, the KT88-1016 provides a cost-effective solution. Its compact size, USB connectivity, and comprehensive software support make it a practical choice for neurology departments seeking to upgrade from older analog systems.
