Wireless Polysomnography System

Description

Key Features

  • Upgraded wearing experience, non-invasive and high fit: High-elastic flexible electrodes are adopted to realize non-invasive fit to human skin, which fundamentally improves the discomfort of wearing traditional rigid electrodes and enhances patients' compliance with monitoring.
  • Full coverage of gold-standard signals, no blind spot in monitoring: It can completely monitor all categories of sleep gold-standard signals such as electroencephalogram, electrooculogram, submental electromyogram, oronasal airflow, electrocardiogram and blood oxygen. The data dimension is consistent with hospital professional-level monitoring, providing a comprehensive basis for diagnosis.
  • Wireless transmission breaks scenario limitations, applicable to hospital and home monitoring: Equipped with multi-standard wireless transmission technology of 5G/Bluetooth dual mode + wireless WIFI, it completely gets rid of cable constraints, and realizes the extension of accurate monitoring from hospital specialist departments to home scenarios, adapting to diversified monitoring needs.
  • AI + manual dual analysis, combining accuracy and efficiency: It is equipped with a sleep deep learning model, which achieves a sleep staging accuracy rate of >90% through multi-modal signal fusion analysis, and can automatically complete multi-dimensional analysis such as sleep trend, respiratory disorder and oxygen desaturation data; combined with manual interpretation function, it double guarantees the accuracy of diagnosis results and reduces the risk of missed and misdiagnosis.

Advantage
  • Flexible sensing technology solves the problems of wearing experience and data distortion

Market Challenge:Traditional PSG’s rigid electrodes and cables cause discomfort, disrupt sleep, and lead to inaccurate data

NCC Solution;Flexible non-invasive electrodes + wireless transmission improve wearing comfort, avoid sleep disruption, and ensure data authenticity

  • Wireless multimodal collaboration technology breaks scenario limitations

Market Challenge:Wired monitoring is limited to hospitals, failing to meet home needs, with hospital beds in short supply and long appointment cycles

NCC Solution;5G/Bluetooth/WIFI multi-mode wireless transmission enables hospital-home dual-scenario monitoring, easing hospital resource pressure

  • AI Large Model + manual dual analysis improves data processing efficiency and accuracy

Market Challenge:Fully manual analysis of multi-dimensional data is inefficient, and primary institutions lack professional physicians

NCC Solution;AI automatic analysis (sleep staging accuracy >90%) + manual review improve efficiency and reduce reliance on primary physicians

  • HD infrared real-time monitoring realizes dual-dimensional diagnosis of "physiological parameters + behavior

Market Challenge:No night visual monitoring, making it hard to accurately classify sleep disorders with only physiological parameters

NCC Solution;Optional 1080P HD infrared monitoring captures behavioral data even at night (lights off), supplementing diagnostic basis

  • Disposable specialized electrodes adapt to the needs of rapid primary screening

Market Challenge:Traditional electrodes are cumbersome to apply and unstable in signal, lowering primary screening efficiency

NCC Solution;Dedicated disposable electrodes simplify application, ensure stable signals, and adapt to primary rapid screening
