Polysomnograph with SpO2 monitoring

with EMG monitoringwith NAF monitoringwith EOG monitoring

Key Features

• Upgraded wearing experience — non‑invasive, high conformity: High‑elastic flexible electrodes provide non‑invasive contact with the skin, reducing discomfort associated with rigid electrodes and improving patient compliance for prolonged monitoring.
• Full coverage of sleep gold‑standard signals: Continuous acquisition of EEG, EOG, submental EMG, oronasal airflow, ECG and SpO₂, delivering data dimensions consistent with hospital‑grade monitoring to support comprehensive diagnosis.
• Wireless transmission for hospital and home use: Multi‑standard wireless connectivity (5G/Bluetooth dual‑mode + Wi‑Fi) eliminates cable constraints and enables accurate monitoring across clinical and home scenarios.
• AI + manual dual analysis for accuracy and efficiency: Integrated sleep deep‑learning model achieves sleep staging accuracy >90% by multi‑modal signal fusion; automatic analyses include sleep trends, respiratory events and oxygen desaturation, with manual review capabilities to ensure diagnostic reliability.
