The present invention provides an apparatus for evaluating sleep quality in sleep apnea patients that includes a feature extraction and an evaluator of sleep quality. The feature extraction receives EEG and ECG signals from obstructive sleep apnea patients, and extracts the times apnea occur one night, the time lasting for each apnea, and delta ratio when apnea occur during sleep in sleep apnea patients and then transport the signals to an evaluator of sleep quality. Evaluator of sleep quality evaluates the level of sleep quality in obstructive sleep apnea patients through fuzzy computing with the received signal characteristics to achieve non-invasive treatment biosignal, and to analyze if sleep quality in obstructive sleep apnea patients have improved after sleep apnea treatment in an objective way.本發明之睡眠呼吸中止症睡眠品質評估裝置,基本上係由一特徵擷取器及睡眠品質評估器所整合構成,主要由特徵擷取器接收阻塞型睡眠呼吸中止症患者之腦電圖(EEG)及心電圖(ECG)訊號,並取出阻塞型睡眠呼吸中止症患者整晚發生睡眠呼吸中止事件次數、睡眠呼吸中止事件持續時間及睡眠呼吸中止事件Delta波比例等特徵,再將此訊號特徵傳輸至睡眠品質評估器,於睡眠品質評估器接收後,透過模糊計算依據所接收之訊號特徵來判別阻塞型睡眠呼吸中止症之睡眠品質等級。俾達到以非侵入式的生理訊號,客觀性的分析阻塞型睡眠呼吸中止症患者在睡眠呼吸中止症治療前、後,對於睡眠品質上是否有效改善之目的。10‧‧‧特徵擷取器20‧‧‧睡眠品質評估器
