PROBLEM TO BE SOLVED: To provide a biological function examination device, a biological function examination method and a program for examining biological functions with high reproducibility and accuracy based on biological information during sleep.SOLUTION: A biological function examination device 1 comprises: a detection unit 3 for detecting a biological information signal of a living body 2; a signal separation unit 9 for separating the biological information signal detected by the detection unit 3 into a pulse wave signal, a respiratory signal, and a body motion signal; a sleep state/stage determination unit 10 for determining whether a sleep state and a sleep stage of the living body 2 correspond to either a REM sleep state, a deep sleep state, a shallow sleep state, or an awakened state on the basis of the pulse wave signal and the body motion signal; a circulatory organ function evaluation unit 11 for extracting the pulse wave signal of the living body 2 in a deep sleep state and evaluating a circulatory organ function of the living body 2; and a brain control function evaluation unit 12 for extracting the body motion signal of the living body 2 in a REM sleep state and evaluating a brain control function of the living body 2.SELECTED DRAWING: Figure 1 【課題】睡眠中の生体情報に基づいて生体機能を高い再現性かつ精度よく検査するための生体機能検査装置、生体機能検査方法及びプログラムを提供する。【解決手段】生体機能検査装置１は、生体２の生体情報信号を検出する検出部３と、検出部３によって検出された生体情報信号を脈波信号、呼吸信号及び体動信号に分離する信号分離部９と、脈波信号及び体動信号に基づいて、生体２の睡眠状態及び睡眠段階がレム睡眠状態、深い睡眠状態、浅い睡眠状態及び覚醒状態のいずれに該当するかを判定する睡眠状態・段階判定部１０と、深い睡眠状態にある生体２の脈波信号を抽出して、生体２の循環器機能を評価する循環器機能評価部１１と、レム睡眠状態にある生体２の体動信号を抽出して、生体２の脳制御機能を評価する脳制御機能評価部１２とを有する。【選択図】 図１
