Description
また、本発明は、前記圧力計測用マットの内径の小さな前記接続管路は、内径の大きな前記接続管路に比べて長い管路長を有していることを特徴とする。
また、本発明は、前記圧力計測用マットの内径の小さな前記接続管路が、内径の大きな前記接続管路に比べて開口比の小さな絞り部、又は、多くの絞り部を有していることを特徴とする。
また、本発明は、前記圧力計測用マットの入力された圧力が内径の小さな前記接続管路で前記圧力検知箇所に導かれる前記媒体収容体は、入力された圧力が内径の大きな前記接続管路で前記圧力検知箇所に導かれる前記媒体収容体に比べて、肉厚に形成されていることを特徴とする。
また、本発明は、前記圧力計測用マットの各前記媒体収容体は管路から構成されており、入力された圧力が内径の小さな前記接続管路で前記圧力検知箇所に導かれる前記媒体収容体は、入力された圧力が内径の大きな前記接続管路で前記圧力検知箇所に導かれる前記媒体収容体に比べて、小さな内径を有していることを特徴とする。
図1は、本発明を適用した睡眠測定装置1の構成の概略を示す外観図である。この睡眠測定装置1は、圧力計測用マット2上に横になった被験者の脈拍、呼吸、体動等の生体現象に由来して発生する振動を検出して睡眠中の生体データを生成し、この生体データに基づき睡眠に関する様々な指標を算出する装置である。睡眠測定装置1は、圧力計測用マット2と、チューブ25により圧力計測用マット2と繋がれた制御ボックス4と、ケーブル線6により制御ボックス4と電気的に接続された外部端末装置5とを備えて構成されている。本実施形態では、圧力計測用マット2の上に寝具7を敷き、この寝具7の上に横になった被験者の生体データを睡眠測定装置1により収集する場合について説明する。
