Claims (2)
- 超広帯域無線波(UWB波)を被検者に向けて発信し、反射波の受信信号から前置増幅/検波器によって遅延プロファイルを得、該遅延プロファイルをA/D変換した後、信号処理部で反射波毎に信号強度の時間変動として観測するとともに呼吸波形の急な時間的変化に対応するためにウェーブレット変換によって周波数解析を行って、被検者の呼吸数又は異常呼吸を検出するようにしたことを特徴とする呼吸監視方法。
- 超広帯域無線波発振器と、超広帯域無線波送受信アンテナと、反射波の受信信号を増幅、検波し遅延プロファイルを得る前置増幅/検波器と、遅延プロファイル信号をデジタル化するA/D変換器と、A/D変換された遅延プロファイルから反射波毎に信号強度の時間変動を出力するとともに、呼吸波形の急な時間的変化に対応するためにウェーブレット変換によって周波数解析を行う信号処理部とを有することを特徴とする呼吸監視装置。
