PROBLEM TO BE SOLVED: To provide a respiratory organ and circulatory organ monitoring device that can measure a respiratory rate, cardiac rate, or the like without restraint nor contact by reducing noise at a living body.SOLUTION: A respiratory organ and circulatory organ monitoring device comprises: transmission means for transmitting a microwave to a subject living body reception means for receiving a modulated microwave that has gone through amplitude modulation by going through the living body placed at an opposite position to the microwave radiation means via the subject living body phase comparison means for obtaining a modulated signal by cancelling out a non-modulation carrier component of the microwave transmitted by the transmission means from the received modulated microwave and monitoring means for displaying a respiratory change in the subject living body or a blood flow change in the subject living body from the modulated signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 生体において、ノイズを少なくして無拘束でしかも非接触で呼吸数や心拍数等を計測することができる呼吸器・循環器モニター装置を得る。【解決手段】 被検生体に対してマイクロ波を発信する発信手段と、マイクロ波発射手段に対して被検生体を介した対向位置に配置され生体を通過した振幅変調を受けた変調マイクロ波を受信する受信手段と、受信された変調マイクロ波に対して発信手段で発信されたマイクロ波の無変調キャリア成分を相殺して変調信号を得る位相比較手段と、変調信号から被検生体の呼吸変化又は被検生体の血流変化を表示するモニター手段とを備えたものである。【選択図】 図1
