PROBLEM TO BE SOLVED: To provide a fetal monitoring system which smoothens a process for monitoring the heart rate of a baby who has not born yet, and a fetal monitoring method.SOLUTION: The fetal monitoring system 10 includes: an AECG(Abdominal ElectroCardioGram)/PCG(PhonoCardioGram) sensor 12 which generates an AECG/PCG signal 30 in response to monitoring of a fetal heart a US(UltraSound) transducer 14 which generates a US signal 32 in response to the monitoring of the fetal heart and a computer 40 which assess the quality of an AECG/PCG signal 30 and compares the assessed quality of the AECG/PCG signal 30 with a selectable threshold value. The computer 40 is configured to disable the operation of the US transducer 14 and process the AECG/PCG signal 30 to provide a fetal heart rate estimated value as long as the assessed quality of the AECG/PCG signal 30 exceeds the selectable threshold value. The computer 40 is configured to enable the operation of the US transducer 14 and process the US signal 32 to provide a fetal heart rate estimated value only when the assessed quality of the AECG/PCG signal 30 is equal to or less than the selectable threshold.COPYRIGHT: (C)2011,JPO&INPIT【解決手段】 システム(10)は、胎児心臓のモニタリングに応答してAECG/PCG信号(30)を生成するAECG/PCGセンサ(12)と、胎児心臓のモニタリングに応答してUS信号(32)を生成するUSトランスデューサ(14)と、AECG/PCG信号(30)の品質を評価して、AECG/PCG信号(30)の評価された品質を選択可能なしきい値と比較するコンピュータ(40)とを具備する。コンピュータ(40)は、AECG/PCG信号(30)の評価された品質が選択可能なしきい値を超えている限り、USトランスデューサ(14)を動作不能にし、胎児心拍数推定値を提供するためにAECG/PCG信号(30)を処理する。AECG/PCG信号(30)の評価品質がしきい値以下である場合だけ、USトランスデューサ(14)を動作可能にし、胎児心拍数推定値を提供するためにUS信号(32)を処理する。【選択図】図1
