    • 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.

    • 要解决的问题:提供胎儿监测系统,其平滑用于监测尚未出生的婴儿的心率的过程和胎儿监测方法。 胎儿监测系统10包括:AECG(腹部电加热器)/ PCG(PhonoCardioGram)传感器12,其响应于胎儿心脏的监测而产生AECG / PCG信号30; 美国(UltraSound)换能器14,其响应于胎儿心脏的监测而产生美国信号32; 以及评估AECG / PCG信号30的质量并将所评估的AECG / PCG信号30的质量与可选择的阈值进行比较的计算机40。 计算机40被配置为如果AECG / PCG信号30的评估质量超过可选择的阈值,则禁用美国传感器14的操作并处理AECG / PCG信号30以提供胎心率估计值。 计算机40被配置为仅当AECG / PCG信号30的评估质量等于或小于可选择阈值时才能使美国换能器14的操作并且处理美国信号32以提供胎心率估计值。 版权所有(C)2011,JPO&INPIT
