    • An apparatus and method for detecting the heart rate of a fetus. The apparatus includes three detectors detecting heart beats of the fetus, each detector including at least two electrodes detecting ECG signals, the detectors being positioned on an abdomen of a mother in use. The apparatus also includes a processor coupled to the detectors, the processor being adapted to process the ECG signals received from the detectors and determine a heart rate of the fetus. The method of determining the heart rate of the fetus includes determining a position of the fetus within a womb, placing the detectors on an abdomen of the mother, monitoring the ECG signals obtained from the detectors for a predetermined length of time, and processing the ECG signals obtained from the detectors positioned on the abdomen of the mother to determine heart beats of the mother.
    • 一种用于检测胎儿心率的装置和方法。 该装置包括检测胎儿心跳的三个检测器,每个检测器包括检测ECG信号的至少两个电极,检测器位于正在使用的母亲的腹部上。 该装置还包括耦合到检测器的处理器,该处理器适于处理从检测器接收的ECG信号并确定胎儿的心率。 确定胎儿心率的方法包括确定胎儿在子宫内的位置,将检测器放置在母体的腹部上,监测从检测器获得的ECG信号达预定时间长度,以及处理ECG 从位于母亲腹部的检测器获得的信号,以确定母亲的心跳。

    • Fetal behaviour is monitored by receiving ECG data from a set of electrodes attached to a materrial body. A waveform pre-processor identifies a succession of fetal ECG complex waveforms within the received data and a waveform processor determines differences in the processor succession of fetal ECG complex waveforms over time. An event logger determines from the determined differences a number of fetal movements during the period of time. Fetal spatial presentation and/or position within the uterus may also be determined from fetal ECG data acquired from a plurality of electrodes positioned on the maternal abdomen in a predetermined configuration. A number of fetal ECG complex waveforms are identified within the data, and each of the waveforms is compared with a set of predetermined fetal ECG complex templates ascribed to the predetermined electrode configuration to determine a template that best matches the identified fetal ECG waveforms.
    • 通过从连接到物质体的一组电极接收ECG数据来监测胎儿行为。 波形预处理器识别接收到的数据中的一系列胎儿ECG复杂波形,并且波形处理器确定随着时间的推移,胎儿ECG复杂波形的处理器连续性的差异。 事件记录器根据所确定的差异确定一段时间内的胎动。 胎儿空间呈现和/或子宫内的位置也可以从以预定配置从位于母体腹部的多个电极获取的胎儿ECG数据确定。 在数据内识别出许多胎儿ECG复杂波形,并且将每个波形与归因于预定电极配置的一组预定胎儿ECG复合模板进行比较,以确定与所识别的胎儿ECG波形最佳匹配的模板。
