Abstract

The invention provides an integrated patch for the non-invasive monitoring of a laboring woman. The patch incorporates biopotential electrodes for sensing fetal ECG and EMG indicative of myometrial activity. The patch also incorporates a processor for extracting labor activity and fetal heart activity after filtering out maternal ECG from the composite biopotential signal present on the abdomen of the pregnant woman. The fetal monitor patch is thin, flexible, and incorporates a battery and biopotential amplifier network. In the preferred embodiment, the patch is disposable and worn continuously during labor or later stages of pregnancy. In a hospital embodiment for intrapartum monitoring, the patch wirelessly transmits fetal heart activity and myometrial activity to a bedside monitor or a remote monitoring station.
