Fetal Monitoring Device and Method

摘要

A fetal monitoring device includes a piezofilm sheet, a first electrode, and a second electrode. A controller is operably connected to the piezofilm sheet, first electrode, and second electrode and receives a biopotential and a piezofilm signal. The controller derives at least one of a maternal heart rate and a uterine activity for the biopotential and derives at least one of a fetal heart rate and fetal motion detection from the piezofilm signal. The controller derives an index of fetal health and operate an indicator to present the derived index of fetal health.

1. A fetal monitoring device, comprising:
a piezofilm sheet; a first electrode; a second electrode; a controller operably connected to the piezofilm sheet, the first electrode and the second electrode, the controller receives an acoustic signal from the piezofilm sheet and a biopotential measured between the first electrode and the second electrode and derives at least one of fetal heart rate and fetal motion detection from the acoustic signal and at least one of maternal heart rate and uterine activity from the biopotential and derives an index of fetal health from the at least one of fetal heart rate and fetal motion detection and at least one of maternal heart rate and uterine activity; and an indicator operable by the controller to present the derived index of fetal health.
