24-Hour Fetal/Maternal Monitoring System Based on Phonocardiogram Analysis

Abstract

The article describes an engineering prototype of the Device for 24-hour monitoring over the functional state of the fetus and mother’s cardiovascular system in the antenatal period of pregnancy. The Device is a hardware and software system that ensures the registration and analysis of fetus and mother’s phonocardiograms with further processing and interpretation. The interpretation process is designed to timely detect conditions that constitute a threat to a fetus. The Device operates as part of a telemedicine network that allows obstetricians-gynecologists managing pregnant women to remotely control their state. The article describes the Device design concept and features of its specific components. The engineering prototype of the Device was used to carry out biomedical tests that confirmed its suitability for 24-hour monitoring over the functional state of fetus and mother’s cardiovascular system in home settings.
