FETAL MONITORING DEVICE AND METHODS
First Claim
1. An ultra-wideband (UWB) fetal monitoring system capable of concurrent monitoring of indicators of fetal and maternal health, the system comprising:
- a sensor configured for receiving and transmission of UWB signal data, the sensor comprising at least one antenna; and
a signal processor configured to receive signal data from the sensor and to process the information into a matrix of reflected signals indexed by depth and time, wherein the signal processor is programmed to;
determine at least two waveform patterns from the matrix of reflected signals, wherein a first waveform corresponds to a first maternal anatomical structure and a second waveform corresponds to a first fetal anatomical structure;
identify the first maternal anatomical structure and the first fetal anatomical structure based on pattern recognition of the first waveform and the second waveform; and
extract from the matrix of reflected signals a plurality of indicators of fetal heath and maternal health based on the determination of at least two waveform patterns and the identification of the maternal anatomical structure and the fetal anatomical structure.

Abstract
Described herein are fetal and/or maternal monitoring devices, systems and methods using UWB medical radar. These devices and systems may include a UWB sensor providing high-resolution and reliable simultaneous monitoring of multiple indicators of fetal and/or maternal health, such as fetal heart rate, fetal heart rate variability, fetal respiration, fetal gross body movement, maternal contractions, maternal heart rate, maternal respiration, and other derivative parameters during virtually all stages of pregnancy and during delivery. The sensor allows novel collection of physiological data using a single sensor or multiple sensors to develop individual and aggregate normal motion indices for use in determining when departure from normal motion index is indicative of fetal or maternal distress.
