Benefits of technology

[0047]The signal processor may be configured to extract a plurality of indicators of fetal or fetal and maternal health from the matrix. Any of the indicators described above may be extracted. In some variations, the server is configured to extract a plurality of indicators of fetal or fetal and maternal health from the matrix. Thus, extraction from the matrix may be performed at the individual signal processor level, or it may be sent from the patient-side device to a centralized server for processing. Thus,

Embodiment Construction

[0058]Any of the fetal monitoring systems described herein may include one or more UWB sensors for emitting UWB signals and for receiving reflections of the UWB signals and a processor configured to process the reflected UWB signals. The processor may be configured to organize the reflected signals into a matrix indexed by time and by depth into the tissue, or by frequency and depth into the tissue. The processor may also be configured to extract movement information specific to two or more indication of fetal and / or maternal health.

[0059]For example, in some variations, the fetal medical radar sensors described herein include a sensor (or “sensor unit”) with associated electronics and / or logic. The logic may include hardware, firmware, and / or software to perform the functions described herein. The sensor 20 may include a transmitting (Tx) antenna and a receiving (Rx) antenna, or a combined transmitting / receiving antenna. The sensor 20 may communicate in a bidirectional mode with a ...

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.
