System for monitoring fetal status
InactiveUS20040082842A1Facilitate easeData is delayedElectrocardiographySensorsReference databaseThe Internet
During childbirth, trauma to the infant can readily arise, ultimately resulting in fetal hypoxia, academia, and brain damage. Such unfavorable conditions can be best ascertained by real-time monitoring of the fetus' blood-oxygen level, heart rate monitoring, EKG and EEG waveforms. This invention describes a system of monitoring devices to implement such goals and maximize the potential welfare of the fetus. It furthermore allows the formation of a reference database that can correlate intrapartum events from prior births. The embodiments utilize a small-diameter sensor inserted into the birth canal through a tubular insertion rod. Through wire, fiber optics, and or using a radio frequency link, fetal monitor data can be analyzed, compared to existing data base, and or transmitted via internet. This patent details various apparatuses that allow important life-sign parameters of a fetus to be continuously monitored.

ActiveUS20050251044A1Less interferenceOrgan movement/changes detectionHeart/pulse rate measurement devicesSonificationBeam steering
A continuous, non-invasive fetal heart rate measurement is produced using one or more ultrasonic transducer array patches that are adhered or attached to the mother. Each ultrasound transducer array is operated in an autonomous mode by a digital signal processor to obtain data from which fetal heart rate information can be derived. Each ultrasonic transducer array patch comprises a multiplicity of subelements that are switchably reconfigurable to form elements having different shapes, e.g., annular rings. Each subelement comprises a plurality of interconnected cMUT cells that are not switchably disconnectable. The use of cMUT patches will provide the ability to interrogate a three-dimensional space electronically (i.e. without mechanical beam steering) with ultrasound, using a transducer device that is thin and lightweight enough to stick to the patient's skin like an EKG electrode. The ultrasound device can track the fetal heart in three-dimensional space as it moves due to the mother's motion or the motion of the unborn child within the womb.
