SYSTEM AND METHOD FOR FETAL BRAIN MONITORING

摘要

Brain wave response of a fetus in utero is detected through a biosensor electrode connected to a mother's abdomen while a transducer is pulsed with rectangular waves or tone pips to generate pulsed audible sounds at predetermined times to isolate, for each pulsed sound, voltage oscillations corresponding to BAER and convert this to BAER digital data. Apparatus for monitoring fetal brain wave response in utero, comprises a transducer producing pulsed sounds and a biosensor electrode for placement on the mother's abdomen in combination with a pulsing arrangement generating pulsed sounds at predetermined times by pulsing the transducer with rectangular waves or tone pips while an amplifier connected to the electrode amplifies the fetal BAER. An A/D converter converts this BAER data to digital data and a QEEG improves a signal to noise ratio of the digital data using a filtering algorithm and analyzes the digital data.
