MULTISENSOR DOPPLER SYSTEM FOR MONITORING FETAL BEHAVIOR

Purpose: The purpose of our work was to develop a portable Doppler system able to monitor different fetal rhythms (cardiac, respiratory, rest/activity), and to follow their changes during external or maternal stimulation as well as in pathological conditions. One of the final objective is to use this system both in clinics and for tele medicine. Methods and Materials: We developed a new pulsed Doppler system connected to 12 separated captors which can be fixed on the maternal abdomen through a supple probe holder. Each captor detects Doppler signals in 5 different depths positioned between 2 and 15 cms. The back…
