Abstract(in English) Abstract: Fetal monitoring in common clinical practice uses 2 (two) transducers on gravida’s abdomen, one Doppler and the other labor, at each optimal location. In this study we successfully tried to combine them to make single access point transduction of both signals. Our fluid chamber, manually steerable, high incidence angle Doppler transducer is located at, unlike known prior non-steerable design trials, solar plexus or slightly lower place where normally is the optimal location for external labor sensor. At that location our high incidence angle Doppler beam senses the fetal heart located proximity of pelvic cavity. Our feasibility study model worked stably and continuously for hours to yield diagnostic quality of fetal heart rate recording. Keywords: Doppler, Labor, High angle transducer, Steerable, Fluid chamber
