Abstract:
An apparatus for monitoring fetal positions and fetal movements is provided. The apparatus includes a plurality of sensors, a signal pre-processor, a signal post-processor, and a fetal position judging processor. The sensors are attached on the abdomen of a maternal body to provide at least three measuring leads. The signal pre-processor receives a plurality of sensing signals from the sensors, and the signal pre-processor reduces noises in the sensing signals and amplifies the sensing signals to output a plurality of characteristic sensing signals. The signal post-processor receives the characteristic sensing signals from the signal pre-processor and separates out a plurality of fetal electrocardiograms (FECGs) corresponding to the leads. The fetal position judging processor analyzes the FECGs to obtain a characteristic waveform for each of the FECGs or directly calculates a fetal heart axis vector with respect to a front-side coordinate of the maternal body according to the FECGs.
