Abstract

A portable apparatus for the non-invasive, simultaneous, self-testing of fetal and maternal signals which comprises: a user display means to indicate that the device is operational; an ultrasonic means connected to the device for detecting fetal heart rate; a detection means connected to the device for detecting a maternal input signal; wherein the device has signal processing means for simultaneously processing fetal heart rate and maternal input signals, the signal processing means having a peak detection means for detecting the peak value of the fetal heart signal; and a communication linking means for the simultaneous transmission of fetal heart rate and maternal input data to a remote output device.
