A method for processing an on-line vital signal capable of stably measuring a fetal electrocardiogram during fetal movement, which is effective during the fetal movement, and its apparatus.

Non-invasive fetal diagnostic methods are provided.

This invention provides compositions and methods for distinguishing fetal from non-fetal male DNA in a human maternal whole blood sample.

In some instances, the systems include both a maternal simulator and a fetal simulator, wherein the physiological conditions of the maternal and fetal simulators are linked to one another.

In practical systems, the fetal well-being information is derived and displayed over time to convey trends in fetal well-being.

Doppler, non-fetal, fetal - Information about the motion of blood in the larger vessels may be

The fetal DNA percentage can be computed by counting reactions with a fetal-specific allele, and correcting the number to account for a statistical distribution among the reactions.

Statistical methods are provided for analyzing the variation of the normalized parameters to determine fetal DNA concentration and the maternal- fetal mixed genotype at various loci.

The invention relates to a device for monitoring foetal status.

The fetal vector electrocardiogram is projected according to the projection direction.

Variations of the device may be used for a fetal repositioning procedure.

The extension socket (102) is actively snap-fitted to the fetal heart monitoring device (2) and the extension socket (102) is electrically connected to the fetal heart monitoring device (2).
