The utility model relates to a fetus ECG machine which can collect body surface signals of a pregnant woman in the mode of non-invasive detection and can separate individual fetus ECG signals from the body surface signals of the pregnant woman. The utility model is formed by orderly connecting a six-core lead wire, a four-passage signal amplifier, a USB interface A/D card, a computer and a printer, wherein two paths of chest lead signals and two paths of abdomen lead signals are coupled in the USB interface A/D card, and the four-passage signal amplifier is connected with the USB interface A/D card which is connected with the computer through a USB cable wire. The utility model is used for monitoring and managing a pregnant woman in the pregnant and puerperal period and the cardiac function and the growth situation of a fetus in real time, and fetus electrocardiosignals can be separated, measured and individually displayed from the collected mixed electrocardiosignals of the mother and the fetus in the mode of non-invasive detection. Therefore, the utility model has no harm and risk to pregnant women and fetuses, and can be repeatedly used many times for a long time. The utility model has the advantages that a fetus ECG is true, stable and complete, the information is rich, and the operation is convenient.
