Abstract

The invention discloses an electrode system, and a method and device for acquiring and measuring foetus electrocardiosignal. The electrode system comprises one or more chest electrodes, a first abdomen electrode, a second abdomen electrode, a third abdomen electrode and a fourth abdomen electrode, wherein the chest electrodes are arranged in the chest region above a horizontal tangent line of fundus of uterus of a measured target; the first abdomen electrode, the second abdomen electrode, the third abdomen electrode and the fourth abdomen electrode are separately arranged at an upper abdomen region, a lower abdomen region, a lower right abdomen region, and a lower left abdomen region of the abdomen of the measured target and are located in the uterus contour line of the measured target; the chest electrodes and the abdomen electrodes are separately and electrically connected to an electrocardio module through lead wires; and the electrocardio module is used for receiving electrical signals from the abdomen electrodes and the chest electrodes, performing signal processing and transmitting the processed electrical signals to monitoring equipment. According to the electrode system adopting the electrode position arrangement disclosed by the invention, the abdomen electrodes are separately aligned with positions where the conduction of the foetus electrocardiosignal corresponding to the female parent of the measured target is optimal, so that the check out success rate of the foetus electrocardiosignal can be increased.

Description

technical field [0001] The invention relates to the technical field of fetal electrocardiographic monitoring, in particular to an electrode system, a method and a device for collecting and measuring fetal electrocardiographic signals. Background technique [0002] Surface fetal ECG technology is a non-invasive and simultaneous monitoring of maternal heart rate and fetal heart rate. It puts ECG electrodes on the surface of the mother's body to obtain the mixed ECG signals of the mother and the fetus, and then conducts the mixed ECG signals of the mother and fetus. Filter, identify and separate, and then obtain the mother's ECG signal and fetal ECG signal, and finally analyze the mother's ECG signal and fetal ECG signal respectively to obtain waveform analysis results and heart rate monitoring results. [0003] The fetal ECG signal is transmitted to the maternal body surface through the amniotic fluid and various tissues of the mother’s body and mixed with the maternal ECG sig...
