Abstract

The invention discloses a method and device for the blind extraction of a fetal electrocardiosignal. The method includes the following steps that a pulse signal of a pregnant and a mixed electrocardiosignal of the abdominal wall of the pregnant are collected at the same time; the pulse signal and the electrocardiosignal are pre-processed; by means of the constrained NMF blind signal separation mode, the pre-processed pulse signal is used for eliminating a pregnant electrocardiosignal in the pre-processed mixed electrocardiosignal, and the fetal electrocardiosignal is obtained. According to the method and device for the blind extraction of the fetal electrocardiosignal, the more accurate fetal electrocardiosignal can be obtained, and experts can thus more conveniently analyze and diagnose the fetal electrocardiosignal, timely give feedbacks to the pregnant and family members and provide professional advice and guidance, so that the pregnant and the family members can better protect the healthy growth of a fetus.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to a method and device for blindly extracting fetal ECG signals. Background technique [0002] At present, with the improvement of people's living standards, people pay more and more attention to the health of the fetus. The fetal electrocardiogram is an important method of fetal monitoring and an important method to detect the health of the fetus in the womb, which can reflect the full picture of the fetal heart. The so-called fetal electrocardiogram refers to the complete waveform of the fetal ECG signal after the interference noise is eliminated. With the fetal electrocardiogram, not only the fetal heart rate can be known, but also the ST segment, PQRS time limit and other parameters can be known, and some of the fetus can be found in time Pathological conditions: intrauterine hypoxia, fetal arrhythmia, fetal arrhythmia, premature fetal heart beats, fetal distress, ...
