Separating apparatus and method of fetal ECG from maternal abdomen ECG

摘要

The present invention relates to a device and method for separating fetal ECG from a maternal electrocardiogram detected in a single channel from that of the fetal electrocardiogram from the separation apparatus and method maternal abdominal electrocardiogram, more specifically maternal abdomen. ; Maternal fetal ECG single channel separation method of the electrocardiogram from the abdomen of the present invention is a data input step of initiating a data input abdominal electrocardiogram to detect the maternal abdomen in a single-channel ECG at the maternal abdomen through the A / D converter; Separate vector presence determination step of determining whether there is separation vector; If separation vector is not present, a predetermined period of time from the signals received from the A / D converter's meudeu pseudo Wigner-Ville distribution when applying the (SPWVD) function - after reconfiguring a multi-dimensional signal in the frequency domain, the independent Vector set of steps separated by applying the element Analysis (ICA) that separate vector set; If separation if the vector is present, the switch meudeu pseudo Wigner from the signal received from the A / D converter for a predetermined time - multi-dimensional signal reconstruction step for reconstructing a multi-dimensional signal in the frequency domain - when applied the bill distribution (SPWVD) function .; A multi-dimensional signal reconstructed in the reconstruction step, the multi-dimensional signal, bit detection step of multiplying the vector separation, detecting a bit (R point, heart rate) of a fetus ECG; And calculate the fetal heart rate and fetal ECG template configuration steps to configure the fetal ECG templates; And it characterized by comprising a. ; Single channel abdominal ECG, fetal ECG separation, independent component analysis, separation vector, fetal health monitoring
