A computer simulation conversion method for real-time conversion of fetal ECG signal into fetal fetal sound

Abstract

The invention provides a computer simulation transformation method for transforming fetal electrocardiosignals into fetus sounds in real time, and belongs to the technical field of fetus sound computer simulation noninvasive to pregnant woman. The method is characterized in that by means of segment inputting, batch caching and transforming batch by batch, a segment of fetal electrocardiosignals, extracted from a maternal abdomen, input from a physiological signal database and separated by a fetal electrocardiosignal separation algorithm is input into a computer; a batch of fetal electrocardiosignals to be processed is acquired after batch caching, batch-by-batch extracting and preprocessing; then by means of a linear transformation function batch by batch, the fetal electrocardiosignals are transformed into fetal heartbeat sound signals corresponding to the fetal electrocardiosignal amplitude of each sampling site at equal time intervals; the square-wave pulse signals of fetal heartbeat sounds at equal time intervals are acquired after voltage-frequency conversion and are transformed into fetus sounds at equal time intervals through a loudspeaker. The computer simulation transformation method for transforming the fetal electrocardiosignals into the fetus sounds in real time has the advantages of being easy to operate and accurately recognizing the R waves of the fetus sounds, and can be applicable to the fields of family monitoring of pregnant women, remote monitoring of the health of pregnant women and fetuses and the like after a portable fetus sound monitoring instrument is made.

Description

Technical field: [0001] The invention belongs to the technical field of computer simulation conversion of non-invasive fetal sounds of pregnant women. Background technique: [0002] Fetal heart rate monitoring technology can help clinicians obtain accurate and timely information on the physiological state of the fetus during pregnancy or delivery. Other problems such as fetal distress in the mother's body will be directly reflected in the change of fetal heart rate. The current clinical fetal heart monitoring methods mostly use the ultrasound Doppler method. This method uses the ultrasound probe to be placed in the mother’s abdomen and aimed at the fetal heart. According to the Doppler effect, the fetal heart’s contraction and relaxation are identified, and then The sound of changes in fetal heart activity, that is, fetal fetal sound, is played through the built-in speaker, and the physiological and pathological state of the fetus is monitored through this sound. However, this ...

Problems solved by technology

But this method has the following limitations: 1. The pregnant woman needs to keep still during the measurement process, so it is not suitable for long-term monitoring

2. Studies have shown that long-term exposure of fetuses to ultrasonic radiation will affect their physical fitness after birth
