A kind of non-invasive fetal electrocardiogram detection device and electrocardiogram signal data processing method

Abstract

The invention relates to a non-invasive fetal electrocardiogram detection device and a method for processing electrocardiographic signal data, including a front-end device for collecting electrocardiogram and a software system for analyzing and processing electrocardiographic signals. It specifically includes ECG collecting electrodes, analog-to-digital conversion module, wireless communication module, and core processor module. The signal obtained by the front end of the ECG acquisition is transmitted to the core processing module through the wireless communication module, and the steps of ECG signal quality evaluation, preprocessing, maternal ECG signal analysis and fetal ECG signal analysis and processing are completed, and the maternal and fetal ECG signal is obtained. Heart rate information, combined with waveform morphology analysis, is used to assess the health status of the mother and the status of the fetus in utero. The device can realize long-term, dynamic and real-time analysis and processing of fetal signals of pregnant women, and is of great significance for monitoring the health status of pregnant women and fetuses during pregnancy and childbirth.

Description

technical field [0001] The invention relates to a non-invasive fetal electrocardiogram detection device and a method for processing electrocardiographic signal data, belonging to the technical field of maternal fetal electrocardiogram detection. Background technique [0002] Fetal heart monitoring, also known as electronic fetal monitoring, uses fetal heart rate electronic monitors to record fetal heart rate curves and uterine contraction pressure waveforms for clinical analysis and evaluation of fetal intrauterine conditions. At present, the fetal heart rate detector is generally used in hospitals to monitor the situation of the fetus in utero based on the principle of Doppler ultrasound. The fetal heart rate is regulated by the sympathetic and parasympathetic nerves, and the curve of the monitoring graphic formed by tracing the instantaneous fetal heart rate changes can be used to understand the reaction of the fetal heart rate during fetal movement and uterine contraction...

AI Technical Summary

Problems solved by technology

The second is the lack of fetal heart positioning guidance, which is inconvenient to use at home

For fetal heart rate monitoring in the hospital, there are professional medical staff, and the fetal heart rate can be located quickly. However, the home doppler fetal heart rate monitor has no positioning guidance and needs to be identified and judged by the pregnant woman, which is time-consuming and labor-intensive.

The third is the need for couplant, which is inconvenient to use

Coupling agent application, especially in cold weather, will cause a lot of unreal physical sensations

Fourth, the fetal heart rate monitoring time is short

If the fetal heart rate data is only collected for one or two minutes, it is of no value to the doctor

Fifth, there is a lack of a large amount of important data, and there is no value for fetal heart rate monitoring

Six is ​​the potential risk of ultrasound Doppler

At present, the development of wearable family fetal heart rate monitoring in the world is slow, and the detection algorithm for fetal heart rate is not perfect, so the research of wearable fetal heart rate acquisition device is very necessary
