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

Abstract

The invention relates to a non-invasive fetal electrocardiogram detection device and an electrocardiogram signal data processing method. The device comprises an electrocardiogram acquisition front-enddevice and an electrocardiogram signal analysis processing software system. It includes ECG collector, analog-to-digital conversion module, wireless communication module and core processor module. The signal obtained by the ECG acquisition front end is transmitted to the core processing module through the wireless communication module, The ECG signal quality evaluation, pretreatment, maternal ECGsignal analysis and fetal ECG signal analysis are completed, and the heart rate information of mother and fetus is obtained. Combined with waveform morphology analysis, the maternal health status andfetal intrauterine status are evaluated. The device can realize the long-term, dynamic and real-time analysis and processing of fetal signals, which is of great significance to the monitoring of maternal and fetal health during pregnancy and parturition.

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...
