Description
Technical Field
The invention relates to the technical field of fetal heart monitoring, in particular to a passive fetal heart monitoring and analyzing method.
Background
During the pregnancy of the pregnant woman, especially in the middle and late pregnancy, various indexes of the fetus are monitored, so that the health condition of the fetus in the uterus can be known, and the abnormality of the fetus can be discovered early. For example, the fetal heart rate can be obtained by monitoring the fetal heart, and whether the fetal heart rate is normal is an important index for judging whether the fetus is lack of oxygen in the mother, so fetal heart monitoring is an important item for monitoring the pregnancy.
Fetal heart monitoring was originally performed using fetal sound auscultation equipment, but has been gradually replaced by doppler ultrasound equipment due to the inability to amplify and record sound signals. The principle of Doppler's ultrasonic monitoring fetal heart is that the probe that can launch the ultrasonic wave is used to fetal heart position transmission ultrasonic wave, when the ultrasonic wave meets the heart of motion and during the reflection, because the frequency of Doppler effect echo can take place slight change, calculates the echo signal and can obtain fetal heart rate to in the use, need find the fetal heart, and use the couplant supplementary, just can obtain better detection effect. At present, the conventional fetal heart monitoring in a hospital is about 20 minutes, and the fetal heart monitoring needs to be carried out in the hospital every other one to two weeks after 30 weeks of pregnancy, so that great inconvenience is brought to pregnant women and family members.
The related art provides a portable electronic fetal heart monitor, and most of the related portable electronic fetal heart monitors use doppler ultrasound monitoring. However, the ultrasonic wave has certain thermal effect and acoustic effect on human tissues, the influence on the health of the fetus is not clear, the time for performing ultrasonic monitoring on the fetus needs to be controlled, the operation is complex, the fetal heart position needs to be accurately found and the optimal effect can be achieved by using the couplant, so that the fetal heart cannot be continuously monitored for a long time, the health information of the fetus cannot be obtained in real time, the couplant is smeared on the abdomen of a pregnant woman, the pregnant woman needs to be cleaned afterwards, and the comfort level is not low enough.
