Pregnancy and birth real-time monitoring device and method

Abstract

The invention provides a pregnancy and birth real-time monitoring device and a pregnancy and birth real-time monitoring method. The pregnancy and birth real-time monitoring device comprises a fetus information acquisition unit, a three-axis acceleration sensor attached to the back and waist of a mother body, a signal processing unit and a control unit, wherein the fetal information acquisition unit comprises an electrocardio reference electrode attached to the back and waist of the mother body and an electrocardio electrode array attached to the abdomen of the mother body; and / or the fetal information acquisition unit comprises a sound sensor which is attached to the central position of the abdomen of the mother body and is used for acquiring fetal heart sound signals; the output ends of fetal electrocardiogram electrodes, the sound sensor and the three-axis acceleration sensor are connected to the signal processing unit, and the output end of the signal processing unit is connected with the control unit. The pregnancy and birth real-time monitoring device adopts multiple types of sensors to monitor the fetus in real time, can objectively and accurately monitor the fetal movement intensity, the fetal movement frequency, the fetal movement type, the fetal heartbeat intensity and the like, and can harmlessly monitor the fetal movement intensity, the fetal movement frequency, thefetal movement type, the fetal heartbeat intensity and the like for a long time in real time at home or in hospitals.

Description

technical field [0001] The invention relates to the field of medical maternity, in particular to a real-time maternity monitoring device and method. Background technique [0002] At present, prenatal and postnatal care is an important national policy of our country, and monitoring technology during pregnancy is of great significance to ensure the safety of mothers and babies. Especially now that the country has fully liberalized and adopted various policies to encourage the second child, the number of elderly pregnant women has increased sharply, and pregnancy monitoring technology has become more prominent and important. Therefore, methods and devices for non-invasive, harmless, long-term real-time monitoring of the health status of fetuses and mothers are particularly important. [0003] At present, there are many studies on fetal movement, because fetal movement is an important indicator of fetal safety in clinical practice, and it has very important clinical significanc...

Problems solved by technology

Subjective counting needs to be counted by pregnant women themselves. In practice, due to the limited medical knowledge of most pregnant women and the inability to concentrate for a long time, the counting error will be relatively large; although the Doppler ultrasound monitoring method is accurate, it needs to be carried out in a hospital and requires Professional operation, long-term operation has a negative impact on the fetus, and is not suitable for long-term monitoring in hospitals and at home; methods based on sensor arrays such as piezoelectric sensors and acceleration sensors need to fix the sensors at certain positions on the mother's abdomen, Moreover, different fixing methods will have different effects on the accuracy of fetal movement monitoring, and it is even difficult to operate in practice.
