Fetal heart rate, fetal movement and uterine contraction intelligent monitoring system and method

Abstract

The invention relates to the technical field of maternal and infant monitoring, in particular to a fetal movement and uterine contraction intelligent monitoring system and method. The fetal heart rate, fetal movement and uterine contraction intelligent monitoring system comprises an adhesion layer, a flexible circuit board and a protection layer which are stacked sequentially; the adhesion layer is provided with multiple suckers used for attaching to a belly and a uterine fundus of a pregnant woman, the interior of each sucker is provided with at least one flexible micro pressure sensor, when the sucker is attached to the belly and the uterine fundus of the pregnant woman, the flexible micro pressure sensor is attached tightly to skin of the pregnant woman; pressure to the skin due to cardiac pulsation of the fetus and fetal movement is collected by the flexible micro pressure sensor attached to the belly of the pregnant woman, the pressure to the skin due to the uterine contraction is collected by the flexible micro pressure sensor attached to the uterine fundus of the pregnant woman; the flexible circuit board is used for processing and analyzing a pressure signal collected by the flexible micro pressure sensor, and displaying through display equipment. The intelligent monitoring system can simultaneously monitor the fetal heart rate, the fetal movement and the uterine contraction, the measuring precision is high, and the pregnant woman can be self-monitored at home.

Description

technical field [0001] The invention relates to the technical field of maternal and infant monitoring, in particular to an intelligent monitoring system and method for fetal movement and uterine contractions. Background technique [0002] The content of health monitoring for mothers and babies at home and abroad mainly includes the detection of fetal heart rate and fetal movement frequency. [0003] The detection of fetal heart rate is mostly realized by the principle of ultrasonic Doppler. The Doppler ultrasonic instrument is used to obtain the heart sound signal of the fetus, and the fetal heart rate is calculated according to the heart sound signal to judge the health status of the fetus. However, Doppler ultrasound generally has a problem of radiation intensity. Although the detection amount is very low, it also belongs to the category of destructive detection. If the control is not good, it will cause certain harm to the baby. It is not suitable for frequent and repetit...

AI Technical Summary

Problems solved by technology

This requires pregnant women to manually count according to the perception of the abdomen for a long time, which can neither avoid counting omissions caused by the strength of pregnant women’s perception, nor can avoid the increase in counts caused by gastrointestinal movement noise. This method is time-consuming and laborious, and there is a subjective feeling. Judging the error problem, it is often impossible to get accurate conclusions, which can easily lead to misjudgment

The domestic Doppler ultrasound instrument has relatively simple functions, which can only satisfy simple heart rate calculations, and cannot automatically capture fetal movement signals, making it difficult to make a comprehensive and reliable health status assessment and information feedback for the fetus, especially after 30 weeks

[0004] According to the uterine contraction pressure, the expected date of delivery can be predicted, and there has been little research on the monitoring of pregnant women's uterine contractions
