Fetal movement sensor

Abstract

A fetal movement measuring device includes a wearable article to be worn on a pregnant woman's abdomen, plural measurement units, and a mobile device pre-installed with a fetal movement algorithm. The measurement units are provided separately on the outer surface of the wearable article and each include a fetal movement sensor for sensing a dynamic physiological signal of the abdomen and a power supply element for supplying necessary electricity to the fetal movement sensor. The dynamic physiological signals sensed by the fetal movement sensors are received by the mobile device, processed with the fetal movement algorithm, and rid of synchronous signal components. Then, the fetal movement algorithm performs calculation on the remaining signal components to generate fetal movement information, which includes a fetal movement location and a fetal movement magnitude. Thus, each fetal movement is measured in a non-contact manner, and its location, obtained through asynchronous multipoint measurement.

Description

technical field [0001] The invention relates to a measuring device, in particular to a fetal movement measuring device. Background technique [0002] Fetal movement, uterine contraction and fetal heart rate are very important physiological parameters to observe the condition of the fetus during a woman's pregnancy cycle. Fetal movement refers to the activity of the fetus in the uterus. heart rate. Among them, fetal movement is the earliest and easiest signal to detect, and it is also the method most often recommended by clinicians to pregnant women to observe whether the fetus is healthy. Therefore, the pregnant woman handbook also provides a fetal movement recording form. It is hoped that pregnant women can regularly measure fetal movement to ensure fetal safety. However, self-measurement of fetal movement is quite tedious, for example, at 8 weeks of pregnancy, there will be at least 1 fetal movement every 13 minutes, at 20 weeks, the average number of fetal movements is a...

Problems solved by technology

However, this patent still uses patch electrodes to be attached to the skin of pregnant women to detect EMG signals, so there are still situations in which it is easy to cause discomfort and interference to pregnant women.

In addition, the patent case does not disclose how to judge and eliminate non-fetal movement signals caused by the actions of pregnant women, so as to avoid misjudgment
