Abstract

The present invention discloses a wearable apparatus for the detection of fetal movement and method thereof. The apparatus presets a corresponding relation between a pregnant woman ECG wave (Electrocardiogram wave) and a fetal ECG wave. The apparatus collects and processes an information of the pregnant woman ECG wave to ensure an information of the fetal ECG wave corresponding to the information of the pregnant woman ECG wave according to the corresponding relation. Thus the fetal movement can be ensured is normal or not according to the information of the fetal ECG wave. Furthermore, the information of the pregnant woman ECG wave and the information of the fetal ECG wave can be transmitted to a user terminal and be analyzed and classified by the user terminal. In the present invention, the pregnant woman does not need to ensure the fetal movement at hospital, being convenient and saving time. The fetal movement is detected without adopting a hand-held apparatus for the detection of fetal movement, but the fetal movement is detected through a wrist of the pregnant. Therefore the pregnant woman is not uncomfortable during the detecting period. And the detection of the fetal ECG wave is more exact because the fetal ECG wave is ensured based on the pregnant woman ECG wave.
