Description

Technical Field

[0001] This invention relates to the field of fetal heart rate monitoring technology, specifically to a wearable fetal heart rate monitoring device and its usage method. Background Technology

[0002] Fetal heart rate is the heartbeat of the fetus. Fetal heart rate monitoring uses the principle of ultrasound to monitor the condition of the fetus in the uterus. It is the main detection method to accurately assess the condition of the fetus in the uterus. Since the fetal heart rate is regulated by the sympathetic and parasympathetic nervous systems, the monitoring graph formed by recording the instantaneous changes in the fetal heart rate can effectively understand the fetal heart rate response during fetal movement and uterine contractions, so as to infer whether the fetus is hypoxic in the uterus.

[0003] A search revealed a wearable fetal heart rate monitoring device and system in Chinese patent application publication number CN218458100U. The wearable fetal heart rate monitoring device described in the patent document uses a secondary strap that can be placed above the pregnant woman's protruding abdomen to assist in fixing the main strap and prevent the main strap from shifting down due to the pregnant woman's movements, thus affecting the accuracy of the fetal heart rate monitoring data.

[0004] However, to maintain the accuracy of fetal heart rate data collection, it is necessary to maintain the fetus's activity within the mother's body. This requires monitoring at a certain fetal movement frequency to improve data accuracy. This can be achieved by using sound stimulation or stroking massage to increase fetal activity frequency. However, this wearable fetal heart rate monitoring device cannot automatically wake the fetus by gently stroking the pregnant woman's abdomen to increase fetal movement frequency. Therefore, further improvements are needed to enhance the accuracy of fetal heart rate data collection. Hence, a wearable fetal heart rate monitoring device and its usage method are proposed.
