The Design of the Wireless Fetal Heart Monitor Based on ZigBee

Fetal heart monitoring is one of the important means of prenatal diagnosis, which can effectively prevent fetal asphyxia, reduce the incidence of various complications and the mortality of the fetus. Therefore, this paper introduces the design of the wireless fetal heart monitor based on ZigBee. The fetal heart signal is converted into a weak electrical signal by the sensor, and then processed after conditioning, A/D conversion, and then transmitted to the terminal through the ZigBee network. When the fetal heart data is abnormal, an alarm is issued, and the abnormal condition of the fetus can be found in time. It has broad application prospects in clinical practice.
