A wireless fetal heart monitoring device, including sequentially connected ultrasonic transmitting module, ultrasonic transducer, ultrasonic demodulation module and wireless communication module, which is composed of ultrasonic transmitting module, drive ultrasonic transducer generates ultrasonic, ultrasonic transducer and receiving ultrasonic echo signal and acoustic electric conversion of the ultrasonic echo signal of ultrasonic echo, telecom after the input to the ultrasonic signal processing module of demodulation demodulation to extract fetal cardiac signal and a wireless receiving device by wireless communication module of the fetal heart rate signal transmission to the host of fetal monitoring. Because the invention structure cleverly uses wireless communication technology and Doppler ultrasonic drive and demodulation technology of the combination, the fetal heart beat signal acquisition device and the monitoring computer are separated, and the pregnant women are not restricted by the monitoring host machine to ensure effective, can freely carry out activities.
