A fetal pulse monitor includes an ultrasound crystal. An ultrasound controller is electrically connected to the ultrasound crystal and operates the ultrasound crystal to produce ultrasound signals and receive reflected ultrasound signals. A wireless transmitter is electrically connected to the ultrasound controller. A biocompatible housing at least partially surrounds the ultrasound crystal, ultrasound controller, and the wireless transmitter. A system for monitoring fetal heart rate includes a fetal pulse monitor configured for insertion into a womb of a patient and for attachment to a fetus within the womb. The fetal pulse monitor includes an ultrasound crystal, an ultrasound controller electrically connected to the ultrasound crystal, and a wireless transmitter electrically connected to the ultrasound controller. A patient monitoring device is external to the womb and includes a wireless receiver and a processor that detects instantaneous fetal heart rate from the received ultrasound signal. A graphical display is communicatively connected to the patient monitoring device. The graphical display is operated by the patient monitoring device to present the determined fetal heart rate. |
