An unique equipment based upon the ultrasonic Doppler shift technique is used for the early detection and diagnosis of pregnancies. A high-frequency ultrasonic signal is reflected back from the foetal heart which observes a shift in its frequency and is proportional to the velocity of the blood. the resulting audio signal is a characteristic of the foetal heart activity.

This compact & portable equipment is composed of advanced electronic components to ensure higher reliability and long life along with noise free operation. It has a low current drain which ensures long life of the battery which is easily replaceable.
