Foetal Doppler system

A foetal Doppler system is a portable, hand-held device that uses ultrasound technology to detect and monitor the heartbeat of a developing foetus during pregnancy. It consists of a main unit with a display and controls, connected to a probe that is placed on the mother’s abdomen to pick up and amplify foetal heart sounds, which are then heard through a speaker or headphones.

These devices are typically supplied as non-invasive diagnostic tools for use in clinical settings or by expectant parents at home, depending on the model and intended use. They are regulated as medical devices based on their function and risk profile, with requirements varying by jurisdiction, but all are designed to provide audible foetal heart rate information without emitting ionizing radiation or requiring invasive procedures.
