Handheld Fetal Doppler

The Handheld Fetal Doppler is a compact, portable ultrasound device designed for non-invasive detection and monitoring of fetal heart rate (FHR) during pregnancy. It uses the Doppler ultrasound principle to detect fetal cardiac movement and convert the signal into audible fetal heart sounds, with digital models also displaying the fetal heart rate on screen. Its lightweight handheld design makes it useful for antenatal clinics, maternity wards, hospitals, obstetric departments, community healthcare and other prenatal-care settings. Professional handheld fetal Dopplers commonly incorporate an ultrasound probe, digital display, built-in speaker and battery-powered operation.
