Pocket Fetal Doppler for Convenient Fetal Heart Rate Monitoring
The Pocket Fetal Doppler is a hand-held fetal heart rate detection device engineered for expectant mothers, clinicians and midwives who need quick and reliable FHR monitoring. Designed with a compact, lightweight body and a high-sensitivity magnetic Doppler probe, the system clearly detects fetal heart sounds from pregnancies of more than 12 weeks and displays the measured FHR value and waveform on a bright 1.77″ LCD screen.
With simple one-handed operation, dual sound output through a built-in speaker or external headphones, battery level indication and intelligent auto shutdown, the device is perfectly suited for daily self-checks at home as well as routine monitoring in hospitals, clinics and community healthcare centers.
