FHR Doppler Detector With Accessories
Product Code : EL-MDE-10856
Quick answer: The FHR Doppler Detector with Accessories is a handheld foetal doppler that picks up the foetal heartbeat with a 2 MHz continuous ultrasound transducer, shows foetal heart rate (FHR) on a backlit LCD and plays the heart sounds through a loudspeaker. It is used for routine antenatal checks. Lab Exports manufactures it in Delhi for hospitals, clinics and medical colleges.

How the foetal doppler works
The transducer sends a continuous 2 MHz ultrasound beam into the abdomen and receives the echoes. Moving structures, chiefly the beating foetal heart, shift the frequency of the returning sound (the Doppler effect); the unit turns that shift into an audible heartbeat and counts it to display the foetal heart rate.
Midwives, nurses and doctors use the detector at routine antenatal visits to confirm foetal heart activity and check the rate. Because it is handheld and battery powered, it works equally well in a hospital clinic, a rural health post or on home visits.
- Apply ultrasound gel to the transducer face.
- Place the transducer low on the abdomen and angle it slowly until clear heart sounds are heard.
- Adjust the volume, or connect a headset for private listening.
- Read the FHR on the display, then wipe the transducer and return it to its holder.
