What are Fetal Dopplers/Baby Heartbeat Monitors?

Fetal Dopplers, also known as Foetal Dopplers, Ultrasound monitors and Baby heartbeat monitors, are small hand-held devices that allow you to hear your baby's heartbeat in the womb while pregnant. Our range of doppers are used by mothers and professionals in the Health Service all over the world.

Dopplers have been used for over forty years and have proven to be completely safe. Our Dopplers are CE certified, meaning that they have been passed for sale and hire across Europe. Our manufacturers are professional medical equipment producers who own the ISO9001:2000 management certificates. All products are strictly manufactured encompassing a rigorous quality assurance process.

How are Fetal Dopplers used?

Firstly, ultrasound gel is placed on your pregnancy bump to produce a clearer sound. The doppler probe is then placed upon your bump and sends out waves. These waves bounce back when they detect the baby and are picked up again by the Doppler probe. The waves are then sent to the Doppler's speaker so you can clearly hear your baby's heartbeat.

Why use a Doppler?

Baby Dopplers can really help to reduce anxiety during pregnancy, especially in the months before you can feel the baby moving. In between visits to the midwife/doctor and hospital ultrasound scans, Dopplers can provide reassurance and peace of mind quickly and easily. The Doppler is not intended to replace medical advice and if you have any concerns at all regarding your pregnancy, you should always talk to your midwife or doctor.

Lots of our customers use Dopplers to let other members of the family share in the experience of pregnancy - it can be a really nice way to involve partners, young brothers/sisters and other family members by providing an opportunity to hear your baby's heartbeat and other sounds in the womb.

How early can the Doppler pick up the fetal heartbeat?

Our Dopplers work from 12 weeks, but have been known to pick up a baby's heartbeat as early as 6 weeks old. There are a number of cheaper 'Baby listeners' for sale which do not use Doppler ultrasound but instead simply amplify normal sounds from the abdomen. The sound quality from these other devices is very poor and often nothing can be heard until at least 25-30 weeks of pregnancy, leading to some very unhappy customers.

How does Ultrasound work?

Ultrasound is a medical detection technique that uses high frequency sound waves and their echoes. The technique is similar to the method used by bats, whales and dolphins, as well as SONAR used by submarines. Ultrasound devices transmit sound pulses into your body using a probe, which are reflected back to the probe once they come across an object. The time taken for the pulse to get returned is translated into a picture or sound.

Why do I need Ultrasound Gel?

Applying a layer of ultrasound coupling gel between the doppler sensor and tummy can ensure a clear signal for detecting the fetal heart beat. Doppler sound waves do not travel easily through the air and so without the use of coupling gel, high interference prevents a clearly audible sound. Our Dopplers come with a 50g tube of ultrasound gel. You can order more from our website at any time by using our Order page
