Freeplay FHRM

The FreePlay FHRM includes a probe that uses Doppler ultrasound waves to detect the fetal heart. It runs off rechargeable batteries that are inside the device. The batteries may be recharged from three different power sources: mains electricity; manual, wind-up power and solar energy.

The fetal heart can be “heard” on the loudspeaker while the fetal heart rate is shown on the display screen. The fetal monitor is most useful in assessing the condition of the fetus during labour.

The unit features an On/Off Button, LED display screen, flashing heart icon to indicate each heartbeat, loudspeaker, wind-up handle, indicator light that shows power is being generated, connecting lead from monitor to probe, ultrasound probe, and a mains adaptor, power cable, and DC input socket. Weight is <600 grams.

Through a randomized controlled study in Dar es Salaam, Tanzania, it was demonstrated that FHRM provides better perinatal outcomes in comparison to a fetal stethoscope.

Additionally, when evaluating the usability perceptions of midwives, they found barriers for the adoption of this technology, like insufficient training, convenience of use, comfort and limited privacy.

Must not be used on a patient when connected to the main supply.
