AngelSounds JPD-100S9 Pregnant Women Home Fetal Doppler Heart Rate Monitor(White)

1. The product is mainly used to detect the sound of the fetal heartbeat (SFH). Fetal heart rate (FHR) is important basis for checking whether a fetus is healthy. Recording the changes in FHR helps detecting signs of fetal hypoxia, fetal distress, fetal umbilical cord around neck, and so on. Fetal monitoring at home includes listening to fetal heartbeat and checking FHR changes, which help greatly increase fertility safety.
2. It is a hand-held, battery powered audio Doppler device used for detecting fetal heartbeats. The patient is an intended operator.
3. The device is ultrasonic fetal heart beat detector, which can detect the Fetal Heart Rate. The built in speaker of the device allows for listen to the fetal heartbeat. The Product normally is applied to fetus of above 16 weeks growth, difference in pregnant mater. The normal range of fetal heart rate: 110bpm-160bpm
