AngelSounds JPD-200S Bluetooth 4.0 Pregnant Women Home Fetal Doppler Heart Rate Monitor

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.
