fetal heart doppler

Starting from the 16th week of pregnancy, expectant parents can use home Doppler fetal monitoring devices to monitor fetal heartbeat. The principle is the same as that of medical monitoring equipment for fetal heart rate: by amplifying the fetal heart rate through the Doppler effect, medical staff and pregnant parents can hear the sound of fetal heartbeat more clearly and accurately, and use electronic devices to achieve scientific functions such as fetal heart rate counting and recording.
