Special Tips:
The main purpose of Fetal home monitoring is to hear the fetal heartbeat, estimate the frequency of fetal heart beating in one minute, monitor whether the FHR(fetal heartbeat rate) is within the normal range(normal FHR range: 120-160bpm);

Advise pregnant woman to hear 5 to 10 minutes when hearing the FHR each time, and draw a form to record the FHR for inspection;

This model is not expert medical detector, only used to assist to hear the FHR and frequency of fetal heart during gestation. Please use according to doctor's advice and do not replace the conventional pregnancy test, Any questions concerning pregnant woman, please consult the doctor.
