<br />Baby Sound A Pocket Fetal Doppler is a hand held equipment for detecting Fetal Heart Rate(FHR) which is specially designed for family of pregnant women to conduct daily detection of FHR by themselves. Pregnant women can operate by themselves to hear fetal heart sound and calculate FHR to realize the purpose of pre-monitoring and fetus caring.
<br />
<br />Main Features
<br />
<br />  The probe and main units integrated together
<br />
<br />  Delicate and compact design, portable to use
<br />
<br />  Particular 2 Headphone Sockets design can let expectant mother and father hear the fetal heart sound together
<br />
<br />  High sensitive doppler probe 
<br />
<br />  Low ultrasound output intensity, much lower than the relative government standard and with high safe quality
<br />
<br />  Low power consumption, two AAA size batteries can last more than 8 hours for continuous use (depend on battery type and volume)
<br />
<br />  Can be connected to a computer or recorder to record the fetal heart sound with recording cable
