Doppler,FHR detector,w/access

Ultrasonic fetal heart detectors are low-cost devices used in a variety of healthcare settings to provide audible and visual information about the fetus. The primary purpose of the fetal heart detector is to provide quick reassurance of fetal well-being to both the mother and the healthcare worker. Certain conditions, such as vaginal bleeding or lack of fetal movement, can cause anxiety in the mother, making her question the health of her unborn baby. Ultrasonic fetal heart detectors can easily detect fetal heart motion throughout the pregnancy, starting as early as 8 weeks. The fetal heartbeat cannot be heard with an obstetric stethoscope until 24 weeks after conception.
