Bistos BT-300 Fetal Monitor

Bistos BT-300 Fetal Monitor that measures fetal heart rate(FHR) which may be evaluated to predict fetal status and uterine contraction. BT-300 irradiates ultrasound wave to the abdomen of a pregnant woman, and detects the Doppler frequency signal reflected from the heart of the fetus. The BT-300 analyzes this signal and displays the heart rate by LED. Also, BT-300 provides the sound from the heart of fetus. FHR and UA are displayed continuously at numeric display on the front panel. Fetal heart rate is measured by using a 1MHz ultrasound wave which transmits the burst pulse to the 7 ultrasound sensors about 3.47KHz The BT-300 measures the uterine contraction of a pregnant woman by pressure sensors and displays the numerical values.And the BT-300 prints the heart rate of the fetus and the values of the uterine contractions.
