Bistos BT-770 Patient Monitor with Wifi

Bistos BT-770 Patient Monitor with Wifi is a fetal monitor that measures fetal heart rate(FHR) which may be evaluated to predict fetal status and uterine contraction. BT-300 irradiates ultrasound waves to the abdomen of a pregnant woman and detects the Doppler frequency signal reflected from the heart of the fetus. The BT-770 analyzes this signal and displays the heart rate by LED. Also, BT-300 provides the sound from the heart of the fetus. FHR and UA are displayed continuously at the 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 at about 3.47KHz The BT-350 measures the uterine contraction of a pregnant woman by pressure sensors and displays the numerical values.And the BT-770 prints the heart rate of the fetus and the values of the uterine contractions.
