It is a Antepartum Fetal Monitor measuring FHR and UC. It enables a woman in childbed to indicate fetal movement point by pushing event marker button by herself when she feels that. BT-300 indicates FHR as numeral by irradiating ultrasound at the abdomen, abstracting doppler frequency of heart beat cycle from the signals reflected from fetal heart, outputting FHR change as a sound, and analyzing these signals. Besides, you can measure UC by using pressure sensor, indicate, and print the data of FHR and UC.
