A central fetus monitoring system is introduced. This system is composed of a central workstation, mother/fetus monitoring inside hospital and family-used fetus monitoring. Only one work station is needed for the whole system, including the sector inside the hospital and the external sector for family-use and other small hospitals. Pregnant women in obstetrics hospitals and homes can be monitored in real-time and all the time at the central workstation. The sector inside the hospital is based on RS-485 bus, while the external sector for family-use is based on public telephone network. Unique techniques were adopted in the fetus monitoring. Part of the key circuits was built in the fetal heart sensor for noise reduction and reliability, and unique algorithm for fetal heart rate detection was designed. Besides, the monitors can operate independently or communicate with the central workstation through RS-485 bus. A remote or family-used monitoring system was designed. The family-used fetus monitor is portable and stable, which can detect doppler sound of the fetus, display the FHR values with its LCD and mark the fetal movements. It can be connected to the central workstation in the hospital througth telephone line if needed. Thus, the information acquired at family side can be monitored in real-time at workstation located in the hospital as if they were in the hospital. Pregnant women and doctors at hospital can talk with each other while monitoring is going on. Built-in chip technology is used and it is an effective solution for remote monitoring of fetus. Computer-assistant diagnosis software was designed. Its functions include automatic evaluation of fetal monitoring curves, chart for delivery process, etc.
