Abstract

Nowadays, the application of FHR monitoring system is increased in obstetric departments. Using this system the FETAL HEART RATE and uterine contraction can be determined. The most important applications are calculation of the FETAL HEART RATE short term variation (STV) and uterine contraction during delivery. The designed system has two main sections; analog and digital. In the analog section using a continuous wave DOPPLER ULTRASOUND, the DOPPLER shift frequency from the blood flow in the heart is detected. Also, a pressure gage circuit measures the degree of the uterine contraction. In the digital section, having digitized the analog DOPPLER shift signal, using a fast FETAL HEART RATE algorithm, the FETAL HEART RATE is estimated. In this algorithm the signal is processed faster and more precise than other proposed algorithms. After FHR estimation and contraction percentage measurement, these data are displayed on an LCD and their variations are plotted using an external printer. Data processing is performed using a high technology digital signal processing chip. Both the analog and the digital sections were constructed and tested separately. An assembly language programming was written to control different parts of the system; the data processing, user interface, display and printer. Technical data that achieved in this project can be implemented for the commercial manufacturing of the device in Iran.
