Performance Comparison Test of Domestically Produced Fetal Doppler Simulators Against Foreign Production

Abstract

Fetal Doppler is an ultrasonic wave-based medical device used to detect and monitor fetal heartbeat. This device is widely used in maternal and child health practices, both in hospitals and other health facilities. However, there have been few studies comparing the quality and accuracy of domestically produced Fetal Doppler devices with foreign products. This study aims to compare the measurement performance between domestically and foreign-produced Fetal Doppler Simulators with variations in bpm settings of 60, 90, 120, 150, 180, and 210. The measurement data were analyzed using statistical methods in the form of averages, standard deviations, correction values,% Error and% Accuracy. Tests were conducted on five fetal doppler units with two different simulators for five consecutive days. The results of the analysis showed no significant difference between the two. The average accuracy value of the foreign-produced simulator was 99.73%, while the domestic production was 99.71%. This shows that the domestically produced simulator has competitive performance and is worthy of being used as an alternative medical device.
