A New Approach for Testing Fetal Heart Rate Monitors

Abstract

In this paper, a new approach for the periodical testing and the functionality evaluation of a fetal heart rate monitor device based on ultrasound principle is proposed. The design and realization of the device are presented, together with the description of its features and functioning tests. In the designed device, a relay element, driven by an electric signal that allows switching at two specific frequencies, is used to simulate the fetus and the mother’s heartbeat. The simulator was designed to be compliant with the standard requirements for accurate assessment and measurement of medical devices. The accuracy of the simulated signals was evaluated, and it resulted to be stable and reliable. The generated frequencies show an error of about 0.5% with respect to the nominal one while the accuracy of the test equipment was within ±3% of the test signal set frequency. This value complies with the technical standard for the accuracy of fetal heart rate monitor devices. Moreover, the performed tests and measurements show the correct functionality of the developed simulator. The proposed equipment and testing respect the technical requirements for medical devices. The features of the proposed device make it simple and quick in testing a fetal heart rate monitor, thus providing an efficient way to evaluate and test the correlation capabilities of commercial apparatuses.

The Effect of Lost Data on the IoT Platform on the Formation of Fetal Heart Rate Graphs for Remote Diagnostic Purposes

“…There are several studies that discuss fetal doppler including, in 2011 there were Lukas Zach, Vaclav Chud, Jakub Kuz, who discussed the appearance of FHR parameters on CTG using an android application [2] [16]. Heart rate although in this study there is a CTG [17][18] title but the researcher only sends and displays FHR, the researcher concludes that the use of the android application as a medium to display FHR data in the future can be used as a reference for the telemedicine system in monitoring FHR data, but this study has not discussed about lost data that exists when sending and receiving data.…”
