Integration of LabVIEW and DAQ Card for Development of Electrogastrogram Simulator

Biopotential signal simulator is a device that mimics the electrical activity of the body organ. Simulators are used in calibration and maintenance to assure the quality and safety factor of the medical devices before using them on the patients. Electrogastrogram or EGG is the biopotential signal generated from the human stomach. This unique signal provides insights about the digestive system by producing normal and abnormal rhythms in case of proper and improper digestion of food respectively. In this paper, an EGG simulator has been designed and developed by integrating LabVIEW and DAQ Card. EGG rhythms during fasting and postprandial period have been simulated. Since collecting EGG data from subjects is a time-consuming and demanding operation, simulating EGG signals is crucial for evaluating newly designed EGG acquisition systems as it reduces the amount of time and money spent on data collection during preclinical trials of newly created devices. The EGG simulator can also be used to simulate certain rhythms, which can improve the accuracy of prediction algorithms used to distinguish between normal and pathological EGG rhythms. The EGG simulator has the potential to be integrated into medical manikins in the future, as it is currently unavailable on the market. It can also be used for testing and optimizing newly created EGG acquisition systems and disease detection algorithms, which will further research and development in the field of gastroenterology.
