Wireless Real-Time Electrogastrography Monitoring System

Gastrointestinal (GI) diseases are one of the rising issues in medical field from the past two decades. The incidence and prevalence rates have shown a notable rise in these conditions, thereby leading to an increase in morbidity and mortality rate. The principle aim of this study is to design and develop a system that can acquire signals precisely and non-invasively from the abdominal skin over the stomach and share the obtained results to the patient mobile wirelessly. This technique enables the user to monitor their gastric condition effortlessly. This standalone system, for detecting various abdominal disorders incorporates the technique of Electrogastrography (i.e.,) recording gastric signals non-invasively using surface electrodes. The proposed real-time gastric recording and monitoring system is designed using Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software in addition to the initial analog circuitries. The entire system is enclosed in an elastic belt to make it wearable for different abdominal torsos. The real-time data acquired is shared with the patient mobile using National Instruments (NI) Data dashboard application mobile application. On the other hand, the data recorded from the system is analyzed in Matrix Laboratory (MATLAB) using moving average algorithm to obtain precise electrogastrographic envelopes. The gastric signal recording is obtained from ten healthy individuals by following the developed experimental protocol in postprandial session. The data obtained is used in evaluating and quantifying the gastric slow wave propagation in the individuals by extracting the signal features in temporal and frequency domains. The obtained results prove the efficiency of the proposed design, with the fixed electrode position making the system user-friendly.
