Development of a web-based system for interfacing a portable Bluetooth vital sign monitor

Nowadays telemedicine has become increasingly pervasive with the use of wearable sensors and miniaturized devices to monitor vital signs in patients at home and in nonstructured places. Various telemedicine system architectures for remote monitoring of vital parameters have been proposed, also given the increase in population aging. In this paper the implementation of a web-based telemedicine solution with an Android app for a medical device, Checkme Pro, is presented. The proposed solution permits to download data to the developed Android app exploiting the Bluetooth connectivity of the medical device, that is a certified multi-parametric vital sign monitor, and to manage their presentation to users. The Android app permits to view data and measurements and store them in the database, while the developed web app, in addition to data visualization, permits to visualize graphic trends of different vital signs by querying the database. The functionality that allows visualization of the time trends of vital parameters is of enormous interest for telemedicine applications ensuring greater patient safety and a better understanding of the patient’s health situation. Then a validation of the telemedicine system has been done to test the correctness and consistency of the data stored in the Android app, saved in the database, and displayed in both apps.
