Patient care and management can significantly be improved by the introduction of remote home monitoring. Patients suffering from chronic diseases like diabetes are recommended to collect data such as blood glucose level, insulin doses applied, weight, mobility, daily exercise, blood pressure and others, depending on the stage of their disease and possible (present and/or late) complications. This paper describes a complete system for remote home monitoring and care of patients, the Personalized Intelligent Mobile Health System for diabetic patients. The system is based on a custom designed wireless network, consisting of a main unit and several sensor nodes, connected to the Internet via one of access points within home or working place and an expert system which is accessible through Internet. The mobile unit is the central device for monitoring basic physiological functions measured at the main unit or at any of the sensor nodes, data storage and management and information processing. This device is lightweight and is worn on patient's belt or a pocket in a shirt. It monitors physiological functions such as ECG, heart rate, temperature, breathing rate and physical activity. Our custom made sensors connect to the main unit by a wireless link while peripheral devices from different manufacturers (e.g. glucometer, blood pressure meter) can be connected to the main unit via interconnection devices. While out of wireless network range, the mobile unit stores data on a SD card memory capacity up to 4GB. When it comes in range of wireless network data is automatically transferred to web database over access point connected on internet.
The Web expert system is a user interface for data management, available to patient and patient's physician for overview and decision making, help in disease self-management and for advice. Continuous monitoring enables early detection of any possibly pathological changes and prevention of later complications.
Ratko Magjarević received his Ph.D. in Electrical Engineering in 1994 from the University of Zagreb, Faculty of Electrical Engineering. After his appointment in industry at the Institute of Electrical Engineering “Koncar,“ he joined the Electronic Measurement and Biomedical Engineering Group at the Faculty of Electrical Engineering and Computing, University of Zagreb.
Currently, he is full professor teaching several courses in Electronic Instrumentation and Biomedical Engineering at undergraduate and graduate studies and “Instrumentation in Environmental Protection” at postgraduate studies.
His scientific and professional interest is in fields of electronic and biomedical instrumentation, in particular in cardiac potentials analysis and pacing, in research of new methods for drug delivery based on electropermeabilisation and recently in research of personalised intelligent mobile health systems. He is author or co-author of more than 60 journal or conference papers, several text books and book chapters.
He held the office of the IFMBE Secretary General (International Federation for Medical and Biological Engineering) from 2003 to 2009. In 2009 at the IFMBE General Assembly he has been elected IFMBE President Elect. From 2003 Ratko Magjarevic has been the Editor of IFMBE News, and from 2006 Editor of the IFMBE Proceedings Series. He is also the President of the Croatian Medical and Biological Engineering Society.
