Abstract:

This work undertakes to conduct studies, to design and implement a scalable electronic-computing and telecommunications system that would enable automated complex telemonitoring, at any time and at any place in real time, of chronically ill persons, of aged persons, of high medical risk persons and of those with neuro-locomotor disabilities persons. Its complexity ensues also from the multitude of monitored physical values: electrophysiological (vital) signals, signals for domotic (supervision of domestic utilities, access to a certain site) and the automated analysis of images of subjects’ movements. Furthermore, the system will enable the automated generation of various warnings and alarms, specific to patient’s problems.
The main objective of the project is to make an integrated system made up mainly of the following component parts located in the area of the patient: a personal network of wireless transducers (RPT) to the patient, a network of transducers/actuators for domotic, a concentrating data block and a personal computer (PC). After local processing of signals or images specific to the monitored values, the essential data are transmitted on internet or GSM/GPRS or phone to a database server of the Regional Telemonitoring Center. The personal transducers network (RPT) includes a medical device for vital signs (ECG, pulse, blood pressure, oxygen saturation, body temperature), a movement sensor, a breathing sensor, if the case, all these being provided with radio micro-transmitters, which enable patient’s autonomy of movement. Also, the variant of the mobile subject is approached. In this case, the patient will wear a personal network of transducers, data will be processed by a PDA-type computer (Personal Digital Assistant) provided with GPS localization, and data transmission will be made via the module GSM / 3G of PDA. From the perspective of the application software, data will be correlated on two levels: a local data processing, to the patient, and another at the level of the database server. Hence, the general software architecture will be type client – server, and the project undertakes to develop a SOA – Service Oriented Architecture. The results of data processing will be mainly and at need various alarms locally generated and also sent at a distance to the central server, to the general practitioner or to the specialist doctor, the local ambulance service or the hospital on duty. Other results of the data local processing or server processing will be various medical statistics required for the assessment of the subject’s condition, his therapeutic plan and health financing systems. The implementation of this project will enable persons with various (chronic) disorders and the seniors/the single to be supervised medically, reducing hence the risk of accidents. The end product – the TELEMON system – is a pilot project designed to implement a e-health public service “at any time and at any place”, in real time, for subjects found in care and treatment centers, at home, at work, in holiday, on the street etc.
