U-R-SAFE project aims to develop a telemedicine concept for medical care of elderly people and a technology platform, which enables patients to be treated and monitored at home.
At the first phase of the project medical procedures and guidelines will be formed and later validated by testing them in practice in a hospital environment as well as in a home environment. These results, which include information on parameter monitoring, alarm generation, medical assistance, patient selection, etc., will serve as a basis of a technological system specification for the technology platform.
The concept is to have the elderly person wear medical measuring devices, all connected via short range Wireless Personal Area Network (WPAN) to a central, portable electronic unit, the Personal Base Station. The short range wireless connection will be done using the Ultra Wide Band technology. It allows to:
- Receive and preprocess the measured medical data, which have been sent from the measuring devices
- Send the pre-processed data to the external service:
- Via the wireless public Network (GPRS, UMTS and/or GEO satellites), when the elderly person is out of home – in particular the use of the Eutelsat system is planned.
- Via the Fixed Access Network (e.g. telephony, cable, wireless), when the elderly person is at home.
- Communicate with simple sentences with the patient and extract information, (particularly valuable in emergency situations).
- Establish direct and hands-free communication between the patient and the external service and /or a medical doctor through the public wireless network (GPRS and UMTS), when this is required.
It is worthwhile to note that at home two Wireless Networks will be interconnected. The first is the Wireless Personal Area Network (WPAN) worn by the person. The second is the wireless indoor LAN, installed in the house or Hospital, which allows the Personal Base Station to communicate via a Gateway to the Fixed Access Network using radio waves.
A commercial miniaturized ECG sensor will be integrated with the wireless platform. On top of that, a wrist-portable (bracelet) SpO2 sensor will be developed and integrated with the present technology. The third sensor to be integrated in the platform is the speech itself, which is considered as an important source of information: thanks to a local dialog between system and patient, information can be gathered in complement to the data measured by the various sensors.
A field trial will be organized within the project including two campaign, sized to demonstrate the functionality of the complete system. The trial will be done in the GPRS standard; The whole platform will be completely designed to be compatible with UMTS.
