Implementation of Ubiquitous Health Care System for Active Measure of Emergencies

The present study discusses the construction of a ubiquitous health care system that can cope actively with urgent situations of chronic disease patients who can lead everyday life despite their chronic diseases. If a patient´s emergency is detected by personal health care host (PHCH), which is composed of USN, electronic stethoscope, GPS, CDMA and RFID, a text message containing position information is sent immediately to the hospital and the guardian´s mobile terminal so that they can take an action immediately. In particular, data from accelerometers and vibration sensors, which are composed of ubiquitous sensors, are learned using the back-propagation network algorithm, therefore emergencies such as syncope and convulsion are determined actively. The experiments show that this system is very effective to find emergencies promptly for chronic disease patients who cannot take care of themselves and it is expected to save many lives.
