Ubiquitous Healthcare System for Analysis of Chronic Patients' Biological and Lifelog Data

For the prevention and management of diseases in chronic patients, attention has been directed at ubiquitous healthcare systems in order to reduce medical expenses and provide high-quality medical services at different places, including hospitals and homes. In this paper, a ubiquitous healthcare system has been proposed in order to care for a chronic patient, to be used by a nurse or a care professional at the patient's residence. It comprises a portable bio-signal acquisition device, smartphone application, and ubiquitous health server. The smartphone application collects the patient information, including lifelog and the bio-signals from the device, and transfers the patient information through bio-signals to the ubiquitous health server. The ubiquitous health server monitors the bio-signals with the help of lifelog, analyzes the patient's health state, and alerts medical staff on symptoms of any illness. The proposed system collects five types of bio-signals from patients using the acquisition device, automatically monitors and analyzes their bio-data with lifelog, displays the state of their health as determined by the analysis, using graphical representation, such that the doctor can understand the patient's condition and undertake an appropriate medical treatment procedure.
