A u-healthcare remote diagnosis system is proposed for chronic disease and medical vulnerable groups check the health systematically and support for the most optimal environment to improve the quality of life. The u-healthcare remote diagnosis system using wireless measure the thoracic sound in the chest. And this is demonstrated that the system using radio frequency is not be affected by the electromagnetic wave with the use of an experiment and by confirming that this u-healthcare remote diagnosis system can not affect the doctors and the patients.
Korea and the world population are suffering from heart and lung disease due to aging. There are only few objective data regarding to bronchial or lung sounds. Therefore, it is necessary to normalize the data for breathing sounds objectively. In this paper, we analyze lung data using algorithm PCA (Principal Component Analysis) and AVRLCR (Average Level Crossing Rate) and then present an objective data about asthma and pneumonia. Peak frequency and AVRLCR value of spectrum show the significant differences depend on the type of diseases. And based on the period of the waveform, the waveform is displayed by autocorrelation and the pulse rate is displayed in real-time.
The modern day is witnessing rapid development of interest in health following the improvement of medical treatment technology as well as of the standard of life. Increasing demand for cutting-edge IT technology for health service is based on the desire better life. It changes the focus of health care service paradigm from treatmentoriented suppliers to consumer who requires preventive healthcare and wellness. Although widely distributed smart devices are used to provide smart health care service in order to keep pace with this paradigm change, it suffers from lack of integrated service system. The most universal touchstone to measure patient's state is body temperature, blood pressure, heart rate, oxygen saturation level, stethoscope, etc. Basic medical instruments are kept in many homes for family health. However, most personal medical equipment so far is stand-alone products which cannot keep tracks for family health issues. u-Healthcare system for smart phones uses vital-integrated communication module. This smart application for diagnosis system sends body sounds and signals (temperature, blood pressure, heart rate, oxygen saturation level, and stethoscope) to smart phone for diagnosis regardless of time and place. This study describes hardware construction of the diagnostic system in detail and argues new concept of diagnostic system environment via a smart phone application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
