Optical Detection in Valvular Heart Disease

Abstract

In this study, we develop a rapid detection system to assess the heart valve function. This system uses a sphygmomanometer combined with temperature and pulse sensing system. By this system, the initial diagnosis can be carried out quickly. This system uses Labview as development environment to design the human-machine interface. By pressurization and pressure relief on arm, the temperature of Peripheral-limb will change. Finally, basing on the test results to analyze the temperature curve, it shows that there is approximately 3°C to 4.5°C temperature difference.
