NON-INVASIE MICRO-OPTO-ELECTRO-MECHANICAL SYSTEM ADAPTATION TO RADIAL BLOOD FLOW PULSE AND VELOCITY ANALYSIS

Radial pulse examination is one of the most important diagnostic methods in traditional Chinese medicine. It has been used in establishing diseases and in guiding medicine selection for thousands of years. Blood flow fluctuation types present in radial artery contains rich and critical information which can reflect the state of various problems with health. Having precisely mastered the art of blood flow pulse practitioners can exactly determine what kind of health problems (i.e. problems with: gallbladder, kidneys, stomach, lungs, heart, high level of cholesterol and more) the patient has. Being non-invasive diagnostic technique this type of examination depends on the practitioner’s subjective analysis and may be unreliable and inconsistent. In this paper, we present novel computerized non-invasive micro-opto-electro-mechanical radial pulse signal analysis techniques strongly correlating with the valuable knowledge of traditional Chinese medicine. First, the fluctuations of blood flow are registered by laser triangulation displacement sensor. Then, using computer based techniques the signal is filtered from possible noise. Possible prototype model of final object is presented. Experiment results show that the proposed system works accurately and could be especially effective and helpful in ambulance medicine because of its portability and manufacturing price.
