<p><P>PROBLEM TO BE SOLVED: To provide a diagnosis method and apparatus for measuring blood hemoglobin concentration, oxygen saturation, pulse rate, respiration rate and degree of aging of blood vessels using light. <P>SOLUTION: This diagnosis apparatus using light includes a control unit which receives a diagnosis instruction from a user and generates a diagnosis control signal, a measuring light generating unit for generating at least two incident light beams according to the diagnosis control signal, a light receiving unit for converting the incident light beams transmitted through an object into electrical signals, and a data processing unit which receives the electrical signals and generates designated diagnosis result information. Accordingly, blood hemoglobin concentration, oxygen saturation, respiration rate, pulse rate and age estimation of blood vessels can be non-invasively simultaneously measured without sampling blood. <P>COPYRIGHT: (C)2003,JPO</p> |
