PROBLEM TO BE SOLVED: To provide a tissue oxygen saturation measuring device capable of continuously measuring the hemoglobin concentration and the blood oxygen saturation of a biological tissue by separating the blood and tissues other than the blood in the biological tissue. SOLUTION: The tissue oxygen saturation measuring device 100 calculates an absorption coefficient of the biological tissue 200 from the spacial difference of absorption between different light receiving windows 3A and 3B, and finds the quantity of oxygenation hemoglobin per unit tissue and the quantity of deoxygenation hemoglobin from the difference between the absorption coefficient excluding the blood in the biological tissue 200 by pressing the periphery of a wearing region including the transmitting/receiving light sensor wearing region and the absorption coefficient including the blood after the release of the pressure. In this way, the biological tissue 200 excluding the blood and the blood included in the biological tissue 200 are separated to measure the blood oxygen saturation. COPYRIGHT: (C)2006,JPO&NCIPI
