Abstract：
 The invention is an oxygen saturation of blood in partial tissue in the brain of a newborn baby under the stimulation of absorbing oxygen, and its characteristic: it takes three photoelectric receiving tubes placed on the same straight line and a light source containing two LEDs as sensor, based on that in the tissue oxygen metabolism, oxyhemoglobin and reduced hemoglobin have different optical spectrum properties, and according to the light absorbing and scattering laws in the tissue, calculating the oxygen saturation rSO2 of blood in partial tissue, and on the condition of short-time pure oxygen absorbing, able to detect and calculate the variation of oxygen saturation of blood in partial tissue of a newborn baby. The three photoelectric receiving tubes are arranged at regular intervals, and the two LEDs can emit red and near-infrared lights, respectively. The invention can sensitively detect the oxygen saturation of blood in partial tissue of a newborn bay or bay suffering from diseases and its variation course.
