摘要： A light beam having a first wavelength (.lambda..sub.1) is applied to the blood from a first light radiation section, while a light beam having a second wavelength (.lambda..sub.2) is applied from second and third light radiation sections different in positions from the first radiation section and from each other to the blood and the respective reflected-light intensity (I.sub.1, I.sub.2, I.sub.3) is detected. A first correction value (X) for correcting the reflected-light intensity ratio (I.sub.2 /I.sub.3) is calculated by a first correction value operation section (40) and a second correction value (C.sub.1) is calculated by a second correction value operation section (42) by use of this first correction value and the reflected-light intensity (I.sub.3). The reflected-light intensity ratio (I.sub.1 /I.sub.2) is corrected by use of this second correction value and an oxygen saturation in the blood is operated based on correlation function by use of the corrected reflected-light intensity ratio (R.sub.s). The reflected-light intensity ratio (I.sub.2 /I.sub.3) is corrected by the coefficient of correction thus operated and the hemoglobin concentration in the blood is operated based on correlation function by use of the reflected light intensity ratio thus corrected.

摘要： An optical sensor probe for emitting light into blood and detecting light reflected by the blood, having one end of a first light transmitting member brought into contact with blood flowing through a conduit, and capable of emitting light into the blood in the conduit by introducing the light into the first light transmitting member from the other end thereof. Part of the light emitted into the blood by the first light transmitting member and reflected by the blood is introduced into the second light transmitting member from one end of the same in contact with the blood and is transmitted to a light detecting device. The end of the second light transmitting member is disposed in a side wall of the conduit at a predetermined distance from the end of the first light transmitting member in contact with the blood.

摘要： Light components are radiated into a blood vessel from light-emitting diodes (17, 18) for emitting light components having different wavelengths through an optical fiber. Bight components reflected by the blood upon radiation into the blood vessel are received by a photo transistor (19) to detect their reflected light intensities. For example, a minimum value of the reflected light intensity of the light component from the light-emitting diode (18) is obtained from the reflected light intensities detected within a predetermined period of time. A measurement value is calculated using this minimum value and a minimum value of the reflected light intensity of the light component from the corresponding light-emitting diode (17).

摘要： A flow-velocity sensor probe includes a thermistor for generating heat which is placed in a fluid, and a waterproof resin and a metal piece for easily radiating the heat generated by the thermistor. The flow velocity of the fluid is measured continuously from a change of temperature in the thermistor, and the thermistor is provided in close proximity to the metal piece for transmitting the heat to the fluid.
