摘要： PROBLEM TO BE SOLVED: To provide the diagnostic method of a sleep apnea syndrome capable of diagnosing the sleep apnea syndrome even at home without burdening a patient much. SOLUTION: A data processor extracts and digitizes the feature of pulse wave data detected in a pulse wave sensor and diagnoses the sleep apnea syndrome on the basis of the numerical value. For instance, at the time of paying attention to the envelope of pulse waves, since the amplitude of the fluctuation of the envelope is larger at the time of closed type apnea compared to the time of normal respiration, the closed type apnea is judged when the amplitude of the fluctuation of the envelope becomes the double or more of the value at the time of the normal respiration. Also, at the time of central type apnea, since respiration signals disappear from the envelope by the stoppage of the movement of the chest, the fluctuation of the long cycle of about 10 seconds (about 7 to 12 seconds) appears in the envelope. Thus, for instance, when the fluctuation appears in the envelopes A and B in the cycle of 7 seconds or more, the central type apnea is judged.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of the measurement precision due to adhesion of particles to a prism and glass surface of an optical sensor in an apparatus for measuring the concentration of particles of insoluble components in a lubricating oil. SOLUTION: A lubricating oil of which the concentration of insoluble component particles is to be measured is introduced into a measurement chamber 14 from an oil line of an internal combustion engine through a flow route 2. A sensor 15 is installed in the measurement chamber 14 and the concentration of particles of insoluble components is measured by utilizing light absorption, reflection, transmitting or the like. Since ions produced by ionization by an additive in the lubricating oil adhere to the particles and the particles bear electric charge, the particles are vibrated and prevented from adhering to glass face of the sensor by applying AC voltage or current to the lubricating oil from an AC power source 4.

摘要： PROBLEM TO BE SOLVED: To provide a pulse wave sensor 1 which can detect a pulse wave stably with a high probability of detection.
SOLUTION: The pulse wave sensor 1 includes a detection section 2 and a main body of the sensor 3 which are respectively fixed to the back side of a wrist by exclusive belts 10 and 14. Thereby, a shift of the position of the detection section can be made small and an influence of a body movement can be made small so that an excellent S/N ratio can be secured. Also, a surface side to touch the skin of a human body of a translucent plate 8 of the detection section 2 is comprised of a convex surface. Thereby, a degree of adhesion of the translucent plate 8 to the skin surface is improved and reflected light from the skin surface or noise light such as disturbance light or the like can be prevented from intruding so that the pulse wave sensor with the high probability of detection can be realized. Moreover, a cushioning material 15 of a sponge or a gel type is inserted between the main body 3 of the sensor which is superposed on the top of the detection section 2 and the detection section 2. Thereby, the force applied to the main body 3 of the sensor or the movement of the main body 3 of the sensor is not easily transmitted to the detection section 2.

摘要： PROBLEM TO BE SOLVED: To provide a pulse wave measurement instrument of detecting whether or not noise components are superimposed on measured pulse wave data. SOLUTION: A data processor can perform noise detection for detecting whether or not the noise components are superimposed on pulse wave information detected with a pulse wave sensor by a built-in microcomputer. To put it concretely, pulse waves are measured for fixed time, velocity pulse waves are obtained by differentiating the pulse waves and the peak value of the amplitude of the velocity pulse waves to the pulses for each beat is calculated. Then, the calculated respective peak values are standardized and the dispersion of the standardized peak values is statistically processed and digitized. Then, whether or not the digitized dispersion of the peak values is smaller than a stipulated value is judged. It is judged that the noise components are not superimposed on the pulse wave information detected in the pulse wave sensor in the case of being smaller and it is judged that the noise components are superimposed on the pulse wave information detected in the pulse wave sensor in the case of being larger.
