摘要： A blood pressure information measurement device includes light emitting elements and light receiving elements as a plurality of pairs of first and second sensors in a cuff. While the cuff pressure is increased, combinations of the plurality of pairs of the light emitting elements and the light receiving elements are switched, and volume pulse waves are obtained from each of the combinations. After increasing the cuff pressure, for each of the volume pulse waves corresponding to the combinations, a specific volume value at a point where the amount of volume change becomes maximal is extracted. Thereafter, based on values corresponding to the maximum and minimum blood pressure and the specific volume value, the sensors for measurement are determined.

摘要： An electronic manometer detects pressure within a cuff at which an amplitude of change in a volume of an artery of a measurement subject becomes a maximum by detecting volume of an artery of a measurement subject while superimposing a vibration of high frequency during a period of raising the pressure to apply on the cuff or during a period of lowering after raising to greater than or equal to a systolic blood pressure of the measurement subject. The electronic manometer controls the pressure to apply on the cuff so that the volume of the artery of the measurement subject becomes constant, and measures the blood pressure of the measurement subject from an increased or decreased value of the pressure to apply.

摘要： A small and inexpensive, noninvasive bone density measuring device is provided. A measuring part of the bone density measuring device is constituted by a light emitter 120, which emits near-infrared light, and a light receiver 130, which receives light via a bone of a measuring subject, arranged in a holder 110. Bone density is measured by inserting an arm, for example, in the holder 110 and measuring light absorption (absorbance) by the arm bone. The light emitter 120 and the light receiver 130 are connected to a control unit 140. The control unit 140 controls the light emitter 120 to emit light, inputs a measured value from the light receiver 130, and displays it as bone density. In order to remove the influence of light from the background or difference in bone thickness, ratio of absorbance between two wavelengths is preferably employed. In order to obtain light of twowavelengths, use ofasingle light receiving element is possible by making two light emitting elements (LEDs) alternately emit light even in the case of using two light emitting elements.
