摘要： The embodiment provides a blood pressure measurement device equipped with a pressing surface having plural pressure sensors arranged in one direction, an air bag for pressing the pressing surface against a living body part in a state that the one direction crosses a direction in which the radius artery T runs, an air bag drive unit, a rotational drive unit for driving the pressing surface rotationally about at least one of axes X and Y, and a control unit which performs a rotation control on the basis of pressure pulse waves that were detected by the pressure sensors in a process that the pressing force was increased and calculates blood pressure values on the basis of pressure pulse waves that were detected by the pressure sensors after the rotation control in a process that the pressing force was decreased.

摘要： The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

摘要： A blood pressure measuring cuff according to the present invention includes a pressing cuff which is belt-shaped, is wrapped around a part to be measured, and receives supply of a pressurizing fluid to press the part to be measured. An arterial pressure sensor for detecting pressure applied to an artery passing portion of the part to be measured by the pressing cuff is disposed at a portion of an inner peripheral surface of the pressing cuff which should face an artery of the part to be measured, separately from the pressing cuff.

摘要： A toothbrush of the present invention includes: a main body including a head portion having a bristle raising surface on which bristles are provided in a standing manner; a light emission unit configured to emit light through a specific region of the bristle raising surface to a tooth surface; and a light reception unit configured to receive radiated light from the tooth surface resulting from the light through the specific region, the light emission unit and the light reception unit being provided in the main body. The toothbrush also includes a detection unit configured to collectively detect whether or not dental plaque or dental calculus is present on the tooth surface based on an output from the light reception unit. The toothbrush further includes a determination unit configured to determine that dental calculus is present on the tooth surface.
