<P>PROBLEM TO BE SOLVED: To enhance accuracy of interpolation to a pulse wave amplitude to provide proper measuring results of the maximum blood pressure/the minimum blood pressure to a user and to reduce the fluctuation of the measured values, thereby eliminating a sense of anxiety of the user, in an electronic sphygmomanometer. <P>SOLUTION: With the maximum blood pressure-determining pulse wave amplitude or the minimum blood pressure-determining pulse wave amplitude as a boundary in the relation of the measured cuff pressures and pulse wave amplitudes, one or a plurality of measured values are selected as the first measured value group from the measured value of one side, and a plurality of measured values are selected as the second measured value group from the measured values of the other side. Three or more of combinations of straight lines connecting any one of the first measured value group and any one of the second measured value group are calculated as a plurality of interpolation primary expressions, a plurality of cuff pressures in the intersecting point between the plurality of the interpolation primary expression and the maximum blood pressure-determining pulse wave amplitude or the minimum blood pressure-determining pulse wave amplitude are calculated, and the plurality of cuff pressures are averaged, thereby determining the maximum blood pressure or the minimum blood pressure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
