Abstract: A blood pressure monitoring apparatus including a linear relationship storage portion storing previously stored linear relationships, a blood pressure measurement portion measuring a real arterial pressure of the person to be measured, a proper relationship generation portion applying, for the person to be measured, the real arterial pressure, real compression pressures, and real pulse wave propagation velocities, to thereby generate a proper relationship on the person to be measured among the real arterial pressures of the person to be measured, the real compression pressures, and the real pulse wave propagation velocities, and a blood pressure estimation portion applying, for the person to be measured, the real compression pressures and the real pulse wave propagation velocities obtained under the real compression pressures, to the proper relationship on the person to be measured, to thereby estimate the estimated arterial pressure.

Abstract: A weight measuring apparatus can ensure safety even if a trouble or deterioration of measurement accuracy occurs. The weight measuring apparatus (10) measures a weight of fluids and includes the followings. A first arm (110) has a first fitting (111) to fit a supply fluid container (20). A second arm (120) is connected to the first arm (110) and has a second fitting (121) to fit a filtrate container (30). A third arm (130) is connected to the second arm (120). A first measuring device (220) measures, as a first total weight, a total weight of the supply fluid container (20) and the filtrate container (30) based on a change of the second arm (120). A second measuring device (230) measures, as a second total weight, the total weight based on a change of the third arm (130). An alarm (300) alarms, when the first and second total weights have different values having a difference equal to or greater than a predetermined value.
