Abstract
A blood pressure meter includes an adjustment unit that adjusts a pressure in a cuff by controlling a piezoelectric pump that uses a piezoelectric vibrator to supply fluid to the cuff, a driving control unit that gradually changes a cuff pressure by performing driving control on the adjustment unit, a pressure detection unit that detects the cuff pressure, a blood pressure determination unit that determines a blood pressure value, a circumferential length detection unit that detects a circumferential length of the measurement area, a battery that supplies power to various units, and a decrease detection unit that detects a voltage decrease value for the battery during blood pressure measurement. Based on the circumferential length and the voltage decrease value detected in an initial inflation period when the blood pressure measurement is first started, a range of the voltage decrease value during blood pressure measurement carried out thereafter is estimated.
