Abstract:
1. A blood pressure measurement device comprising: a cuff to be wrapped around a measurement site; a pressure control unit that controls a cuff pressure in the cuff when the cuff is wrapped around the measurement site; a pressure detection unit that detects the cuff pressure; a volume detection unit that detects a volume of the cuff in a process of pressurizing or depressurizing the cuff pressure by the pressure control unit; a blood pressure calculation unit that calculates a blood pressure value in the process of pressurizing or depressurizing the cuff pressure by the pressure control unit; and a wrapping strength detecting portion that detects a wrapping strength of the cuff with respect to the measurement site, wherein the wrapping strength detecting portion detects, during a change of the cuff pressure in a process of controlling the cuff pressure by pressurization or depressurization by the pressure control unit, the wrapping strength of the cuff based on a pressure-volume change relationship according to a change of the cuff pressure detected in the cuff when the cuff is wrapped around the measurement site and a volume change of the cuff detected by the volume detection unit.
