1. A blood pressure information measurement device comprising:

  • a first cuff comprising a first air bladder that attaches to an upper arm;

    a second cuff comprising a second air bladder that attaches to a lower limb;

    a measurement unit that measures a change in inner pressure of the first air bladder and a change in inner pressure of the second air bladder in synchronization;

    a detection unit that detects first blood pressure information from the change in inner pressure of the first air bladder, and detects second blood pressure information from the change in inner pressure of the second air bladder; and

    a calculation unit that performs a calculation process based on the first blood pressure information and the second blood pressure information,wherein the calculation unit executes a first calculation process of calculating a first pulse wave propagation velocity from a pulse wave or the first blood pressure information detected from the change in inner pressure of the first air bladder with the first air bladder attached to the upper arm and with blood on a peripheral side of the first cuff stopped and a pulse wave or the second blood pressure information, andwherein the calculation unit executes a determination process of determining an appropriateness of the first pulse wave propagation velocity calculated by the first calculation process using at least one blood pressure information of the first blood pressure information or the second blood pressure information.
