1. A blood pressure measurement device comprising:

  • a sphygmomanometer that measures a blood pressure of a subject;

    a sensor that detects physiological information on a type excluding the blood pressure of the subject; and

    a processor that determines a start of blood pressure measurement in the sphygmomanometer that counts a predetermined time, based on an end of a blood pressure measurement, that limits the start of the blood pressure measurement based on the physiological information, and that outputs a control signal for activating the sphygmomanometer,wherein the processor determines a first condition, determines to start the blood pressure measurement when a value obtained from the physiological information satisfies the first condition during a period outside the predetermined time, and determines to start counting the predetermined time from the end of the blood pressure measurement,wherein the processor determines not to start the blood pressure measurement during the predetermined time, if the value obtained from the physiological information satisfies the first condition,wherein the processor determines a second condition, determines to start the blood pressure measurement when the value obtained from the physiological information satisfies the second condition during the predetermined time,wherein the second condition is more critically severe than the first condition, and the physiological information of the second condition is of a same type as that of the first condition, andwherein the processor determines not to start the blood pressure measurement during the predetermined time unless the second condition that is more critically severe than the first condition is satisfied.
