(57) [Problem] To provide a method and a sphygmomanometer that can continuously measure blood pressure, can be downsized, and can safely and easily measure blood pressure anywhere. Is to do. A blood pressure measurement method according to the present invention is characterized in that a side pressure of a blood flow and a dynamic pressure of a blood flow in the same blood vessel are simultaneously measured, and the following formula is calculated. (Blood pressure) = (side pressure of blood flow) + (dynamic pressure of blood flow) Here, as for the dynamic pressure of blood flow, (dynamic pressure of blood flow) = 1 / 2 × may obtained from (blood density) × (flow rate of the blood flow) 2. Further, the sphygmomanometer of the present invention is characterized in that it comprises means for measuring the lateral pressure of the blood flow, means for measuring the flow velocity of the blood flow, and a central processing unit for calculating the following equation. (Blood pressure) = (side pressure of blood flow) + 1/2 × (blood density) × (Blood flow velocity) 2 |
