The present invention provides a sphygmomanometer that can create, before measuring a blood pressure, a state for making a blood pressure measurement accurate. A sphygmomanometer includes a fluid circuit and a control unit. The control unit has a first preparation processing unit, a second preparation processing unit, and a measurement processing unit which operate in a worn state of the sphygmomanometer. The first preparation processing unit operates a pressing cuff to discharge remaining fluid in a sensing cuff to the atmosphere through the fluid circuit. Then, the second preparation processing unit causes the sensing cuff to store a predetermined amount of pressure transmitting fluid received from a pump through the fluid circuit. Subsequently, the measurement processing unit operates the pressing cuff and calculates the blood pressure by the oscillometric method based on pressure of the pressure transmitting fluid stored in the sensing cuff.

Sphygmomanometer, blood pressure measurement method, and computer-readable recording medium

Provided is a blood pressure measurement device capable of discharging a fluid from three cuffs even when either one of a pump valve or an on-off valve fails, that includes a pump including a pump valve; a first flow path including a first on-off valve and fluidly connecting the pump and a sensing cuff; a second flow path branching from the first flow path between the pump and the first on-off valve, including a second on-off valve, a third on-off valve, and a fourth on-off valve, and connecting the pump and atmosphere; a third flow path branching from an intermediate portion between the second on-off valve and the third on-off valve and fluidly connecting the pump and the tensile cuff; and a fourth flow path branching from an intermediate portion between the third on-off valve and the fourth on-off valve and fluidly connecting the pump and the pressing cuff.
