1. A sphygmomanometer comprising:
a main body mounted with a pump;
a belt that extends respectively from opposite sides of the main body and is to be attached around a measurement target site;
a cuff structure having a band shape, a first end of the cuff structure being attached to the main body, the cuff structure including:
a bag-shaped pressure cuff that extends along a circumferential direction of the measurement target site so as to receive a supply of pressurization fluid to press the measurement target site,
a sensing cuff that is configured in a bag shape so as to be configured to contain pressure transmission fluid, is disposed along an inner circumferential surface of the pressure cuff, and extends in the circumferential direction across an artery passing portion of the measurement target site, and
a back plate that is inserted between the pressure cuff and the sensing cuff, extends along the circumferential direction of the measurement target site, and transmits a pressing force from the pressure cuff to the sensing cuff, wherein
in a state that the sphygmomanometer has been assembled, the cuff structure is disposed facing an inner circumferential surface of the belt and is affixed only to the main body only at the first end in a separable manner from the inner circumferential surface of the belt; and
a programmed processor that acts as:
a pressurization control unit to perform control of supplying the pressurization fluid from the pump to the pressure cuff to press the measurement target site, and
a blood pressure calculation unit to calculate a blood pressure based on a pressure of the pressure transmission fluid contained in the sensing cuff,
wherein the belt extending respectively from the opposite sides of the main body is configured to surround and restrain, in the circumferential direction, an outer circumferential side of the cuff structure extending along the circumferential direction of the measurement target site collectively with the measurement target site, in an attached state where the belt and the cuff structure together with the main body are attached to the measurement target site, such that the pressure cuff of the cuff structure presses the measurement target site.
