A cuff-pressure control device includes a pump supplying gas into the cuff, a connection path connecting the pump and the cuff, an exhaust valve exhausting gas in the cuff through the connection path, a pressure sensor measuring an internal pressure of the connection path, and a controller controlling the internal pressure of the cuff according to a measured value of the internal pressure of the connection path measured with the pressure sensor. The controller includes an obstruction detection unit that obtains, from the measured value of the pressure sensor, a pressure change amount from a time point when the pump is stopped while the internal pressure of the connection path is being increased by the pump to a time point after a predetermined time elapses and that detects the obstruction of the connection tube when the pressure change amount is less than or equal to a predetermined threshold value.

A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate including a first main surface and a second main surface, and a frame plate surrounding the surroundings of the vibrating plate. The driver is provided on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate has a hole formed thereon. Furthermore, the flexible plate faces the second main surface of the vibrating plate, and adheres to the frame plate by the adhesive agent that contains a plurality of particles arranged such that the plurality of particles are interposed between the flexible plate and the vibrating plate.
