Abstract
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.
