To enable correction of measured pressure without stopping pumping operation.SOLUTION: A pressure P1 measured by a first pressure sensor 30 disposed on a balloon 28 is stored, and when driving the balloon, the measured pressure P1 is calibrated by a pressure P2 measured by a second pressure sensor 32 that measures the pressure inside a semi-inflated balloon at predetermined intervals. A pressure P3 obtained from a third sensor 34, different from the first and second pressure sensors, is used, and when the pressure P1 is smaller than the pressures P3 by more than a predetermined value, a difference OF2 between P3 and P1 is used to correct the stored P1, to display the difference OF2 to enable manual adjustment, or to store the difference OF2.SELECTED DRAWING: Figure 1 【課題】ポンピング動作を停止することなく、測定圧力の修正を可能とする。【解決手段】バルーン２８に配された第１圧力センサ３０による測定圧力Ｐ１を記憶し、バルーンを駆動するにあたり、所定時間毎に半膨張バルーン内の圧力を測定する第２圧力センサ３２による測定圧力Ｐ２によりＰ１を校正するとともに、第１と第２の圧力センサとは別個の第３圧力センサ３４から得られる圧力Ｐ３を用い、圧力Ｐ１が圧力Ｐ３より所定値を超えて小さいとき、Ｐ３とＰ１の差分ＯＦ２を用いて、記憶されていたＰ１を修正するか、差分ＯＦ２を表示して手動での調整を可能とするか、あるいは差分ＯＦ２を記憶する。【選択図】図１
