To provide a medical expansion/contraction driving device that can always perform pressure monitoring for balloon inner pressure adjustment without depending on a heart rate, and has a sufficient pressure monitoring function.SOLUTION: A medical expansion/contraction driving device includes: a pressure transmission diaphragm device 10 for moving and operating the gas in a gas pressure chamber 11 coming in communication with a balloon 1 in the balloon expansion direction and contraction direction; a pumping driving mechanism 13 for changing the drive pressure to be applied to the pressure transmission diaphragm device 10 according to an input signal, and switching the movement operation direction of the gas; a gas flow adjuster 59 for adjusting a flow of the gas in the movement operation by the gas of an auxiliary tank 41 side; and an adjustment operation input unit 71 for inputting an operation signal for adjusting and operating the internal pressure of the balloon 1. The medical expansion/contraction driving device is provided with a pressure sensor 55 for measuring the internal pressure of the auxiliary tank 41, and a display output unit 65 for displaying the internal pressure of the auxiliary tank 41 measured during a pressure regulation period as the monitoring pressure P2 for adjusting the balloon inner pressure.SELECTED DRAWING: Figure 1 【課題】心拍数に依存することなく、バルーン内圧調整のための圧力監視を常時実行できる、圧力監視機能の十分な医療用膨張・収縮駆動装置を提供する。【解決手段】バルーン１内に連通するガス圧力室１１内のガスをバルーン膨張方向および収縮方向に移動操作する圧力伝達隔壁装置１０と、圧力伝達隔壁装置１０に印加する駆動圧を入力信号に応じて変化させ、ガスの移動操作方向を切り替えるポンピング駆動機構１３と、移動操作中のガスの流れを補助タンク４１側のガスにより調節するガス流調節部５９と、バルーン１の内圧を調整操作するための操作信号を入力する調整操作入力部７１とを備えた医療用膨張・収縮駆動装置であり、補助タンク４１の内圧を測定する圧力センサ５５と、調圧期間中に測定される補助タンク４１の内圧をバルーン内圧調整のための監視圧力Ｐ２として表示する表示出力部６５とを設けている。【選択図】図１
