A display unit arranged on the surface side and capable of displaying the driving state of the balloon catheter; and a control unit which is housed inside and controls the pressure generating means and the display unit, and is detachable from the monitor installation unit And a monitor unit capable of communicating with the apparatus main body,
The monitor installation part includes a base part extending in a vertical direction from the main body casing part, a movable part provided at an upper end of the base part and movable in a predetermined direction, and a monitor insertion part connected to the movable part. And
The monitor unit includes a socket unit that is disposed on a back surface of the monitor unit and into which at least a part of the monitor insertion unit is inserted.

  The monitor unit serving as the display device of the IABP driving device according to the present invention is detachably attached to the apparatus main body by inserting the monitor insertion unit in the monitor installation unit into the socket unit disposed on the back surface of the monitor unit. It is done. Thereby, the IABP drive device according to the present invention quickly switches the use state between the use state in which the monitor unit is attached to the apparatus main body and the use state in which the monitor unit is installed in a place away from the apparatus main body. Can do. Further, since the control unit is provided in the monitor unit, arithmetic processing using the signal from the apparatus main body, display, pressure generation means control, and the like can be performed centrally on the monitor unit.

Further, for example, a split tip portion that is divided into a first portion and a second portion by cutting along the insertion direction of the monitor insert portion may be formed near the tip of the monitor insert portion,
The socket portion has a support column that is connected between the first portion and the second portion in a state where the two insertion surfaces of the socket portion are connected and the monitor insertion portion is inserted into the socket portion. You may do it.

  The monitor unit having the control unit tends to be slightly heavy, and a relatively large load may be applied to the socket unit when the operation of changing the orientation of the monitor unit by holding a part of the monitor unit is performed. The socket part is preferably made to be sturdy. A split tip is formed in the monitor insertion part, and the socket part has a support column connecting the opposing surfaces, so that the strength of the socket part is improved.
