1. A fluid supply body for supplying a fluid to a balloon formed of a material having elasticity and inflating the balloon, the fluid supply body comprising:
a cylinder that is a tubular shape having a first opening and a second opening at both ends thereof, and that contains the fluid; a plunger that is inserted into the cylinder from the second opening so as to be able to advance and retract in a direction of an axis of the cylinder and that pushes out the fluid which is in the cylinder from the first opening to the outside of the cylinder; an adjusting portion that is attached to the plunger and adjusts the movement amount of the plunger so that the balloon is inflated to a predetermined inflation diameter, the inflation diameter being changed as the balloon is inflated; a fixing portion that is provided at the cylinder and fixes the plunger at a position within the cylinder corresponding to the movement amount adjusted by the adjusting portion, the fixing portion including a first finger-hooked portion, and a second finger-hooked portion that is fixed to the cylinder; a plurality of engaging portions that are provided at the adjusting portion and specify movement amounts corresponding to a plurality of different inflation diameters of the balloon; and an engaged portion that is provided at the fixing portion, and is engaged with the engaging portions, wherein
the first finger-hooked portion is disposed on a front side relative to the second finger-hooked portion in a direction in which the plunger is pushed into the cylinder, and is movable relative to the second finger-hooked portion, andthe first finger-hooked portion moves relative to the second finger-hooked portion, and thereby the engagement of the engaging portions to the engaged portion is released. |
