Abstract
A needleless syringe that may administer a fixed amount of liquid in multiple doses in a continuous manner including a plunger and a piston for pushing out the liquid from a liquid container are provided in a cylinder. Gas introduced in a gas supply part may flow into an airtight space by the opening operation of a valve mechanism linked to the pushing of an upper second operating lever, and a piston may move and push a pressing member. When the liquid injection based on a certain stroke is completed, the gas in the airtight space may be released outside a casing by a gas release mechanism. The piston and the pressing member may move back, and the pressing member, which has multiple pressing surfaces with different axial positions, may be rotated by a pressing surface change mechanism to change the pressing surface.
