<p>A prefilled syringe is configured so that, in order that a liquid medicine injected and administered into the upper layer of skin is prevented from leaking out of the living organism, a pressing section can be held at a position at which the pressing section has been completely pressed in. A prefilled syringe (1) is provided with: a double-headed needle (3) having a needlepoint (9) which can be inserted into a living organism; a needle hub (4) for holding the double-headed needle (3); an outer tube (2); a pressing section (22); a liquid medicine storage section (6) for storing a liquid medicine (M); a holding section (8); and a sealing body (23). The liquid medicine storage section (6) is disposed within a tube hole (2a) of the outer tube (2). The pressing section (22) operates the liquid medicine storage section (6) so that the liquid medicine storage section (6) can move in the direction of the axis of the tube hole (2a) of the outer tube (2). In a pressed state in which the liquid medicine storage section (6) and the pressing section (22) have been moved to the needle hub (4) side until the liquid medicine (M) stored within the liquid medicine storage section (6) has been discharged, the holding section (8) holds the pressed state of the pressing section (22).</p> |
