The present invention refers to a medication delivery device (1) comprising: a medication receptacle (6); a dosing mechanism comprising: a piston rod (17); a drive device (19); a dose setting member (27); and a dose limiting member (28) which prevents the setting of a dose of medication which exceeds an amount of medication contained in the medication receptacle (6); and a housing (3). The dose limiting member (28) is designed for axial movement in a proximal direction with respect to the piston rod (17) during dose setting and comprises a first stop element (35) and the piston rod (17) comprises a second stop element (36). The first and second stop elements (35, 35) stop an axial movement of the dose limiting member (28) in the proximal direction with respect to the piston rod (17) when the first and second stop elements (35, 36) catch, thereby limiting a movement of the dose setting member (27) for increasing a set dose of medication to be delivered. The dose limiting member (28) and the piston rod (17) only interact directly, when the first and second stop elements (35, 36) catch.

A syringe configured with a limited maximum usable capacity. The syringe of the invention desirably has a retractable needle to prevent reuse. In the preferred embodiment, a dose-limiting structure includes a stop-ring member on the head of the plunger that abuts a constriction in the housing when the plunger is moved away from the needle to prevent the further rearward movement of the plunger. Preferably, the syringe of the invention is configured such that a user is tactilely signaled when the plunger has reached a position corresponding to a nominal fixed-dose. If the user attempts to force the stop-ring member beyond the constriction, the plunger seal is stripped off or removed from the plunger head and the syringe rendered inoperable. The features of the invention can also be applied to a nonretracting syringe.
