<p>The invention is referring to a syringe (1), comprising a container (2), a needle (3) capable of co-acting with one end (2a) of the container, a plunger (4') which is located inside the container and which co-acts sealingly with the inner surface thereof, and a rod-shaped element which coacts with the plunger and which is arranged for rectilinear reciprocating movement relative to the container. There being provided means which takes an inactive state, in which co-action between the rod-shaped element (5) and the plunger (4') is discontinued, therewith to prevent further liquid from being drawn into the container upon renewed linear movement of the rod-shaped element in a first direction (P1). The plunger or a part thereof (4') is intended to take a position in which the plunger (4') is effective to prevent the container (2) from being filled with injection liquid via the needle (3) or its attachment means.</p> |
