<p>PCT No. PCT/SE88/00634 Sec. 371 Date May 16, 1990 Sec. 102(e) Date May 16, 1990 PCT Filed Nov. 22, 1988 PCT Pub. No. WO89/04677 PCT Pub. Date Jun. 1, 1989.The invention relates to a syringe (1) comprising a container (2), a needle (3) capable of co-acting with one end of the container, a plunger (4) which is arranged in the container and which sealingly co-acts with the inner surface (2c) thereof, and a rod-shaped element (5) which co-acts with the plunger (4) and which is arranged for reciprocating movement relative to the container (2), such that movement of the element from the one end (2a) in a first direction (P1) enables the container (2) to be filled with injection liquid, while linear movement in the opposite direction (P2) causes liquid in the container to be discharged therefrom through the needle (3). Provided between the plunger (4) and the element (5), for their mutual co-action, is a crewsthreaded means (6) which holds the plunger (4) firmly to the rod-shaped element (5) when the element moves in the first direction (P1) but which adopts an inactive state when the element (5) is moved in the opposite direction, therewith rendering refilling of the container impossible.</p> |
