Abstract

A syringe (1) comprises a hollow cylindrical barrel (2), a plunger (9) which delimits a chamber within the barrel (2) and which is longitudinally reciprocable within the barrel (2) to draw liquid into, and expel liquid from, the chamber by way of an outlet (3), and a deactivating arrangement which, after the plunger (9) has been moved to a position to expel the liquid from the chamber, prevents further liquid from being drawn into the chamber. Such an arrangement renders the syringe (1) non-reusable.
