摘要： A syringe (2) for dispensing a fluid, the syringe including a barrel (4) including a discharge end (10) defining a discharge passage, and a plunger (15) disposed within the barrel, the plunger being adapted to move within the barrel such that the plunger and discharge end define a variable volume chamber within the barrel and the plunger is capable of displacing fluid from the chamber through the discharge passage; wherein the syringe includes a rotational element (20a, 20b, 24a, 24b) adapted to rotate about longitudinal axis of the syringe and which has a first axial orientation relative to the discharge end of the barrel and a first stop is provided on the plunger and/or the barrel which is adapted to limit axial movement of the plunger in the first orientation of the rotational element, and the rotational element has a second axial orientation relative to the discharge end of the barrel in which the first stop is disengaged and movement of the plunger is permitted to a second stop.
