According to a first aspect of the invention a syringe comprising a barrel (1), a plunger (2) moveably arranged within said barrel and a plunger rod (3) for driving said plunger is provided. The syringe comprises a first engagement member (30) arranged at the plunger rod such that a longitudinal movement of the plunger rod yields a rotational movement of said first engagement member, said first engagement member comprising a grooved surface, and a second engagement member (40) arranged at the barrel to engage with said grooved surface of the first engagement member such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving said plunger. Wherein, for a given distance D travelled by the plunger rod relative to the barrel, a point of the grooved surface of the first engagement member moves a distance d, wherein d=D.
