Abstract
A syringe including a barrel, a plunger moveably arranged within the barrel and a plunger rod for driving the plunger, and an engagement member arranged at the barrel to engage with a grooved surface on the plunger rod. This will create feedback given to a user as the plunger rod is moved relative to the barrel for driving the plunger within the barrel. The barrel and the engagement member are arranged relative to each other such that the engagement member, due to the engagement with the grooved surface of the plunger rod, will move solely in a direction generally perpendicular to a longitudinal direction of the plunger rod as the plunger rod is moved relative to the barrel.
