Beschreibung
Zusammenfassung:	The present invention relates to a syringe (100) comprising a barrel (1), a plunger (2) moveably arranged within the barrel (1) and a plunger rod (3) for driving the plunger (2), and an engagement member (4) arranged at the barrel (1) to engage with a grooved surface (5) on the plunger rod (3). This will create feedback given to a user as the plunger rod (3) is moved relative to the barrel (1) for driving the plunger (2) within the barrel (1). The barrel (1) and the engagement member (4) are arranged relative to each other such that the engagement member (4), due to the engagement with the grooved surface (5) of the plunger rod (3), will move solely in a direction generally perpendicular to a longitudinal direction of the plunger rod (3) as the plunger rod (3) is moved relative to the barrel (1).
