Abstract
The present invention relates to a finger grip (1) arranged to be connected to a syringe barrel having a plunger and a plunger rod for driving said plunger. The finger grip comprises a body having a lower side with finger supporting surfaces (13) for supporting fingers of a user during handling and an engagement member (5) being moveable between an inactive position where the engagement member is arranged not to engage with the plunger rod of the syringe barrel and an active position where the engagement member is arranged to engage with a grooved surface on the plunger rod of the syringe such that feedback is given to a user as the plunger is moved relative to the finger grip. An activation member (7) for moving the engagement member from said inactive position to said active position is built-in into the finger grip.
