    摘要: The present specification relates to a syringe comprising a barrel, a plunger moveably arranged within the barrel and a plunger rod for driving the plunger, and a mechanism for providing feedback to a user as the plunger rod is moved relative to the barrel for driving said plunger such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving the plunger. The plunger rod is arranged to drive the plunger such that a predetermined relative movement between at least a portion of the plunger rod and the plunger is allowed. The present specification further relates to a plunger assembly wherein a predetermined relative movement between at least a portion of the plunger rod and the plunger is allowed.
