Abstract
An insertion system having a base unit for placing on the body of a patient and an insertion device that can be coupled to the base unit, wherein the insertion device comprises an insertion needle holder for holding an insertion needle and a drive mechanism for displacing the insertion needle holder in a pricking direction. According to the invention, the insertion device comprises a locking mechanism causing locking of the drive mechanism in an active state and being set to an inactive state in which the locking is released by coupling the insertion device to the base unit.

16. An insertion system comprising a base unit for placing on the body of a patient and an insertion device that can be coupled to the base unit, whereby the insertion device comprises:
-
an insertion needle holder for holding an insertion needle; a drive mechanism for moving the insertion needle holder in a puncturing direction; and a locking mechanism that effects locking of the drive mechanism in an active state and is transitioned to an inactive state, in which the locking is released, by coupling the insertion device to the base unit;
wherein the locking mechanism comprises a slider that is displaced from the active state to the inactive state upon a switch of the locking mechanism, the slider being coupled to a latching element that is slid into an engagement position when the insertion device is coupled to the base unit, in which engagement position it connects the insertion device to the base unit in a positive fit-type manner.
