Claim 14:
15. An insertion mechanism for a cannula, comprising:
a cannula housing, relative to which the cannula is displaceable;
at least one cannula holder to which the cannula is fastenable and which is movable relative to the cannula housing;
an insertion spring for generating an insertion force onto the at least one cannula holder;
a triggering element that can retain the at least one cannula holder relative to the cannula housing against the force generated by the insertion spring;
a safety mechanism which holds the triggering element in a blocking position in a safety state and releases the triggering element in a triggered state such that the triggering element is movable into a release position and the at least one cannula holder can move, driven by the insertion spring, relative to the cannula housing in order to carry out an insertion movement or insertion of the cannula, wherein the safety mechanism is under a compressive stress from the triggering element and presses against a supporting element; and
a warming or heating element that is arranged on or at the safety mechanism as the supporting element, wherein the triggering element is releasable by heating the safety mechanism.
