Classification: CPC A | IPC A

Claim 1:
2. 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 device 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 device; and
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 force of the insertion device, relative to the cannula housing in order to carry out an insertion movement or insertion of the cannula,
wherein the safety mechanism comprises a softenable or fusible material provided on a heating element, which is heatable and softened by the heating element from a side and/or on a surface and/or weakened with respect to a mechanical carrying or holding capacity of the softenable or fusible material, or severed or at least partially or completely melted, and
wherein the safety mechanism is under a compressive stress from the triggering element and presses against the heating element.
