Patent ID: 8870822

Claim:
An insertion device for an insertion head with at least one of an infusion cannula or a puncturing tip for introduction into the body of a patient, the insertion device comprising: a housing; at least one contact face for placing on an application site on the body of the patient for application of the insertion head; retention means with which the insertion head that is to be applied is temporarily held on the insertion device; a drive mechanism configured to supply a drive force for effecting an insertion movement of the insertion head relative to the contact face from a first position in which the insertion head is held by the retention means such that the infusion cannula or the puncturing tip is set back relative to the contact face to a second position in which the infusion cannula or the puncturing tip protrudes beyond the contact face to permit introduction of the infusion cannula or of the puncturing tip into the body of the patient when the insertion movement is executed with the contact face of the insertion device placed on the body; a first actuation member slidably coupled to the housing, wherein the contact face forms a distal end of the first actuation member; and a second actuation member; wherein the first and second actuation members have to be actuated sequentially to trigger the insertion movement, wherein the first actuation member has at least one opening adjacent an end opposite the distal end, and the second actuation member can only be actuated while the first actuation member is actuated by the contact face being pressed against the body of the patient such that it is slid relative to the housing so as to bring the at least one opening into alignment with the second actuation member and permit the second actuation member to move radially inward through the opening to be actuated.
