1. 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.

Abstract
An insertion device for applying an infusion set to the body of a patient, wherein the device has two actuation members which have to be actuated simultaneously to trigger an insertion movement by which a cannula of the infusion set is introduced into the body and wherein, in some embodiments, one of the actuation members is a securing slide including a contact face to be placed on the body of the patient, the securing slide being actuated by the insertion device being pressed, via the contact face, against the body of the patient.

12. An arrangement comprising an insertion device and an insertion head receiveable in said insertion device, the insertion device comprising:
-
a) at least one contact face for placing the insertion device on an application site on the body of the patient for application of the insertion head; b) a retainer with which the insertion head that is to be applied is temporarily held on the insertion device; c) a drive for automatically 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 retainer such that an infusion cannula or a 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; and d) at least two actuation members which have to be actuated sequentially to trigger the insertion movement, wherein a first of the actuation members is actuated by the contact face being pressed onto the body of the patient and a second of the actuation members is actuated by a movement that is independent of said pressing onto the body of the patient, and wherein the first of the actuation members has at least one opening adjacent an end opposite the contact face, and the second of the actuation members can only be actuated while the first of the actuation members is actuated by the contact face being pressed against the body of the patient so as to bring the at least one opening into alignment with the second of the actuation members and permit the second of the actuation members to move radially inward through the opening to be actuated. - View Dependent Claims (13, 14)
