Patent ID: 7585287

Claim:
A device for inserting a subcutaneous infusion device into skin of a patient, comprising: a housing; a needle hub including a needle; a sleeve; a cap coupled to the housing, the cap defining a bead, and the cap defining a boss extending from a closed end of the cap, the boss defining a central cavity sized to receive the needle and associated cannula of the infusion device; and a retention member including a tab extending outward radially from the sleeve and configured to engage the bead defined by the cap to limit movement of the sleeve relative to the housing while the cap is coupled to the housing so that the sleeve is prevented from moving to a trigger state; wherein a free end of the boss of the cap engages a bottom surface of the infusion device to limit movement of the infusion device relative to the needle while the cap is coupled to the housing; and wherein, upon removal of the cap, the needle hub is movable relative to the sleeve to introduce the needle of the needle hub and associated cannula of an infusion device into a subcutaneous layer of skin.
