• a needle shield remover coupled to the needle shield portion, wherein the needle shield remover comprises:
• an elongated member having a grasping portion on a distal end thereof, the elongated member configured to extend along the bottom portion of the housing in a first position and extend away from the bottom portion of the housing in a second position;
• and
• a grasping portion on a distal end of the elongated member;
• wherein a bottom surface portion of the elongated member is coupled to the removable liner proximate to a front edge location of the adhesive pad element;
• pivoting the elongated member from the first position towards the second position such that the removable liner is peeled away from the primary adhesive layer at the front edge location of the adhesive pad element, with the removable liner being peeled away from the primary adhesive layer in a single direction from the front edge location of the adhesive pad toward an opposing back edge location of the adhesive pad;
