Patent ID: 8092476

Claim:
A cap for use with a lancing device having a housing and a lancet firing mechanism disposed therein, the cap comprising: a cap body having an inner surface and a skin-engaging end that defines a piercing aperture; a lancet receiver movably mounted in the cap body and having an outer surface, the lancet receiver configured to receive a lancet; an intermediate member movably mounted in the cap body and having an inner surface facing the outer surface of the lancet receiver; a first cam path on one of the outer surface of the lancet receiver and the inner surface of the intermediate member; a first cam follower on the other of the outer surface of the lancet receiver and the inner surface of the intermediate member that engages the first cam path; a second cam path on one of the inner surface of the cap body and an outer surface of the intermediate member; a second cam follower on the other of the inner surface of the cap body and the outer surface of the intermediate member that engages the second cam path; and an actuating mechanism attached to the intermediate member, wherein rotation of the intermediate member by the actuating mechanism causes the second cam follower to move along the second cam path to adjust a penetration depth of the lancet by moving the cap body forward and rearward with respect to the housing and causes the first cam follower to move along the first cam path to adjust an effective size of the piercing aperture by moving the lancet receiver forward and rearward with respect to the housing.
