Adjustable cap and lancing device and method of use
First Claim
1. 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.

Abstract
Disclosed are cap embodiments each comprising a body having a skin-engaging end defining a piercing aperture, a lancet receiver, and an intermediate member. A first cam path is located on one of the lancet receiver and the intermediate member, and a first cam follower is located on the other of the lancet receiver and the intermediate member that engages the first cam path. A second cam path is located on one of the cap body and the intermediate member, and a second cam follower is located on the other of the cap body and the intermediate member that engages the second cam path. The first and second cam paths are configured such that rotation of the intermediate member by an actuating mechanism causes the cap body to move forward and rearward and the lancet receiver to move forward and rearward. Also disclosed are lancing devices and methods of use.

1. 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method of use of a cap of a lancing device having a housing and a cap body with an inner surface and a skin-engaging end defining a piercing aperture, the method comprising:
-
a lancet receiver movably mounted in the cap body, wherein adjusting an effective size of the piercing aperture by moving the lancet receiver between a forward position and a rearward position, wherein an end of the lancet receiver is circumscribed by and is substantially co-planar with the skin-engaging end when the lancet receiver is in the forward position, with the end of the lancet receiver defining the piercing aperture, and the lancet receiver is positioned sufficiently spaced apart from the piercing aperture to permit skin to pucker through the piercing aperture during lancing when in the rearward position; and adjusting a penetration depth of a lancet by moving the cap body forward and rearward when the lancet receiver is in either of the forward and rearward positions, wherein the cap body has an intermediate member movably mounted in the cap body and having an inner surface facing an outer surface of the lancet receiver, an outer surface facing the inner surface of the cap body and an actuating mechanism attached to the intermediate member, wherein adjusting the effective size comprises rotating the intermediate member with the actuating mechanism to move a first cam follower located on one of the outer surface of the lancet receiver and the inner surface of the intermediate member along a first cam path located on the other of the outer surface of the lancet receiver and the inner surface of the intermediate member to move the lancet receiver forward and rearward with respect to the housing, and wherein adjusting the penetration depth comprises rotating the intermediate member with the actuation member to move a second cam follower located on one of the inner surface of the cap body and the outer surface of the intermediate member along a second cam path on the other of the inner surface of the cap body and the outer surface of the intermediate member such that the cap body moves forward and rearward relative to the housing at a different time than the lancet receiver. - View Dependent Claims (11, 12, 13)

14. A cap for a lancing device including a housing and a lancet firing mechanism disposed in the housing, the cap comprising:
-
a cap body with a skin-engaging end defining a piercing aperture; a lancet receiver movably disposed in the cap body; an intermediate member movably disposed between the lancet receiver and the cap body; a first cam path and a first cam follower movably connecting the lancet receiver and the intermediate member; a second cam path and a second cam follower movably connecting the cap body and the intermediate member; and an actuating mechanism accessible external to the cap body and carried by 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 a lancet by moving the cap body forward and rearward relative 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 relative to the housing. - View Dependent Claims (15, 16, 17, 18, 19, 20)
