Cap for a lancing device
First Claim
1. A cap for a lancing device for lancing dermal tissue, the lancing device including a housing having a proximal end and a distal end and a lancet mounted within the housing, the lancet being movable along a first axis relative to the housing, the cap comprising:
- a cap body having a proximal end and a distal end, the proximal end of the cap body connecting to the distal end of the housing of the lancing device; and
a contact ring attached to the distal end of the cap body, the contact ring including an opening for a portion of the lancet to pass therethrough, the contact ring having a multi-contoured surface oriented generally about a second axis distinct from the first axis for pressuring the dermal tissue to facilitate expression of a blood sample after lancing the dermal tissue.

Abstract
A cap for a lancing device for lancing dermal tissue is provided. The cap includes a cap body having a proximal end for connecting to the distal end of the housing of the lancing device and a contact ring attached to the distal end of the cap body. The contact ring includes an opening for a portion of the lancet of the lancing device to pass therethrough. The contact ring has a multi-contoured surface oriented generally about an axis distinct from the axis of motion of the lancet. The multi-contoured surface is designed to pressure the dermal tissue to facilitate expression of a fluid sample after lancing the dermal tissue. The fluid sample can include blood, interstitial fluid, or both.

26. A cap for a lancing device for lancing a fingertip, the lancing device including a housing having a proximal end and a distal end and a lancet mounted within the housing, the lancet being movable along the housing, the cap comprising:
-
a cap body having a proximal end and a distal end, the proximal end of the cap body connecting to the distal end of the housing of the lancing device;
a contact ring attached to the distal end of the cap body, the contact ring including an opening for a portion of the lancet to pass therethrough, the contact ring having a multi-contoured surface oriented to create a pressure gradient decreasing towards a puncture on an irregularly curved surface of the fingertips. - View Dependent Claims (27)

29. A lancing device for lancing dermal tissue, comprising:
-
a housing having a proximal end and a distal end;
a lancet mounted within the housing, the lancet being movable along a first axis relative to the housing; and
a cap attached to the distal end of the housing, the cap comprising a cap body having a proximal end connecting to the distal end of the housing and a distal end having a contact ring, wherein the contact ring includes an opening for a portion of the lancet to pass therethrough, and a multi-contoured surface oriented generally about a second axis distinct from the first axis for pressuring the dermal tissue to facilitate expression of a blood sample after lancing the dermal tissue.
