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.

Claims

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, and 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 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; and

wherein the multi-contoured surface comprises a pair of pressure wings.
