Patent Images
1. A lancing device, comprising:
- (a) a housing containing a lancet;
(b) a lancet driver to couple with and move the lancet within the housing;
(c) a skin interface cap having an opening defined therein to expose at least part of the lancet when moved by the driver; and
(d) a sliding frame coupled to the housing and to the skin interface cap, said frame being adjustable relative to the housing for accordingly adjusting said cap relative to the housing, whereby an extent to which the lancet is exposed through the opening is adjustable by adjusting the sliding frame.

Abstract
A lancing device includes a housing for containing a lancet. A lancet driver couples with and moves the lancet within the housing. A skin interface cap has an opening defined therein to expose at least part of the lancet when moved by the driver. A sliding frame is coupled to the housing and to the skin interface cap. The frame being adjustable relative to the housing for accordingly adjusting said cap relative to the housing, whereby an extent to which the lancet is exposed through the opening is adjustable by adjusting the sliding frame.

13. A method of lancing skin and exposing blood to perform an assay, comprising:
-
(a) providing a housing containing a lancet, a lancet driver, and a sliding skin interface cap coupled to the housing and having an opening defined therein; (b) adjusting a lancet penetration depth by sliding the skin interface cap relative to the housing and thereby moving the opening relative to the lancet or lancet driver or both; (c) coupling the lancet to the lancet driver; (d) moving the lancet by moving the lancet driver; (e) exposing at least part of the lancet through the opening in the skin interface cap to pierce skin that is provided at the opening at a depth selected by the sliding of the skin interface cap. - View Dependent Claims (14, 15, 16)
