Abstract
A sampling device having a lancing apparatus, and optionally a detector and a meter. The lancing apparatus includes a replaceable cartridge of lancets, each lancet having an independent arming and drive mechanism enabling non-sequential and/or simultaneous firing of lancets. A lancet retainer independently associated with each lancet is movable to uncover an opening through which the lancet tip passes, and to release the lancet for activation. The lancets can be actuated in any order, and multiple lancets can be simultaneously actuated, if desired.

12. A lancing device comprising:
-
at least one lancet having a detachable endcap; and
a lancet retainer independently associated with each said at least one lancet, the lancet retainer movable between a first position and a second position, wherein movement of the lancet retainer between the first position and the second position removes the detachable endcap from the lancet and retracts the lancet into a cocked position. - View Dependent Claims (13, 14, 15, 16)

21. A lancing device comprising:
-
a carrier base defining a plurality of guide channels;
a cover mounted on the carrier base to define a housing enclosing the plurality of guide channels and defining a plurality of openings, each opening aligned with an end of one of the guide channels;
a plurality of lancets, each lancet having a body with a sharp tip extending therefrom and an endcap removably positioned over the sharp tip, each lancet associated with one of the guide channels and traversing a path between a retracted position fully within the housing and an extended position wherein at least the sharp tip projects through one of the openings;
a plurality of drive springs, each spring interfacing at a first end with the housing and interfacing at a second end with one of the lancets;
a plurality of lancet retainers, each lancet retainer associated with one of the openings in the housing, and movable between a first position covering that opening and a second position uncovering that opening, and wherein each lancet retainer retains its associated lancet in the first position and releases the associated lancet in the second position; and
a trigger operable to actuate any of the plurality of lancets released by its associated lancet retainer. - View Dependent Claims (22, 23, 24)
