Lancing device and multi-lancet cartridge
First Claim
1. A lancing device for use with a cartridge assembly having an array of lancets, each lancet including a detachable cap, the lancing device comprising:
- a housing for receiving the cartridge assembly;
an indexing ratchet mechanism adapted to sequentially advance the lancets into an active lancet position;
a drive mechanism having a drive member adapted to engage and retract an active-positioned one of the lancets to detach the corresponding active-positioned cap, and to drive the active-positioned lancet along a lancing stroke;
a charger mechanism adapted to retract the drive member;
a cap displacement mechanism adapted to engage and move the active-positioned, detached lancet cap from the lancing stroke path of the active-positioned lancet; and
a slider that is slidable relative to the housing and adapted to actuate the indexing ratchet mechanism, the charger mechanism, and the cap displacement mechanism as the slider is moved between a first position and a second position.

Abstract
A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes a drive mechanism, an activation mechanism, and an advancing mechanism. The advancing mechanism includes a linear-pull slide that is moved in and out to operate an indexing ratchet mechanism, a cam-guided charger mechanism, and a cam-guided lancet cap displacement mechanism. The indexing ratchet mechanism sequentially advances the lancets in the cartridge to an active position. The cam-guided charger mechanism charges the drive mechanism and separates the cap from the active lancet. And the cam-guided cap displacement mechanism moves the separated cap from the lancing stroke path of the active lancet. The activation mechanism then releases the charged active lancet to traverse the unobstructed lancing stroke path to pierce the subject'"'"'s skin at a desired lancing site.

15. A lancing device for use with a cartridge assembly having an array of lancets sequentially advanced to an active position, the lancing device comprising:
-
a housing for receiving the cartridge assembly; a drive mechanism having a drive member adapted to engage and retract an active-positioned one of the lancets to an armed position and to drive the active-positioned lancet along a lancing stroke; and a cam-guided charger mechanism adapted to retract the drive member, wherein the active lancet is capped by an active lancet cap that is detached from the active lancet by the drive member retracting the lancet. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
