Abstract
A 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 controls an indexing mechanism, a charger mechanism, and a cap-displacement mechanism. The indexing mechanism sequentially advances the lancets to an active position The charger mechanism charges the drive mechanism and removes the lancet caps And the cap-displacement mechanism moves the separated caps from the lancing stroke path The activation mechanism then releases the charged lancet to traverse the lancing stroke path to pierce the subject's skin Some embodiments include an anti-reverse mechanism to prevent reuse of the lancets, and some include an emergency lancet reuse mechanism that permits emergency reuse of the last lancet And some embodiments include a movable depth-control wall for providing control and adjustment of the lancing penetration depth.
