Multi-lancet cartridge and lancing device
First Claim
1. A lancing device, comprising:
- a plurality of lancets for lancing skin;
a multi-lancet carrier that carries the lancets;
a housing that receives the multi-lancet carrier therein;
an advancing mechanism adapted to advance in a forward direction the lancets of the multi-lancet carrier sequentially into an active position;
a drive mechanism adapted to propel an active-positioned one of the lancets along a lancing stroke path to an extended position to penetrate the skin;
an anti-reverse mechanism housed within the multi-lancet carrier and adapted to permit advancement of the lancets into the active position and to prevent reverse movement of the lancets in a reverse direction opposite from the forward direction, wherein the anti-reverse mechanism includes a series of blocking surfaces and a pawl that sequentially engages the blocking surfaces as the multi-lancet carrier is advanced to prevent reverse direction movement of the multi-lancet carrier; and
an emergency reuse mechanism housed within the multi-lancet carrier and adapted to permit a reusable one of the lancets to be reused, wherein the emergency reuse mechanism includes a ramped surface and a reversement element, the ramped surface is positioned where one of the blocking surfaces of the anti-reverse mechanism would otherwise be and corresponds to the reusable lancet, and when a manual reverse-direction force is applied to the reversement element the pawl slides up the ramped surface and the multi-lancet carrier moves in the reverse direction.

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.
