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.
