Abstract
A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap from the active lancet, and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap out of the travel path of the active lancet. In a first example embodiment, the cap displacement mechanism includes a cantilevered spring arm that displaces the detached cap of the active lancet. In a second example embodiment, the cap displacement mechanism includes a spring-biased cam-driven plunger that displaces the detached cap of the active lancet. Then an activation mechanism releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.
