CAP DISPLACEMENT MECHANISM FOR LANCING DEVICE AND MULTI-LANCET CARTRIDGE

摘要

A medical lancing device including a replaceable multi-lancet cartridge (10) . The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap (28 ) from the active lancet (20), and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap (28) out of the travel path of the active lancet (20). In a first example embodiment, the ca p displacement mechanism includes a cantilevered spring arm (50) that displace s the detached cap of the active lancet. In a second example embodiment, the c ap displacement mechanism includes a spring-biased cam-driven plunger (232) tha t displaces the detached cap of the active lancet. Then an activation mechanis m releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.
