ABSTRACT:
A lancet device used to pierce a user's skin and including a lancet with a body portion and a piercing tip, a primary housing, a cover assembly with a piercing opening and structured to be matingly coupled with the primary housing to define an interior chamber, and a lancet receiving assembly movably disposed within the interior chamber and structured and disposed to hold the lancet during its driven movement between a cocked orientation, a piercing orientation and a fired orientation. The lancet device further includes a retention member including a pair of elongate fingers, and an engagement hub disposed in the interior chamber and structured to be cooperatively engaged by inwardly depending protrusions on the elongate fingers when the lancet receiving assembly is in the cocked orientation so as to maintain the lancet receiving assembly in the cocked orientation until the retention member is affirmatively released from its cooperative engagement with the engagement hub by an exteriorly actuatable actuation assembly which urges the elongate fingers out of their engagement with cooperative structure on the engagement hub.
