A single use lancet device (10) having a housing (20), a lancet (24) with a piercing tip (25) movably disposed in the housing (20) and structured to move between a cocked orientation and a piercing orientation, and a driving assembly structured to move the lancet (24) into the piercing orientation. A retention member and an engagement hub are further provided and structured to be cooperatively engaged with one another upon the lancet being disposed in the cocked orientation so as to maintain the lancet in the cocked orientation until released by an actuation assembly (40). Specifically, the actuation assembly (40) is structured to move between an actuated and an unactuated orientation, movement into the actuated orientation releasing the retention member and the engagement hub from their cooperative engagement with one another and thereby result in movement of the lancet into the piercing orientation. The device also includes a restrictor assembly structured to substantially prevent the actuation, assembly from moving out of the actuated orientation, thereby preventing re-firing of the lancet utilizing the actuation assembly. |
