Abstract
A lancing device including a spring-driven lancet translationally mounted within a housing. The lancet has at least one resilient finger extending outwardly therefrom and engageable within a cooperating recess formed in the housing to prevent re-use of the lancing device. A depth-adjustment knob is optionally included for contacting the housing to limit the travel of the lancet and thereby control the depth of penetration.
