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.

25. A lancing device, comprising:
-
a housing defining a lancet opening;
a spring-driven lancet having a lancing tip, translationally mounted within the housing, and movable between a cocked position and a lancing position, wherein in the lancing position the lancet tip extends through the lancet opening of the housing; and
a lancet reuse prevention mechanism including at least one shoulder and at least one resilient finger engageable by the at least one shoulder after the lancet has moved out of the lancing position to prevent the lancet from being moved back to the cocked position for reuse. - View Dependent Claims (26, 27, 28, 29, 30, 31)

32. A lancing device, comprising:
-
a housing having at least one sidewall and defining a lancet opening;
a spring-driven lancet having a lancing tip and a body from which the lancet tip extends, wherein the lancet is translationally mounted within the housing and movable between a cocked position and a lancing position, wherein in the lancing position the lancet tip extends through the lancet opening of the housing;
a spring that retracts the lancet from the lancing position to prevent the lancet tip from extending through the lancet opening of the housing; and
a lancet reuse prevention mechanism including at least one shoulder and at least one resilient finger, wherein the at least one resilient finger extends outwardly from the lancet body and the at least one shoulder is defined by the housing sidewall, and wherein the at least one resilient finger is engageable by the at least one shoulder after the lancet has moved out of the lancing position to prevent the lancet from being moved back to the cocked position for reuse. - View Dependent Claims (33, 34, 35, 36)
