Claim Text:
1. A lancet device comprising: a housing comprising a forward end and a rearward end and an internal contact within the housing; an actuation member at least partially disposed within the housing, the actuation member sized for movement within a portion of the housing; a lancet structure comprising a puncturing element, the lancet structure disposed within the housing and adapted for movement between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein the puncturing element extends through the forward end of the housing, a drive spring disposed between the rearward end of the housing and the lancet structure for biasing the lancet structure toward the puncturing position; and a lever element pivotal about a fulcrum, the lever element providing interference engagement with the lancet structure and retaining the lancet structure in the pre-actuated position and adapted to retain the lancet structure against the bias of the drive spring, the lever element comprising a pair of levers engaging the lancet structure on opposing sides of the lancet structure; wherein movement of the actuation member toward the lever element causes the internal contact to contact a portion of the lever element to pivot the lever element about the fulcrum, the pivoting of the lever element moves the lancet structure toward the rearward end of the housing to at least partially compress the drive spring and the pivoting of the lever element releases the interference engagement between the lever element and the lancet structure, permitting the drive spring to drive the lancet structure through the housing toward the puncturing position.
