Patent ID: 7947057

Claim:
A lancet device, comprising: a housing having a proximal end and a distal end; a cover having an opening, being removably mountable to the proximal end of the housing, and having a surface for contacting the skin of a user to position the lancet device; a lancet holding member arranged within the housing, the lancet holding member being capable of holding a lancet; a biasing element structured and arranged to bias the lancet holding member toward the proximal end of the housing; the biasing element having one end contacting a portion of the lancet holding member and another end contacting a portion of the housing; a trigger structured and arranged to contact a portion of the lancet holding member, wherein, during triggering of the lancet device, movement of the trigger releases the lancet holding member so that it can move towards the proximal end by the biasing element; a rotatably mounted depth adjustment mechanism arranged behind the biasing element; a protrusion that interacts with a portion of the lancet holding member to adjust a length of travel of the lancet holding member to allow needle penetration depth adjustment; a movably mounted end cap associated with the lancet holding member and being arranged distal of the biasing element; and the end cap comprising a proximal portion that extends into the depth adjustment mechanism and into the distal end of the housing, and a distal portion that extends outside of the depth adjustment mechanism and the distal end of the housing, wherein the lancet device is cocked by pulling the end cap away from the housing.
