Single Use Lancing Device
First Claim
1. A lancing device adapted to move a lancet from a cocked position to a puncture position, the lancing device comprising:
- a housing forming an aperture and an opening opposite the aperture, the lancet being adapted to partially extend through the aperture in the housing;
a trigger button located near the opening of the housing, at least a portion of the trigger button being external to the housing;
a drive spring attached to and connecting the lancet and the trigger button, the drive spring being adapted to move the lancet from the cocked position to the puncture position; and
a protective cap removeably attached to the lancet opposite the drive spring, the protective cap engaging the housing when the protective cap is removeably attached to the lancet, wherein the protective cap prevents the drive spring from moving the lancet to the puncture position prior to removal of the protective cap from the lancet.

Abstract
A lancing device comprises a housing, a trigger button, a drive spring and a protective cap. The housing forms an aperture and an opening opposite thereof. A lancet partially extends through the aperture. The trigger button is located near the opening. At least a portion of the trigger button is external to the housing. The drive spring is attached to and connects the lancet and the trigger button. The drive spring moves the lancet from the cocked position to the puncture position. The protective cap is removeably attached to the lancet opposite the drive spring and engages the housing when the cap is removeably attached to the lancet. The cap prevents the drive spring from moving the lancet to the puncture position prior to removing the cap from the lancet.

13. A method for using a lancing device comprising the acts of:
-
providing a housing, a lancet, a plurality of cantilevers, a trigger button, and a protective cap, the housing forming an aperture and an opening opposite the aperture, the lancet being adapted to partially extend through the aperture in the housing, the plurality of cantilevers being located generally parallel to each other adjacent the aperture of the housing, the protective cap being removeably attached to the lancet opposite the trigger button, the protective cap engaging the housing when the protective cap is removeably attached to the lancet; rotating the protective cap to detach the protective cap from the lancet; removing the protective cap from the lancing device through the aperture, the removal of the protective cap causing the lancet to contact the plurality of cantilevers; and depressing the trigger button to cause the lancet to force the plurality of cantilevers apart from one another, the separation of the cantilevers allowing the lancet to move to a puncture position. - View Dependent Claims (14, 15, 16, 17, 18, 19)
