摘要：
The lancet device includes a housing and a lancet having a puncturing element.The lancet is disposed within the housing and is adapted for axial movementbetween an initial or pre-actuated position wherein the puncturing element isretained within the housing, and a puncturing position wherein the puncturingelement extends through a forward opening in the housing. The lancet deviceincludes a drive spring disposed within the housing for biasing the lancettoward the puncturing position, and a retraction or return spring forreturning the lancet to a position within the housing where the puncturingelement is disposed within the housing. The retraction spring thereaftermaintains engagement with the lancet to assist in preventing the puncturingelement from again projecting outward from the forward opening in the housing.
