1. A lancet device, comprising:

  • a housing;

    a shield coaxially and movably associated with the housing;

    a puncturing element 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 a forward end of the housing; and

    a removable sterile tab member associated with the shield,wherein the shield is movably associated with the housing to move from a first position extending outward from the housing to a second position at least partially retracted into the housing and wherein the sterile tab member comprises a closed distal surface and a depending hollow skirt protruding proximally relative to the distal surface, the depending hollow skirt at least partially encompassing the shield such that a distal lip of the depending hollow skirt contacts a terminal surface of the shield and a terminal proximal surface of the depending hollow skirt contacts a terminal surface of the housing to prevent axial movement of the shield relative to the housing and to enclose a forward opening of the housing with the depending hollow skirt and a forward opening of the shield with the distal surface of the tab member.
