  • Lancet device with retractable sharps member
    Patent number: 6540763
    Abstract: A retractable sharps assembly comprising a housing and a sharps unit. The housing comprises first and second open ends and a shoulder proximate the first end. The sharps unit generally comprises a frame, a shelf having a sharps member extending therefrom positioned in the frame, and at least one elastic member extending between the shelf and the forward end. As the frame is inserted into and moved forward in the hollow housing, the shelf is retained by the shoulder such that the elastic member is loaded between the shelf and forward end. A trigger mechanism interacts with the shoulder and disengages the shelf. The load in the elastic member drives the sharps member towards the forward end and through the second end opening, and simultaneously compresses the elastic member. The elastic member thereafter relaxes to retract the sharps member within the housing.
