Abstract: A track roller includes a body having a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes a first rim portion disposed proximate to the first axial extremity, and a second rim portion disposed proximate to the second axial extremity. An outboard track contact surface is disposed axially proximate to the first rim portion, and an inboard slot is disposed axially proximate to the second rim portion.

Abstract: A system for the disposal of medical waste comprises a sharps container (12) and a nonsharps container (14). The sharps container (12) is interconnected to the nonsharps container (14) for convenience. The sharps container (12) has an open end (18) with a semitortuous path therethrough which helps retain sharps within the sharps container (12). The nonsharps container (14) may also include an attachment holder (16 or 17) which is engaged thereon. A header (20) is positioned in an open end (22) of the nonsharps container (14). Medical nonsharps are disposed of by depositing them within the nonsharps container (14) through the header (20).

Abstract: The present invention is principally directed to an apparatus for unsheathing, resheathing and handling needles. The preferred embodiment includes an elongated housing having an opening at one end that communicates with an internal chamber. Sheath retaining members are disposed substantially adjacent to the opening and can be employed for selective retaining engagement of a sheath that is inserted into the opening. The sheath retaining members may include a deflectable spring member. A gripping portion may be provided in connection with the housing. Appropriate use of the apparatus obviates the need for manual grasping of a needle sheath and provides additional advantages.
