    摘要： A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

    摘要： A mechanical separator (40) for separating a fluid sample into first and second phases within a collection container (82) is disclosed. The mechanical separator may have a separator body having a through-hole (46) defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float (42), having a first density, and a ballast (44), having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumf erentially disposed about at least a portion of the separator body. The separator can be used for example for the separation of blood components.

    摘要： A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float having a passageway extending between first and second ends thereof with a pierceable head enclosing the first end of the float, a ballast longitudinally moveable with respect to the float, and a bellows extending between a portion of the float and a portion of the ballast. The bellows is adapted for deformation upon longitudinal movement of the float and the ballast, with the bellows isolated from the pierceable head. The float has a first density and the ballast has a second density greater than the first density. The bellows is structured for sealing engagement with a cylindrical wall of a tube, and the pierceable head is structured for application of a puncture tip therethrough. The separation device is suitable for use with a standard medical collection tube.
