    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.

    摘要： A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float, a ballast assembly longitudinally moveable with respect to the float, and a bellows structure. The bellows structure includes a first end, a second end, and a deformable bellows therebetween. The float is attached to a portion of the first end of the bellows structure, and the ballast is attached to a portion of the second end of the bellows structure. The attached float and bellows structure includes a releaseable interference engagement therebetween. The float has a first density, and the ballast has a second density that is greater than the first density of the float.

    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 first portion and a second portion, a ballast circumferentially disposed about a section of the float, and a deformable bellows defining an open passageway extending between a first end and a second end. The ballast is longitudinally moveable with respect to the float and engaged with the deformable bellows between the first end and the second end. At least a portion of the float is transitionable from a restraint position to a sealed position through the first end of the bellows. The first portion of the float can be positioned within the interior of the deformable bellows in the restraint position, and the first portion of the float can be positioned at an exterior location longitudinally displaced from the deformable bellows in the sealed position.
