Abstract: A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, 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 circumferentially disposed about at least a portion of the separator body.

Abstract: A biological sample containment system and method are provided that include a container for storing the biological sample and an indicator affixed to the container for displaying at least one measured characteristics of the container or sample, wherein measurement of the characteristic is commenced by activation of the indicator. In another embodiment of the invention, a biological sample containment system and method are provided that include a container for storing the biological sample and a colored scale affixed to the container, wherein the colored scale facilitates identification of at least one characteristic of the biological sample. In yet another embodiment of the invention, a biological sample containment system and method are provided that include a container for collecting a biological sample and a label affixed to the container, wherein information relating to the biological sample or container is situated on the label.

Abstract: 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.

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.

Abstract: A system is provided which may be used for collecting and testing fluid samples at a patient point of care location. A disposable collection and containment device is provided for collecting a fluid sample directly into a containment chamber containing testing mechanisms using an integrated collection mechanism for immediate evaluation of the collected sample. The integrated collection cartridge contains an array of electrical contacts, electrochemical sensors and circuitry configured to electrically couple with an analytical device, such as a personal digital assistant (PDA) or a stand-alone computer workstation, which controls the testing of the fluid sample within the cartridge and provides a rapid indication of test results at the point of care.

A disposable cartridge and collection device is provided for collecting a fluid sample directly into a cartridge containing testing mechanisms for immediate evaluation of the collected sample. The cartridge contains an array of electrical contacts, electrochemical sensors and circuitry configured to electrically couple with a hand-held analytical device, such as a personal digital assistant (PDA) or a stand-alone computer workstation, which controls the testing of the fluid sample within the cartridge and provides a rapid indication of test results at the point of care.
