US 9,802,189 B2 · Density phase separation device

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.

Dependent claims

A device for separating a fluid sample within a collection container, comprising:

a separator having a through-hole defined therethrough along a through-axis, the through-hole allowing fluid to pass therethrough, the separator comprising:
a float, having a first density;
and
a ballast, having a second density greater than the first density, wherein a portion of the float is connected to a portion of the ballast,
wherein the separator has a center of mass and a center of volume that is offset from the center of mass, and
wherein the separator has a first diameter taken along a first side of the through-hole which is different than a second diameter taken about a second opposite side of the through-hole, and wherein the first and second diameters are parallel with the through-axis.
