Abstract
An apparatus for collecting biological fluids and handling the same into a sample for testing comprising a tubular container having open ends, one of which is removably secured to a collection storage unit. A shuttle assembly constructed of a cylindrical hollow piston defining a chamber, a top cover covering one end of said piston and a second cover with an aperture and a connector covering the second end of the piston is slidably mounted in the tubular container. An 'O' ring is mounted on the exterior surface of the piston to form a fluid tight seal between the 'O' ring and the interior surface of the tubular container with the connector being removably secured to a resin/sample container so that movement of the piston in the tubular container carries the resin/sample container into the collection storage unit and forces fluid collected in the tubular container to flow through the resin/sample container.
