Abstract

A blood sample collection apparatus includes a removable plug adapted to fit within the open end of a blood collection tube. A vacuum tube extends through the plug for evacuating air from the collection tube. A pickup tube protrudes outwardly from the plug for supplying blood to a drop tube extending downwardly from the plug with its lower end positioned within the collection tubes based substantially below the lower end of the vacuum tube. A first filter on the plug is operatively interposed between the lower end of the vacuum tube and the air within the air collection tube for filtering the air drawn through the vacuum tube. A portable hand-held vacuum source is adapted for connection to the vacuum tube for applying a vacuum to the collection tube. The first filter has an exterior surface engaged against the interior periphery of the collection tube, which exterior surface has a plurality of grooves formed therein for filtering air through the grooves between the filter and interior periphery of the collection tube.
