ABSTRACT:
A blood collection assembly includes a plasma-treated blood collection container and a blood collector which optionally may also be plasma-treated. The collector has a body portion providing a blood passageway between the container and a scoop shaped portion which contacts a puncture wound. A vent in the collector allows air displacement from the container when blood enters. The inside wall of the container has longitudinal ribs molded thereon and an altered surface chemistry characterized by an enhanced oxygen content. The invention includes a method to increase blood flow across the interior surface of a plastic blood collection container comprising plasma treatment of the surface.
