ABSTRACT:
Embodiments of a multiple draw syringe are disclosed which may be used to draw multiple samples of fluid from a human or animal or other source. The multiple draw syringe includes a protective barrel, a plunger tray, and a needle manifold. Evacuated sample tubes may be placed in the plunger tray and the plunger tray inserted into the rear of the protective barrel. The needle manifold includes a forward projecting drawing needle and a plurality of rearward projecting specimen needles. The needle manifold may be inserted into the front of the protective barrel. The drawing needle may be inserted into a vessel from which a sample is to be taken. The plunger tray may then be pressed forward causing the specimen needles to penetrate the stoppers on the evacuated tubes and placing the vessel in operational contact with the interior of the tubes. The fluid flows through the needle manifold into the tubes. The plunger tray may then be pulled rearward and removed which causes the needle manifold to be pulled rearward and the needle manifold is locked within and completely enclosed by the protective barrel. The needle manifold and the protective barrel may then be safely discarded.
