ABSTRACT:
A suction metering and mixing device is disclosed for collecting body fluids such as blood and simultaneously mixing an anticoagulant therewith. The device includes a suction passage having an inlet end and an opposite end for connection to a vacuum supply. A chamber is provided for controlling the flow of anticoagulant and includes an inlet port defining a passage for entry of anticoagulant into the chamber and a diaphragm dividing the chamber into first and second portions wherein the diaphragm is in contact with the inlet port to prevent flow of anticoagulant into the first chamber portion. A fluid connection is provided between the suction passage and the second chamber portion whereby a vacuum may be supplied to the second chamber portion from the suction passage and the diaphragm is drawn away from the inlet port to allow anticoagulant to flow into the first chamber portion. The anticoagulant then flows through a supply tube to a position adjacent to the inlet to the suction passage where it is mixed with blood entering the suction passage.
