Abstract:

A centrifuge tube assembly includes an elongate tubular receptacle having a capped upper end. The capped upper end includes a single inlet/outlet port formed therethrough for communication with an interior of the tubular receptacle. A flexible aspiration pipe is communicably engaged with the inlet/outlet port for extending longitudinally through the cylindrical receptacle. A sealing diaphragm is attached to a distal end of the pipe. The diaphragm is longitudinally movable within the tubular receptacle and sealably interengages an interior wall of the receptacle. Biological products are introduced into and aspirated from the receptacle below the diaphragm by the fluid conducting pipe.

Abstract:

A dual lumen syringe includes a body having a pair of elongate cavities or lumens formed therein. A directional valve is associated with each lumen. The valve is alternated between the first position wherein the lumen is communicably connected to a fluid inlet and a second position wherein the lumen is connected with a fluid outlet. There are a pair of elongate plungers, which are fixedly interconnected by a handle. Each plunger is received and longitudinally slidable in a reciprocating manner through a respective lumen. The valves are switched to a first position wherein the lumens are interconnected with the fluid inlets and the plunger is retracted to aspirate fluids through the respective inlets and into the lumens. The valves are then switched to a second position to communicably interconnect the lumens with the outlets. The plungers are then simultaneously driven inwardly through the respective lumens to drive the fluids simultaneously through the outlets to a dispensing tip permanently connected to the body and in communication with the outlets.
