Abstract
A method and device for sampling biological fluids during collection without opening the functionally closed collection system, thereby compromising the sterility of the collected fluid. A sample bag connected to a fluid line or collection reservoir is filled coincident with fluid collection, then hermetically sealed and physically separated from the collection system using a radio frequency tubing sealer. A vacuum tube collection device is attached to the sample bag to minimize exposure to the fluid during sample handling and processing.
