Abstract
Processes and systems for combining multiple units of a biological fluid in independent containers into a single container are disclosed.
Claims17
A method for processing biological fluid comprising:
- introducing gas through at least one downstream gas inlet through a pooling assembly into a first one of a plurality of upstream source containers of biological fluid while preventing the flow of gas from the gas inlet into a receiving container for receiving the biological fluid, wherein the gas inlet is interposed between the plurality of upstream source containers and the receiving container, and wherein the pooling assembly is interposed between the gas inlet and the plurality of upstream source containers;
- introducing gas through the downstream gas inlet and through the pooling assembly into a second one of the plurality of upstream source containers of biological fluid while preventing the flow of gas from the gas inlet into the receiving container;
- passing the biological fluid from the first upstream source container through the pooling assembly, and through a leukocyte depletion device to leukocyte deplete the fluid from the first container, wherein said leukocyte depletion device is interposed between the gas inlet and the receiving container;
- passing the biological fluid from the second upstream source container through the pooling assembly, and through the leukocyte depletion device to leukocyte deplete the fluid from the second container;
- and,
- passing the leukocyte depleted biological fluid into the receiving container.

- passing the biological fluid from the plurality of upstream source containers through a pooling assembly to the receiving container;
- exhausting gas ahead of the biological fluid;
- and
- introducing gas through the gas inlet behind the biological fluid to maximize recovery of the biological fluid in the receiving container.
