| 19. A method of continuously filtering a blood product, the method comprising:
receiving a blood product from a blood source at a source flow rate;
transporting the blood product to a filter via a conduit so that an air-blood mix is precluded from entering the filter once
the blood product is received by the filter;
filtering the blood product via the filter to a collection bag, the filter having a filter flow rate;
directing overflow created by a difference between the source flow rate and the filter flow rate to an adjustable volume vessel
in communication with the conduit and joined between the blood source and the filter by a connector, the vessel having a volume;
and
collecting the filtered blood into a collection bag,
wherein the vessel and the collection bag each include a bottom, the vessel and the collection bag being constructed and dimensioned
to enable positioning during filtration such that the connector is below the bottom of the collection bag, and the bottom
of the vessel is above the bottom of the collection bag.
