Systems and methods for pathogen inactivation of blood products

A system for preparing a pathogen-inactivated blood composition, comprising:

• (a) a first fluid path configured to be removably mounted to a device for controlling flow of one or more fluids, wherein the first fluid path is configured to be coupled to a container containing a pathogen inactivation compound (PIC), and configured to be coupled to a processing set, and wherein the first fluid path is configured for transfer of the PIC to the processing set;
• (b) a device comprising one or more components configured to control flow of one or more fluids through the first fluid path;
• and
• (c) the processing set, comprising:
• (i) a container configured for mixing a blood composition with the PIC (mixing container), wherein the mixing container is configured to be coupled to the first fluid path;
• and at least a first storage container, coupled to the mixing container, wherein the storage container is configured for storing the pathogen-inactivated blood composition;
• or
• (ii) a container configured for mixing a blood composition with a PIC (mixing container), wherein the mixing container is configured to be coupled to the first fluid path;
• a second container, coupled to the mixing container, wherein the second container is configured for incubating the blood composition in admixture with the PIC and the second container is configured to be connected to at least a first storage container configured for storing the pathogen-inactivated blood composition;
• or
• (iii) a container configured for mixing a blood composition with a PIC (mixing container), wherein the mixing container is configured to be coupled to the first fluid path;
• a second container, coupled to the mixing container, wherein the second container is configured for incubating the blood composition and the PIC;
• and at least a first storage container, coupled to the second container, wherein the storage container is configured for storing the pathogen-inactivated blood composition;
• or
• (iv) a container configured for mixing a blood composition with a PIC (mixing container), wherein the mixing container is configured to be coupled to the first fluid path;
• a second container, coupled to the mixing container, wherein the second container contains a compound adsorption device (CAD);
• and at least a first storage container, coupled to the second container, wherein the storage container is configured for storing the pathogen-inactivated blood composition.
