Patent ID: 7374870

Claim:
A method for treating a plasma carrying contaminants and cellular matter capable of entraining contaminants, the method comprising the steps of conveying plasma through a first path through a filter that separates cellular matter from the plasma, thereby removing contaminants entrained within the cellular matter, conveying the plasma from the filter through a second path that includes an attached transfer container, mixing within the transfer container the plasma with a photoactive material to form a plasma mixture, conveying a portion of the plasma mixture from the transfer container through a flush path that includes the second path to thereby expose contaminants in the second path to the photoactive material, severing the second path to separate the transfer container from the filter, the transfer container, after severance from the filter, carrying a remnant of the second path, and emitting radiation into the transfer container at a selected wavelength to activate the photoactive material in the plasma mixture and thereby eradicate the contaminant that is free of entrainment by cellular matter.
