Abstract:
1. An antimicrobial photodynamic therapy method for the depletion, elimination, or inactivation of microbe-infused blood and blood products without adversely affecting the essential elements of their biological activity comprises the steps of: a. collecting a blood; b. separating whole blood into blood components if necessary; c. mixing a photosensitizer with blood or blood components comprising a treatment fluid in a sterile light-transparent container bag; d. placing said container bag into a treatment device bag holder; e. setting said holder into sliding motion, rotating motion or a combination thereof; f. illuminating said treatment fluid at a wavelength appropriate for the selected photosensitizer to form active microbe-free treatment fluid; g. depleting excess and/or un-activated photosensitizer and/or residual fragments by passing the active microbe-free treatment fluid through a photosensitizer-absorber unit comprising a plastic housing filled with tiny porous beads and larger sponges; and h. collecting and storing the treatment fluid, after undergoing steps f and g, in a sterile fashion until further use.
