The present invention is a physical pathogen reduction method and apparatus for controlling or eliminating transfusion-transmittable infections. This purely physical technique does not involve the use of heat, chemicals and/or irradiation, each of which has significant drawbacks in the pathogen reduction of human plasma. The invention inactivates both nonenveloped and enveloped viruses as well as pathogenic bacteria and parasites in units of human plasma, while retaining the natural biological activity. integrity and potency of the treated plasma. The method uses critical, near-critical or supercritical fluids for viral and pathogen reduction of units of donor blood plasma, using novel blood plasma bags. The apparatus is in the form of a bench-top or mobile transportable unit, which can be used in hospitals, blood banks, medical facilities and hot zones in developing countries for the clearance of viruses from human plasma.
The present invention is for a continuous-flow pathogen reduction apparatus and method, based purely on pathogen inactivation physical principles, for controlling or eliminating trans fusion-transmittable infections from emerging pathogens, pandemic viruses, and bioterrorism threats. The invention inactivates both nonenveloped and enveloped viruses as well as pathogenic bacteria and parasites in human plasma and biologies, while retaining the natural bioactivity, integrity and potency of the treated biologic. The method uses critic al, near-critical or supercritical fluids for viral and pathogen reduction of plasma and biologies. The apparatus is designed to rapidly process high volumes of plasma and biologies with high levels of pathogen reduction in a continuous flow fashion.

METHOD AND APPARATUS FOR INACTIVATING PATHOGENS IN UNITS OF WHOLE BLOOD USING SUPERPARAMAGNETIC NANOPARTICLES COATED WITH CHEMILUMINESCENCE REAGENTS AND BROAD-SPECTRUM ANTI-VIRAL THERAPEUTICS
A method and apparatus for reducing or inactivating pathogens in units of whole blood. A plurality of superparamagnetic nanoparticles (SPN) is coated with a mixture of chemiluminescence light-generating compounds and photodynamic broad-spectrum anti-viral compounds, and the mixture in introduced into a bag of whole blood. A rapidly-changing electromagnetic field is applied to the bag to cause uniform distribution of the nanoparticles within the whole blood throughout all regions of the blood bag, including the opaque interior of the bag. The blood is processed for a predetermined processing time period, during which the chemiluminescence light activates the broad-spectrum antiviral capacity of the photodynamic compounds to achieve reduction or inactivation of pathogens throughout the blood bag. After the processing time is elapsed, the nanoparticles are removed from the processed blood by a magnetic field. The processed blood may be washed by conventional means, to remove residual reagents, and transferred into a new, sterile blood bag.
