  • Method of inactivating virus in circular blood and its applications in treating viral diseases
    Patent number: 8808977
    Abstract: The present invention relates to a method for illuminating the viruses in a circulatory blood, comprising the following steps of: 1) Adding an anticoagulant into a whole blood source and establishing a circulation system for the whole blood source; 2) Withdrawing the whole blood with the anticoagulant into a plasma-separating device for a separation, when finished, directly pumping the red-blood cells back into the whole blood source and transporting the plasma into a mixing transport pump after the separation; 3) Meanwhile, pumping a photosensitizer methylene blue into the mixing transport pump so that the methylene blue is mixed with the plasma and pumped together into a plasma container; 4) Using an illumination device to illuminate the plasma in the plasma container for virus illumination, and pumping the virus-illuminated plasma into a removing device for removing off the photosensitizer; 5) The methylene blue being absorbed by the removing device and the plasma illuminated being transfused back into the
