Definitions
- a method for treating blood compositions to inactivate pathogenic microorganisms therein comprises contacting cross-linked polyvinylpyrrolidone-iodine with blood, separating the cross-linked PVP-iodine and the cells therein from the soluble portion of the blood, and removing any residual iodine from the thus-treated soluble portion of the blood.
- the preferred method comprises:
- the cross-linked PVP-iodine has a particle size of about 40-150 microns.
- the active agent for removing pathogenic microorganisms present in blood is the cross-linked complex of polyvinylpyrrolidone and iodine.
- This complex is formed as the reaction product of cross-linked polyvinyl ⁇ pyrrolidone, which is available from International Specialty Products (ISP) , and molecular iodine.
- ISP International Specialty Products
- the cross-linked PVP-iodine is available from ISP as a stable, free-flowing powder which is water-insoluble.
- the preferred cross-linked PVP-iodine product can be characterized as having about 10% available iodine and about 5% iodide in the complex.
- a filter having a porosity equivalent to a 325 mesh screen, i.e. a porosity of 44 microns, was loaded with cross-linked PVP-iodine powder prepared according to the method of the aforementioned U.S. Patent Application, and having a particle size greater than 44 microns, to a bed depth of about 3 inches. Then a blood composition, with any microorganisms therein, was passed through the thus-loaded filter for a contact time of about 2 minutes. The filtrate thus-obtained showed less than 25 ppm of iodine therein. This treatment is effective in killing any microorganisms, including viruses, present in the blood sample.
- the blood cells of the treated blood remained on the filter bed; these blood cells and the cross-linked PVP-iodine are washed with isotonic solution, and transferred to a second filter having a porosity greater than the particle size of the cross-linked PVP-iodine but smaller than the red and white blood cells.
- washing with isotonic solution will separate the cross-linked PVP-iodine from the treated red and white blood cells.
- the filtrate which has dead bacterial cells and dead viruses included therein is subjected to a second filtration to remove the dead bacterial cells present therein.
- the treated soluble portion of the blood is purified by contacting it with cross-linked PVP to remove any residual iodine therein.
- soluble blood is obtained which is substantially free of pathogenic microorganisms and residual iodine.
- a preferred method for accomplishing this is to provide a purification filter loaded with cross-linked PVP, and passing the treated soluble portion of the blood through the loaded filter whereupon the PVP will complex with residual iodine therein on the filter, while the purified, treated soluble portion of the blood passes through.

Abstract
On décrit un procédé de traitement du sang et de ses compositions permettant d'éliminer des microorganismes pathogènes présents dans celui-ci. L'invention consiste à mettre en contact avec du sang le complexe réticulé constitué de polyvinylpyrrolidone et d'iode (PVP-I2) et à séparer de la partie soluble du sang le complexe réticulé PVP-iode et les globules qu'il contient. Le procédé préféré consiste à charger le complexe réticulé constitué de polyvinylpyrrolidone et d'iode sur un filtre présentant une porosité inférieure soit à la grosseur des particules dudit complexe réticulé de PVP-iode, soit aux globules sanguins de la composition, à mettre en contact avec le sang le lit filtrant ainsi chargé afin de rendre inactifs les microorganismes qu'il contient, à faire passer la partie soluble traitée de la composition sanguine dans le filtre, à récupérer les globules sanguins ainsi traités restant sur le filtre, et à purifier la partie soluble traitée de la composition sanguine en la mettant en contact avec le complexe réticulé de PVP afin d'éliminer tout résidu d'iode s'y trouvant.
