Abstract: The invention relates to a method for inactivating pathogens such as bacteria and viruses and/or leucocytes in thrombocyte concentrations by irradiation in flexible containers with ultra-violet light using agitation. The blood product is packaged in a flexible bag to permit the intermixing of the fluid by agitation (tilting, rotation, translation). This is also promoted by the filling of the bag to a maximum 30% of the filling capacity.

Abstract: An aqueous solution for suspending and storing cells, especially erythrocytes, and containing sodium chloride, glucose or fructose, adenine, and a sugar alcohol, the sugar alcohol being sorbitol or xylitol is employed to further improve the storage time and hence the survival rate of the cells and even reduce the hemolysis rate of erythrocytes in packed red blood cells.

Abstract: A bag suitable for the storage, deep-freezing and transfusion of blood and blood components formed of a calendered or extruded foil of plasticizer-free polyurethane of a thickness of about 0.1-0.5 mm, a Shore hardness A of about 60-85, temperature resistance up to about 160.degree. C. and down to about -196.degree. C. without change of properties. The bag can be used in combination with fittings and tubings of the same material to provide an overall plasticizer-free polyurethane system. The bag can be sterilized, is capable of low temperature storage, and exhibits other desirable properties without affecting the quality of its contents.

Abstract: A microfiltration device for the filtration of coagula and microaggregates from blood and blood components. The device contains a filter chamber with attaching nozzle, a filter cone containing truncoconical filter elements arranged in cascade with diminishing pore size and diminishing surface area, a drip chamber and a tailpiece. The filter chamber and filter cones have different tapers and are at a specific distance apart, the taper of the filter cone from inlet to outlet being greater than the taper of the filter chamber. The filter cone has up to four filter elements, and a spacer which extends into the filter element of smallest pore size and surface area and supports same. Each of the filter elements has at least two opposed ribs running from the base to the apex of the truncated cone. The spacer is constructed such that it serves simultaneously for the support of the ribs and for the support of the filter fabric of the smallest filter element. The device has a capacity of less than 100 ml.

Abstract: In a blood bag assembly comprising a blood bag and means for connecting the interior of the bag with the interior of a second bag, the improvement wherein said connecting means comprises a coupling composed of a connecting portion, a break-off portion, and a break-off point, the coupling being joined directly at the upper edge of the bag and terminates substantially evenly therewith, the break-off portion will be inside of the bag after it is broken off.
