Abstract:
1. A blood purifier package comprising (a) a blood purifier comprising selectively permeable separation membranes as a main component, wherein the moisture content of the selectively permeable separation membranes is not lower than 1.0 mass % and not larger than 2.1 mass %, wherein the selectively permeable separation membranes comprise a polysulfone-based polymer containing polyvinyl pyrrolidone, (b) an oxygen scavenger, and (c) a packaging material capable of shutting out external air and water vapor, which packaging material is sealed and defines a space containing an atmosphere, wherein the oxygen permeability of the packaging material is not larger than 1 cm the water vapor permeability of the packaging material is not larger than 5 g/(m the blood purifier and the oxygen scavenger are within the space defined by the sealed packaging material, the atmosphere in the space has a relative humidity of not less than 68% RH at 25° C, and the blood purifier has been sterilized by exposure of the blood purifier within the sealed packaging material to a radioactive ray, an electron ray, or both a radioactive ray and an electron ray, wherein the oxygen concentration within the sealed packaging material during sterilization is not higher than 5%.
