  • Patent number: 9987408
    Abstract: Objects of the invention are to provide a blood purifier package which shows a less increase in the amounts of extracts from the materials of its blood purifier, particularly of its selective permeable separation membranes, attributed to the deterioration of the same materials with time after exposure to a radioactive ray or an electron ray, and which is therefore highly reliable in safety in use for hemocatharsis, and to provide a process for manufacturing the same. The present invention relates to a blood purifier package obtained by packing a blood purifier which comprises selectively permeable separation membranes as a main component, and this blood purifier package is characterized in that the blood purifier is packed and sealed together with an oxygen scavenger in a packaging material capable of shutting out an external air and a water vapor, under a condition of a relative humidity of above 40% RH at 25° C.
