          Application 07/952,427                                                      


          claim pending in this application.                                          
                                     BACKGROUND                                       
               Appellants' invention relates to a steam sterilizable                  
          apparatus that includes a container or tube having an inner                 
          surface that may be made of non-PVC plastic material and a                  
          methylene blue solution contained therein or otherwise                      
          associated therewith.  An understanding of the invention can                
          be derived from a reading of exemplary claim 16, which is                   
          reproduced below.                                                           
               16. A steam sterilizable system for housing a body fluid               
          and inactivating a pathogen that may be contained within the                
          system comprising:                                                          
               a container having a therapeutically effective amount of               
          a methylene blue solution that has a pH of less than or equal               
          to 6.3.
