Prefilled injector package and sterilizing or disinfecting method therefor

Abstract

The present invention relates to a prefilled injector package comprising a prefilled injector having a syringe body filled with a medicine; and a packaging material for hermetically packaging the prefilled injector, the packaging material being brought into close contact with at least the syringe body; and a method for sterilizing or disinfecting the prefilled injector package, which comprises the steps of packaging the prefilled injector with the packaging material such that the packaging material is brought into close contact with at least the syringe body; and heat-treating the prefilled injector package to simultaneously sterilize or disinfect an injector body and the medicine filled therein. According to the present invention, the injector body and the medicine filled therein is sterilized or disinfected at the same time by subjecting the prefilled injector package to only one heat treatment, and the deposition of water is prevented onto injection nozzle or cap upon sterilization using steam or hot water.

What is claimed is:  
     
         1 . A prefilled injector package comprising: 
 a prefilled injector having a syringe body filled with a medicine; and    a packaging material for hermetically packaging the prefilled injector, wherein    said packaging material is brought into close contact with at least the syringe body.    
     
     
         2 . A prefilled injector package according to  claim 1 , wherein said prefilled injector is hermetically packaged by vacuum packaging or shrink packaging.  
     
     
         3 . A prefilled injector package according to  claim 1 , wherein said packaging material is a film having a gas-barrier property, a moisture-proof property or both of gas-barrier property and a moisture-proof property.  
     
     
         4 . A prefilled injector package according to  claim 1 , wherein said packaging material is a multi-layered film having a gas-barrier property.  
     
     
         5 . A prefilled injector package according to  claim 1 , wherein said packaging material is a film having an easy-peel property.  
     
     
         6 . A prefilled injector package according to  claim 1 , wherein said medicine is a viscoelastic medicine.  
     
     
         7 . A prefilled injector package according to  claim 1 , wherein said medicine includes hyaluronic acid compounds.  
     
     
         8 . A method for sterilizing or disinfecting a prefilled injector package according to  claim 1 , comprising: 
 packaging a prefilled injector having a syringe body filled with a medicine, with a packaging material such that the packaging material is brought into close contact with at least the syringe body; and    heat-treating the prefilled injector package to simultaneously sterilize or disinfect an injector body and the medicine filled therein.
