Abstract

PURPOSE:To achieve higher quality by performing a high pressure steam sterilization treatment of a medical apparatus as wrapped with a sterilized bag having a steam permeable sheet to eliminate coloring and discoloring. CONSTITUTION:A medical apparatus 4 filled with a preservation liquid wrapped with paper and having a label applied thereon is wrapped with a sterilizing bag 1. The sterilizing bag 1 is carried into a high pressure steam sterilizing chamber and a high pressure steam sterilization treatment is performed for 20min. under a pressure of 1.2kg/cm<2> at 121 deg.C. The sterilizing bag 1 is housed into a drier to dry at 70 deg.C to 80 deg.C for 120min. and water drops adhering to the surface of the medical apparatus 4 in the sterilizing bag 1 are driven out via a steam permeable sheet 3. After the sterilizing bag 1 is cooled down to the room temperature, the body 2 is sealed up along a line A-A to seal the medical apparatus 4 in the sterilizing bag 1 completely while the steam permeating sheet 3 is cut off.
