Title:
METHOD FOR STERILIZING PACKAGES OF MEDICAL SUPPLIES
Document Type and Number:
WIPO Patent Application WO/1998/058842
Kind Code:
A1
Abstract:
A sterilization method which comprises the step of enclosing a medical supply together with a deoxidizer in an oxygen-impermeable packaging material to give a package, the step of sterilizing the package by radiation while maintaining the atmosphere in the package in a state with a reduced oxygen concentration, and the step of, after the completion of the radiation sterilization, further reducing the oxygen concentration with the deoxidizer while maintaining the package under the sterile conditions. In this method, the oxygen concentration can be maintained at a low level during the sterilization while sustaining the sterilization efficiency of the radiation sterilization and the oxygen concentration is also maintained at a low level during the subsequent storage, which makes it possible to inhibit the formation of harmful by-products, thus ensuring the provision of highly safe medical supplies.
