Patent number: 7972558Abstract: A method and an apparatus for sterilizing packaging material for use in packaging for protein containing products, such as food products or medical drugs. The packaging material is sterilized by irradiating it using a beam of ionizing radiation, such as an electron beam or a beam of gamma rays.

Patent number: 7899681Abstract: A system for electronic management of information relating to sterilization and high level disinfection process monitoring generates electronic sterilization record for sterilized and high level disinfected loads, and optically scans sterilization monitors associated with the sterilized loads. The system stores a digital representation of each scanned sterilization monitor, and associates the digital representation with the electronic sterilization record. The electronic sterilization record also may contain a variety of information including a sterilization status data entered by a user. The system permits a user to review both the sterilization status information and the digitized representation of the sterilization monitor online to verify accuracy. In this manner, a representation of the actual sterilization monitor can be stored and retrieved when desired for verification of result, audits and other quality review activity.Type: GrantFiled: March 29, 2002Date of Patent: March 1, 2011Assignee: 3M Innovative Properties CompanyInventors: Kevin R. Katzenmaier, Janet M. Prust, Andrew C. Daus
