  • Plasma sterilizing process with pulsed antimicrobial agent pretreatment
    Patent number: 5244629
    Abstract: A process for plasma sterilization including exposing an article in a sterilizing chamber to at least one combination sterilizing cycle. Each combination sterilizing cycle includes a pulsed treatment with gaseous antimicrobial agent, removal of the gaseous antimicrobial agent, and a plasma treatment. The pulsed treatment includes one or more pulse-vacuum cycles, each pulse-vacuum cycle includes the steps of evacuating the sterilizing chamber and exposing the article to the gaseous antimicrobial agent with a predetermined pressure profile during a predetermined time. The gaseous antimicrobial agent is preferably carried in a gas mixture with a nonreactive carrier gas. In one embodiment, the predetermined pressure is pulsed. In another embodiment, it is ramped. After the pulsed treatment, the antimicrobial agent is removed by evacuating the sterilizing chamber. The plasma treatment includes exposing the article to a plasma having essentially uncharged, highly reactive free radicals and atoms.
