Abstract: In a low temperature hydrogen peroxide gas plasma sterilizer, plasma within the sterilization chamber contributes to the sterilization process and decomposes the sterilant used at the end of a sterilization programs. The plasma however the must be properly profiled otherwise undesired surface etching may occur on the sensitive medical apparatus. This application describes a novel plasma control method and apparatus which minimize the harmful side effects plasma on the medical apparatus during a sterilization program.

Abstract: In a low temperature hydrogen peroxide gas plasma sterilizer, the accurate control of concentration of the hydrogen peroxide sterilant is an important factor in determining reliability and sterilization efficacy of the sterilization process. The present application describes sterilizers, and sterilization methods, which use a novel injector-concentrator arrangement which allows accurate concentration of the sterilant performed concurrently with the sterilization process. This process enables the device to sterilize wide range of sensitive equipment within a shorter sterilization cycle.

Abstract: In a hydrogen peroxide gas plasma sterilizer, the concentration of the hydrogen peroxide sterilant is an important factor in determining sterilization efficacy. The present application describes sterilizers, and sterilization methods, which use a novel injector-concentrator arrangement. This arrangement provides accurate control of concentration of the liquid-phase hydrogen peroxide, prior to vaporization of the liquid sterilant into the sterilization chamber. This increases the reliability and efficacy of the sterilization cycle.
