摘要： A sterilization system applies power to a plasma within a chamber to remove gas or vapor species from an article. The sterilization system includes a power feedback control system for controlling the power applied to the plasma. The power feedback control system includes a current monitor adapted to produce a first signal indicative of a current applied to the plasma within the chamber. The power feedback control system further includes a voltage monitor adapted to produce a second signal indicative of a voltage applied to the plasma within the chamber. The power feedback control system further includes a power control module comprising a programmable digital signal processor. The digital signal processor is adapted to receive and process the first signal and the second signal by multiplying the current and the voltage and producing a third signal indicative of the product of the current and the voltage. The power feedback control system further includes a plasma generator coupled to the power control module and adapted to adjust, in response to the third signal, the power applied to the plasma within the chamber.

摘要： A method for sterilizing medical devices and similar instruments in diffusion-restricted containers is provided. The sterilization method includes placing a liquid solution containing vaporizable germicide such as hydrogen peroxide into the diffusion-restricted container and vaporizing the germicide. The containers can be attachable and detachable to a sterilization system, and used as a vacuum chamber. An attachable/detachable container containing an article to be sterilized can be nested with a second container, and the article and inside and outside of the inner container are sterilized. The sterile article inside the nested containers can be transported and the sterile inner container with the sterilized article can removed from the outer container and placed in a sterile environment without contaminating the sterile environment. The sterile article can then be removed from the sterile container and utilized. Alternatively, the sterilization method may include introducing germicide vapor into an attachable/detachable container.
