    摘要： An improved apparatus and method for measuring the concentration of hydrogen peroxide vapor or gas in a sterilization chamber. The hydrogen peroxide is measured spectrophotometrically in the ultraviolet region between 200 and 400 nm. Because water vapor does not absorb in the ultraviolet region, it does not interfere with the determination of the concentration of the hydrogen peroxide vapor. Although organic compounds have absorbances in the ultraviolet region, the organic compounds are removed by evacuating the sterilization chamber to low levels before doing the hydrogen peroxide determination. The ultraviolet light source is either a low pressure mercury vapor lamp with an emission at 254 nm or a deuterium lamp with an optical filter selective of 206 nm light. A movable gas cell can be used to measure the hydrogen peroxide concentration at various areas in the sterilization chamber. The measurement system can be combined with a feedback loop to control the concentration of hydrogen peroxide in the sterilization chamber.

    摘要： A method for cleaning and sterilizing a medical device comprises the steps of: a) placing the device into a container, b) cleaning the device with a cleaning solution, c) rinsing the device with rinse solution, d) treating the device with a liquid sterilant, e) vaporizing the liquid sterilant in the container thereby simultaneously sterilizing and drying the device, and providing a sterile, dry product without further rinsing. The method further comprises retaining a predetermined amount of the liquid sterilant in the container prior to step e). Step e) can be conducted under a diffusion restricted environment, or by reducing pressure to a first predetermined pressure followed by further reducing the first pressure to a predetermined second pressure, or at controlled pump down rate.

    摘要： A method and an apparatus for sterilizing a lumen device. A lumen and a container having an interface on a wall of the container are enclosed in a chamber. The lumen is placed across the interface so that one end of the lumen is in the container and the other end is in the chamber. Germicide is introduced into the chamber, and a pressure difference is created between the two ends of the lumen, so that the germicide flows through the lumen. The lumen may alternatively be placed across an interface which separates the chamber into two areas. Germicide is introduced into the chamber, and a pressure difference is created between the two areas of the chamber, causing the germicide to flow through the lumen.

    摘要： A system and a method for sterilizing a lumen device involve a container in a chamber and a source of germicide. The container has an interface separating the container into two compartments and a communication port which provides fluid communication between the container and the chamber. The lumen device extends across the interface, and the two compartments are in fluid communication with each other through the lumen device. The lumen device is sterilized when the germicide flows from compartment to compartment through the lumen device.
