Abstract: A method of using a vacuum chamber to assist in detecting and removing moisture from an instrument having a lumen, e.g., an endoscope is disclosed. Second derivatives of pressure with respect to time are calculated and differences therebetween summed. These summations may be compared to a threshold value to determine whether residual moisture remains on the instrument in the chamber. The vacuum chamber may include a rack for hanging instruments having lumens, such as endoscopes.

Abstract: A sterilization system includes a sterilization chamber, a processor, and a sterilization module. The sterilization module includes a frame assembly, an extraction assembly, and a carriage assembly. The extraction assembly is configured to extract a sterilant fluid from a cartridge and transfer the sterilant fluid to the sterilization chamber. The carriage assembly includes a motor, a carriage body, and a translating flag. The carriage body is configured to receive the cartridge. The translating flag is configured to move from a first position to a second position relative to the carriage body in response to the carriage body receiving the cartridge. The sensor is configured to detect movement of the translating flag from the first position to the second position.

Abstract: A self contained biological indicator is disclosed having a housing and an ampule disposed within the housing, the ampule having a first dome, a second dome and a sidewall. A cap may be coupled to the housing. The cap may include a projection that may be coupled to the ampule by, e.g., a friction fit. An insert may be disposed within the housing. The insert may include a well within which at least a portion of the bottom dome of the ampule may be disposed. The insert may also include a ramp that is angled relative to the central longitudinal axis of the ampule. The second dome of the ampule may contact the ramp. The insert may also include an arm or finger that extends above the well and has a stress concentrator disposed thereon such that it is also disposed above the second dome of the ampule and adjacent to the sidewall of the ampule.

Abstract: A method of sterilizing medical instruments using a vacuum chamber connected to reservoir by a valve in a closed state is disclosed that includes placing instruments in a non-sterile state into a sterilization pack, opening a chamber, placing the pack into the chamber, closing the chamber, withdrawing a first volume of air from the chamber, changing a volume of liquid water into vapor, opening the valve, introducing sterilant into the chamber, introducing a second volume of air into the chamber, opening the chamber, removing the pack from the chamber, and removing the instruments in a sterile-state from the pack. The process may further include the steps of repeatedly determining pressure within the chamber, calculating second-derivative values of pressure with respect to time, and determining whether any local maxima exist in a plot of second derivative values that correspond to pressures above and/or below the triple-point pressure of water.

Abstract: A method of using a vacuum chamber to assist in detecting moisture on an instrument, removing moisture from the instrument, and confirming dryness of the instrument is disclosed. The method may include the steps of opening a vacuum chamber; placing an instrument into the chamber, closing the chamber, withdrawing a first volume of air from the chamber; changing a volume of liquid water into vapor, introducing a second volume of air into the chamber, withdrawing the second volume of air from the chamber, changing a second volume of liquid water into vapor, introducing a third volume of air into the chamber, opening the chamber, and removing the instrument from the chamber in a dry state.

Abstract: A method for tracking sterilant cassettes within a sterilizer involves reading for the presence of a cassette within a cassette processing area of the sterilizer by reading a first visual code on the cassette with a scanner and with the same scanner reading for the presence of a second visual code in a spent cassette collection box. Upon successfully reading the second visual code it is thus known that the spent cassette collection box is present and has capacity to receive the cassette.
