Abstract: Systems and methods for controlling humidity. Methods can include providing a chamber configured to receive objects to be sterilized; injecting a first quantity of water into the chamber; determining a pressure rise and a pressure drop in the chamber resulting from the first injection; calculating an absorption ratio (AR) as the ratio of the pressure drop to the pressure rise; sensing the humidity of the chamber after the first injection to determine a first humidity value (RHchamber); comparing the first humidity value to a pre-selected humidity value (RHsetpoint) to determine a humidity error (RHerror), wherein RHerror=RHsetpoint−RHchamber; and injecting a second quantity of water into the chamber, wherein the second quantity of water is calculated based on the absorption ratio (AR) and the humidity error (RHerror). Systems can perform the method; and the systems and methods can be employed in a sterilizer.

Abstract: A microbial indicator device for liquid disinfection comprises a first cavity, a source of biological activity fluidically coupled to the first cavity via a portion of a first fluidic path, a filter membrane positioned in a second fluidic path for a disinfectant, and a first coupling portion fluidically coupled to the source of biologically activity via the second fluidic path. The filter membrane has a first side and a second side, wherein the first side is in fluid communication with the first fluidic path. The filter membrane has a pore size sufficient to retain at least a portion of the source of biological activity on the first side. The device further comprises a frangible container contained in the first cavity, wherein a liquid in the container is in fluid communication with the first cavity when the container is fractured.

Abstract: The disclosed sterilizer includes a humidity control system for controlling humidity. The sterilizer for sterilizing objects comprises a chamber for receiving objects to be sterilized and a humidity control system. The humidity control system comprises a water control system which can be connected to a water source for injecting a first quantity of water vapor into the chamber, a pressure sensor in fluid communication with the chamber for measuring pressure in the chamber, a humidity sensor in fluid communication, or in selective fluid communication, with the chamber for sensing a first humidity value (RHchamber) of the first quantity of water vapor in the chamber; and a controller configured to inject a second quantity of water vapor into the chamber.

Abstract: A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The BI can further include a frangible container containing a liquid and dimensioned to be positioned in the housing. The reading apparatus can be configured to detect activation of the biological sterilization indicator, for example, by detecting that the second portion is in the second position, and/or by detecting that the liquid from the frangible container is present in a specific chamber of the biological sterilization indicator. The method can include positioning the BI in the well of the reading apparatus and detecting activation, for example, by detecting one or more of the above conditions.

Abstract: Aspects of the present disclosure relate to a reading apparatus that a well formed from a portion of a housing. The well dimensioned to receive at least a portion of a sterilization indicator having spores. The reading apparatus can also have a heating element thermally coupled to a portion of the well and an excitation source to excite the substance in the sterilization indicator. The reading apparatus can have a sterilization indicator activation circuit for detecting activation of the sterilization indicator. The excitation source is positioned such that light from the excitation source is directed into the well. A color sensor can be positioned adjacent the well to receive reflected light from the sterilization indicator.
