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 system and methods for sterilizing and drying contaminated articles, particularly medical articles, and more particularly the hollow internal areas of medical instruments or lumens of medical endoscopes. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power connected to the plasma generator applies an electrode energy density between the electrode and the shield. A source of a sterilizing gas precursor provides a flow of the sterilizing gas precursor through the plasma generator to generate a plasma, thereby forming a sterilizing gas including acidic and/or oxidizing species. The contaminated article is exposed to the sterilizing gas for a time sufficient to achieve a desired degree of sterilization. A turbulent flow of a drying gas is used to dry the contaminated article alternately with the exposure of the contaminated article to the sterilizing gas.
