摘要:
A chemical vapor sterilization process is enhanced by controlling the temperature of a diffusion path between a vaporizer and a sterilization chamber so as to condense and then re-vaporize at least a portion of the vapor.
摘要:
A sterilization system includes a sterilization chamber, a vacuum pump associated with the sterilization chamber, a vaporizer in association with the sterilization chamber, a sterilant distillation system associated with the chamber, a source of sterilant solution associated with the vaporizer and with the sterilant distillation system, and a control system which has programmed therein a first cycle in which the sterilant is admitted to the sterilization chamber at a first concentration, and a second cycle in which sterilant is concentrated in the sterilant distillation system to a second concentration, higher than the first concentration and from there admitted into the sterilization chamber and wherein the first and second cycles are selectable.
摘要:
A chemical vapor sterilization process is enhanced by concentrating a germicide via condensation and re-vaporization thereof, exploiting the difference between the vapor pressures of the germicide and its solvent to extract some of the solvent during the condensation process. A heat pump coupled with the condensation surface enhances the speed and efficiency of condensing and revaporizing the germicide.

摘要:
A method of sterilizing an article includes placing the article into a chamber containing an inner atmosphere and exhausting the inner atmosphere to lower pressure in the chamber. Hydrogen peroxide vapor is present in the chamber during at least a portion of the step of exhausting the inner atmosphere. Exhaustion of the inner atmosphere is terminated and additional hydrogen peroxide is admitted into the chamber. Hydrogen peroxide vapor contacts the article for a sufficient period to effect sterilization of the article.
摘要:
A sterilization container holds instruments during a sterilization process. It has en enclosure with an opening into the enclosure. A self-closing mechanism at the opening keeps the opening closed when not attached to a sterilant delivery source.
摘要:
A sterilization system employs a mist of chemical sterilant to sterilize devices such as medical instruments. A partial vacuum enhances dispersion of the mist into a sterilization chamber.
摘要:
A method of reducing the concentration of disinfectant in an environment having a concentration of disinfectant of about 500 ppm or less for a period of time to a lower concentration is disclosed. The method comprises the steps of dehumidifying the environment for the period of time to remove disinfectant, and humidifying the environment with moisture during the period of time to maintain a difference between a lower relative humidity and an upper relative humidity of the environment ranging from about 20 to 50%. A system for decontaminating an environment is also disclosed, comprising a source of disinfectant, a source of moisture, one or more spray generators, and a dehumidifier. A method of decontaminating an environment or enclosure is disclosed, comprising the steps of introducing disinfectant, maintaining liquid disinfectant on surfaces, and dehumidifying the environment to increase the disinfectant concentration is also disclosed.
