  • Patent number: 11951223
    Abstract: A method and an apparatus are provided for cleaning, disinfecting, and/or sterilizing a device. The method comprises contacting an object with an obstructing substance such that the object is infiltrated with at least a portion of the obstructing substance. An absorptive and/or adsorptive capacity of the object is reduced by the obstructing substance. The object is contacted with a treatment agent after the capacity of the object is reduced. Infiltration of the object with the treatment agent is limited by the reduction of the capacity of the object.
    Type: Grant

  • Patent number: 11953415
    Abstract: A method and a system for determining analyte content in a fluid in a treatment apparatus. The method comprises positioning a device for treatment in a treatment apparatus. A surface of the device is contacted with a fluid. An analyte content in the fluid is determined based on an electromagnetic property of the fluid following contacting the surface of the device with the fluid. More specifically, an electromagnetic property is measured. The measuring comprises emitting electromagnetic radiation into the fluid in the treatment apparatus and detecting electromagnetic radiation from the fluid. In another aspect, a system comprising a treatment apparatus and a detector for determining the analyte content in the fluid in the treatment apparatus is provided.

  • Publication number: 20230129570
    Abstract: An indicator and method of use thereof, and indicator system and method of use thereof are provided to determine the degree of an oxidative treatment. An indicator is incorporated into the oxidative treatment. The object and the indicator are subjected to the oxidative treatment. A discoloration of the indicator occurs based on an oxidation of the polymer by a process condition of the oxidative treatment oxidizing the polymer. The discoloration of the indicator is measured against a threshold color value to determine the degree of the oxidative treatment.
