  • Integrated chemical indicator device
    Patent number: 9726652
    Abstract: A chemical indicator device for use in detecting exposure to an oxidizing agent, such as hydrogen peroxide, comprising a substrate or support upon which is disposed a chemical indicator composition (ink) for detecting an oxidizing agent, such as hydrogen peroxide. The chemical indicator composition further comprises an indicator dye that achieves a distinct range of different color changes with clear transitions between colors, upon exposure to different doses of the oxidizing agent, thus allowing for both a qualitative and semi-quantitative assessment of exposure to the agent.
    Type: Grant
    Filed: October 10, 2014
    Date of Patent: August 8, 2017
    Assignee: STERIS, INC.
    Inventors: Stephen Michael Lacy, Neil David Tyers
