Abstract: The present disclosure relates to an article for detecting a disinfectant via visual feedback. The article have a first substrate with a first major surface and opposite ends. The article also comprises a process indicator disposed on at least a portion of the first major surface. The process indicator reacts with at least one liquid disinfectant selected from the group consisting of glutaraldehyde, ortho-phthalaldehyde, hydrogen peroxide, peroxyacetic acid, and combinations thereof. The process indicator can be formed from a synthetic amine-containing polymer derived from polyethylenimine (PEI). The article can have a flow channel that is formed by a portion of the process indicator and that extends between the opposite ends. The disclosure also relates to a kit containing the article as well as a method of using the article in a disinfection process. The article is used to diagnose issues in an automated endoscope reprocessors (AERs).

Abstract: The present disclosure provides a monitoring device comprising a test composition, a test element comprising a test portion to which the test composition is releasably adhered, a detection reagent, and a container comprising a first end with an opening and a second end opposite the first end. The test composition comprises a predetermined quantity of tracer analyte. The container is configured to receive the test portion and configured to be operationally coupled to an analytical instrument. The tracer analyte and the detection reagent each are capable of participating in one or more chemical reaction that results in the formation of a detectable product. A method of using the monitoring device to assess the efficacy of a washing process is also provided.

Abstract: A method of disinfecting a medical device comprises three steps. First, a disinfectant is contacted with a process indicator and the medical device. The disinfectant comprises at least one aldehyde. The process indicator contains a synthetic amine-containing compound disposed on a substrate. The synthetic amine-containing compound comprises at least one of primary amino groups or secondary amino groups, and is reactive with the disinfectant to form at least one adduct. The synthetic amine-containing compound and the medical device are in fluid communication through the disinfectant. A predetermined disinfectant exposure criterion exists for contacting the disinfectant with the medical device. Second, the process indicator is spectrally observed and at least one parameter is obtained therefrom that is predictive of the predetermined disinfectant exposure criterion. The third step is determining that the predetermined disinfectant exposure criterion has been achieved.

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: Post-steam sterilization wet pack indicators are described. The indicators generally comprise a moisture-impermeable layer having a first surface and a moisture-indicating layer comprising a reversible colorimetric steam-sterilization-compatible moisture-indicating medium. The moisture-indicating layer is disposed on or near the first surface of the moisture-impermeable layer. The area of the moisture-indicating layer is dimensionally smaller than the moisture-impermeable layer such that the edges of the moisture-impermeable layer extend beyond the edges of the moisture-indicating layer. Articles and packages comprising wet pack indicators are also described.
