The Manzi Cleaner, when used in accordance with its labeling and the Manzi Detergent MD10, is for the cleaning of bronchoscopes in a health care setting by health care workers.
The Manzi Cleaner System consists of a Manzi Cleaner and a proprietary Manzi Detergent, MD10. The Manzi Cleaner is a self-contained stand-alone system of hardware and software designed to clean bronchoscopes using the MD10 detergent and a patented push-pull agitation system. The push-pull agitation system effectively scrubs the interior and exterior surfaces of the bronchoscope without the use of special connectors. The scope is placed in a processing chamber where it is exposed to a push-pull agitation cleaning cycle followed by two hot water rinses. The hardware for the Manzi Cleaner consists of a stainless steel processing chamber, a push-pull agitation pump, and a variety of components that are mounted in a movable covered frame. The cleaner system utilizes accessories such as disposable water filters. reusable bronchoscope trays, and printer paper. MD10 is a low foaming anionic chemical detergent packaged in custom containers for attachment to the Manzi Cleaner. The detergent is automatically diluted to a use dilution of 2.0% detergent concentration. MD10 is intended to be used exclusively with the Manzi Cleaner.
The provided text describes the Manzi Cleaner System, a device for cleaning bronchoscopes, and details the nonclinical tests conducted to demonstrate its performance and substantial equivalence to a predicate device.

Study Information
-
Sample size used for the test set and the data provenance:
- The document does not explicitly state the sample sizes (number of bronchoscopes, number of tests, replicates per test, etc.) used for any of the nonclinical tests.
- The provenance of the data (country of origin, retrospective/prospective) is not mentioned. These appear to be laboratory-based validation studies.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- The document describes nonclinical tests of the device's cleaning efficacy and safety performance (e.g., microbial load reduction, protein reduction, electrical safety). These types of tests typically rely on objective measurements and established laboratory protocols rather than human expert opinion for "ground truth." Therefore, the concept of "experts establishing ground truth" in the clinical sense does not directly apply here. The tests were performed by "Langford IC Systems, Inc." or their contracted labs.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. The nonclinical tests described involve objective measurements against predefined standards (e.g., spore log reduction, µg/cm² protein) rather than subjective assessments requiring adjudication.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No. This document describes the validation of a device cleaner (Manzi Cleaner System), not an AI-assisted diagnostic or interpretive system. Therefore, an MRMC study comparing human readers with or without AI assistance is not relevant and was not performed.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- The Manzi Cleaner System is a mechanical and chemical cleaning device with automated processes. Its performance is inherent to its design and function. The tests described (e.g., cleaning efficacy, safety) are "standalone" in the sense that they evaluate the device itself without human intervention in the cleaning process once initiated. However, it's not an algorithm in the sense of an AI or diagnostic software.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the microbial load reduction, the ground truth was based on quantitative laboratory measurements of microbial reduction (spore log reduction) from a known initial contamination level.
- For the protein loading reduction, the ground truth was based on quantitative laboratory measurements of remaining protein levels after cleaning, referenced against a standard (AAMI TIR30: 2003).
- For other tests (e.g., electrical safety, electromagnetic compatibility), the ground truth is established by adherence to recognized national and international standards and specifications.
- For "Cleaning Efficacy - Scope Ninhydrin" and "Cleaning Efficacy – Surrogate Ninhydrin", the ground truth is based on the chemical detection of residues as per the referenced EU standards.
-
The sample size for the training set:
- Not applicable. This is a medical device cleaning system, not a machine learning model that requires a training set. The "software documentation" mentioned refers to the operational software of the device itself, not an AI model.
-
How the ground truth for the training set was established:
- Not applicable, as no training set was used for an AI model.
