Intended Use

It is intended for use as primary or secondary dressings for exuding wounds,surgical incisions, abrasions, first and second degree burns, wound packing, donor sites, catheter sites, I. V. sites and central lines. Also may be used for securement of primary dressing. The antimicrobial activity of the PHMB and benzalkonium chloride in dressing helps resist bacterial colonization within the dressing.

Device Description

The proposed devices are available in three configurations, which are Antimicrobial gauze sponge dressing. Antimicrobial super sponge dressing and Antimicrobial non-woven sponge dressing. All of them consist of (1) a dressing (base material) and (2) anti-microbial agent. For each configuration, it is available in several models, which are different in size and quantity of anti-microbial agent.

The product can achieve board spectrum antimicrobial effect within the dressing for Gram-Bacteria and Fungi. It has been shown to have 4 log bacterial reduction in vitro against includes: Staphylococcus aureus, Escherichia coli, Candida albicans, Pseudomona aeruginosa and Bacillus subtilis, Streptococcus pyogenes, Serratia marcescens, Aspergillus niger. The effective inhibition of bacteria within the dressing is 7 days.

AI/ML Overview

The provided text is a 510(k) Summary for a medical device (Antimicrobial gauze sponge dressing, Antimicrobial super sponge dressing, Antimicrobial non-woven sponge dressing). It describes a submission to the FDA seeking clearance based on substantial equivalence to a predicate device.

The document does not describe a study conducted to prove the device meets specific acceptance criteria in the way a clinical trial or algorithm performance study would. Instead, it focuses on non-clinical tests to demonstrate compliance with standards and substantial equivalence to a predicate device.

Therefore, many of the requested categories for the acceptance criteria and study that proves the device meets them cannot be answered from this document because they are not applicable to the type of submission described (a 510(k) for a dressing, not an AI/ML diagnostic device). Specifically, there is no mention of an algorithm, AI, human readers, ground truth establishment for a test set, or training set details.

However, I can extract information related to the acceptance criteria as described by standard compliance and the comparison to the predicate device.


Here's a breakdown of the information that can be extracted or deduced from the provided document, addressing the structure of your request where applicable, and indicating when information is not available:

1. A table of acceptance criteria and the reported device performance

The document does not present "acceptance criteria" in the format of a clinical performance target (e.g., sensitivity/specificity thresholds) or a statistical endpoint for a trial. Instead, the "performance" discussed is compliance with established standards and similar characteristics to a predicate device.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not applicable and not provided as there was no "test set" in the context of an algorithm or diagnostic performance study. The studies mentioned are non-clinical lab tests for material properties, sterilization, and biocompatibility. Details like sample sizes for these specific lab tests are generally found in the full test reports, which are not part of this summary document. Data provenance details are also not stated for these non-clinical tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable and not provided. There was no "ground truth" to be established by experts for a diagnostic performance test, as this device is a wound dressing and not a diagnostic AI/ML tool.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable and not provided. No adjudication method was used for a test set, as this is not a diagnostic device.

5. 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

This information is not applicable and not provided. No MRMC study was performed as this is a medical device clearance for a wound dressing, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable and not provided. There is no algorithm associated with this wound dressing device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

This information is not applicable and not provided. There was no "ground truth" established in the context of diagnostic performance. The "truth" for this device's performance comes from compliance with recognized standards (e.g., ISO, ASTM, USP) and laboratory assays for antimicrobial activity.

8. The sample size for the training set

This information is not applicable and not provided. There is no "training set" for this device, as it is not an AI/ML algorithm.

9. How the ground truth for the training set was established

This information is not applicable and not provided. There is no "training set" for this device, as it is not an AI/ML algorithm.
