AI/ML Overview

The provided text is a 510(k) summary for a Surgical Face Mask and focuses on demonstrating substantial equivalence to a predicate device based on non-clinical bench testing and biocompatibility assessments, not on studies involving AI/ML models or human readers.

Therefore, I cannot extract the information required by your prompt regarding acceptance criteria and studies proving an AI/ML device's performance, as the document describes a traditional medical device (face mask).

The prompt's questions pertain to:

  1. AI/ML model acceptance criteria and performance.
  2. Sample sizes for test and training sets (implying data used for model development/validation).
  3. Expert ground truth establishment and adjudication (relevant for medical imaging AI).
  4. MRMC studies (relevant for AI-assisted human performance).
  5. Standalone AI performance.
  6. Type of ground truth (pathology, outcomes data, etc.).

None of these concepts are discussed in the provided text, which details the physical and material characteristics, intended use, and performance standards (e.g., fluid resistance, filtration efficiency, flammability, biocompatibility) of a surgical face mask.

The document explicitly states:

  • "No clinical tests were performed" (Section 9).
  • The tests mentioned are "Bench testing" and "Biocompatibility testing" of the physical mask.

To accurately answer your request, you would need a document describing the regulatory submission for an AI/ML-driven medical device.
