AI/ML Overview

This is a medical device submission for a "Medical Surgical Mask" (K210813). The document describes non-clinical performance testing against established standards and a predicate device.

Here's a breakdown of the requested information:

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

TestAcceptance Criteria (Predicate Device)Reported Device Performance (Subject Device)Result
Synthetic Blood Penetration ResistanceNo penetration at 160 mmHgNo penetration at 160 mmHgPass
Particulate Filtration Efficiency (0.1 µm)>98 %>98 %Pass
Bacterial Filtration Efficiency>98 %>98 %Pass
Differential Pressure (Delta P)≤ 6.0 mmH2O/cm²≤ 6.0 mmH2O/cm²Pass
FlammabilityClass 1Class 1Pass
Cytotoxicity (ISO 10993-5)Non-cytotoxicNon-cytotoxicPass
Irritation (ISO 10993-10)Non-irritatingNon-irritatingPass
Sensitization (ISO 10993-10)Non-sensitizingNon-sensitizingPass

The acceptance criteria for the subject device are explicitly stated as meeting or exceeding the performance of the predicate device (DemeMASK Surgical Mask, K201479) and conforming to relevant standards (ASTM F1862, ASTM F2299, ASTM F2101, EN 14683:2019+AC:2019, 16 CFR 1610, ISO 10993-5, ISO 10993-10).

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

The document does not explicitly state the sample sizes used for each performance test. The data provenance is not specified, but the manufacturing company (Sichuan Pharmaceutical, Inc.) is based in China. The testing was conducted as part of a premarket notification for the FDA, making it a prospective study relative to the submission.

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 is a physical device (surgical mask), not an AI/software device. Therefore, the concept of "experts establishing ground truth" in the context of image interpretation or diagnosis is not applicable. The performance is measured objectively against established physical and biological standards using laboratory testing.

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

Not applicable for physical device performance testing. The results are obtained through standardized laboratory procedures, not expert adjudication of subjective assessments.

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

Not applicable. This is a physical medical device (surgical mask), not an AI-assisted diagnostic or therapeutic device.

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

Not applicable. This is a physical medical device.

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

For this physical device, the "ground truth" is defined by the established performance standards (e.g., ASTM F1862 for synthetic blood penetration, ASTM F2299 for particulate filtration efficiency, ISO 10993 for biocompatibility). The device's performance is measured against these objective, quantitative criteria.

8. The sample size for the training set

Not applicable. This is a physical device, and there is no "training set" in the context of machine learning.

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

Not applicable. There is no training set mentioned or implied for this physical device.
