    Study Details (Applicable to Face Mask Device)

    Given that the device is a medical face mask, the "study" primarily consists of non-clinical, laboratory-based performance and biocompatibility testing, not clinical trials or AI performance evaluations as would be done for software.

    1. Sample size used for the test set and the data provenance:

      • Sample Size: Not explicitly stated in terms of number of masks or test replicates for each test, but standard test methodologies (e.g., ASTM F1862/F1862M-24, ASTM F2101-23) typically specify a minimum number of samples. The results are given for specific "lots" (e.g., Yellow mask (Level 1), White mask (Level 1), Blue mask (Level 1, 2, 3)), implying that multiple samples from these production lots were tested.
      • Data Provenance: Not explicitly stated. The manufacturer is Winner Medical Co., Ltd. from Shenzhen, China. This indicates the testing was likely conducted in China or by labs accredited to perform these standards. The tests are "Non clinical tests," meaning they are laboratory experiments rather than human subject or retrospective studies.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • Not Applicable. For this type of device (medical mask), "ground truth" is established by adherence to validated, objective, and standardized laboratory test methodologies and measurements, not by expert human interpretation (like in imaging for AI). The tests measure physical and biological properties directly.
    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • Not Applicable. Adjudication methods are relevant for human interpretation tasks (e.g., reading medical images) where there can be inter-reader variability. These are objective, quantitative laboratory tests.
    4. 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 (mask), not an AI-powered diagnostic tool. MRMC studies are used to assess the performance of AI systems in combination with human readers.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Not Applicable. This is a physical medical device (mask), not an algorithm.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • Objective Laboratory Measurements/Standards. The "ground truth" for this device is based on the objective measurements obtained through the specified ASTM, EN, CFR, and ISO standards (e.g., bacterial filtration efficiency percentage, differential pressure values, absence of penetration by synthetic blood, flammability class, cellular toxicity grading, sensitization response). These are empirical, quantitative, and qualitative results from standardized test protocols.
    7. The sample size for the training set:

      • Not Applicable. This is a physical device being tested against performance standards, not an AI/ML algorithm that requires a "training set."
    8. How the ground truth for the training set was established:

      • Not Applicable. As above, no training set for an algorithm is involved.

These are objective, measurable physical properties and biocompatibility assessments.
    7. The sample size for the training set:

      • Not applicable. This is not an AI/software device and therefore does not involve training sets.
    8. How the ground truth for the training set was established:

      • Not applicable. No training set is involved.

    Summary of the Study:

    The "study" referenced in this document is a series of non-clinical laboratory tests to demonstrate that the Fluidshield® 3 Surgical and Procedure Masks meet established performance standards for medical face masks, specifically ASTM F2100 Level 3.

    AI/ML Overview

    This document is a 510(k) summary for a Surgical Face Mask. It details the non-clinical testing performed to demonstrate substantial equivalence to a predicate device.

    Here's an analysis of the acceptance criteria and the study that proves the device meets them:

    1. Table of Acceptance Criteria and Reported Device Performance

    ItemAcceptance Criteria (ASTM F2100-23 Level 3)Reported Performance
    Performance Testing
    Bacterial filtration efficiency (BFE) (%)≥9899.7%-99.9% (Pass)

    Biocompatibility Testing
    Cytotoxicity (ISO 10993-5)Viability < 70%, it has a cytotoxic potential. (Acceptance if no cytotoxic potential)Tie on: 91.0%; Ear loops: 70.5% (No potential toxicity)
    Irritation (ISO 10993-23)Primary Irritation-Index ≤ 2.0 (Response category Negligible)Primary irritation indexes of both polar and non-polar test groups were 0. (No skin irritation)
    Sensitization (ISO 10993-10)Provided grades less than 1, otherwise sensitization. (Acceptance if no sensitization)Skin sensitization rates of both polar and non-polar extract groups were 0%. (No sensitization)

    2. Sample size used for the test set and the data provenance

    The document does not specify the exact sample sizes used for each individual performance test (BFE, differential pressure, PFE). However, for Resistance to penetration by synthetic blood and Flame spread, it states that 32 test articles were used.

    The data provenance is not explicitly stated in terms of country of origin or retrospective/prospective. Given this is a 510(k) submission for a Chinese manufacturer (Xiantao Daoqi Plastic Co., Ltd.) and tests are cited against international (ISO) and US (ASTM) standards, the testing was likely conducted in laboratories, possibly in China or other accredited facilities. The nature of these tests (bench testing) implies they are prospective assessments of product samples.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    This information is not applicable to this type of submission. The ground truth for these medical device tests (surgical face mask performance and biocompatibility) is established by adherence to recognized international and national standards (ASTM, ISO). These standards define specific methodologies and acceptance criteria. No human experts are involved in establishing "ground truth" in the way they would for a diagnostic AI study. The "experts" are the technicians performing the standardized tests and interpreting the results against the defined criteria.

    4. Adjudication method for the test set

    This information is not applicable. The tests are objective measurements against predefined criteria in recognized standards. There is no adjudication process involving multiple human observers or adjudicators for these types of physical and chemical tests.

    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

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging devices or AI-powered clinical decision support systems, not for a physical device like a surgical face mask.

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

    No, a standalone (algorithm only) performance study was not done. This is not an AI/algorithm-based device. The device is a physical surgical face mask.

    7. The type of ground truth used

    The "ground truth" for this device is established by objective measurements and assessments against recognized performance and biocompatibility standards (ASTM F2100-23, ASTM F2101-23, ASTM F1862/F1862M-17, ISO 10993-5, ISO 10993-23, ISO 10993-10). These standards define the acceptable range of physical properties and biological responses for surgical masks.

    8. The sample size for the training set

    Not applicable. This is a physical device, not an AI or machine learning model, so there is no "training set."

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

    Not applicable. As there is no training set, there is no ground truth for a training set.

    AI/ML Overview

    The provided text is an FDA 510(k) summary for PRIMED Surgical Masks and PRIMED Procedure Masks. It describes the acceptance criteria and the study that proves the device meets those criteria. However, it does not include information about a complex AI-driven medical device, a multi-reader multi-case (MRMC) study, or detailed information about ground truth establishment by experts as would be relevant for an AI/CADe system.

    Therefore, the following response will be tailored to the information available in the provided document, which pertains to a physical medical device (surgical masks) and its performance against established standards, rather than an AI/software device.

    Here's the information as extracted and interpreted from the document:


    Acceptance Criteria and Device Performance for PRIMED Surgical Masks and PRIMED Procedure Masks

    The device under review is PRIMED Surgical Masks and PRIMED Procedure Masks. The performance of these masks is evaluated against established physical and biocompatibility standards rather than a typical AI/CADe performance criteria.

    1. Table of Acceptance Criteria and the Reported Device Performance

    The acceptance criteria are derived from ASTM F2100-23 standards for medical face masks and other relevant ISO and CFR standards for biocompatibility and flammability.

    Test PerformedTest MethodAcceptance Criteria (Level 1 Masks)Acceptance Criteria (Level 3 Masks)Results (All Variants)
    Bacterial Filtration EfficiencyASTM F2101≥ 95%≥ 98%Pass
    Sub-micron Particulate FiltrationASTM F3502≥ 80%≥ 85%Pass
    Differential Pressure (Breathability)EN 14683< 5 mmH2O/cm²< 6 mmH2O/cm²Pass
    Resistance to Penetration by Synthetic BloodASTM F186280 mmHg160 mmHgPass
    Flammability16 CFR 1610Class IClass IPass
    CytotoxicityISO 10993-5Non-CytotoxicNon-CytotoxicPass
    SensitizationISO 10993-10Non-sensitizingNon-sensitizingPass
    IrritationISO 10993-23Not an irritantNot an irritantPass

    2. Sample Size Used for the Test Set and Data Provenance

    The document does not explicitly state the sample sizes used for each specific test (e.g., number of masks tested for BFE). These are typically defined by the test methodologies themselves (e.g., ASTM F2101 specifies sample sizes).
    The data provenance is from non-clinical testing performed by the manufacturer, PRIMED Medical Products Inc., which is based in Edmonton, AB, Canada. The studies are prospective in the sense that they are conducted specifically for the purpose of demonstrating device performance for regulatory submission.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    This section is not applicable as the device is a physical product (surgical masks) and not an AI or diagnostic software. Therefore, human experts are not establishing "ground truth" in terms of clinical diagnoses or interpretations of images. The "truth" is established by direct physical, chemical, and biological testing against engineering and material standards.

    4. Adjudication Method for the Test Set

    This is not applicable as there is no human interpretation or decision-making process being adjudicated. The tests involve objective measurements against predefined thresholds.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for AI/software in diagnostic imaging where human readers' performance with and without AI assistance is evaluated. This submission is for a physical medical device.

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

    This is not applicable. The device is a physical product (surgical mask), not an algorithm or software. The "performance" is the inherent physical and chemical properties of the mask.

    7. The Type of Ground Truth Used

    The "ground truth" for the performance of the surgical masks is established directly through physical, chemical, and biological laboratory testing against well-defined, objective national and international consensus standards (e.g., ASTM F2100-23, EN 14683, ISO 10993 series, 16 CFR 1610). There is no "expert consensus," "pathology," or "outcomes data" utilized to establish ground truth in the context of diagnostic accuracy for this device.

    8. The Sample Size for the Training Set

    This is not applicable. Surgical masks are physical devices, not AI or machine learning models that require training sets. The document describes performance testing of the final manufactured product.

    9. How the Ground Truth for the Training Set Was Established

    This is not applicable for the same reason as above. There is no training set for a physical device like a surgical mask.
