    Device Description

    The Disposable Medical Nitrile Examination Gloves are manufactured to meet the all current specifications listed under the ASTM Specification D6319 - 19, Standard Specification for Nitrile Examination Gloves for Medical Application. Disposable Medical Nitrile Examination Gloves are mainly composed of nitrile latex. It is mainly suitable for hand protection during medical examination. These gloves are powder free. The proposed device(s) are orange color and sold non-sterile and are intended to be single-use, disposable devices.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification for Disposable Medical Nitrile Examination Gloves. This type of medical device falls under Class I, reserved, and is a non-AI/ML device. Therefore, the detailed acceptance criteria and study design elements typically associated with AI/ML device performance (such as sample size for test/training sets, expert consensus, MRMC studies, etc.) are not applicable in this context.

    The document focuses on demonstrating substantial equivalence to a predicate device (K222498) through a series of bench tests and biocompatibility tests, primarily based on established ASTM and ISO standards for medical gloves.

    Here's how the information provided relates to the closest equivalent of "acceptance criteria" and "proof" for this specific device:

    1. Table of Acceptance Criteria and Reported Device Performance

    For this medical device, the "acceptance criteria" are the performance requirements set forth by relevant industry standards (ASTM, ISO). The "reported device performance" is the result of the bench tests demonstrating compliance with these standards.

    Acceptance Criterion (Standard)Reported Device Performance
    Physical Dimensions (ASTM D6319-19 Table 2): Conformity to specified length, width, and thickness ranges.The subject device complies with the dimension requirements prescribed in ASTM D6319-19.
    Physical Property Characteristics (ASTM D6319-19 Table 3, before and after accelerated aging): Minimum Tensile Strength and Ultimate Elongation.Before and after accelerated aging, the subject device complies with the physical requirements specified in ASTM D6319-19 Table 3.
    Freedom From Holes (ASTM D5151-06): No water leakage.No water leakage is inspected. The subject device complies with the requirements specified in ASTM D5151.
    Residual Powder (ASTM D6124-06, R2017): Less than 2 mg per glove.Residual Powder less than 2 mg per glove. The subject device complies with the requirements specified in ASTM D6124.
    Acute Systemic Toxicity (ISO 10993-11): No evidence of systemic toxicity from the extract.The test article has no potential acute system toxicity on ICR mice in the extraction method.
    Skin Irritation (ISO 10993-23: 2021): No skin irritation.Under the experimental conditions, the test article has no skin irritation on rabbits.
    Skin Sensitization (ISO 10993-10: 2021): No evidence of delayed dermal contact sensitization.The test article showed no evidence of causing delayed dermal contact sensitization in the guinea pig.

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

    • Sample Size: Not explicitly stated as a single number (e.g., N=X gloves). The testing is generally done on samples taken from production lots to ensure consistency. The specific sample sizes for each test are typically defined within the respective ASTM/ISO standards (e.g., AQL for freedom from holes).
    • Data Provenance: The device manufacturer is Hebei Titans Hongsen Medical Technology Co., Ltd. in China. The tests were performed to demonstrate compliance with international standards (ASTM, ISO). The data is generated through prospective bench testing and biological evaluation in a controlled laboratory environment.

    3. Number of Experts Used to Establish Ground Truth and Qualifications

    • Not Applicable: For this Class I device, the "ground truth" is defined by the objective, quantifiable parameters and pass/fail criteria established in the ASTM and ISO standards for glove performance and biocompatibility. There is no need for human expert consensus on subjective interpretations, as would be the case for image-based diagnostic AI. The tests are conducted by trained technicians in accredited labs according to standardized protocols.

    4. Adjudication Method for the Test Set

    • Not Applicable: As the "ground truth" is based on objective measurements and predefined standard thresholds, there is no need for an adjudication method by multiple human readers. Test results are either within the acceptable range or not.

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

    • No: MRMC studies are relevant for evaluating the impact of AI on human reader performance, typically in diagnostic imaging. This is a non-AI/ML medical glove, so such a study is not applicable.

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

    • Yes (in concept, but not an "algorithm"): The "standalone performance" for this device refers to its ability to meet the physical and biological requirements of the standards independently, without human interaction during "use" in a diagnostic or interpretive sense. The bench tests and biocompatibility tests effectively demonstrate this "standalone" performance against defined metrics.

    7. The Type of Ground Truth Used

    • Standard-based Physical and Chemical Properties / Biological Reactions: The ground truth is established by the specified acceptance criteria within the referenced ASTM (e.g., D6319-19 for physical properties, D5151-06 for holes, D6124-06 for residual powder) and ISO standards (e.g., ISO 10993-10 for sensitization, 10993-11 for systemic toxicity, 10993-23 for irritation) for medical examination gloves. These are objective, measurable physical properties and biological responses.

    8. The Sample Size for the Training Set

    • Not Applicable: This is not an AI/ML device, so there is no "training set" in the context of machine learning.

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

    • Not Applicable: No training set exists for this type of device.

    In summary, for medical gloves, the regulatory acceptance and "proof" of performance revolve around rigorous non-clinical bench testing and biocompatibility assessments against established international standards, rather than clinical studies or AI/ML specific performance metrics.

    Differences noted and addressed:

    • Length (Analysis 1): The proposed device has a different length than the predicate, but test results according to ASTM 5250 showed it meets standard requirements.
    • Colorant (Analysis 2): The proposed device is clear/non-colored, while one predicate is white, blue, or yellow. The submission argues that color difference does not affect safety and effectiveness, supported by biocompatibility testing (ISO 10993-5 and ISO 10993-10).
    • Ultimate Elongation (Analysis 3): The proposed device has a different ultimate elongation value than the predicate, but test results according to ASTM 5250 showed it meets standard requirements.

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

    • Sample Size: The document does not explicitly state the sample size for each specific test (e.g., number of gloves tested for tensile strength, freedom from holes, etc.). However, it refers to standards such as ISO 2859-1:1999 ("Sampling Procedures for Inspection by Attributes - Part I: Sampling Plans Indexed by Acceptable Quality Level (AQL) for Lot-by-Lot Inspection"), which would dictate the appropriate sample sizes for quality control testing based on lot size and AQL levels. For example, for "Freedom from Holes," an AQL of 1.5 is specified, which implies a specific sampling plan from ISO 2859-1.
    • Data Provenance: The tests were conducted by the "HEBEI TITANS HONGSEN MEDICAL TECHNOLOGY CO., LTD." in China, as indicated by the sponsor's identification. These are non-clinical (bench) tests supporting the device's conformance to established industry standards. The data is thus generated internally by the manufacturer for the purpose of this submission.
    • Retrospective or Prospective: These are laboratory/bench tests that are inherently "prospective" in the sense that they are performed on manufactured product samples to demonstrate compliance with specifications.

    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 device submission. The "ground truth" for medical gloves is established by predefined engineering specifications and performance criteria codified in international standards (e.g., ASTM D5250, ISO 10993 series). The tests are evaluated against these objective numerical or qualitative criteria, not by expert consensus in a clinical context.

    4. Adjudication method for the test set:

    Not applicable. This device is evaluated against objective technical standards (ASTM, ISO). There is no "adjudication" of expert opinions for a test set in this context.

    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 submission is for single-use medical examination gloves, which are not AI-enabled devices and do not involve human readers interpreting diagnostic images.

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

    Not applicable. This is not an AI algorithm. The device's performance is standalone in the sense that it meets physical and biocompatibility specifications on its own, without requiring human interpretation for its intended function.

    7. The type of ground truth used:

    The "ground truth" for this device's performance is defined by the objective, measurable parameters and criteria stipulated in the referenced international standards:

    • ASTM D6124 (Residual Powder)
    • ASTM D5151 (Detection of Holes)
    • ASTM D5250 (Poly(vinyl chloride) Gloves for Medical Application)
    • ISO 10993-10 (Irritation and Skin Sensitization)
    • ISO 10993-5 (In Vitro Cytotoxicity)
    • ISO 2859-1 (Sampling Procedures)

    These standards specify the methods for testing and the acceptable limits or qualities (e.g., minimum tensile strength, maximum powder content, AQL for freedom from holes, non-irritant/non-sensitizer for biocompatibility).

    8. The sample size for the training set:

    Not applicable. This is not a machine learning or AI device that requires a training set.

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

    Not applicable. This is not a machine learning or AI device.

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

    The document does not explicitly state the exact sample size for each specific test. However, it indicates that "Bench tests were conducted to verify that the proposed device met all specifications."

    • Sample Size: Not explicitly stated as a numerical value for each test. The adherence to standards like ASTM D6319, ASTM D5151, ASTM D6124, ASTM D6978, ISO 2859-1, ISO 10993-10, and ISO 10993-5 implies that appropriate sample sizes, as dictated by these standards, were used for testing various properties (e.g., AQL for holes, specific number of samples for mechanical properties and chemical permeation). ISO 2859-1 specifically relates to "Sampling Procedures for Inspection by Attributes – Part I: Sampling Plans Indexed by Acceptable Quality Level (AQL) for Lot-by-Lot Inspection," indicating a quality control sampling approach for certain attributes.
    • Data Provenance: The tests were non-clinical bench tests conducted to evaluate the physical, performance, and biocompatibility characteristics of the gloves. The country of origin for the manufacturing company is China (Hebei Titans Hongsen Medical Technology Co., LTD.).
