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

The document does not explicitly state the sample sizes used for testing each specific characteristic (e.g., number of gloves tested for tensile strength or pinholes). However, the testing is based on meeting ASTM standards (D5250-06, D5151-06, D6124-06) and ISO 10993-10. These standards typically prescribe sampling plans and methodologies.

The provenance of the data is not directly stated as "retrospective" or "prospective". However, given that this is a 510(k) submission for a new device claiming substantial equivalence to an existing one, the tests would have been performed by the manufacturer, Yongfa Glove Co., Ltd., which is located in China.

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

This information is not provided in the document. For medical gloves, "ground truth" is typically established by recognized national/international standards and testing protocols, rather than expert consensus on individual cases.

4. Adjudication Method for the Test Set

This concept (e.g., 2+1, 3+1) is not applicable to the type of device and testing described. Adjudication methods are typically used in clinical studies where human interpretation of medical images or patient conditions needs to be resolved among multiple experts. For gloves, the assessment is based on objective measurements against predefined standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices where human reader performance (with and without aid) is evaluated. This document concerns the physical and biological properties of patient examination gloves.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Not applicable. This device is a physical medical glove, not an algorithm or AI software. Therefore, there is no "standalone" algorithm performance to evaluate.

7. Type of Ground Truth Used

The ground truth used for evaluating the device is based on established industry standards and regulatory requirements:

  • ASTM Standard D5250-06 (Reaffirmation 2011): Standard Specification for Vinyl Patient Examination Gloves.
  • ASTM Standard D5151-06 (Reapproved 2011): Standard Test Method for Detection of Holes in Medical Gloves.
  • ASTM Standard D6124-06 (Reaffirmation 2011): Standard Test Method for Residual Powder on Medical Gloves.
  • ISO 10993-10 Third Edition 2010-08-01: Biological evaluation of medical devices - Part 10: Tests for irritation and skin sensitization (for biocompatibility).
  • 21 CFR 800.20: Subpart B - Performance Standards and Requirements for Medical Devices; General.

These standards define the measurable physical properties and acceptable limits for performance characteristics of the gloves.

8. Sample Size for the Training Set

Not applicable. This device does not involve machine learning or AI algorithms requiring a training set.

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

Not applicable. As there is no training set for this device type, this question is not relevant.

§ 880.6250 Non-powdered patient examination glove.

(a)
Identification. A non-powdered patient examination glove is a disposable device intended for medical purposes that is worn on the examiner's hand or finger to prevent contamination between patient and examiner. A non-powdered patient examination glove does not incorporate powder for purposes other than manufacturing. The final finished glove includes only residual powder from manufacturing.(b)
Classification. Class I (general controls). The device, when it is a finger cot, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 880.9.
