This document is a 510(k) summary for a Nitrile Glove Powder Free Black, classifying it as a Class I medical device. The submission aims to demonstrate substantial equivalence to a legally marketed predicate device (K171422).
Here's an analysis of the provided information regarding acceptance criteria and the supporting study:
1. Table of Acceptance Criteria & Reported Device Performance:
The document presents a "Technological Characteristic Comparison Table" (Table 1), "Device Dimensions Comparison" (Table 2), "Performance Comparison" (Table 3), and "Safety Comparison" (Table 4) where the proposed device's performance is compared against the predicate device and relevant standards. This serves as the primary method to demonstrate that the proposed device meets the acceptance criteria (substantial equivalence to the predicate and compliance with recognized standards).

2. Sample Sizes and Data Provenance (for test set, if applicable):
The document states, "Non-clinical tests were conducted to verify that the proposed device met all design specifications." However, it does not specify the sample sizes used for these non-clinical tests (e.g., how many gloves were tested for Freedom from Holes, Tensile Strength, etc.).
The data provenance is not explicitly stated as retrospective or prospective, nor does it mention a country of origin for the data, other than the submitting company being located in China. Given the nature of these tests (bench testing for physical and chemical properties), they would typically be prospective tests performed on samples of the manufactured device.
3. Number of Experts and Qualifications (for ground truth of test set):
This information is not applicable to this submission type. Ground truth in this context typically refers to clinical diagnosis or pathology readouts. For a Class I medical device like a glove, the "ground truth" is adherence to physical/chemical standards and biocompatibility tests, not expert clinical interpretation. The "experts" would be the personnel in the testing laboratories conducting the ASTM and ISO standard tests. Their qualifications are inherent in their ability to perform these accredited tests.
4. Adjudication Method (for test set):
This information is not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical studies for diagnostic accuracy, where multiple human readers interpret data, and a consensus mechanism is employed to establish ground truth or resolve discrepancies. For physical and biocompatibility testing of a medical glove, objective laboratory test results are obtained, and no such adjudication is necessary.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
An MRMC study was not done and is not relevant for this type of device. MRMC studies are typically performed for diagnostic imaging devices to assess the impact of AI on reader performance.
6. Standalone (Algorithm Only) Performance Study:
A standalone performance study was not done and is not applicable. This is a physical product (a glove), not an algorithm or AI-powered device.
7. Type of Ground Truth Used:
The "ground truth" for the device's performance is established through:
- Compliance with recognized international and national standards: ISO 10993-10, ISO 10993-5, ASTM D6124-06, ASTM D5151-06, and ASTM D6319-10. These standards define the acceptable performance characteristics for medical gloves.
- Comparison to a legally marketed predicate device (K171422): Demonstrating that the proposed device's characteristics (dimensions, physical properties, material, biocompatibility) are substantially equivalent to a device already cleared by the FDA.
8. Sample Size for the Training Set:
This information is not applicable. This device is a physical product, not an AI/ML algorithm that requires a training set.
9. How the Ground Truth for the Training Set Was Established:
This information is not applicable as there is no training set for this device.
