Powder free vinyl 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.

powder free vinyl patient examination gloves, white(non-colored) that meets all of the requirements of ASTM standard D 5250-0064.

The provided document describes the "Powder Free Vinyl Patient Examination Gloves, white (non-colored)" and its premarket notification (510(k)) summary. It focuses on demonstrating substantial equivalence to a predicate device rather than a comprehensive study of device performance against specific acceptance criteria using a test set. This type of submission relies on established standards and non-clinical testing.

Here's an analysis of the available information based on your requested categories:

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

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 the testing mentioned (e.g., for dimension, physical properties, pinholes, powder residual, or biocompatibility). It only indicates that the device "Meets" the respective standards. The data provenance is not specified, but the device manufacturer is ZIBO SINOCARE PLASTIC PRODUCTS CO., LTD in China. The testing would have been conducted by or for this company. This testing would be considered prospective, as it's conducted to demonstrate compliance for a new device.

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 not applicable as the device's performance is assessed against established ASTM and CFR standards, not through expert consensus on a subjective test set. The standards themselves define objective metrics. For biocompatibility, animal models (rabbits and guinea pigs) were used, not human experts to establish "ground truth" in the way one would for image interpretation, for example.

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

Not applicable. Device performance is measured directly against technical standards, not through expert adjudication of subjective results.

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 device is a disposable medical glove, not an AI-powered diagnostic or assistive technology that would involve human readers or MRMC studies.

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

This concept is not applicable to a physical medical device like a glove. The "standing alone" performance refers to the device's inherent characteristics as measured against specified standards.

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

The "ground truth" for evaluating the performance of these gloves is defined by:

• Established ASTM Standards: These provide quantitative and qualitative specifications for dimensions, physical properties (e.g., tensile strength, elongation), and powder residual.
• Regulatory Standards (21 CFR 800.20): Specifically for freedom from pinholes, which dictates an Acceptable Quality Level (AQL) for water leak testing.
• Biocompatibility Standards (ISO10993-10): These guide the animal testing for primary skin irritation and dermal sensitization. The "ground truth" for these tests is the observed biological response in the animal models according to the standard's interpretation guidelines (e.g., absence of irritation).

8. The sample size for the training set

Not applicable. There is no "training set" in the context of this device. The physical characteristics and biological safety of gloves are determined through standardized testing, not machine learning or algorithm training.

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

Not applicable, as there is no training set for this type of device.
