2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the sample sizes used for each specific test listed (e.g., number of gloves tested for length, width, etc.). However, the tests are conducted in accordance with ASTM and ISO standards, which typically specify sampling plans.
The data provenance is from non-clinical tests conducted for the SHARK GLOVES and INCONGLOVE Blue Nitrile Examination Gloves Powder Free. The manufacturer and exporter is SRIRUNGRUANG GLOBAL CO., LTD, located in Thailand. The studies are prospective as they were conducted specifically for this 510(k) submission to demonstrate substantial equivalence.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
The document does not mention the use of experts or the establishment of ground truth in the context of clinical or diagnostic studies. The tests described are non-clinical, laboratory-based physical and biocompatibility assessments of the gloves. Therefore, the concept of "ground truth" established by experts, as it would be for diagnostic accuracy studies, is not applicable here. The "ground truth" for these tests is defined by the objective measurement criteria within the specified ASTM and ISO standards.
4. Adjudication Method for the Test Set
Not applicable. As noted above, these are non-clinical laboratory tests with objective pass/fail criteria based on established standards, not studies requiring expert adjudication of 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 is not an AI-assisted diagnostic device, nor is it a study involving human readers or cases. It is a submission for patient examination gloves.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an algorithm-based device.
7. The Type of Ground Truth Used
For the non-clinical tests, the "ground truth" is based on the specified quantitative and qualitative requirements of the referenced ASTM and ISO standards, such as minimum length, tensile strength, maximum powder residue, and the absence of irritation or sensitization. For the biocompatibility tests that showed cytotoxicity but no systemic toxicity concern, the "ground truth" was established through additional testing to confirm the lack of systemic risk.
8. The Sample Size for the Training Set
Not applicable. This is a medical device (examination gloves), not a machine learning or AI model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. See point 8.
§ 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.
