Intended Use

Stronghold Group Nitrile Examination Gloves, Powder Free is a disposable device intended for medical purposes that is worn on the examiner's hand or fingers to prevent contamination between patient and examiner.

Device Description

The subject device in this 510(k) Notification is Stronghold Group Nitrile Examination Glove, Powder Free. The subject device is a patient examination glove made from nitrile compound, blue color, powder free and non-sterile (Per 21 CFR 880.6250. Class I). The device meets the specifications in ASTM D6319-19 Standard Specification for Nitrile Examination Gloves for Medical Application.

AI/ML Overview

The Stronghold Group Nitrile Examination Gloves, Powder Free, device performance was evaluated through non-clinical testing to demonstrate substantial equivalence to a legally marketed predicate device (K203191).

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

The document does not explicitly state the specific sample sizes for each non-clinical test conducted for the Stronghold Group Nitrile Examination Gloves. However, tests were conducted according to established ASTM and ISO standards, which typically specify minimum sample sizes for valid results.

The data provenance is from non-clinical testing (laboratory-based testing) of the Stronghold Group Nitrile Examination Gloves. The country of origin for the data is not specified directly in the provided text, but the testing was for a device manufactured by Stronghold Group. The testing is prospective in the sense that it evaluates the performance of the manufactured device directly.


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

This information is not applicable as the evaluation involved non-clinical laboratory testing against established physical and chemical standards (ASTM, ISO), rather than a clinical study requiring expert interpretation of results or ground truth establishment by medical experts. The "ground truth" for these tests is defined by the objective measurement criteria of the standards themselves.


4. Adjudication Method for the Test Set

This information is not applicable as the evaluation involved non-clinical laboratory testing with objective pass/fail criteria from recognized standards, not a process that would require expert adjudication.


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

This information is not applicable. The device is a "Nitrile Examination Glove, Powder Free" and does not involve AI or human reader interpretation. The testing focuses on the physical and biocompatibility properties of the glove.


6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This information is not applicable, as the device is a physical medical glove and does not involve any algorithms or AI.


7. The Type of Ground Truth Used

The "ground truth" for the non-clinical tests is based on established standard specifications and methodologies from ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization). For example, for dimensions, the ground truth is the specified range in ASTM D6319-19; for cytotoxicity, it's the qualitative assessment of "non-cytotoxic" based on ISO 10993-5.


8. The Sample Size for the Training Set

This information is not applicable. The device is a physical medical glove, and its performance evaluation did not involve machine learning models that require a training set.


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

This information is not applicable for the same reasons as above (no training set for a physical device).

§ 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.
