A nitrile patient examination glove is a disposable device made of nitrile rubber intended for medical purposes that is worn on the examiner's hand or finger to prevent contamination between patient and examiner
Blue Nitrile Powder-Free Patient Examination Glove, Non-Sterile is manufactured from nitrile rubber. Innersurface of gloves undergoes surface treatment process to produce a smooth surface that assists the user in donning the gloves without using any lubricant such as powder or silicone on the glove surface. The glove is ambidextrous, i.e., can be worn on right or left hand.
Based on the provided document, the device in question is a Blue Nitrile Powder-Free Patient Examination Glove, Non-Sterile. This is not a medical imaging AI device or a diagnostic AI device. The document is a 510(k) Premarket Notification summary for a medical glove, which is a physical device, and the testing conducted is for physical and chemical properties, not algorithmic performance.
Therefore, the requested information, which pertains to the acceptance criteria and study designs for AI/ML device performance (e.g., sample size for test set, expert ground truth, MRMC studies, standalone performance, training set details), is not applicable to this document.
The document describes non-clinical testing for the glove, focusing on properties like tensile strength, elongation, dimensions, watertight integrity, residual powder, and biocompatibility.
However, I can extract and present the acceptance criteria and performance data as per the document's content, formatted as a table, making it clear that this applies to a physical device and not an AI/ML system.
Acceptance Criteria and Device Performance for Blue Nitrile Powder-Free Patient Examination Glove, Non-Sterile (K222720)

A 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.
Blue Nitrile Powder Free Patient Examination Glove, Non-Sterile meet all requirements of ASTM standard D6319 and FDA 21 CFR 880.6250. The powder free nitrile examination glove is manufactured from synthetic rubber latex. Inner surface of gloves undergoes surface treatment process to produce a smooth surface that assists the user in donning the gloves with ease without using any lubricant such as powder on the glove surface. The glove is ambidextrous, i.e., can be worn on right hand or left hand.
This document is a 510(k) premarket notification for a disposable patient examination glove. This type of device does not typically involve AI components or complex clinical studies for its clearance. Therefore, a significant portion of the requested information, particularly regarding AI development, ground truth establishment, expert consensus, and MRMC studies, is not applicable to this document.
Here's the information that can be extracted from the provided text, aligning with the categories requested:
