A latex surgeon's glove is a device made of natural rubber intended to be worn by operating room personnel to protect a surgical wound from contamination.
The proposed device. Latex Surgeon's Gloves Powdered is a sterilized and disposable medical glove intended to be worn by operating room personnel to protect a surgical wound from contamination. The proposed device is made of natural rubber latex, per standard ASTM D3577-096', the rubber surgical gloves classification is: "Type I - gloves compounded primarily from natural rubber latex". The proposed device is Powdered Latex Surgeon's Gloves, and variations of different size. All variations share the same color, creamy white. The proposed device is provided Gamma radiation sterilized to achieve the Sterility Assurance Level (SAL) of 10-6 and place in a sterility maintenance package to ensure a shelf life of 3 years.
The provided text describes a 510(k) premarket notification for a medical device: "TULIP Natural Rubber Latex Surgeon's Glove (Powdered)". This submission aims to demonstrate substantial equivalence to a legally marketed predicate device rather than proving novel safety and effectiveness. Therefore, the "study" described is a series of bench tests and adherence to recognized standards, not a clinical trial in the traditional sense.
Here's an analysis of the acceptance criteria and the "study" that proves the device meets them, based on your requested information categories:

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes used for each specific test (e.g., how many gloves were tested for dimensions, tensile strength, pinholes, etc.). It refers to adherence to the methodologies outlined in the referenced ASTM and ISO standards for these tests. These standards typically specify minimum sample sizes for their respective test methods.
The data provenance is not specified beyond being "bench tests" conducted by the manufacturer, Shanghai Jinxiang Latex Products Co., Ltd. The country of origin of the data would therefore be China, where the manufacturer is located. The nature of these tests (bench testing) makes them prospective in the context of generating data for the 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of information is not applicable to this submission. The "ground truth" for glove performance is established by the accepted industry standards (ASTM, ISO, and FDA regulations) themselves. The testing involves objective measurements against these predefined numerical and qualitative criteria, not subjective expert interpretation of data.
4. Adjudication Method for the Test Set
Not applicable. The tests are objective measurements against established standards, not a consensus-based adjudication process.
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/software as a medical device (SaMD) and therefore no MRMC study or AI-related comparative effectiveness was performed or required.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is a physical medical device (surgical glove), not an algorithm or software. "Standalone performance" in this context refers to the glove's physical and biological properties as measured by the bench tests, without human intervention in the performance of the device itself (only in its use).
7. The Type of Ground Truth Used
The "ground truth" used is defined by adherence to published and recognized national and international standards (ASTM and ISO) and FDA regulations (21 CFR 800.20). These standards specify acceptance criteria for various physical, chemical, and biological properties of surgical gloves. The tests performed are designed to objectively measure these properties against those established "ground truths."
8. The Sample Size for the Training Set
Not applicable. This is a physical medical device, not a machine learning algorithm that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set for this device.
§ 878.4460 Non-powdered surgeon's glove.
(a)
Identification. A non-powdered surgeon's glove is a device intended to be worn on the hands of operating room personnel to protect a surgical wound from contamination. A non-powdered surgeon's 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).
