Powder-Free Vinyl Patient Examination Gloves, Clear (Non-colored) is a non-sterile 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, Clear (Non-colored) that meets all of the requirements of ASTM standard D 5250-06(Reaffirmation 2011).
How the device functions: PVC films form a barrier to body fluids and bloodborne Pathogens
Scientific concepts that form the basis for the device: The PVC rubber is water tight under normal conditions of use. It's tensile properties cause it to conform to the hand, allowing movements necessary for a medical procedure.
Physical and performance characteristics such as design, materials and physical properties: PVC gloves are known to create a barrier to bloodborne pathogens and body fluids. ASTM conforming tensile properties create a glove that is strong and flexible. The glove is manufactured in accordance with the requirements of ASTM D5250 and ASTM D5151 requirements.
The provided document describes a 510(k) premarket notification for "Powder Free Vinyl Patient Examination Gloves, Clear (Non-colored)." The submission aims to demonstrate substantial equivalence to a predicate device already on the market (K120968).

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific sample sizes for each test mentioned (e.g., for dimensions, tensile strength, pinholes, residual powder, or biocompatibility). It references ASTM standards (D5250-06, D5151-06, D6124-06) and ISO 10993-10, which would dictate the required sample sizes for such tests.
The data provenance is not explicitly stated. However, given that the submitter is "Shuntong Glove Co., Ltd." from China, it is highly likely that the testing and data generation occurred in China. The study is retrospective in the sense that the results are presented as already obtained data to demonstrate compliance with existing standards.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
This information is not applicable to the type of device and tests conducted. The "ground truth" for glove performance is established by standardized test methods and quantitative measurements against defined criteria in ASTM and ISO standards, not by expert consensus on qualitative data.
4. Adjudication Method for the Test Set
Not applicable. As described above, performance is measured against objective standards, not through adjudication of subjective assessments.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, and its effect size
No MRMC comparative effectiveness study was done. This type of study is relevant for diagnostic devices where human readers interpret medical images or data. For examination gloves, the demonstration of effectiveness primarily relies on physical and mechanical properties, not human interpretation. The study is a comparison of product specifications and performance to established industry standards and a predicate device.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. Examination gloves are physical devices, not algorithms. The performance evaluation focuses on the inherent characteristics of the glove material and manufacturing quality.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance is based on objective, quantitative measurements against established engineering and material science standards (ASTM and ISO standards). For example:
- Physical dimensions (length, width, thickness) are measured directly.
- Physical properties (elongation, tensile strength) are determined through mechanical testing.
- Freedom from pinholes is assessed using a water leak test specified in ASTM D5151-06.
- Residual powder is measured gravimetrically as per ASTM D6124-06.
- Biocompatibility (skin irritation and sensitization) is assessed via standardized in-vivo testing as per ISO 10993-10.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/machine learning device. There is no "training set" in the context of device performance evaluation for examination gloves.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this type of 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.
