2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes for each specific test (e.g., number of gloves tested for physical dimensions, number of animals for biocompatibility). It generally refers to the standards (e.g., ASTM D6319-19, ISO 10993 series) which inherently define sample size requirements for those tests. The data provenance is from tests conducted on the subject device, "Disposable Medical Nitrile Gloves," by Jiangsu Health-Peace Medical Technology Co. Ltd. It is retrospective in the sense that the tests were completed and reported to demonstrate compliance for premarket notification. The country of origin for the manufacturing and testing is not explicitly stated as separate from the company's address in China, but the submitting company is based in China.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This device is a medical glove, and the "ground truth" for its performance is established through standardized laboratory testing (physical, chemical, and biological tests) rather than expert interpretation of medical images or clinical outcomes. The performance is objectively measured against specified criteria in established standards like ASTM and ISO.
4. Adjudication Method for the Test Set
Not applicable. As described above, the testing involves objective measurements against predefined criteria, not subjective interpretation requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable. This type of study is relevant for diagnostic or interpretive devices where human readers (e.g., radiologists) interact with the device's output. Medical gloves are not diagnostic devices, and there is no "human reader" component in their performance evaluation in this context.
6. Standalone Performance Study
Yes, standalone performance studies were done. The "PERFORMANCE DATA" section and "BIO-COMPATIBILITY DATA" section detail the results of various tests conducted on the "Disposable Medical Nitrile Gloves" alone. These tests directly measure the device's characteristics against the specified acceptance criteria of recognized standards without human intervention in the loop for assessment.
7. Type of Ground Truth Used
The ground truth used for these tests is defined by established International Standards and Specifications. Specifically:
- ASTM D6319-19: Standard Specification for Nitrile Examination Gloves for Medical Application.
- ASTM D5151-11: Standard Test Method for Detection of Holes in Medical Gloves.
- ASTM D6124-11: Standard Test Method for Residual Powder on Medical Gloves.
- ISO 10993-10: Biological evaluation of medical devices — Part 10: Tests for skin irritation and skin sensitization.
- ISO 10993-5: Biological evaluation of medical devices — Part 5: Tests for in vitro cytotoxicity.
- ISO 10993-11:2017: Biological evaluation of medical devices — Part 11: Tests for acute systemic toxicity.
These standards provide objective, measurable criteria that serve as the "ground truth" for the device's performance and safety.
8. Sample Size for the Training Set
Not applicable. This is a conventional medical device (physical product) and not an AI/machine learning algorithm. Therefore, there is no "training set" in the context of AI model development.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this 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.
