A patient examination glove 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.

Annuy Latex Patient Examination Glove (powdered and powder-free) is a glove made from natural rubber that covers the hand up to the wrist. It is cuffed and equally wearable on either hand, free from differentiation between the left hand and the right. It has three sizes, i.e., large, medium, and small. All variations share the same natural color, creamy white. The glove is non-sterile and is for single use only, to be discarded after each examination is performed. It acts as a barrier between the examiner and the subject being examined in order to prevent contamination between them.

Annuy Nitrile Patient Examination Glove (powdered and powder-free) is a glove made from nitrile butadiene rubber Latex that covers the hand up to the wrist. It is cuffed and equally wearable on either hand, free from differentiation between the left hand and the right. It has three sizes, i.e. large, medium, and small. All variations share the same blue color. The glove is non-sterile and is for single use only, to be discarded after each examination is performed. It acts as a barrier between the examiner and the subject being examined in order to prevent contamination between them.

The provided documents detail the acceptance criteria and performance study for four types of examination gloves: Powdered Latex, Powder-free Latex, Powdered Nitrile, and Powder-free Nitrile.

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

The document does not explicitly state the exact "sample size used for the test set" (i.e., the number of individual gloves tested for each characteristic). However, it references specific ASTM and ISO standards that govern testing procedures for these types of gloves. These standards typically define sampling plans, AQL (Acceptable Quality Level) for certain tests (like freedom from holes), or specify the number of specimens for physical property testing. For example, for "Freedom from Holes," AQL values are given (2.5 for Inspection Level I for latex, 2.5 for Inspection Level G-1 for nitrile), implying a sampling plan was followed.

The data provenance is Anhui Anyu Latex Products Co., Ltd in Bengbu, Anhui, China, as they are the manufacturer and submitter of the 510(k) premarket notification. The data appears to be from retrospective testing conducted by the manufacturer to demonstrate compliance with the referenced standards.

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

This section is not applicable as the described tests are laboratory-based, objective performance measures (e.g., dimensions, physical properties, chemical residue, biocompatibility) of physical devices (gloves) against established engineering and safety standards. They do not involve interpretation of complex data (like medical images) by human experts to establish ground truth in the way medical AI or diagnostic devices would.

4. Adjudication Method for the Test Set

This is not applicable for the same reason as point 3. The assessment criteria are derived from objective measurements against specified standards.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The document explicitly states: "Clinical data was not included in this submission." The evaluation focused entirely on technical and physical performance metrics of the gloves against recognized standards.

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

This is not applicable. The device is a patient examination glove, a physical product, not an algorithm or AI system. Therefore, the concept of a "standalone" algorithmic performance is irrelevant. The tests performed are standalone in the sense that they assess the intrinsic properties of the glove material and manufacturing.

7. The Type of Ground Truth Used

The ground truth used for performance evaluation is based on established industry standards and regulatory requirements. Specifically, these include:

• ASTM (American Society for Testing and Materials) Standards:
  • ASTM D3578-10 (Standard Specification for Rubber Examination Gloves)
  • ASTM D6319-10 (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)
  • ASTM D5712-10 (Standard Test Method for the Analysis of Aqueous Extractable Protein in Natural Rubber Products Using the Modified Lowry Method)
• ISO (International Organization for Standardization) Standard:
  • ISO 10993-10 (Biological Evaluation of Medical Devices - Part 10: Tests for Irritation and Skin Sensitization)

These standards define the acceptable ranges or thresholds for various physical, chemical, and biological properties of examination gloves.

8. The Sample Size for the Training Set

This is not applicable. The device is a physical product (medical glove), not an AI/ML model that requires a training set. The manufacturing process of the gloves would involve quality control and process monitoring, but this is distinct from training a software algorithm.

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

This is not applicable as there is no training set for a physical medical device like an examination glove.
