Intended Use

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. These gloves are designed for single use only and should be disposed after use.

Device Description

The powder free nitrile examination glove is manufactured from Nitrile rubber. Inner surface 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 on the glove surface. The glove is ambidextrous, i.e., can be worn on right hand or left hand and it is a single use device.

AI/ML Overview

The provided document describes the acceptance criteria and results of a study for the "Black Nitrile Powder Free Patient Examination Glove, Non Sterile" (K212916).

Here's a breakdown of the requested information:

Biocompatibility - Primary Skin Irritation"Passes" (Predicate result), "Negligible" irritant response (Subject device)The test material did not cause an irritant response. The Primary Irritant Response Category is deemed 'Negligible'.Similar
Biocompatibility - Dermal Sensitization"Passes" (Predicate result), "No skin sensitization effect" (Subject device)The test material did not produce a skin sensitization effect in the guinea pigs.Similar
Biocompatibility - Cytotoxicity"Passes" (Predicate result)The test material demonstrated a cytotoxic effect under the condition of this study. Grade 2 for 6.25% & 12.5%, Grade 4 for 25%, 50% & 100%. (Note: Additional test i.e. Acute Systemic Toxicity was tested, indicating a deviation from the predicate's implied acceptance but mitigated by further testing)Different (But additional test performed)
Biocompatibility - Acute Systemic ToxicityNot Applicable (Predicate result)The test item did not induce any systemic toxicity in Swiss albino mice.Different

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Physical Properties: The document doesn't explicitly state the sample size for individual physical properties tests, but generally refers to conforming to ASTM D412.
  • Watertight: The sample size for the watertight test was 315 pieces from a batch size of 150,001 to 500,000.
  • Dimension: The document doesn't specify a sample size for dimensional measurements per glove size, but mentions measurement as per ASTM D6319.
  • Residual Powder: The sample size for residual powder was 5 pieces.
  • Biocompatibility: The sample size for biocompatibility tests is not explicitly stated in the provided text for each specific test, but they generally follow ISO and CPSC standards, which would define appropriate sample sizes for these types of biological evaluations. For Dermal Sensitization, "guinea pigs" are mentioned, and for Acute Systemic Toxicity, "Swiss albino mice" are mentioned, implying animal testing was conducted.

The data provenance is not explicitly stated as "retrospective" or "prospective." However, given that this is a 510(k) submission for a new device claiming substantial equivalence to a predicate, the tests are conducted on the subject device (K212916) in order to demonstrate its performance. The manufacturer, Rimba Glove Sdn Bhd, is located in Perak, Malaysia. The testing would have been conducted to support this submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This device is a patient examination glove, a non-AI/software medical device. Therefore, the concept of "ground truth established by experts" in the context of diagnostic interpretation (like in imaging AI) is not applicable here. The "ground truth" for the performance tests (e.g., tensile strength, watertightness, dimensions, powder content, biocompatibility) is established by adherence to recognized international and national standards (ASTM, ISO), and the results are quantifiable measurements or observed biological responses as determined by standard laboratory practices.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This is not a diagnostic device involving human interpretation that would require adjudication. The test methods are objective, standardized laboratory measurements and biological assays.

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 a physical medical device (examination glove) and does not involve human readers, AI, or diagnostic interpretation.

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

Not applicable. This is a physical medical device and does not involve algorithms or AI.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for this device's performance is based on:

  • Standardized Test Methods: Adherence to established industry standards like ASTM (e.g., ASTM D412, D5151, D3767, D6124, D6319) and ISO (e.g., ISO 10993 for biocompatibility).
  • Quantifiable Measurements: Physical properties (tensile strength, elongation, dimensions, powder residue) are measured directly.
  • Biological Responses: Biocompatibility tests (skin irritation, sensitization, cytotoxicity, systemic toxicity) are assessed based on scientific protocols for animal and in vitro tests, adhering to ISO 10993 and CPSC guidelines.

8. The sample size for the training set

Not applicable. This is a physical medical device and does not involve AI or machine learning models that require a training set.

9. How the ground truth for the training set was established

Not applicable. As there is no training set for an AI model, no ground truth was established for it.

9.0 Conclusion

The conclusion drawn from the non-clinical tests demonstrate that the subject Black Nitrile Powder Free Patient Examination Glove, Non-Sterile is as safe, as effective, and performs as well as or better than the legally marketed predicate devices K190942.

§ 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.
