Device Story

Disposable nitrile examination gloves; non-sterile; worn on examiner's hand or finger. Function: physical barrier to prevent contamination between patient and examiner. Used in clinical settings by healthcare professionals. Benefit: reduces risk of cross-contamination during patient examinations.

Clinical Evidence

No clinical data. Bench testing only. Testing included biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity), watertightness (ASTM D5151-19), physical dimensions (ASTM D6319-19), and physical properties (tensile strength, elongation). All results met acceptance criteria.

Technological Characteristics

Material: Nitrile. Form factor: Disposable, non-sterile, blue, ambidextrous gloves. Sizes: S, M, L, XL. Standards: ASTM D6319-19, ASTM D6124-06, ASTM D5151-19, ISO 10993-5/10/11. No software or electronic components.

Indications for Use

Indicated for use as a non-sterile, disposable medical glove worn on the examiner's hand or finger to prevent cross-contamination between patient and examiner.

Regulatory Classification

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.

Dear Yico Xie:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

| In Vitro Cytotoxicity Test:<br>Agar diffusion Method | The purpose of the test is to<br>determine the potential cytotoxicity<br>toxicity of a mammalian cell culture<br>(mouse fibroblast L-929 cells) in<br>response to the test article. | The test sample met the requirements of the test if the biological<br>response was less than or equal to grade 2. | Under the conditions of<br>this study, the test article<br>was Slight cytotoxic and<br>was accepted in the agar<br>diffusion method. |
| Skin Sensitization Test:<br>Guinea Pig Maximization | The test was designed to evaluate<br>the potential of a test article to cause<br>skin sensitization. The test is used as<br>a procedure for screening of contact<br>allergens in guinea pigs and<br>extrapolating the results to humans,<br>but it does not establish the actual<br>risk of sensitization. | Magnusson and Kligman grades of 1 or greater in the test group<br>generally indicate sensitization, provided grades of less than 1<br>are seen in control animals.<br>If grades of 1 or greater are noted in control animals, then the<br>reactions of test animals which exceed the most severe reaction<br>in control animals are presumed to be due to sensitization.<br>If the response is equivocal, rechallenge is recommended to<br>confirm the results from the first challenge.<br>The outcome of the test is presented as the frequency of positive<br>challenge results in test and control animals. | The test article showed no<br>evidence<br>of<br>causing<br>delayed dermal<br>contact<br>sensitization in the guinea<br>pig. |
| Skin Irritation Test:<br>Extraction Method | To evaluate the potential<br>skin<br>irritation caused by test article<br>contact with the skin surface of<br>rabbits and extrapolating the results<br>to humans, but it does not establish<br>the actual risk of irritation. | When blank or negative control was used, calculate the primary<br>irritation score for the controls and subtract that score from the<br>score using the test material to obtain the primary irritation<br>score. | The test result showed that<br>the response of the test<br>article<br>extract<br>was<br>categorized as negligible<br>under the test condition. |
| Acute Systemic Toxicity Test:<br>Extraction Method | The test was designed to evaluate<br>the potential acute system toxicity<br>caused by test article contact with<br>the ICR mice and extrapolating the<br>results to humans. | Within the monitoring period (72 h), if the toxicosis response<br>of testing group is not greater than that of control group, the<br>testing sample is regarded as acceptable. In case that two or<br>more mice show the medium toxicosis symptom or die, the<br>testing sample is regarded as unacceptable. If any animals<br>treated with the sample show only slight signs of biological<br>reactivity, and not more than one animal shows gross symptoms<br>of biological reactivity or dies, repeat the testing using groups<br>of 10 animals. On the repeat test, if all 10 animals treated with<br>the sample show no scientifically meaningful biological<br>reactivity above the vehicle control animals during the<br>observation period, the sample meets the requirements of this<br>test. | The test article showed no<br>evidence of causing acute<br>system toxicity in the ICR<br>mice. |
