More Information

K/DEN Number Not Found

No
The 510(k) summary describes a physical medical device (examination gloves) and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.

No.
The device, disposable nitrile examination gloves, is intended to prevent contamination between patient and examiner, not to provide therapy or treatment for an illness or condition.

No
The device, disposable nitrile examination gloves, is intended to prevent contamination between patient and examiner and does not perform any diagnostic function.

No

The device is a physical product (gloves) and the description focuses on material properties and physical testing, not software functionality.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to prevent contamination between patient and examiner by being worn on the hand or finger. This is a barrier function, not a diagnostic test performed in vitro (outside the body).
  • Device Description: The description is of a physical glove, not a reagent, instrument, or system used to examine specimens from the human body.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in those samples
    • Providing information for diagnosis, monitoring, or screening of diseases or conditions.
  • Performance Studies: The performance studies focus on the physical properties and biocompatibility of the glove (watertightness, dimensions, physical properties, toxicity, sensitization, irritation), which are relevant to a barrier device, not a diagnostic test.

The device is clearly described as a medical device intended for a barrier function, not an in vitro diagnostic test.

FOSHAN KANGKANG BIOTECHNOLOGY CO., LTD

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