Intended Use

The Clickfine AutoProtect pen needle is intended for the hypodermic injection of fluids into the body when attached to an injection pen. Additionally, after withdrawal of the pen needle from the body, the attached needle safety shield will automatically cover the needle to minimize the risk of accidental needlestick.

Device Description

The Ypsomed Clickfine AutoProtect Pen Needles are sterile, non-pyrogenic, single use needles designed to be used with commercially available pen-injectors for the administration of prescribed fluids. Each needle is individually packaged in a sealed protective container with a peel tab. The pen needle is used by peeling back the peel tab and snapping the housing onto the threaded end of the pen-injector. The back end of the cannula punctures the septum of the drug reservoir in the pen-injector. The outer protective cap is then removed. When the injection is needed the needle is inserted into the chosen site. While inserting the needle into the safety shield glides into the housing enabling the needle to penetrate the skin barrier and into the subcutaneous tissue. While the safety shield glides into the housing the safety mechanism will be activated. The pen-injector delivers the medicinal product through the needle. After the injection, in order to remove the needle from the skin, the user moves the pen injector away from the skin. As the pen and needle is moved away from the skin, the safety shield glides back in its initial position, completely covering the needle, where it will remain locked. The safety shield is designed to automatically cover the needle (provide passive protection) to minimize the risk of accidental needle-stick injury. Once the Clickfine AutoProtect pen needle is in the locked mode, it can no longer be used. The red safety lock indicator tells the user that the safety lock has been activated. The needle is detached from the injection device and disposed of in accordance with local regulations. For each subsequent iniection, another disposable needle must be used.

AI/ML Overview

The provided text is a 510(k) summary for a medical device (Clickfine AutoProtect Pen Needle) and describes its safety and effectiveness based on compliance with various standards, rather than a study comparing its performance against specific acceptance criteria with quantifiable metrics. Therefore, it is not possible to fully answer your request in the format you provided, as the document does not contain the specific statistical results, sample sizes for test sets, expert qualifications, or adjudication methods typically found in a clinical study report for AI/CAD devices.

However, I can extract the information that is present and indicate where information is missing.

Here's an attempt to structure the available information, noting the missing elements:

Device: Clickfine AutoProtect Pen Needle

Description of Device: The Ypsomed Clickfine AutoProtect Pen Needle is a sterile, non-pyrogenic, single-use needle designed for use with pen-injectors to administer prescribed fluids. Its key feature is an automatic safety shield that covers the needle after withdrawal from the skin to minimize the risk of accidental needle-stick injury. Once locked, the needle cannot be reused, and a red indicator confirms activation of the safety lock.

Intended Use: The Ypsomed Clickfine AutoProtect Pen Needles are intended for the hypodermic injection of fluids into the body when attached to an injection pen. Additionally, after withdrawal of the pen needle from the body, the attached needle safety shield automatically covers the needle to minimize the risk of accidental needlestick.

As this is a 510(k) for a physical medical device and not an AI/CAD system, several of your requested points are not applicable or the information is not provided because such studies are not typically performed for this type of device.

2. Sample size used for the test set and the data provenance:

  • Sample size: Not specified. The document states "Ypsomed has performed the relevant assessments specified in the following international and internal standards and protocols." The specific number of devices tested for each standard is not provided.
  • Data provenance: Not explicitly stated, but implying tests were conducted in accordance with international standards (ISO) and FDA guidance, likely in a controlled laboratory setting or clinical simulation. It is a prospective assessment of newly produced devices.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Not applicable in the context of device performance testing against engineering standards. "Ground truth" here refers to the specifications and requirements defined by the referenced ISO standards and FDA guidance. Experts would be involved in developing those standards and subsequently in conducting and interpreting the tests, but no specific number or qualifications are mentioned for this particular submission.

4. Adjudication method for the test set:

  • Not applicable in the context of device performance testing against engineering standards. Testing against standards is typically objective measurement against predefined technical specifications.

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 device is a physical pen needle with an automatic safety mechanism, not an AI/CAD system that assists human readers in interpreting medical images or data.

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

  • Not applicable. This is a physical medical device, not an algorithm. The "standalone" performance refers to the device's inherent functional characteristics, specifically its ability to perform injections and activate its safety mechanism as designed. This was assessed through compliance with the listed standards and simulated use studies.

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

  • The "ground truth" for this device's performance is established by the requirements and test methods defined in the cited international standards (ISO) and FDA guidance documents. These standards set the benchmarks for sterility, material properties, mechanical function, biocompatibility, and sharps injury prevention features. Compliance is demonstrated through objective physical and biological testing.

8. The sample size for the training set:

  • Not applicable. This device is not an AI/machine learning model, so there is no "training set."

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

  • Not applicable. As there is no training set for an AI/ML model, this question is irrelevant.
