This document describes the FDA 510(k) premarket notification for a Sterile Syringe for Single Use (with Needle) and a Sterile Hypodermic Needle for Single Use by Jiangsu Zhiyu Medical Instrument Co., Ltd. The submission aims to demonstrate substantial equivalence to a legally marketed predicate device (K201284).

However, the provided text does not contain details about a study conducted to prove the device meets acceptance criteria in the context of an AI/human reader performance study. The document is a regulatory submission for a physical medical device (syringes and needles) and focuses on demonstrating substantial equivalence through bench testing (per ISO standards) and biocompatibility testing.

Therefore, I cannot provide the information requested in your prompt regarding:

• A table of acceptance criteria and reported device performance related to AI/human reader studies. The acceptance criteria discussed pertain to physical properties and safety of the syringe/needle, not diagnostic performance.
• Sample size and data provenance for an AI test set.
• Number of experts and qualifications for ground truth establishment for an AI study.
• Adjudication method for an AI test set.
• MRMC comparative effectiveness study results (AI vs. without AI assistance).
• Standalone (algorithm only) performance.
• Type of ground truth used (expert consensus, pathology, outcomes data) for an AI study.
• Sample size for the training set (for an AI model).
• How ground truth for the training set was established (for an AI model).

The document explicitly states: "No clinical study is included in this submission." This further confirms that no studies involving human reader performance comparisons or algorithm-only performance for diagnostic purposes (the typical context for MRMC or standalone AI studies) were conducted or submitted.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done:

• No. The document explicitly states: "No clinical study is included in this submission."

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

• No. This is not an AI device.

7. The type of ground truth used:

• The "ground truth" for this device's performance is defined by the specifications and acceptable limits set forth in the referenced ISO and USP standards. This includes, for example, specific force required to move a plunger, volume accuracy, needle sharpness, and biocompatibility limits. It is established through physical measurements and laboratory assays.

8. The sample size for the training set:

• Not applicable. This device does not use a training set as it is not an AI/ML device.

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

• Not applicable.

In summary, the provided document is for a conventional medical device (syringes and needles) seeking 510(k) clearance based on substantial equivalence to a predicate device, demonstrated through rigorous bench testing and adherence to recognized performance and safety standards, not through AI performance studies.

The provided document is a 510(k) Summary for a Sterile Syringe for Single Use. It focuses on demonstrating substantial equivalence to a predicate device rather than detailing an AI/ML powered device. Therefore, many of the requested categories related to AI/ML device studies (such as MRMC studies, training set details, or ground truth establishment for AI models) are not applicable.

However, based on the information provided, here's a breakdown of the acceptance criteria and the study that proves the device meets those criteria, interpreted within the context of a medical device clearance:

1. A table of acceptance criteria and the reported device performance

The document defines "acceptance criteria" through compliance with recognized standards and the demonstration of substantial equivalence to a predicate device. The performance is reported as meeting these standards.

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

The document does not specify exact sample sizes for each non-clinical test conducted. It states "Non-clinical tests were conducted to verify that the proposed device met all design specifications." The data provenance is implied to be from internal testing conducted by Jiangsu Suyun Medical Material Co., Ltd. or its contracted labs, with the country of origin being China (where the manufacturer is located). The testing is prospective for the purpose of this submission, meaning the tests were performed on the proposed device to gather data for regulatory submission.

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

This question is not applicable. The "ground truth" for a medical device like a sterile syringe is based on established engineering and biological standards (e.g., ISO, ASTM, USP) and laboratory measurements, not subjective expert assessment in the way it would be for an AI diagnostic tool. The "experts" involved are the certified laboratory technicians and quality control personnel who perform and interpret these standardized tests. Their qualifications are inherent in their ability to conduct these specific tests according to recognized protocols.

4. Adjudication method for the test set

This is not applicable in the context of this device and type of testing. The tests are typically objective measurements against defined pass/fail criteria in the standards. There is no mention of a human adjudication process for resolving conflicting results, as would be common in image interpretation studies.

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

This is not applicable. The device is a physical sterile syringe, not an AI/ML-powered diagnostic or assistive tool.

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

This is not applicable. The device is a physical sterile syringe, not an algorithm.

7. The type of ground truth used

The "ground truth" for this device's performance relies on objective measurements from standardized non-clinical tests. These include:

• Biological/Chemical endpoint measurements: e.g., cell viability (cytotoxicity), skin reactions (irritation/sensitization), blood cell lysis (hemolysis), particulate counts, endotoxin levels.
• Physical performance measurements: e.g., seal strength, leak detection, plunger force, barrel integrity, needle sharpness and elasticity.
• Sterility verification: Growth/no-growth tests for sterility assurance.

The "ground truth" is defined by the Pass/Fail criteria specified within the referenced ISO, ASTM, and USP standards.

8. The sample size for the training set

This is not applicable. There is no AI/ML component or "training set" for this sterile syringe device. The document describes non-clinical performance testing.

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

This is not applicable. As there is no AI/ML component, there is no training set and no ground truth established for one.
