Shina Syringe; Shina Safety Syringe
Shina Syringe, Shina Safety Syringe is a plastic sterile syringe and hypodermic single lumen needle intended to be used for medical purpose to inject fluid into or withdraw fluid from body.
A sterile device consisting of a calibrated barrel (cylinder) with plunger intended to be used for injection/withdrawal of fluids/gas (e.g., medication) to/from a medical device or the body (i.e., capable of both); a needle is (not) included. lt is intended for various medical applications and is not dedicated to medication administration. At the distal end of the barrel is a male connector (typically Luer-lock/slip type) for the attachment to a hypodermic needle or an administration set. It is typically made of plastic and silicone materials and may have anti-stick plunger allowing smooth plunger movement, either manually or by a syringe pump. This is a single-use device.
This document describes the acceptance criteria and study proving the device meets those criteria for the Shina Syringe and Shina Safety Syringe.
The listed information primarily focuses on bench testing for mechanical, physical, and biocompatibility properties, rather than effectiveness studies involving human subjects or AI-assisted diagnoses. Therefore, several requested sections, particularly those related to clinical studies, human readers, ground truth establishment for training sets, and effect sizes of AI assistance, are not applicable based on the provided text.

2. Sample size used for the test set and the data provenance
The document does not explicitly state the sample size for each bench test conducted. The provenance of the data is that these are bench tests conducted by the manufacturer, Shina Med Corporation, in the Republic of Korea. The studies are by nature retrospective in the context of device development, where the device is manufactured and then tested to established standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This section is not applicable. The ground truth for these types of mechanical, physical, and biocompatibility tests is established by published international standards (ISO, USP, ASTM), not by expert consensus in diagnostic interpretation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This section is not applicable. Adjudication methods are typically used in clinical studies involving interpretation of medical data by multiple experts. The reported studies are bench tests against defined international standards.
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 section is not applicable. No MRMC comparative effectiveness study was performed or discussed, as the device is a syringe and needle, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This section is not applicable. The device is a physical medical device (syringe and needle) and does not involve an algorithm or AI.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The ground truth used for these tests are established international and national standards for medical devices, specifically:
- ISO 7886-1: Sterile hypodermic syringes for single use
- ISO 7864: Sterile hypodermic needles for single use
- ISO 9626: Stainless steel needle tubing
- USP : Particulate Matter in Injections
- ISO 23908: Sharps injury protection
- ISO 10993 series for Biological evaluation of medical devices (Parts 4, 5, 7, 10, 11, 23)
- ASTM F756-17: Standard Practice for Assessment of Hemolytic Properties of Materials
8. The sample size for the training set
This section is not applicable. As this is a physical medical device submission focusing on bench testing, there is no AI model or "training set" in the context of machine learning.
9. How the ground truth for the training set was established
This section is not applicable for the same reasons as section 8.
