Intended Purpose: The K-Pack Embrace™ Active Safety Needle, being a hypodermic needle with safety shield, is intended to inject fluids into, or withdraw fluids from, parts of the body below the surface of the skin. The safety shield shall be manually locked (activated), after use, to cover the needle to minimize the risk of accidental needle stick.

Indications: The K-Pack Embrace™ Active Safety Needle is for general application – for treatment (injection of fluids) or diagnosis (withdrawal of fluids).

The K-Pack Embrace™ Active Safety Needle is a hypodermic single lumen needle, for single use consisting of stainless steel cannula that is sharpened at one end and at the other end joined to a female luer connector (hub) made of polycarbonate designed to be connected with a male luer connector (nozzle) of a hypodermic syringe. The K-Pack Embrace™ Active Safety Needle is compatible for use with standard luer slip and luer lock syringes. The K-Pack Embrace™ Active Safety Needle is packed in a hard plastic container (cap and case) made of polypropylene and sealed with a label.

This device features a hinged safety shield, made of polycarbonate, attached to the needle hub. The safety feature is activated when the safety shield is manually pressed over the needle immediately after use and prior to disposal to minimize the risk of accidental needle stick injuries. The safety shield is activated with a one-handed operation, using the finger, thumb, or surface activation.

The K-Pack Embrace™ Active Safety Needle is sterilized by ethylene oxide.

I am sorry, but the provided text from the FDA 510(k) Clearance Letter for the K-Pack Embrace™ Active Safety Needle does not contain the specific information required to describe the acceptance criteria and the study that proves the device meets those criteria in the way you've requested (e.g., details about AI studies, sample sizes for training/test sets, expert adjudication, MRMC studies, and nuanced ground truth establishment).

The document is a standard 510(k) clearance letter for a medical device (a hypodermic needle with a safety shield) that demonstrates substantial equivalence to a predicate device. The "Non Clinical Test" section focuses on:

• Performance testing: Verification of the device's design against recognized international standards (ISO 7864, ISO 9626, ISO 80369-7, ISO 6009, ISO 23908, ISO 11607-1, USP , and FDA guidance on sharps injury prevention). These standards define various physical and functional requirements for hypodermic needles and their safety features.
• Biocompatibility testing: Evaluation of the materials in contact with the body according to ISO 10993.
• Sterilization and shelf-life testing: Validation of the sterilization method (Ethylene Oxide) according to ISO 11135 and shelf-life studies according to ASTM F1980.

The document does not describe an AI/ML-based device or a study involving human readers, AI assistance, ground truth established by experts, or any of the elements typically associated with the kind of acceptance criteria you've detailed in your prompt (e.g., sensitivity, specificity, AUC for an AI model).

Therefore, I cannot populate the table or answer the specific questions related to AI/ML study design and expert review methodology based on the provided text. The device described is a physical medical device, not a diagnostic AI system.
