Disposable Insulin Pen Needle(Model CT) : Disposable Insulin Pen Needle is intended for use with pen injector device for subcutaneous injection of insulin.
Disposable Insulin Pen Needle(Model ST) : Disposable Insulin Pen Needle is intended for use with pen injector device for subcutaneous injection of insulin. Additionally, it has sharps injury protection feature that it can reduce the occurrence of accidental needlesticks from the patient end of the needle due to the effect of safe-lock guard.
Disposable Insulin Pen Needle, could be divided into Model CT (normal type) and model ST(safety type) according to whether there is sharps protection features. Model CT consists of needle hub, needle container, needle tube, needle shield and seal (dialyzing paper). Model ST consists of needle hub, needle container, protective cap, needle tube, spring, slider, protective jacket and seal (dialyzing paper). The device is sterilized by EO gas and for single use. The shelf life is 5 years.
Needle tube is fixed in the center of the needle hub with UV glue, the needle tip is protected with needle shield or protective jacket before use, medical dialyzing paper is covered and sealed needle container to maintain sterile of the cartridge end of needle can be inserted into the rubber of insulin pen, meanwhile the needle hub is connected to insulin pen with screw thread to provide sterile fluid path for injection of insulin during use. When Disposable Insulin Pen Needle is connected to insulin pen operates on the principles of common piston syringes. The patient end and the cartridge end of the needle tube are lubricated with silicone oil for ease of injection and rubber penetration.
Model ST has sharps injury protection feature that it can reduce the occurrence of accidental needlesticks from the patient end of the needle due to the effect of safe-lock guard.
The provided text is a 510(k) Premarket Notification for a Disposable Insulin Pen Needle. It focuses on demonstrating substantial equivalence to predicate devices through design comparisons and a summary of performance testing. The document does not describe a study that involves acceptance criteria for device performance based on AI or diagnostic accuracy. Instead, it details the physical and functional performance of the device based on established medical device standards.
Therefore, I cannot provide information about:
- A table of acceptance criteria and reported device performance related to diagnostic accuracy or AI.
- Sample size used for the test set and data provenance for an AI model.
- Number of experts used to establish ground truth or their qualifications.
- Adjudication method for a test set.
- MRMC comparative effectiveness study or human reader improvement with AI.
- Standalone algorithm performance.
- Type of ground truth used (expert consensus, pathology, outcomes data).
- Sample size for the training set.
- How ground truth for the training set was established.
However, I can extract information regarding the device's general performance testing and criteria based on the provided document:
The device's performance is evaluated against recognized international standards for medical devices and sterility.
Here's a summary of the performance testing and criteria mentioned, which serves as the "acceptance criteria" in the context of this medical device submission:

2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a distinct "test set" in the context of diagnostic performance or AI. Instead, it refers to samples of the device being manufactured and subjected to various physical, chemical, and biological tests according to the standards listed above. The provenance of these test samples would be the manufacturer's production line (Ningbo Medsun Medical Co., Ltd., China). The tests are prospective in the sense that they are performed on the manufactured device models to demonstrate compliance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable, as this is not a diagnostic device involving expert interpretation or AI. The "ground truth" here is compliance with established international and national medical device standards, which are defined by committees of experts in the field.
4. Adjudication Method for the Test Set
Not applicable. The criteria are objective measurements and validations against 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
Not applicable, as this is not a diagnostic device or AI-driven system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable, as this is a physical medical device.
7. The type of ground truth used
The "ground truth" is defined by the technical specifications and performance requirements outlined in the cited international and national standards (e.g., ISO 11135, ISO 11608-2, ISO 9626, ISO 7864, ISO 10993 series, ASTM D4169-16, ASTM F1929-2015, USP , ISO 23908:2011). These standards represent established scientific and engineering principles for medical device safety and efficacy.
8. The Sample Size for the Training Set
Not applicable, as this is not an AI/ML device.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as this is not an AI/ML device.
§ 880.5570 Hypodermic single lumen needle.
(a)
Identification. A hypodermic single lumen needle is a device intended to inject fluids into, or withdraw fluids from, parts of the body below the surface of the skin. The device consists of a metal tube that is sharpened at one end and at the other end joined to a female connector (hub) designed to mate with a male connector (nozzle) of a piston syringe or an intravascular administration set.(b)
Classification. Class II (performance standards).
