Intended Use

The syringe as supplied is a device with a small barrel, plunger and fixed needle, calibrated in units of insulin (U-100), to be used to administer (infuse) insulin subcutaneously. It incorporates features that include reuse prevention and sharps injury prevention.

Device Description

The 1mL Unitract® Insulin Syringe is a sterile, fixed needle, single use, insulin (U-100) syringe, consisting of a barrel and plunger assembly. The syringe is supplied in two needle sizes, being 27G x ½" and 29G x ½".
The devices function in a manner similar to standard syringes for filling and mixing insulin and subcutaneous injection, but also incorporates a sharps injury prevention (automatic needle retraction) and reuse prevention (auto disable) feature.
The sharps injury prevention feature allows for automatic and full retraction of the needle into the syringe barrel immediately after the full dose has been expelled; where the rate of retraction may be controlled by the user. The reuse prevention feature also engages immediately after retraction, which prevents further movement of the plunger in either direction.

AI/ML Overview

I am sorry, but the provided text does not contain information about acceptance criteria or a study proving the device meets acceptance criteria as typically associated with medical device performance (e.g., sensitivity, specificity, accuracy for diagnostic devices, or specific numerical performance targets for other devices).

The document is an abbreviated 510(k) summary for the Unilife 1mL Unitract® Insulin Syringe. It focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed performance study results against predefined acceptance criteria for the device's primary function in terms of a clinically measured outcome or a specific performance metric.

Here's an breakdown of the types of information that are present, and what is missing for your request:

What is present in the document:

  • Non-Clinical Performance Data: It mentions that mechanical performance tests were conducted to verify the device meets design specifications based on FDA Consensus Standard ISO 8537:1991 and AS 1077:1992.
  • Specific Tests Conducted: It lists "Additional performance testing was conducted on the safety features relating to peak activation forces of the retraction mechanism, spring reaction forces and forces to override the auto disable feature." It also mentions chemical testing (Reducing Matter, Extractable Trace Metals, Non-Volatile Residue, pH and chemical residues) and biocompatibility testing (Cytotoxicity and Pyrogens).
  • Sterilization Validation: Sterilization processes are validated to DIN EN 550:1994 to a sterility assurance level (SAL) of 10^-6.
  • Manufacturing Process Control: States that functional, chemical, and biological tests are performed on each production lot number.
  • Conclusion: The device is deemed "substantially equivalent" based on performance testing, intended use, and design principles, and "any differences cited do not raise any new questions of safety and effectiveness."

What is missing from the document (and therefore I cannot provide in the requested format):

  1. A table of acceptance criteria and the reported device performance: While standards are mentioned (ISO 8537, AS 1077, DIN EN 550), the specific numerical acceptance criteria from these standards and the actual numerical results of the device's performance against those criteria are not detailed. For example, it doesn't say "peak activation force must be X-Y Newtons; our device measured Z Newtons."
  2. Sample size used for the test set and the data provenance: Not mentioned for any of the performance tests.
  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 a physical device, not an AI/diagnostic software.
  4. Adjudication method for the test set: Not applicable.
  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.
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
  7. The type of ground truth used: For physical testing, the ground truth would be the objective measurement against the specified standard/design requirement, but the specifics aren't provided.
  8. The sample size for the training set: Not applicable as it's not an AI/algorithm.
  9. How the ground truth for the training set was established: Not applicable.

In essence, this document provides a high-level summary of the types of tests done to support a 510(k) submission, confirming adherence to relevant standards and design specifications, but it does not delve into the detailed quantitative results required to fulfill your request for specific acceptance criteria and reported performance metrics.

SubstantialEquivalence:The 1mL Unitract® Insulin Syringe has identical indications for use and similar features to the cited predicate # K050134 which is to infuse insulin subcutaneously; whilst incorporating a sharps injury prevention feature. In addition, the spring based mechanism of the cited predicate # K023752; and how this mechanism is integrated within the design of the 1mL Unitract® Insulin Syringe do not raise new questions of safety and effectiveness.
TechnologicalCharacteristics:The 1mL Unitract® Insulin Syringe has similar needle retraction mechanisms to the cited predicate # K050134. The syringe is filled; and at the end of the injection stroke once the full dose has been expelled, the plunger engages the needle to allow retraction into the syringe barrel. The cited predicate device relies on manual retraction and plunger fracture, where the 1mL Unitract® Insulin Syringe uses a spring based mechanism to retract the needle. The auto disable feature of the 1mL Unitract® Insulin Syringe is integrated within the plunger design, where after full retraction, the plunger engages with the collar outer to prevent movement of the plunger in either direction. This feature requires no secondary action by the user to disable the syringe. The characteristics of the 1mL Unitract® Insulin Syringe spring based mechanism are similar to the technology of the cited predicate # K023752. The spring mechanism of this predicate device is located at the distal end of the syringe which facilitates the retraction of the needle into the plunger. The 1mL Unitract® Insulin Syringe spring mechanism is located on the proximal end of the syringe to allow retraction into the barrel. The design of the 1mL Unitract® Insulin Syringe integrates the technological design characteristics of the cited predicates, and having similar operating procedures for filling and mixing insulin, aspiration and injection, has been demonstrated to have no significant differences.
The syringe components are manufactured from USP Class VI materials and stainless steel.
Non ClinicalPerformance Data:Mechanical performance tests were conducted to verify the device meets design specifications based on the requirements of the FDA Consensus Standard ISO 8537:1991 Sterile single-use syringes, with or without needle, for insulin and the voluntary standard AS 1077:1992, Single-use syringes (sterile) for the injection of 100 units per millilitre insulin (U- 100). Additional performance testing was conducted on the safety features relating to peak activation forces of the retraction mechanism, spring reaction forces and forces to override the auto disable feature. Chemical testing included Reducing (Oxidisable) Matter, Extractable Trace Metals, Non-Volatile Residue, pH and chemical residues (EO Sterilisation). Biocompatibility testing of the finished devices included Cytotoxicity and Pyrogens; with all materials in the fluid path meeting USP Class VI requirements.
