Characters comparison {6}------------------------------------------------ ## Similar #1 The safety lancet typically comprises three components, housing, needle, and spring. The component of the housing is mainly plastic. The component of the needle is stainless steel, and the spring consists of steel. Although the proposed and predicate devices use different materials, the types of components are unchanged. Besides, the performance testing reports, and biocompatibility testing reports show all the testing items meet requirements. This difference on materials has a minimal impact on the performance of the products. In conclusion, the proposed device and predicate device are substantially equivalent. #### Similar #2 The proposed device has six types of gauges, more than the predicate device, like 30G normal needle and 21G blade needle. Meanwhile, the proposed device has a new type-blade beveled needle tip. The differences between the blade and regular beveled tip are the beveled angle {7}------------------------------------------------ and beveled face number; the blade beveled tip has a smaller bevel angle than the regular one, but more beveled faces. The needle length of the proposed device is included in the length range of the predicate device. The performance testing (e.g., needle removal force, puncture force testing) results demonstrated that the proposed device can be used safely and effectively. In conclusion, the proposed device and predicate device are substantially equivalent. #### Similar #3 The different methods to remove the protective cap will not affect sharps injury protection. The related report has verified the sharps injury protection function of the device. The needle tip is molded in plastic housing to ensure sterility. The different ways of activating the safety lancet do not influence the performance. In conclusion, the proposed device and predicate device are substantially equivalent. #### Similar #4 The exposed needle length/depth falls within the range of the Predicate device. The performance testing report verifies the proposed device's sharps injury protection function. In conclusion, the proposed device and predicate device are substantially equivalent. ## Different #5 The cap removal type is different. Unlike the predicate device twisting off the cap, the proposed device pulls off the cap. The cap removal force testing demonstrates the proposed device meets the internal requirements 3°9N; these requirements are similar to other cleared lancets. In conclusion, the proposed device and predicate device are substantially equivalent. ## 8. Non-clinical testing results ## (1) Physical performance testing The proposed device's physical performance was tested to evaluate the overall nonclinical performance. Results demonstrated the device's safety and effectiveness by the following main items. - । Cap removal force testing. {8}------------------------------------------------ Cap removal force testing was conducted in compliance with the manufacturer's internal requirements 3~9 N to ensure that end users could easily remove the cap without getting hurt. - -Needle removal force/Firmness Needle removal force testing was conducted in compliance with the requirements of ISO 7864:2016 to ensure the needle's firmness by bonding with the hub. - -Drop testing. Drop testing was conducted in compliance with the requirements of IEC 60068-2-32:1993, that the needle tip would not be exposed when it was dropped from a table with a fixed height. - -Puncture force testing. Puncture force testing was conducted in compliance with the requirements of ISO 7864:2016. The force was as low as possible to ensure the needle easily punctured the patients' skin. - -Safety Feature testing. The safety features were verified in compliance with the requirements of ISO 23908:2011 and Guidance for Industry and FDA Staff Medical Devices with Sharps Injury Prevention Features Document Issued on: August 9,2005, to ensure end users' safe use. Other physical performance testing was conducted in compliance with the following standards. - (a) ISO 9626:2016 Stainless Steel Needle Tubing for the Manufacture of Medical Device. - (b) ISO 7864:2016 Sterile hypodermic needles for single use requirements and test methods ## (2) Sterility and Shelf-life - (a) ISO 11737-1:2018, Sterilization of health care products Microbiological methods Part 1: Determination of a population of microorganisms on products. - (b) ISO 11737-2:2019, Sterilization of health care products Microbiological methods Part 2: Tests of sterility performed in the definition, validation and maintenance of a sterilization process. - (c) ISO 11137-1:2006, Radiation of medical devices part 1: Requirements for the development, validation and routine control of the sterilization process of medical devices. - (d) ISO 11137-2:2013, Radiation sterilization of medical devices part 2: Determination of sterilization dose. - (e) ISO11137-3: 2017, Radiation sterilization of medical devices part 3: Dosage guidelines. - (f) ISO 11607-1:2019, Packaging for terminally sterilized medical devices Part 1: Requirements for materials, sterile barrier systems and packaging systems - (g) ASTM F1980: Standard for Accelerated Aging of Sterile Barrier Systems and Medical Devices - (h) ASTM D4169-16, Standard Practice For Performance Testing Of Shipping Containers And {9}------------------------------------------------ Systems - (i) USP <71> Sterility Test #### (3) Biocompatibility testing - (a) ISO10993-1:2018, Biological evaluation of medical devices Part 1: Evaluation and testing within a risk management process. - (b) ISO 10993-5:2009, Biological evaluation of medical devices Part 5: Tests for in vitro cytotoxicity. - (c) ISO 10993-10:2010, Biological evaluation on medical device Part 10: Test for irritation and Skin Sensitization. - (d) ISO 10993-11:2017, Biological evaluation of medical devices Part 11: Tests for systemic toxicity. - (e) USP <85> Bacterial Endotoxins Test - (f) USP <788>Particulate matter in injection - (g) USP <161>Medical Devices-Bacterial endotoxin and pyrogen tests ## (4) Simulated clinical use testing A simulated clinical use study was conducted on 500 device samples in compliance with the Guidance for Industry and FDA Staff Medical Devices with Sharps Injury Prevention Features Document Issued on: August 9, 2005. Results demonstrated the device's effectiveness and safety in a simulated clinical condition. ## 9. Clinical testing No clinical testing is available for this device. #### 10. Conclusion The differences between the predicate and the proposed device do not raise any new or different questions of safety or effectiveness. The proposed device is substantially equivalent to the predicate device with respect to indications for use and technological characteristics.
