2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document describes bench testing for physical characteristics, dimensional verification, and biocompatibility, not a clinical study with a "test set" in the context of AI or diagnostic performance. Therefore, typical sample size or data provenance details for medical image analysis are not applicable. The testing was conducted to verify compliance with engineering standards (ISO standards). The document does not specify the exact number of units tested for each specific test, but mentions "All necessary bench testing was conducted."

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable as the device is a physical medical device (syringes, needles, etc.) and its performance is evaluated against engineering and biological standards, not diagnostic interpretations from experts. Ground truth is established by objective measurements against specified engineering and material science criteria.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This device is not an AI diagnostic tool and does not involve human adjudication of results in the traditional sense of a clinical study or image interpretation.

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. The DASH 6® NRFit System is a medical device (syringes, needles, etc.) and not an AI-powered diagnostic or assistive tool.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This device is not an algorithm or AI system. Its performance is evaluated intrinsically based on its physical properties and adherence to manufacturing and safety standards.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for this device's evaluation is primarily the specifications and requirements defined by international standards (e.g., ISO 80369-6, ISO 7886-1, ISO 10993 series) and the manufacturer's own design specifications. It is based on objective, quantifiable physical and chemical measurements (e.g., fluid leakage, dimensions, material compatibility).

8. The sample size for the training set

Not applicable. There is no "training set" as this is a physical medical device, not a machine learning model.

9. How the ground truth for the training set was established

Not applicable.

The devices operates exactly the same way as the predicate device. The 5 Micron Straw Filter listed in the Arrow Epidural Catheter Kit is also used as a reference predicate as the filter straw will be packaged in to an Anesthetic conduction kit. The only difference is the connection system on the connector of the straw hub.

The DASH 6® NRFit Blunt Drawing Up Needle (with and without filter) are equivalent to that of the filter needle supplied in the CorrectInject kit and the twin Pack Syringe filling device supplied by BD. The blunt needle operates the same way as the predicate devices and has the same intended use. The only difference is the connection system on the connector of the needle hub.

The DASH 6° NRFit Bacterial Disc Filter and Epidural Flat Filter are equivalent to that of the Portex supplied in the CorrectInject kit. The filters operated exactly the same way as the predicate devices and has the same intended use. The only difference is the connection system on the housing.

The DASH 6 ° NRFit Tuohy-Borst Adapter are equivalent to that of the Tuohy borst adaptor supplied in the EpiLong set for Anesthesiology, supplied by Pajunk.

DASH 6 ° NRFit Syringe to Syringe Adapter are a Class I accessory. The connection system contains two female ISO 80369-6 NRFit connectors.

DASH 6 ° NRFit Epidural Catheter Feeder are equivalent to that of the Thread assist guide contained in the Busse Epidural Catheter Kit. The Epdirual operated exactly the same way as the predicate devices and has the same intended use. The only difference is the connection system on the accessory.

{15}------------------------------------------------

The differences in the technological characteristics between the devices and accessories do not raise any new issues of safety or effectiveness. Thus, the DASH 6° NRFit Syringe device family and accessories (DASH 6 ° NRFit Syringe Cap, DASH 6 ° NRFit Drawing Up Straw with Filter, DASH 6® NRFit Blunt Drawing Up Needle (with and without filter), DASH 6° NRFit Bacterial Disc Filter, DASH 6° NRFit Epidural Flat Filter, DASH 68 NRFit Tuohy-Borst Adapter, DASH 66 NRFit Syringe to Syringe Adapter, DASH 6® NRFit Needle Hub Cap, DASH 6® NRFit Epidural Catheter Feeder) are substantially equivalent to their predicate devices.

5.6.2 Testing in Support of Substantial Equivalence Determination

All necessary bench testing was conducted on the DASH 6° Family of devices to support a determination of substantial equivalence to the (primary) predicate and the associated accessories. Testing included biocompatibility, sterilization validation, shipping and packaging, accelerated aging, and design verification testing. Design verification testing included the following:

Visual inspection
Dimensional verification
Physical testing

Performance testing was conducted to confirm compliance to the design specifications of ISO 80369-6; all functions have been verified to operate as designed. The DASH 6 Syringe device family, its male NRFit connector and its accessories (with female NRFit connectors) have met all acceptance criteria, as described in Section 18.

5.6.3 Tests Defined in ISO 80369-6 and 80369-20 for NRFit Connectors

Resistance to overriding	Annex H

{16}------------------------------------------------

Dimensional analysis was conducted for critical dimensions of the DASH 6® NRFit Syringe device family and its accessories (with NRFit connectors), in accordance with the criteria in ISO 80369-6.

Device Verification Testing for the piston syringe was conducted in accordance with ISO 7886-1 (Capacity Tolerance, Leakage Testing Side Force, Leakage Testing Axial Force). Cytotoxicity, Sensitization, and Extractables and Leachables testing was also done per ISO 10993-5, 10993-10, and 10993-18 and 10993-19, respectively.

The DASH 6 NRFit plastic LOR device itself did not undergo testing according to due to its intended use. The LOR device is a low friction device and it is used to locate the epidural space. The requirement for low friction and integrity of the seal from the gasket to the barrel is therefore compromised to produce the required clinical function to enable the physician to locate the epidural space. As such, to test the performance for "leakage and resistance" for the LOR device will not be testable under the regime of ISO 7886-1 as it is not applicable.

Design verification testing for the needles were conducted in accordance with ISO 7864-1 but only in certain respects (i.e. Needle to Needle Hub bonding, dimensions tolerances and blockages within the needle). The reason for this is that the DASH 6 NRFit needles are not intend for administering medication. Therefore, certain characteristic aspect of specified in ISO 7864-1, were taken into account for these needles.

Design verification testing were completed on the filter device to ensure that the device is also functioning according to it requirement. This includes the bubble point test, flow-rate and filtration efficiency.

The risk associated with misconnection of the NRFit connector has been assessed and the process captured in the following documents:

FMEA (Design, User, Process)
Risk Management Report

The collective results of the testing demonstrate that the DASH 6® NRFit Syringe device family and accessories meet specifications and perform as intended. In addition, the collective bench testing demonstrates that the DASH 6® NRFit Syringe device family and accessories do not raise new questions of safety or effectiveness as compared to the predicate or the associated accessories.

5.7 CONCLUSION

The DASH 6 ° NRFit Syringe family and accessories have the same intended use and similar technological characteristics as the predicate devices. The DASH 6 NRFit Syringe family and accessories have been tested to ensure that they perform as intended and do not raise new questions of safety or effectiveness. As such, the DASH 6 NRFit Syringe device family and accessories are substantially equivalent to the predicate and the associated accessories.
