Intended Use

The PORTEX® Tuohy and Hustead Needles with NRFif™ connectors are intended to facilitate the placement of an epidural catheter and for the injection or infusion of regional anesthetics or narcotics.

Device Description

The sterile, single use Tuohy and Hustead needles with NRFit™ connector are for insertion into the epidural space for either single shot doses of anesthetic or narcotics or as an introducer for epidural catheters or spinal needles. The Tuohy needles are marked at 10 mm graduations to enable the depth of needle insertion to be determined. The Tuohy needles are supplied with a removable wing which allow the needle to be used as a winged or non-winged needle. The stylet hub is color-coded for ease of identification. The intended target population is pediatrics and adults.

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

The document does not specify the exact sample sizes used for each test. It broadly states that "All testing met pre-established specifications."

The data provenance is from non-clinical performance testing, meaning these are laboratory tests on the device itself, not clinical data from patients. There's no information about country of origin for the data or whether it's retrospective or prospective, as it's not clinical data.

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 section is not applicable. The "ground truth" in this context refers to established standards (e.g., ISO, ANSI/AAMI, USP) and the physical properties and performance of the device. There were no human experts establishing ground truth for a diagnostic outcome, as this is a device for fluid delivery and catheter placement, not a diagnostic imaging device.

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

This section is not applicable. Adjudication methods are typically used in clinical studies where expert consensus is needed for ambiguous cases. These were non-clinical, objective tests against established 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

This section is not applicable. This document describes the testing for an epidural needle, not an AI-powered diagnostic device. Therefore, no MRMC study or AI assistance evaluation was performed.

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

This section is not applicable. This document describes the testing for a physical medical device (epidural needle), not an algorithm or AI system.

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

The "ground truth" for the non-clinical testing was established by recognized international and national standards and test methods. These include:

  • ISO 80369-6 (for connectors for neuraxial applications)
  • ISO 9626-2016 (for stiffness and bending force of needles)
  • PWI-10005073-Test Method for Needle Penetration Force
  • ISO 11607 (for packaging)
  • ISO 11135 (for sterilization)
  • ISO 10993 series (for biocompatibility)
  • ANSI/AAMI ST72 (for bacterial endotoxins)
  • USP 788 (for particulate matter)

These standards define the acceptable performance parameters and methodologies for testing.

8. The sample size for the training set

This section is not applicable. This document describes the testing of a physical medical device, not a machine learning model, so there is no "training set."

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

This section is not applicable. As there is no training set for a machine learning model, the concept of establishing ground truth for it does not apply here.
