Intended Use

The Nerve Block Infusion Kit is intended to provide continuous infusion of a local anesthetic near a nerve for regional anesthesia and pain management for pre-operative, perioperative and postoperative general and orthopedic surgery. Additional routes of infusion include percutaneous, subcutaneous, epidural and into the intraoperative (soft tissue / body cavity) site and synovial cavity.

Device Description

The Nerve Block Infusion Kit is nearly identical to the I-Flow PainBuster Infusion Kit with the exception of a new intended use, the addition of three new pump models and the addition of three new kit components (insulated Tuohy needle, hemostasis valve assembly and hookup wire). The kit is comprised of an elastomeric infusion pump (K944692) and various components such as catheter, needle, syringe, dressing, tape, gauze, hemostasis valve assembly, hookup wire and accessories such as carry case, power ring and clothing attachment clip (E-Clip). The Nerve Block pump is a disposable device intended for single patient use. The Nerve Block pump is suitable for use as an ambulatory device and is intended for use in the hospital, home environment or alternative care sites.

AI/ML Overview

Here's an analysis of the provided text regarding the Nerve Block Infusion Kit, focusing on acceptance criteria and the study that proves the device meets them:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria CategorySpecific CriteriaReported Device Performance
Flow Rate Accuracy±15% at 95% confidence interval"All models produced an average flow rate within the ±15% accuracy claim."

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size: Not explicitly stated. The document mentions "nominal fill volumes for each model" but does not provide specific numbers of pumps or tests conducted.
  • Data Provenance: Not explicitly stated, but it is implied to be internal testing conducted by I-Flow Corporation ("Testing occurred at standard operating conditions. Testing occurred at nominal fill volumes for each model."). There is no mention of external validation or data from specific countries. It is prospective in nature, as the testing was performed to support the premarket notification.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. The study is a performance test of a medical device (infusion pump flow rate) and does not involve human expert interpretation or a "ground truth" in the clinical sense. The ground truth here is the physical measurement of the flow rate against a specified engineering tolerance.

4. Adjudication Method for the Test Set

Not applicable. This was a technical performance test, not a subjective assessment requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

Not applicable. This device is an elastomeric infusion pump, not an AI-powered diagnostic or assistive technology involving human readers.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, a standalone performance test was done. The device (Nerve Block pump) was tested to measure its flow rate performance against pre-defined accuracy claims. This refers to the intrinsic performance of the pump itself, independent of human interaction during operation beyond initial setup.

7. The Type of Ground Truth Used

The ground truth used was engineering specification/measurement against a defined tolerance. The "ground truth" for flow rate accuracy is the desired flow rate, and the measured flow rate must fall within ±15% of that desired rate at a 95% confidence interval.

8. The Sample Size for the Training Set

Not applicable. This is a mechanical device, not a machine learning model, so there is no concept of a "training set."

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set for this type of device.

§ 880.5725 Infusion pump.

(a)
Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)
Classification. Class II (performance standards).
