Intended Use

The Portable Nebulizer is a vibrating mesh nebulizer system designed to aerosolize liquid medications for inhalation by the patient. The device may be used with pediatic (5 years and older), defined by the prescribed medication, and adult patients in hospital/institutional settings, home care use, schools, and long term care facilities.

Device Description

The Portable Nebulizer is a small, handheld, internally powered general purpose nebulizer which utilizes vibrating mesh technology to generate aerosol.

AI/ML Overview

The Portable Nebulizer, a vibrating mesh nebulizer system, underwent non-clinical performance testing to demonstrate its equivalence to the predicate device, Omron NE-U22 (K062263). The assessment primarily focused on aerosol characterization, electrical safety, software verification, biocompatibility, and cleaning/disinfection validation.

Here's an overview of the acceptance criteria and study details:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state "acceptance criteria" for each performance metric with defined thresholds. Instead, it presents a comparative analysis against the predicate device to support substantial equivalence. The reported device performance is generally considered acceptable if it is "similar" or "substantially equivalent" to the predicate, or if it meets established standards.

Shelf-life, Useful-life, Durability TestingNot explicitly stated but implied to meet performance criteria.Testing was performed. Specific performance not detailed in this summary.
Simulated Life Cycle TestingNot explicitly stated but implied to meet performance criteria.Testing was performed. Specific performance not detailed in this summary.

Note: Asterisks () in the "Reported Device Performance" column for particle characterization often indicate that the device's range is different from the predicate's range. However, the overall conclusion in the document is that the results support a substantial equivalence argument.*

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

The document does not explicitly state the sample sizes (number of units or test replicates) for all non-clinical tests. For the particle characterization, the tables show ranges of values for different medications (Albuterol, Ipratropium, Cromolyn), which suggests multiple tests were conducted for each.

The data provenance is not specified in terms of country of origin. The study appears to be entirely retrospective for the purpose of this 510(k) submission, utilizing pre-existing test data to demonstrate equivalence.

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

This information is not provided in the document. The nature of the non-clinical tests (e.g., electrical safety, biocompatibility, particle characterization) typically relies on objective measurements and established standards, rather than expert interpretation of a "ground truth" in the way a clinical study would.

4. Adjudication Method for the Test Set:

This information is not applicable/provided for the non-clinical tests described. Adjudication methods (e.g., 2+1, 3+1) are typically used in clinical studies involving interpretation of data by multiple experts to establish a "ground truth" for diagnostic accuracy or similar endpoints. The tests performed here are objective engineering and material science evaluations.

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:

An MRMC study was not performed as this device is a nebulizer and not an AI-powered diagnostic device involving human readers or interpretation.

6. If a Standalone (i.e. Algorithm Only Without Human-in-the-Loop Performance) Was Done:

This is not applicable as the device is a medical device (nebulizer), not an algorithm or AI system. The "software" mentioned refers to firmware controlling the vibrating mesh, not a standalone AI diagnostic tool.

7. The Type of Ground Truth Used:

For the non-clinical tests, the "ground truth" is established by:

  • Established Standards: For electrical safety (IEC 60601 series), biocompatibility (ISO 10993-1), and software verification (FDA Guidance 337).
  • Objective Measurements: For particle characterization (using Cascade Impactor and laser light scattering techniques), nebulization rate, power consumption, etc.
  • Comparison to Predicate Device: The performance of the Portable Nebulizer is compared directly to the legally marketed Omron NE-U22 (K062263) as key evidence for substantial equivalence.

8. The Sample Size for the Training Set:

This is not applicable as this is a traditional medical device (nebulizer) and not an AI/ML-based device that requires a "training set."

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

This is not applicable for the same reason as point 8.

Device Description:

The Portable Nebulizer is a small, handheld, internally powered general purpose nebulizer which utilizes vibrating mesh technology to generate aerosol.

Components

The Medication Cup contains the nebulizing module where aerosol will be generated. Prescribed medication is placed in the Cup, nebulized and inhaled via the integral mouthpiece.

The Medication Cup is single patient, multi-use. Cleaning is performed after each use by rinsing with distilled water and disinfected via immersion in boiled water for 10 minutes. The performance met its specification criteria of 90 days.

The cup medication capacity is 6 ml.

The Main Unit contains the 2 "AA" batteries and firmware to control the vibrating mesh module in the Medication Cup.

Portable Nebulizer aerosolizes upon turning on by pressing the ON/OFF button and turns off by pressing again or automatically after treatment completion in 30 minutes. To monitor nebulization status and device operating condition, there are different LED colors shown. Normal working condition is indicated by a green while an orange color signifies a malfunction.

There is one model of the subject device.

Indications for Use:

The Portable Nebulizer is a vibrating mesh nebulizer system designed to aerosolize liguid medications for inhalation by the patient. The device may be used with pediatric (5 years and older), defined by the prescribed medication, and adult patients in hospital/institutional settings, home care use, schools, and long term care facilities.

{4}------------------------------------------------

510(k) Summary Page 2 of 7 November 27, 2017

Principle of Operation / Technology

The Portable Nebulizer operates by electrically activating piezoelectric ceramic actuator (PZT) which then transduces the vibration generated to the adjacent supporting plate and polymer mesh bearing numerous apertures. The vibration actively pushes out the liquid medication by physically breaking surface tension of the solution through mesh holes thereby achieving final nebulization. Aerosol generation can subsequently be modulated the vibration frequency that is controlled by the firmware stored within Main Unit to maintain a frequency of approximate 117 kHz, nebulization rate of > 0.25 ml/min and a power consumption of <1.5 W.

510(k) Summary Page 4 of 7 November 27, 2017

Substantial Equivalence Discussion

The Portable Nebulizer is viewed as substantially equivalent to the predicate device because:

Indications for Use – The proposed indications for use are to aerosolize commonly prescribed medications.

Discussion - The indications for use are identical for the proposed device and the predicate -K062263 – Omron NE-U22 nebulizer.

The exclusion of the reference to pentamidine is no longer included in nebulizer indications for use, K150591, and has been removed.

Patient Population - The patient population of adult and pediatric (defined by the prescribed medication) patients that is consistent with the indications for the aerosol medication. This is similar to the predicate - K062263 - Omron NE-U22 nebulizer.

Discussion - The patient population is similar for the proposed device and the predicate -K062263 - Omron NE-U22 nebulizer. The predicate does not describe the pediatric population, however other reference nebulizers have defined the patient population as "pediatric (2 years and older) and / or as "defined by the prescribed medication" - K150591 - Besmed. Thus the differences in the description of the patient population compared to the predicate can be found to be substantially equivalent.

Environment of Use – The proposed environments of use are common and usual for handheld nebulizers, namely Hospital/institutional settings, home care use, schools and long term care facilities.

Discussion - The environment of use is identical for the proposed device and the predicate -K062263 – Omron NE-U22 nebulizer.

Technology - The design as a vibrating mesh nebulizer which is the identical principle of operation.

Discussion - The technology is identical for the proposed device as compared to the predicate -K062263 – Omron NE-U22 nebulizer.
