The InnoSpire Go is a vibrating mesh nebulizer system designed to aerosolize liquid medications for inhalation by the patient. The device may be used with pediatric (2 years and older), defined by the prescribed medication, and adults patients in the home environment or in a hospital/clinic setting.
The InnoSpire Go nebulizer is a small, handheld, internally powered nebulizer which utilizes vibrating mesh technology to generate aerosol.
The provided document describes the InnoSpire Go nebulizer's acceptance criteria and the study that proves it meets those criteria, primarily through comparison to a predicate device, the Aerogen AeroNeb Go.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are not explicitly stated as distinct pass/fail thresholds but are implied through the comparison to the predicate device's performance, aiming for "substantially equivalent" results. The study demonstrates that where differences exist, the InnoSpire Go either performs comparably or better, particularly in delivering a higher total respirable dose or having smaller particle sizes.
