Brief Summary
This is a crossover study to evaluate real-time performance, airflow control, user-device interaction, and safety systems of three portable inhalation systems from the EDDIS platform. The formulation is non-pharmacological and inert. Each volunteer will use all three devices in random order. Primary endpoints focus on gas dynamics, inhalation recording accuracy, device integrity, and user tolerability.

Study Arms (3)
Healthy Volunteers - VMT First
EXPERIMENTALAll participants receive the VMT device first, followed by the Atomizer and Ultrasonic devices in a randomized crossover sequence using a non-active saline aerosol with chitosan nanoparticles. Device performance parameters and user tolerability will be recorded
Healthy Volunteers - Atomizer First
EXPERIMENTALAll participants receive the Atomizer device first, followed by the VMT and Ultrasonic devices in a randomized crossover sequence using a non-active saline aerosol with chitosan nanoparticles. Device performance parameters and user tolerability will be recorded
Healthy Volunteers - Ultrasonic First
EXPERIMENTALAll participants receive the Ultrasonic device first, followed by the VMT and Atomizer devices in a randomized crossover sequence using a non-active saline aerosol with chitosan nanoparticles. Device performance parameters and user tolerability will be recorded
Interventions
A set of three single-use, disposable, closely matched and uniform in size, breath-actuated, digitally monitored portable inhalation devices designed for precision aerosol delivery. Devices include a vibrating mesh (VMT), an atomizer-based unit (ATM), and an ultrasonic micro-vibration unit (ULT). Each system records inhalation parameters and connects via Bluetooth to a mobile application for real-time feedback and logging. Used to assess technical performance, gas dynamics, and digital control functions using a non-active NaCl-based aerosol with chitosan nanoparticles.
