Validation of Safety and Performance of Three EDDIS Breath-Activated Portable Inhalation Systems

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.
