Auto-Injector usability study: how many testers does it take to spot the flaws?
NCT ID NCT03808246
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how many people are needed to find usability errors in the Zeneo® auto-injector pen, a device used for severe allergic reactions. 60 healthy volunteers used a demo version during a simulated anaphylactic shock. The goal was to improve device design by catching mistakes before real patients use it.
