MDO Article: Staying Dry: How to Limit Wet Injections in Auto-Injector Design

by Christina S

In Design Science’s most recent guest column for MedDeviceOnline, Analyst Bryon Calawa examines the challenges that researchers face when evaluating auto-injectors in usability studies.

After years of witnessing wet injections, Calawa jests that he is starting to consider "wearing goggles to my next study." He then goes on to explain that wet injections are no laughing matter. They not only result in a costly waste of medication, but in a delay of therapy, as well.

“Unlike a syringe," Bryon contends, "the premature removal of an auto-injector is unrecoverable; the entire contents of the device are expelled, uninterrupted, once the injection begins.”

For four methods that medical device designers can use to avoid these messy errors, read the full article here.
