Our industrial designers worked to deliver a streamlined design involving fewer parts, saving around 240,000 components for every 10,000 devices made. The use of a simple internal mechanism also enabled the trainer to be more robust, easily withstanding repeated use.
The trainer offers a straightforward four step training experience, designed to accurately simulate delivering a real injection. Given the four-sided geometry of the actual auto-injector, we decided to print the onboard instructions on the sides of the trainer. Each side walks the user through a step, with text inverted at the crucial injection stage to ensure correct handling. Once used, the device can easily be reset by simply reversing the same steps. These design innovations resulted in a sustainable, patient-centric trainer pen that is already being used to help onboard patients.
