YpsoMate 5.5

Ypsomed has recently announced its new autoinjector platform for larger volume liquid medications. Shore is proud to have worked on the industrial design for the YpsoMate 5.5.




With the larger 5.5mL syringe having a knock-on effect on the size of the device; we had to ensure that there would be a comfortable grip. We created a narrow section amongst the internal components to create a ‘waisted’ section acting as a natural and comfortable shape to hold. This is essential when delivering larger, higher viscosity doses as they can take significantly longer to inject.




Through extensive prototyping, we made sure that the needle cap would be an intuitive and easy interaction. Designs were tested wearing gloves that simulate the restrictions in movement that conditions such as arthritis cause, and we created a test rig to replicate worse case scenarios of the pull-off force.




Human factor studies have shown that constant feedback during injection reduces anxiety and offers reassurance to a user. Some autoinjectors are designed with a drug window and plunger position as the visual indicator that an injection is in progress, however it is sometimes covered by the hand when in use. With the rotating injection indicator positioned at the top of the YpsoMate 5.5, it means that it is less likely to be covered. It’s also mechanically linked to the syringe drive mechanism, allowing the user to see exactly what is happening during injection.
