The World’s Friendliest Injection Device

Genotropin is a man-made human growth hormone used to treat children and adults with growth hormone deficiencies. In 1991, Pfizer (then Pharmacia) decided to redevelop its existing injection device in order to meet new regulations and user needs. Pfizer and Ergonomidesign started off their collaboration by conducting a study that showed how differently patients approached and used injection devices depending on age group, country, culture and tradition. 

The conclusions of the study were used in the subsequent design process. After several prototypes and user tests, Pfizer and Ergonomidesign had jointly developed an injection device that was functionally and aesthetically superior. The integrated needle guard hided the needle and increased stability during injection. The digital display and colour-coded buttons made it easier to set and inject accurate doses. The choice of shapes, colours and materials gave the device a warm, friendly identity.

However, one problem remained. Understandably, many children have a hard time to accept the fact that they may have to take daily injections for the rest of their lives. Would it be possible to design a device that could reduce anxiety by creating an emotional bond to the user? Ergonomidesign’s solution was to enable the user to personalise the device with the aid of exchangeable plates (similar to mobile phones) and a hole for attaching mascots, pendants and trinkets (especially important in Japan). The plates come in many different colours, patterns and themes; one version is transparent, letting the user insert photographs or drawings.
