KwikPen™

Lilly’s next generation pre-filled insulin pen

People with diabetes often worry about their diet, blood glucose readings and insulin injections. IDEO was charged with designing a new pre-filled, discreet insulin device to help patients deliver their insulin. Building on the successful experiences with two previous pen designs, Lilly partnered with IDEO again to design a next generation pre-filled injection pen.

Lilly sought to integrate IDEO’s engineering expertise and human centered research approach to create a design that minimized size and improved patient ease-of-use. To ensure high quality manufacturing at annual production volumes measured in millions, the team carefully analyzed more than 100 interactions between the pen’s 13 parts so final pen assembly would reliably meet fit, function, and performance requirements.

The resulting insulin injection pen called Kwikpen™ successfully hit the US market in 2008 measuring 5.7 inches long — only slightly longer than a Sharpie™ marker. The small size proved important to patients by improving discretion between doses (when carried in pocket or purse), as well as reducing the stroke length required to inject the dose. These features combined with a lower pressure to inject and clearly legible dose numbers helped Kwikpen™ better address patients’ needs.
