HumaPen Memoir: a novel insulin-injecting pen with a dose-memory feature.

Optimizing glycemic control may help to reduce the risks of diabetes complications, but it is often difficult to achieve, partly owing to poor treatment adherence. One barrier to adherence is forgetfulness. The HumaPen Memoir pen is the only electronic reusable insulin pen with a multiple-dose memory feature. This enables the device to store information regarding dates and times of the previous 16 doses of insulin, including priming doses. The pen has a digital display and a two-way dial to minimize waste of insulin. The digital display facilitates accurate dose selection. Both patients and healthcare providers rate as important the pen's ability to confirm administered doses and times, its overall ease of injection and display readability, and its minimal waste when adjusting dose settings.
