There's already a bevy of devices out there designed to keep track and manage one's diabetes and glucose levels, but Eli Lilly's innocuous pen-like injector looks to make the process of taking insulin a bit less invasive. The Huma-Pen Memoir resembles your average ink pen and shouldn't look too out of place holding it down in your tee's front pocket, but whenever you need a shot of insulin, it conveniently turns into an injector thanks to the hidden hypodermic needle encased within. The device also "allows the user to dial the amount of insulin they need to take," and keeps the dosage, date, and time of the previous 16 shots in order to keep diabetics from overdosing. Users should be able to utilize the same pen for "around three years," and after a needle is used, another is inserted and ready to go at the owners request. A few lucky participants have already received their pen here in the US, and while this nifty invention has been available across Europe for some time now, it will officially hit American retail shelves next week for around $45.
