The diagnosis of diabetes can be a scary piece of news to receive. However, for many sufferers the only difficulty they will face is remembering to inject themselves with insulin at the correct intervals three times a day. John Sjölund was diagnosed with Type 1 diabetes at the age of three, and was very aware of how easy it was to lose track of his injections. This memory lapse can be life-threatening and John wanted to invent a simple device that would help people keep track of their daily dosages. He came up with the idea for Timesulin, a replacement cap for an insulin pen that also has a display which shows how much time has passed since the last injection.
