As a person who actually changed insulins to get a 'Memoir' pen with a dose memory this simple solution to part of the problem ("Hang on... have I injected or not...") appeals to me. Since having the Memoir I know I often check to confirm the exact timing of doses. Sadly however the Memoir is currently unavailable and Novo Nordisk's Novopen Echo is still not scheduled for release in the UK. So at the moment there is just no MDI device that records the timings of your injections.
Enter 'Timesulin' an ingenious digital timer which can be used as a replacement cap for your existing insulin pen (currently only Kwikpen®, Flexpen®, Solostar® are supported). When you remove the pen cap to inject the timer resets to zero and begins to count up again. So by looking at the pen lid you can tell how many hours (or minutes) have passed since you last injected. Cleverly if you pop the pen lid off to check how much insulin is still in the cartridge (or whatever) the timer keeps counting. It only resets the timer if the cap stays off the pen for more than 8 seconds.
At the time of writing the Timesulin caps themselves are 'in the final phases of production' and are due to be available for purchase from mid-November 2011.

Would be very interested to hear from anyone who gets hold of one, and whether they found them useful. Leave us a comment below...
