Diabetes meter question?

I am doing a project for school where we design a new device for people with diabetes. This would include a finger prick, a test strip, a blood/glucose meter, and maybe a insulin catheter. My friend, who has type 1 diabetes says that the whole process for taking blood, testing it, and adjusting his insulin intake can be a cumbersome project. Does anyone who maybe has diabetes have any ideas that would make this easier?
