My father has to give himself  weekly shots of vitamin B12 to deal with a condition he has called pernicious anemia. I am not entirely clear on what exactly pernicious anemia is, but I do know that if he doesn't get his shots he gets weak and lethargic. One slight problem for his weekly injection is the fact that my father also has hand tremors. Ours is not an easy family, and so his stories of his shaking hands as he attempts to stab his thigh are the topic of much laughter at the dinner table. So to atone for my tacky sense of humor I will inform my father of Bioject, a needle free injection system. "Bioject's technology works by forcing liquid medication at high speed through a tiny orifice held against the skin. This creates an ultra-fine stream of fluid that penetrates the skin, delivering medication in a fraction of a second. Bioject's systems are designed to deliver injected medications comfortably, accurately, and quickly - without the use of a needle."

Perhaps with this little gadget my father can more easily inject his vitamin B12 and not end up with jab marks all over his legs.
