If you’ve ever had your blood drawn, you know that while it’s not necessarily a pleasant experience, but it’s not so bad, either. A little pin-prick, a few vials of blood and an Oreo cookie later and it’s all over.

That is unless they can’t find a vein, or have to stick you more than once, or one of any other issues that can crop up. If only there was some way to find your vein easily, have a Google map of the arm or something like that.

Well now there is. A new product from Evena Medical allows the phlebotomist to see the blood flowing right beneath the skin. It’s pretty remarkable, a little creepy, and another example of some nifty medical technology. Watch the video below and be amazed.
