Many (most, probably) do not change the lancet every time. Some will reuse it once or twice. Some change it once a day or once a week or will just keep using the same one until it gets so dull it no longer punctures the skin!

I like the Accu-Chek Multiclix. It uses drums that contain 6 lancets and works better than almost every other device I've tried. The Accu-Chex SoftClix is another good one. It uses special lancets (one at a time) so both of these might not be the best choice if you are changing it every time. I personally reuse the same lancet for months before I remember to change it. No infections ever.
