'Kleenex' is not so universal though (I don't call tissue that). I think the red cross symbol pretty much is. What other symbol would you use for medicine/medical? Just look at any first-aid box, and it has a red cross. Even nurse dress-up costumes. Of course if I tried to start an NGO using the symbol, I would rightly be sued. But using it generically, in games for med-paks or whatever, etc, seems fine to me.
