Can't you take out a travel insurance to cover health issues?
I have been with the ADAC back in Germany and found that they have a very comprehensive offer, both for breakdown and medical cover if you chose the plus membership. But that was a while back. As for European cover, make sure that it covers Germany as well, as they are a German provider and might not include it in the European cover. I would call them to see how they deal with someone who doesn't speak German.

Good luck!
