A transfigured port key in his glasses does seem possible, or some kind of explosive device hidden in the transfigured ring.
EDIT: Fawkes is also a way out here, if Harry can delay an enemy attack for several seconds
Second edit (the serious one): The ring contains some kind of binding device. This could be the blinding potion Harry used in battles, a set of flash-bang grenades, or (most likely) a seventh-year variant of the blinding potion Harry bought off a student. This countermeasure will blind the unwarded death eaters which allows Harry to immediately fall to the ground and call Fawkes. Fawkes teleports Harry out and allows escape.
I was wondering how much retroactive power we would have.
Harry would know, or be able to look up, any number of chemicals that would react very poorly to the open air. It would be exceedingly foolish to carry one on his person, transfigured, such that he would simply have to negate the tranfiguration to have a distraction or attack, but would such a thing be in our power to suggest into existence, if we thought of a sufficiently non-foolish way for Harry to carry this?

I was thinking of a transfigured portkey attached to one of his fingernails. That way even if bound he should still be able to activate it.
BUT The students were issued with portkeys in the form of toe rings and Harry got rid of his explicitly.
