Teleport Trigger type spell?

[kalos72]

So my group is looking at the Drow insignia and wants to make their own of course.

They are asking about a spell that would teleport the wearer and all his gear to a predetermined location should they fall under like 5% HP or something...

I cant find a spell to do that, any book 3.5ish is preferred. Would a "no choice" teleport away from battle be smart...or perhaps just a teleport to group/safety or something?

Feedback?
