Ilmater Magic Item

I think it may be from 2nd or 3rd edition but I remember a magic item something like wraps of Ilmater  or Bandages of Ilmater.

I will have a think and work on something like Bandages of Ilmater any thoughts or ideas welcome.

From what I remember, because i can't find the official item, it let someone heal another person as long as they also took half the hitpoints healed from themselves. It rounded, but i don't know if it was up or down. I think it had touch range.

That would be hard to balance around, because you could turn your fighter or Barbarian into your biggest spot healer. Wouldn't be terrible, as it wouldn't fully step on a paladin's toes, but I could see it causing tension. 
At least it might get people to spend hit-dice during short rest more aften.
