The dictionary defines a tourniquet as a surgical device for arresting / stopping haemorrhage by compression of a blood vessel.
Meaning could be adapted a couple of ways:
(Surgical) Cloth or band tightened around a part of the body (like the arm) to stop blood flow temporarily.
(Religious) What Christ offers to anyone who comes to Him - Psalm 147:3 says that, "He heals the broken-hearted and binds up their wounds".

You choose your own meaning.

One of the best heavy metal bands ever. By the way, they are not grind/grundge... the first 3 records were thrash, the 4th one was hard rock and they went back to play heavy stuff in the 21st century.
I can't way for a new Tourniquet album!
