Why is my BTA so stretched?

They sure are. Initially I was getting artificial heart attacks from different states it was going through but the stretched part looks very weird and haven't been able to find anything online. I have two separate pumps alternating flow at 30mins and even when it is not getting blasted with flow, it stays in this deformed way. Weird creature! As long as it is not in trouble, I am not concerned.
