A Wangensteen suction apparatus
is a modified siphon that maintains constant negative pressure.
Used on a duodenal tube, it relieves gastric and intestinal distention caused
by the retention of fluid.[1] It was first created by Dr. Owen H. Wangensteen (1898–1981),
the Chief of Surgery at the University of Minnesota.[2] His novel approach to the most fatal cause of death during
gastrointestinal surgery has since been credited with saving more than one
hundred thousand lives.[3]
