Wangensteen suction
From Wikipedia, the free encyclopedia
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 Owen Harding Wangensteen (1898–1981), the Chief of Surgery at the University of Minnesota.[2][3] His novel approach to the most important cause of death during gastrointestinal surgery has since been credited with saving more than one hundred thousand lives.[4]
