Deflation tube to be inserted into intestines after endoscopic check, comprises perforated walls

摘要

The intestine to be checked has to be slightly inflated beforehand in order to enter the endoscopic device. A substantial amount of the gaseous substance remains inside the body after the procedure leading to very painful spasmodic contractions because the intestine is tightly closed by the sphincter. The deflation tube is more than twice as long as the endoscopic device and inserted at the start of the retraction. Two thirds of the wall are perforated, preventing the tube from clinging. The sphincter is kept slightly relaxed temporarily in order to facilitate a gradual release.
