Device for supporting insertion of medical instrument into human body

摘要

A tubular member 2 is formed of a resin material so as to have an inner passageway 2 . A thin plate is shaped into a spiral along the perimeter of the tubular member 2 to form a reinforcement member 3 . The reinforcement member 3 is buried in a peripheral wall 2 a of the tubular member 2 . The tubular member 2 and the reinforcement member 3 have curved shapes conformable to the shape of the pharynx 100 . The tubular member 2 and the reinforcement member 3 are inserted from the oral cavity 102 into the pharynx 100 and retained there. A medical instrument is guided to the esophagus 103 through an inner passageway 2 b of the tubular member 2.
