摘要：
A cuffed tube (1) is equipped with a tube (10) that can be inserted into the inside of a tubular tissue in vivo and a cuff (12) which is provided on the outer peripheral surface of the tube (10) and expands by introduction of fluid into the gap with the outer peripheral surface of the tube (10). The cuff (12) has: a cuff main body member (120) that has a cylindrical shape, said member (120) covering the entire circumference of a partial region in the extending direction of the tube (10), and said member (120) being fixed to predetermined parts in the extending direction of the tube (10) at both end parts in the axial direction of the tube； and and has convex members (121-123) that projects toward the inside of the cuff main body member (120) with respect to an intermediate part in the axial direction of the tube on the inner peripheral surface of the cuff main body member (120), said convex members (121-123) being joined so that recesses and projections appear on the outer peripheral surface of the cuff main body member (120) when the cuff (12) is inflated. The part of the cuff (12) where irregularities appear on the outer peripheral surface of the cuff main body member (120) when inflated serves as a nonslip portion against the tubular tissue.La présente invention concerne un tube à manchon (1) muni d'un tube (10) qui peut être inséré à l'intérieur d'un tissu tubulaire in vivo et d'un manchon (12) qui est disposé sur la surface périphérique externe du tube (10) et qui s'étend par introduction de liquide dans l'espace avec la surface périphérique externe du tube (10). Le manchon (12) présente : un élément corps principal de manchon (120) qui présente une forme cylindrique, ledit élément (120) recouvrant la circonférence entière d'une région partielle dans le sens d'extension du tube (10), et ledit élément (120) étant fixé à des parties prédéterminées dans le sens d'extension du tube (10) aux deux parties d'extrémité dans le sens axial du tube ； et présente des éléme
