    • An evertable tube 70 having a lumen 8 therethrough, an inflation port 71 for inflating the tube, and a self-closing valve at the inflation port. The tube 70 has an inflation port 71 for inflating the tube 70 to grip a member, such as a probe, in the lumen 8. Advancement of the member, for example through a colon, will then cause eversion of the tube 70. In this case the inflation port 71 is provided in the form of an aperture in the outer wall 2 of the tube 70. The valve comprises a sheath 72 extending from the port along a wall of the tube. The sheath 72 may be fixed to the wall of the tube 70 by any suitable means, such as by adhesive bonding. The sheath 72 may alternatively be integrally formed with the wall of the tube 70. The sheath 72 extends from the inflation port 71 along the wall of the tube 70 parallel to the longitudinal axis of the tube 70 to an open end 76 of the sheath 72.
    • 具有通过其的内腔8的可翻转管70,用于使管膨胀的充气口71和在充气口处的自动关闭阀。 管70具有充气端口71,用于使管70膨胀以将诸如探针的构件夹在内腔8中。构件例如通过冒号的前进将导致管70的外翻。在此 充气端口71以管70的外壁2中的孔的形式提供。阀包括从管的壁沿着端口延伸的护套72。 护套72可以通过任何合适的方式,例如通过粘合剂粘合固定在管70的壁上。 护套72可替代地与管70的壁一体形成。护套72沿着平行于管70的纵向轴线的管70的壁从膨胀端口71延伸到护套72的开口端76 。
