摘要：
A vacuum drainage system for unclogging a clogged drain comprises a source of vacuum, a hose having a proximal end portion and a distal end portion, the proximal end portion of the hose being connected to the source of vacuum when the system is in use, and a drain clean-out device being received on the distal end portion of the hose when the system is in use. The drain clean-out device comprises a hollow tubular structure, a sealing member receiving portion located on the exterior surface of the hollow tubular structure at the first end portion of the structure, and a sealing member mountable on the sealing member receiving portion for creating a seal between the sealing member and the exterior service of the structure and between the sealing member and a clogged drain when the hollow tubular structure, with the sealing member mounted thereon, is positioned over a clogged drain, with the sealing member being in contact with an entrance to the drain or with a surface surrounding the entrance to the drain.
