| 摘要 |
The invention relates to an apparatus for conducting liquid, comprising a tubular conduit (7) comprising at least two separate lumens (A, B) each having a first and a second end, where the first ends are adapted for connection to an inlet opening (9) of a receptacle (10); a coupling element (13) with a chamber (103) whereto the at least two lumens are connected such that a communication between the two lumens is provided through the chamber, and where the chamber has an inlet opening (2) to which a liquid source can be connected. The invention is characterized in that the coupling element comprises a one-way valve (6) allowing fluid to flow from the source of liquid through the inlet opening and into the chamber, but prevents that liquid flows from the chamber and out through the inlet opening, which makes possible complete emptying of the tubular conduit for liquid and prevents retrograde flow of liquid towards the liquid source.
