Claim:
A valve unit for regulating a flow of urine, said valve unit comprising an inlet portion and an outlet portion separated from each other by a slide valve, said slide valve comprising a valve housing formed as a female part in direct communication with the inlet portion and the outlet portion, and a valve body formed as a male part being axially displaceable in parallel and in liquid-proof contact with the female part, said male part being configured for assuming two positions, a closing position and an open position, in which closing position a portion of the male part is outside the female part; that, in the closing position and in the area where the inlet portion and the outlet portion connect to the female part, outer faces of the male part provide a liquid-proof blocking between the inlet portion and the outlet portion; that, in the open position, the male part allows liquid passage between said inlet portion and said outlet portion by means of a communication part; wherein said female part comprises a tubular member open at both ends and having a tubular wall extending along the entire length of said male part in said open position to completely enclose said valve body in said open position with no portion of said valve body projecting from said valve housing, for deterring displacement of said valve body to said closed position.
