Connector for peritoneal dialysis

A continual ambulant peritoneal dialysis tube connection device comprising:

• a male connector piece having a central tube section joined to and surrounded by a protective sleeve, a receiving region between said central tube and protective sleeve, a first connection means for connecting a first dialysis solution bag, and a third connection means for connecting a second dialysis solution bag;
• a female connector piece having a valve means, an introduction portion, a second connection means for connecting a peritoneal catheter, and an annular seal;
• said valve means having a valve plate for providing a fluid barrier in its uncoupled state prohibiting the flow of fluids through its elongated axial direction;
• said introduction portion forming a liquid-tight seal between said protective sleeve on said male connector piece and said female connector piece after being inserted into said receiving region.;
• said first connection means being in fluid communication with said central tube section;
• said valve means cooperating with said central tube section and the inserted position of said female connector within said protective sleeve providing for selective fluid communication between any two of said first connection means, said second connection means, and said third connection means;
• said central tube section having a mouth opening forming a fluid-tight seal with said valve plate when said mouth opening contacts said valve plate,
• whereby said male connector piece (6) in a first coupling position with said female connector piece (4) in fluid-tight manner with said annular seal (66) effects a first fluid passage from said first connection means (18) to said third connection means (36), when in a second coupling position by said central tube section (22) of said male connector piece (6) interacting with said valve means (52) within said female connector piece (4) opens said valve, said mouth opening (24) of said central section (22) having a fluid-tight sealing manner on said valve plate (58) and said front portion (30) passing through an opening (57) of said annular seal (56) to effect a second fluid passage from said second connection means (32) to said third connection means (36), and when in a third coupling position said main portion (28) of said central tube section (22) of said male connector piece (6) forming a fluid-tight seal with said annular seal (56) of said female connector piece (4) and said valve plate (58) being tilted from said mouth opening (24) of said central tube section (22) forming a third fluid passage from said first connection means (18) to said second connection means (32), each of the coupling positions are predetermined and lockable by a connecting means.
