Abstract
A connector (2) for peritoneal dialysis comprises a female connector piece (4) and a male connector piece (6). The male connector piece comprises a central tube section (22) whose diameter tapers at a step (26). Furthermore, the female connector piece (4) comprises a valve means (52) which consists of an annular seal (54) and a valve plate (58) which is pressed by means of a pressure spring (60) against the sealing ring (54). On connection of the female connector piece (4) with the male connector piece (6) at least one pin (46) on the male connector piece engages in a guide groove (48) which is formed in a sleeve (10) in which the female connector piece (4) is provided. The guide groove (48) comprises a staircase or step-like form so that the female connector piece (4) can assume relatively to the male connector piece (6) three defined connection states, said three connection states effecting that the tube section ( 22) in cooperation with the valve means (52) releases or blocks fluid passages between a first connection (18), a second connection (32) and a third connection (36). The third connection (36) serves for connecting an empty bag for the used dialysis solution and is arran…
