Abstract
A two-bag system (2) for peritoneal dialysis comprises a female connector piece (4) which is connected via a tube (28) to a peritoneal catheter. The female connector piece (4) can be connected to a male connector piece (6) to permit introduction of fresh dialysis solution from a full bag (12) into the peritoneal cavity. For receiving used dialysis solution or for receiving flushing solution accumulating prior to the dialysis operation, an empty bag (38) is provided which is connected via a further tube (36) to the male connector piece (6). The female connector piece (4) comprises a shutoff member (32) which in a predetermined connection state of the connector is opened by a central tube section (16) of the male connector piece (6). By arranging a second connection (34) on the male connector piece (6) in cooperation with the closure member (32) and a radial opening (23) in the central tube section (16) a fluid connection is possible to the two bags ( 12, 38) and the peritoneal cavity.
