ABSTRACT:
A peritoneal dialysis apparatus comprises a single lumen catheter through which in an intermittently operated circuit dialysis liquid is pumped from the peritoneal cavity of a patient and is then moved along in contact with a dialysis membrane, at which not only mass exchange but furthermore the withdrawal of ultrafiltrate is able to take place. On this membrane of the dialyzer a secondary dialysis takes place so that on the other side of the membrane dialysis liquid with an osmotically acting substance is moved in single-pass mode. Preferably the peritoneal dialysis circuit is made up of two dialyzers so placed that the one outlet of the first one is joined with a conventional dialysis apparatus and the outlet of the second dialyzer is joined with the catheter in the patient.
