Method of peritoneal dialysis using a tube set
First Claim
Patent Images
1. A method of performing peritoneal dialysis comprising the steps of:
- providing a tube set including a unitary tubular member having at least one supply lumen and at least one discharge lumen and partition means therebetween;
transporting fresh dialysis solution through said at least one supply lumen of said tube set, into a connector arranged at a second end of said unitary tubular member, said connector having a common chamber for fluid communication with said at least one supply lumen and said at least one discharge lumen, and into a patient through a peritoneal catheter arranged in said patient;
removing spend dialysis solution from the patient by transporting said spend dialysis solution through said common chamber of said connector into said at least one discharge lumen of said unitary tubular member so that said at least one supply lumen and said at least one discharge lumen simultaneously transport said fresh dialysis solution and said spend dialysis solution in opposite directions of flow respectively, thereby transferring heat between said fresh dialysis solution and said spend dialysis solution through said partition; and
discharging said spend dialysis solution by transporting it from said at least one discharge lumen to a discharge location.

Abstract
A method of using tube sets for peritoneal dialysis. The Tube sets for peritoneal dialysis include a unitary tubular member having a number of lumens, including at least two lumens, the first for supplying fresh dialysis solution to the patient, and the second for discharging spent dialysis solution from the patient, such that the unitary tubular member can both supply the fresh dialysis solution and discharge the spent dialysis solution and at the same time heat can be transferred therebetween.
