Abstract:
A method of reversing a blood flow between a patient access and a dialyzer, the patient access having an upstream port and a downstream port, the dialyzer having an inlet and an outlet, comprising:(a) fluidly connecting a first port of a deformable chamber to the upstream port;(b) fluidly connecting a second port of the deformable chamber to the dialyzer inlet, the second port adjacent the first port;(c) fluidly connecting a third port of the deformable chamber to the downstream port, the second port being immediately intermediate the first port and the third port;(d) fluidly connecting a fourth port of the deformable chamber to the dialyzer outlet port, the fourth port being immediately intermediate the first port and the third port; and(e) selectively deforming the chamber along a first clamp line to contact opposing interior surfaces of the chamber, the contacting interior surfaces along the first clamp line precluding fluid flow in the chamber from the first and second ports to the third and fourth ports.
