Abstract
A peritoneal dialysis ('PD') system includes a housing; a PD fluid pump housed by the housing; a filter set including a filter housing and a hydrophilic filter membrane dividing an upstream chamber from a downstream chamber; a dual lumen patient line including a fresh PD fluid lumen in fluid communication with the upstream chamber and a used PD fluid lumen in fluid communication with the downstream chamber; a pressure sensor positioned and arranged to provide a pressure sensor output indicative of pressure in the downstream chamber of the filter housing; and a control unit configured to perform a pressure integrity test on the hydrophilic filter membrane by monitoring the pressure sensor output over a period of time, the pressure sensor output indicative of a negative pressure created in the downstream chamber by the PD fluid pump. A pressure drop test for evaluating the filter membrane is also disclosed.
