Title:
DIALYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/017214
Kind Code:
A1
Abstract:
When washing a dialysis fluid circuit (4) after dialysis, after first replacing the dialysis fluid inside the dialysis fluid circuit (4) with washing fluid, both on-off valves (V101, V102) are closed. Next, by opening the on-off valve (V12) while circulating the washing fluid using pumps (P1, P4) and heating with a heater (H1), the inside of the dialysis fluid circuit (4) is washed. A deaeration tank (31) is provided on the downstream side of the pump (P1). Air bubbles generated from the hot washing fluid are removed in the deaeration tank (31) and then, passing through a deaeration passage (32), are discharged into a gas storage tank (48). The invention is capable of reliably keeping the pumps (P1, P4) from becoming inoperable due to air bubbles generated from the washing fluid.
