ABSTRACT OF THE DISCLOSURE Kidney dialysis filters, or artificial kidneys, which contain a dialysis membrane mounted inside a housing and separating the housing into a blood side compartment and dialysate side compartment are washed for reuse by a process in which washing water is supplied to the blood side through an inlet hose, and exists through a remote, resiliently expandable and contractable outlet hose to a drain. After flushing of the blood side by water flow in this manner, the outlet is closed whilst continuing washing fluid feed, to build up fluid pressure inside the blood compartment, and then the fluid feed is interrupted. A drain in the inlet conduit is then opened to cause brief reversal of flow of fluid within the blood side, due to relaxation of the membrane and the outlet hose to relieve the fluid pressure. Then steady flow of fluid is resumed. This brief reversal of flow causes a fluid action to dislodge contaminating blood particles from the membrane and elsewhere, but without risk of depositing these blood particles in a portion of the apparatus where they could later contaminate an artificial kidney subsequently washed using the apparatus. The rate of pressure drop in the blood compartment can be measured and used to determine the extent of obstruction of the blood compartment.
