Abstract
A method for operating a portable dialysis device, comprising the following steps: continuously and alternately filling and emptying a hydraulic chamber with hydraulic fluid by a pump, wherein upon filling the hydraulic chamber, an at least partially flexible delivery membrane is moved towards a blood chamber adjoining the hydraulic chamber, in which blood is received, and wherein the blood flows tangentially along an inner wall of the blood chamber through an inlet side, whereby the blood chamber is compressed to eject the blood, and enhancing a return flow of the blood from the blood chamber while avoiding dead points in the flow in the blood chamber, and wherein upon emptying the hydraulic chamber, the delivery membrane is moved away from the blood chamber so that the blood chamber expands to receive the blood, so that a continuous, alternate compression and expansion of the blood chamber by the delivery membrane occurs, such that a continuous uninterrupted exchange of the blood in the blood chamber is performed while avoiding the formation of thrombi.
