Method for removing blood from an extracorporeal blood circuit after completing a blood treatment session, a control and conditioning unit for performing the method, and a treatment device

摘要

The present invention relates to a method for removing blood and / or blood mixtures from an extracorporeal blood circuit (1) having a blood filter (19) used for blood treatment of a patient after completing a blood treatment session. Here, the blood filter (19) comprises a blood chamber (19a) and a spent dialysate chamber (19b) with a membrane disposed therebetween. The blood chamber (19a) leads to the arterial blood line (9) leading to the blood chamber (19a) and the venous blood line (23) away from the blood chamber (19a) and to the dialysate chamber (19b) for blood processing purposes. It is connected to the dialysate inlet line (31a) and the dialysate outlet line (31b) away from the dialysate chamber (19b). The method introduces a replacement fluid into the arterial blood line (9) and eliminates the pressure difference with a lower pressure in the spent dialysate chamber (19b) and a higher pressure in the blood chamber (19a). Moving the blood and / or blood mixture from the blood chamber (19a) by generating within. [Selection] Figure 2
