Abstract
A method for monitoring conveyance of fluid in a device for extracorporeal blood treatment, whereby fluid is conveyed by a peristaltic pump in a fluid system from a low-pressure side to a high-pressure side in that an elastically deformable fluid line positioned between the low-pressure side and the high-pressure side is deformed between a support surface and at least two squeeze elements of a rotor rotating opposite the support surface in such a way that a conveyance volume section is formed between the squeeze elements, whereby a fluid pressure value in the fluid system is detected for the conveyance volume section that is specific to the conveyance volume section, and whereby the detected conveyance-volume-specific fluid pressure value of a conveyance cycle n is compared with the detected conveyance-volume-specific fluid pressure value of a previous conveyance cycle n−x.
