Apparatus and method for the determination of residual blood in a dialyzer and dialysis system

摘要

The present invention relates to a device (1) and a corresponding method for the determination of residual blood in a dialyzer (2) having a receiving device (6) which is adapted to receive a dialyzer (2), an image acquisition device (7) which is provided is set up to capture at least one image of a dialyzer (2) recorded by the recording device (6), in particular a filter (4) located in the dialyzer (2), and to generate corresponding image data having a multiplicity of pixels each having at least an intensity value, in particular a color value, is assigned, and a control device (9) which is set up to characterize a residual blood information characterizing the presence and / or the content of residual blood in the dialyzer (2) based on a statistical frequency of at least part of the intensity values in to determine the at least one image. The invention further relates to a dialysis system with such a device (1).
