Title: CONTROL UNIT FOR BLOOD DETECTION IN A DIALYSIS FLUID DISCHARGE LINE OF A BLOOD TREATMENT DEVICE, AND BLOOD TREATMENT DEVICE
Abstract:
The invention relates to a control unit (30) for detecting an exceedance of a first limit value (G1) of a first blood concentration (B1) in a first segment (17a) of a dialysis fluid discharge line (17) downstream of a dialysis fluid chamber (7) of a dialyzer (4) of a blood treatment device and upstream of a point of intersection (110), at which a bypass line (100) bypassing the dialyzer (4) terminates into the dialysis fluid discharge line (17), wherein upstream of the dialysis fluid chamber (7), the bypass line (100) branches off a dialysis fluid supply line (15), which is suited to supply the dialysis fluid chamber (7) with dialysis fluid from a dialysis fluid source (16).
