Apparatus and control methods for determining a distribution volume of at least one uremic substance in a dialysis patient are disclosed. The apparatus may include a dialyzer, an optional flow rate measuring system for detecting the flow rate of a dialysis fluid through the dialyzer, a dialysis fluid measuring system for detecting at least one dialysis fluid parameter that depends on the at least one substance in the dialysis fluid, and a computer for establishing a dialysis dose based on the dialysis fluid parameter and for establishing the distribution volume based on the dialysis dose taking a clearance factor and dialysis duration into account.

Apparatus and method for determining distribution volume in dialysis patient

A device for extracorporeal blood treatment is disclosed that includes a detection equipment for detecting uremic toxins in a used dialysis liquid by measuring the absorbance, the detection equipment being provided at such a position downstream the outflow of the dialysis liquid from a filter element that at least one of the following requirements is fulfilled: a) the filling volume of the fluid line and of the components starting from the outflow of the used dialysis liquid from the filter element to the detection equipment is less than or equal to 100 ml; and b) the length of the fluid line starting from the outflow of the used dialysis liquid from the filter element to the detection equipment is at most 250 cm.

Device for extracorporeal blood treatment

The invention describes an apparatus for extracorporeal blood treatment with a dialyzer which is separated by a semipermeable membrane in to a first and second chamber (), wherein the first chamber () is arrange in a dialysate pathway and the second chamber () is connectable to the blood circulation of a patient by means of a blood supply conduit () and a blood return conduit (), an inlet () for fresh dialysate, an outlet () for spent dialysate, a measuring device () arranged in the outlet (), wherein said measuring device () has at least one radiation source consisting of several light sources () for electromagnetic radiation. The invention is characterized in that the measuring device () is designed to generate substantially monochromatic electromagnetic radiation of different wavelengths, and to lead only one of these wavelength (at the same time) though the outlet () for spent dialysate, wherein at least one detector system () is provided for detection of the intensity or the absorption of the substantially monochromatic electromagnetic radiation passing through the outlet () for spent dialysate.
