ANALYSIS OF DIALYSATE PROFILE, CONTROLLED BY UV-MONITORING Russian patent published in 2015 - IPC A61M1/16 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to efferent therapy, and can be used in carrying out dialysis procedures. Claimed is a blood-processing device, which contains a blood processing unit, a UV measuring device and a central processing unit. Also claimed is a method for the optimisation of dialysate consumption by means of the said device, where the selection of the operation mode and the smallest admissible value of the dialysis effectiveness parameter are preliminarily realised in the blood processing unit. Current measured values of blood and dialysate flows in the blood processing unit are determined. Variation of the solution flow for dialysis in the blood processing unit is carried out during the dialysis session. After that, the UV absorption of at least one uremic substance in an output dialysate flow or in extracorporal blood circulation of the blood processing unit is measured. The measured values of UV absorption and the current measured values of the blood and dialysate flow are transmitted into the central processing unit. A flow of the solution for dialysis and/or blood, optimised as to the dyalysate consumption, and/or a relative ratio of the two flows within the range Q_D/Q_B, or a ratio of the volume passing ability for dialysate and blood within the limits of V_D/V_B range are determined. The change of the flow is displayed in the central processing unit and/or automatic re-correction in accordance with the change is performed. After that, the stages are repeated.

EFFECT: inventions provide lower consumption of the dialysis solution without an impairment of purification due to complete use of the entire filter potential.
