Techniques for dialysis based on relative blood volume
Summary
USPTO granted patent US12594366B2 to Fresenius Medical Care Holdings covering systems and methods for performing dialysis using relative blood volume (RBV)-based ultrafiltration control. The patent includes population-based patient outcome data to determine target RBV ranges and controls UF pumps to maintain patient RBV within target ranges during treatment. The patent contains 12 claims and was assigned CPC classifications in medical devices and health informatics.
What changed
USPTO issued patent grant US12594366B2 to Fresenius Medical Care Holdings for dialysis technology utilizing relative blood volume (RBV) monitoring for ultrafiltration control. The patent covers methods for receiving population-based dialysis outcome data to establish target RBV ranges, monitoring patient RBV values during treatment, and controlling UF pumps to maintain RBV within specified targets. The invention addresses hemodialysis and related CPC classifications spanning medical device technology (A61M) and health informatics (G16H).
For Fresenius competitors and medical device manufacturers, this patent establishes intellectual property boundaries around RBV-based dialysis control technology. Healthcare providers and dialysis clinics should be aware that Fresenius now holds exclusive rights to these specific methods. The patent filing date of September 18, 2019 establishes Fresenius's priority position in this technology space for the dialysis equipment market.

Abstract
Systems, methods, and/or apparatuses may be operative to perform a dialysis process using RBV-based UF control. Embodiments may include methods operative to receive RBV target information comprising population-based dialysis data of real patient outcomes of a patient population associated with the patient, determine an RBV value of a patient during the dialysis process, and determine UF information to control a UF pump of the dialysis device to maintain the RBV value within a target RBV range defined by the RBV target information. Other embodiments are described.
