Daxor Corporation Receives U.S. Patent for Breakthrough Remote Blood Volume Monitor

New Technology Expands Daxor’s Diagnostic Capabilities to Enable Continuous, Remote Tracking of Blood Volume Status Using Wearable Sensors, Enhancing Care for Heart Failure, Syncope, Anemia, and Polycythemia

OAK RIDGE, TN, June 02, 2026 (GLOBE NEWSWIRE) -- Daxor Corporation (Nasdaq: DXR), the global leader in blood volume measurement technology, today announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 12,635,917 B2, titled “Remote Blood Volume Monitor.”

The newly issued patent covers innovative systems and methods for the ongoing and remote monitoring of a patient’s absolute blood volume status after an initial baseline measurement. By integrating subsequent hematocrit (Hct) monitoring technologies—including non-invasive optical sensors like photo-plethysmography (PPG) embedded in smartwatches or other wearable devices—with Daxor’s advanced blood volume analysis algorithms, the system provides real-time updates on a patient’s total blood volume, plasma volume, and red cell volume without the need for repeated tracer injections.

"This patent represents a major leap forward in personalized, remote patient care," said Michael Feldschuh, President and CEO of Daxor Corporation. "By bridging our gold-standard baseline blood volume analysis with widely accessible remote and wearable sensor technology, we are transitioning blood volume management from an episodic hospital-based procedure to an ongoing, proactive treatment paradigm. This is highly transformative for the millions of patients managing chronic fluid-related conditions such as heart failure, where early detection of decompensation can significantly reduce readmissions and improve survival."

The patented system is uniquely designed to provide patient-specific treatment guidance and predictive alerts. It utilizes sophisticated algorithms to automatically calculate volume deviations and trigger clinical notifications when a patient's fluid or red cell levels cross customized physiological thresholds. This early-warning capability is tailored to guide clinical interventions for a variety of critical conditions, including volume overload in heart failure, hypovolemia in syncope, red blood cell deficits in anemia, and red blood cell excess in polycythemia.

Jonathan Feldschuh, Chief Scientific Officer, added, "Historically, clinicians have lacked an accurate way to track absolute blood volume shifts on a continuous basis. This system solves that crucial problem by using a single, highly precise absolute baseline measurement to anchor subsequent continuous non-invasive measurements. By doing so, we ensure that patients and doctors have accurate, actionable data regarding internal fluid balances, wherever they are."

In addition to standalone remote monitoring, the patented technology allows for integration with other patient monitoring systems—such as blood pressure, pulse, glucose, and blood gas monitors—to provide euvolemically-corrected data for a more comprehensive physiological overview.
