Daxor announced that the United States Patent and Trademark Office, or 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 monitoring technologies-including non-invasive optical sensors like photo-plethysmography 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.
