US12605079B2 Physiological Parameter Measurement System, Sonion Nederland
Summary
The USPTO granted Patent US12605079B2 to Sonion Nederland B.V. for a system and method measuring physiological parameters of blood-perfused tissue using dual radiation sensors—one sensor measures blood volume via radiation absorption, while the second measures blood flow speed via Doppler shift—with a controller determining the physiological parameter from both data streams. The patent contains 13 claims and covers CPC classifications in the A61B medical diagnosis category.
What changed
The USPTO issued Patent US12605079B2 to Sonion Nederland B.V., inventor Peter Christiaan Post, covering a system and method for determining physiological parameters of blood-perfused tissue. The system uses a first sensor measuring radiation absorption to determine blood amount and a second sensor measuring Doppler shift to determine blood flow speed, with a controller combining both data streams. Affected parties include medical device manufacturers developing similar physiological monitoring technologies who should review this patent for potential licensing needs or design-around considerations.

Abstract
A system and a method for determining a physiological parameter of a body comprising blood perfused tissue, the system comprising a first sensor configured to receive first radiation from the blood perfused tissue and, based on the received first radiation, provide first information relating to an amount of blood in the tissue, such as from an absorption of the first radiation in the tissue, a second sensor configured to receive second radiation from the blood perfused tissue and, based on the received second radiation, provide second information relating to a speed of blood in the tissue, such as from Doppler shift of the second radiation, a controller configured to determine the physiological parameter from the first information and the second information.
