What changed

This document is a publication of a new patent application filed with the USPTO, specifically application US20260083329A1, titled 'REAL TIME OPTO-PHYSIOLOGICAL MONITORING METHOD AND SYSTEM'. The application details a method for monitoring a subject using an opto-physiological sensor system integrated into a wearable device. It involves modeling optical properties of body tissue, obtaining physiological and physical variable data from the wearable device, and using this information to determine and correct physiological property values.

As this is a patent application publication, it does not impose new regulatory obligations or compliance deadlines on regulated entities. However, it may be of interest to medical device manufacturers and healthcare technology developers involved in wearable sensor technology and physiological monitoring. Compliance officers in these sectors should be aware of emerging patented technologies that could influence future product development and regulatory landscapes.

Abstract

A method of monitoring a subject with an opto-physiological sensor system is described herein. The method comprises obtaining a model of the optical properties of at least one body tissue type to be monitored, wherein the model of the optical properties comprises a definition of static (DC) and dynamic (AC) components of transmitted optical power and a definition of a source-detector separation related to a normalised path length for an illumination source of the opto-physiological sensor: obtaining an indication of at least one physiological property of the subject from a wearable device worn by the subject: obtaining an indication of at least one physical variable from the wearable device worn by the subject; determining, using the opto-physiological model, how the at least one physical variable affects the at least one physiological property; and determining a corrected value for the physiological property based on the determination of how the at least one physical variable affects the at least one physiological property.
