What changed

USPTO granted patent US12588820B2 to OMNI MEDSCI, INC. for a wearable device that measures physiological parameters including pulse rate and blood flow. The device uses one or more biosensors, LED light sources, lenses for directing light toward tissue with blood vessels, and a detection system for receiving reflected tissue light. The measurement technique is differential, and artificial intelligence may be used for signal analysis and decision-making. Signal-to-noise ratio improvements are achieved through synchronization of detection to the light source.

This is a routine patent grant notification, not a regulatory requirement or compliance obligation. No action is required from medical device manufacturers, healthcare providers, or other parties. The patent grants exclusive intellectual property rights to the assignee but does not impose new regulatory requirements on the industry.

Abstract

A wearable device to measure a user's physiological parameters comprising one or more biosensors, as well as a light source comprising light emitting diodes, lenses for directing light towards tissue of the user comprising blood vessels, and a detection system receiving reflected tissue light. The physiological parameters, for example hypertension, are measured with a differential measurement. For example, the physiological parameters may be associated with pulse rate and blood flow. The output signal is associated with the physiological parameters, and artificial intelligence may be used in making decisions regarding the output signal. Signal-to-noise ratio of the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity, and detecting a change. The wearable device is configured to determine that is being worn by the user and may be configured to communicate with a smartphone or tablet.
