WEARABLE MONITORING DEVICES HAVING SENSORS AND LIGHT GUIDES

摘要

A monitoring device includes a housing configured to be attached to a body of a subject. An optical emitter, optical detector, and sensor for measuring motion noise are located within the housing. Light transmissive material is in optical communication with the optical emitter and detector and is configured to deliver light from the optical emitter to one or more locations of the body of the subject and to collect light external to the housing and deliver the collected light to the detector. A signal processor is configured to receive and process signals produced by the optical detector and the motion noise sensor, and to remove noise from the signals produced by the optical detector. The signal processor may generate physiological parameters for the subject such as heart rate, blood flow, blood pressure, VO2max, heart rate variability, respiration rate, and blood gas/analyte level.

1. A monitoring device, comprising:
a housing configured to be attached to a body of a subject; at least one optical emitter within the housing; at least one optical detector within the housing; at least one sensor for measuring motion noise within the housing; and light transmissive material in optical communication with the at least one optical emitter and the at least one optical detector, wherein the light transmissive material delivers light from the at least one optical emitter to one or more locations of the body of the subject and collects light external to the housing and delivers the collected light to the at least one optical detector.
