Light-Guiding Devices and Monitoring Devices Incorporating Same

摘要

A monitoring device configured to be attached to the ear of a person includes a base, an earbud housing extending outwardly from the base that is configured to be positioned within an ear of a subject, and a cover surrounding the earbud housing. The base includes a speaker, an optical emitter, and an optical detector. The cover includes light transmissive material that is in optical communication with the optical emitter and the optical detector and serves as a light guide to deliver light from the optical emitter into the ear canal of the subject wearing the device at one or more predetermined locations and to collect light external to the earbud housing and deliver the collected light to the optical detector.

主权项

1. A sensor module for detecting and/or measuring physiological information from a subject, the sensor module, comprising:
a housing; at least one optical emitter supported by the housing; at least one optical detector supported by the housing; a first light guide supported by the housing, wherein the first light guide is in optical communication with the at least one optical emitter, and wherein the first light guide is configured to deliver light from the at least one optical emitter into a body of the subject; a second light guide supported by the housing, wherein the second light guide is in optical communication with the at least one optical detector, and wherein the second light guide is configured to collect light from the body of the subject; a motion sensor supported by the housing, wherein the motion sensor is configured to sense motion information from the subject; and a processor supported by the housing, wherein the processor is configured to remove motion artifacts from signals produced by the at least one optical detector in response to signals produced by the motion sensor, and wherein the processor is configured to process signals produced by the at least one optical detector to determine subject heart rate and at least one of subject respiration rate, subject blood flow, subject heart rate variability, subject blood gas level, subject blood pulse volume, subject blood analyte levels, subject breathing rate, subject breathing volume, subject blood oxygen levels, subject blood pressure, subject VO2max, the 1st derivative of at least one subject blood pulse, and the 2nd derivative of at least one subject blood pulse.
