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.

主权项

1. A headset, comprising:
a speaker, an optical emitter, an optical detector, and a temperature sensor; an earbud housing configured to be supported by an ear of a subject, wherein the earbud housing encloses the speaker, optical emitter, optical detector, and temperature sensor, wherein the housing comprises at least one window configured to engage a non-ear canal region of the ear when the housing is supported by the ear; and light transmissive material associated with the at least one window and that is at least partly external to the at least one window, wherein the light transmissive material is in optical communication with the optical emitter and detector via the at least one window, wherein the light transmissive material is configured to deliver light from the optical emitter to the non-ear canal region of the ear of the subject and to collect light external to the housing and deliver the collected light to the optical detector; wherein the temperature sensor is configured to measure a temperature of the tympanic membrane.
