Wearable Monitoring Devices Having Sensors and Light Guides
First Claim
1. A monitoring device, comprising:
- at least one optical emitter comprising an emitting surface;
at least one optical detector comprising a detecting surface;
at least one housing supporting the at least one optical emitter and the at least one optical detector, wherein the at least one housing comprises at least one window, and wherein the at least one housing is configured to be attached to a body of a subject; and
light transmissive material associated with the at least one window, wherein the light transmissive material is in optical communication with the at least one optical emitter via the at least one window and is configured to deliver light from the at least one optical emitter to the body of the subject via a portion thereof, and wherein the light transmissive material portion and the at least one optical emitter emitting surface face substantially a same direction.

Abstract
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.
