Wearable light-guiding bands for physiological monitoring
DC CAFCFirst Claim
1. A monitoring device, comprising:
- a band configured to at least partially encircle a portion of the body of a subject, the band comprising;
a generally cylindrical outer body portion and a generally cylindrical inner body portion secured together in concentric relationship, the inner body portion comprising light transmissive material, and having outer inner surface;
a layer of cladding material near the inner body portion inner surface; and
at least one window formed in the cladding material that serves as a light-guiding interface to the body of the subject; and
at least one optical emitter and at least one optical detector attached to the band;
wherein the light transmissive material is in optical communication with the at least one optical emitter and the at least one optical detector and is configured to deliver light from the at least one optical emitter to one or more locations of the body of the subject via the at least one window and to collect light from one or more locations of the body of the subject via the at least one window and deliver the collected light to the at least one optical detector.

Abstract
A monitoring device includes a band capable of encircling a portion of the body of a subject, and an optical emitter and detector attached to the band. The band includes comprises light transmissive material in optical communication with the optical emitter and optical 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 from one or more locations of the body of the subject and deliver the collected light to the optical detector. The monitoring device may include a signal processor configured to receive and process signals produced by the optical detector, a transmitter configured to transmit signals processed by the signal processor to a remote device, and/or an optical filter.
