Contact lens with integrated pulse oximeter
First Claim
1. A contact lens, comprising:
- a substrate that forms at least part of a body of the contact lens; and
a pulse oximetry sensor located on or within the substrate configured to detect information associated with at least one of a blood oxygen content or a pulse rate of a wearer of the contact lens, the pulse oximetry sensor comprising;
one or more light emitting diodes configured to illuminate a blood vessel of at least one of a region of an eye or an eyelid; and
a detector configured to receive light transmitted through the blood vessel and generate the information, wherein the information includes a signal indicating an amount of light transmitted through the blood vessel;
wherein the one or more light emitting diodes and the detector are positioned away from a center of the contact lens;
the contact lens configured to maintain an orientation when worn on an eye such that the one or more light emitting diodes and the detector are not covered by an eyelid when the eye is open.

Abstract
Apparatus, systems and methods employing a contact lens having a pulse oximetry sensor to detect information indicative of a blood oxygen content and/or pulse rate of a wearer of the contact lens, are provided. In some aspects, a contact lens includes a substrate that forms at least part of a body of the contact lens and a pulse oximetry sensor located on or within the substrate that detects information associated with at least one of blood oxygen content or a pulse rate of a wearer of the contact lens. The pulse oximetry sensor comprises one or more light emitting diodes that illuminate a blood vessel of at least one of a region of an eye or an eyelid and a detector that receives light reflected from the blood vessel and generates the information.

10. A method comprising:
-
detecting, with one or more detectors of a pulse oximetry sensor, light transmitted through a blood vessel of a region of an eye or an eyelid, wherein the pulse oximetry sensor is located on or within a contact lens; and generating information associated with at least one of a blood oxygen content or a pulse rate of a wearer of the contact lens based, at least in part, on the detected light, wherein the pulse oximetry sensor further comprises one or more light emitting diodes, and wherein the one or more light emitting diodes and the one or more detectors are positioned away from the center of the contact lens, the contact lens configured to maintain an orientation when worn on an eye such that the one or more light emitting diodes and the one or more detectors are not covered by an eyelid when the contact lens is worn on the eye and the eye is open. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A device, comprising:
-
a memory that stores computer executable components; and a processor that executes the following computer executable components stored in the memory; an interface component that interfaces with and receives from a contact lens, data collected from a sensor on the contact lens relating to at least one of a blood oxygen content or a pulse rate of a wearer of a contact lens; a request component that transmits a request to the contact lens, wherein the request includes instructions for the sensor to generate calibration information when an eye on which the contact lens is worn is open and when the eye on which the contact lens is worn is closed, wherein the calibration information includes a baseline environmental light level; an analysis component that analyzes the received data and the calibration information and determines at least one of the blood oxygen content or the pulse rate of a wearer of a contact lens; and a display component that generates a display corresponding to the data. - View Dependent Claims (20)
