NEAR-INFRARED LASERS FOR NON-INVASIVE MONITORING OF GLUCOSE, KETONES, HBA1C, AND OTHER BLOOD CONSTITUENTS

摘要

A device for use with a smart phone or tablet, the device comprising: a measurement device including a light source comprising a plurality of light emitting diodes for measuring one or more physiological parameters, the measurement device configured to generate an input optical beam with one or more optical wavelengths, wherein at least a portion of the one or more optical wavelengths is a near-infrared wavelength between 500 nanometres and 2500 nanometres; the measurement device comprising one or more lenses configured to receive and to deliver a portion of the input optical beam to a sample, wherein the sample reflects at least a portion of the input optical beam delivered to the sample; the measurement device further comprising a receiver to receive at least a portion of the input optical beam reflected from the sample; the light source configured to increase a signal-to-noise ratio of the input optical beam reflected from the sample, wherein the increased signal-to-noise ratio results from an increase to the light intensity from at least one of the plurality of light emitting diodes and from modulation of at least one of the plurality of light emitting diodes; and the measurement device configured to generate an output signal; the device configured to communicate with the smart phone or tablet, the smart phone or tablet comprising a wireless receiver, a wireless transmitter, a display, a voice input module, a speaker, and a touch screen, the smart phone or tablet configured to receive and to process at least a portion of the output signal, wherein the smart phone or tablet is configured to store and display the processed output signal, wherein at least a portion of the processed output signal is configured to be transmitted over a wireless transmission link.
