Abstract
Disclosed herein are devices and methods for detecting blood glucose levels in a subject that involve passively quantifying mid-infrared emissions from the eye of the subject.
Claims26
An apparatus for detecting blood glucose levels in a subject, comprising:
- a thermographic device configured to capture mid-infrared (MIR) electromagnetic emissions;
- and
- a computing device communicatively connected to the thermographic device, wherein the computing device comprises a processor and memory operably connected to the processor, wherein the memory has computer-executable instructions stored thereon that, when executed by the processor, cause the processor to:
- receive mid-infrared (MIR) electromagnetic emissions captured from the thermographic device;
- using the emissions captured from the thermographic device, calculate a radiance value;
- correct the radiance value based on a temperature of a subject's eye at the time of capture;
- and
- correlate the corrected radiance value to a blood glucose value of the subject.

A method for detecting blood glucose levels, comprising:
- capturing, using a thermographic device, mid-infrared (MIR) electromagnetic emissions in a subject's eye;
- transmitting the captured emissions from the subject's eye to a computing device;
- calculating, using the computing device, a radiance value based on the emissions captured from the thermographic device;
- correcting, using the computing device, the radiance value based on a temperature of the subject's eye at the time of capture;
- and
- correlating, using the computing device, the corrected radiance value to a blood glucose value of the subject.
3 more elements
A blood-glucose detection apparatus comprising:
- a mid-infrared (MIR) electromagnetic emissions sensor having a field of view,
- a frame configured to align the sensor in front of a subject's eye,
- a processor and computerized memory configured to measure blood glucose concentration in the subject by initiating computer implemented instructions to:
- store a set of standard control values comprising average control radiance values, for a selected wavenumber, wherein the control values are accessible by the processor,
- receive from the sensor, in a measurement cycle utilizing the selected wavenumber, a radiance measurement corresponding to MIR electromagnetic emissions;
- calculate an average radiance measurement from the respective radiance measurements corresponding to respective measurement cycles in a plurality of measurement cycles;
- correlate the average radiance measurement to the known glucose concentration having a control radiance value equal to the average radiance measurement.
