Abstract

An analyte detection system includes a first wearable module, a detector, and a processor. The first wearable module has an optical input through which electromagnetic radiation may enter said first wearable module. The first wearable module is configured to be worn on and engage a living wearer'"'"'s body such that electromagnetic radiation omitted by the body of the wearer can enter the first wearable module via the optical input. The detector is in optical communication with the optical input. The processor is in communication with the detector. The processor is configured to estimate the concentration of an analyte in the wearer'"'"'s tissue based on the emitted electromagnetic radiation.

Claims

1. An analyte detection system, comprising:

a first wearable module having an optical input through which electromagnetic radiation may enter said first wearable module and a detector in optical communication with said optical input, said first wearable module configured to be worn on and engage a living wearer'"'"'s body such that electromagnetic radiation emitted by said body can enter said first wearable module via said optical input; and

a processor in communication with said detector, said processor configured to estimate the concentration of an analyte in the wearer'"'"'s tissue based said emitted electromagnetic radiation.

2. The system of claim 1, wherein said processor is located in said first wearable module.

3. The system of claim 2, further comprising a power supply located in said first wearable module.

4. The system of claim 1, further comprising an optical path between said optical input and said detector.

5. The system of claim 4, wherein the optical path comprises an angular bend.

6. The system of claim 5, wherein the angular bend is approximately 90 degrees.

7. The system of claim 1, wherein said processor is located in a second module in communication with said first wearable module.

8. The system of claim 7, further comprising a power supply located in said second module.

9. The system of claim 1, wherein said processor is located in a second wearable module in communication with said first wearable module.

10. The system of claim 9, further comprising a power supply located in said second wearable module.

11. The system of claim 1, further comprising an alarm in communication with said processor and adapted to produce a signal when said concentration is outside of a predetermined range.

12. An analyte detection system, comprising:

a first wearable module having an optical input through which electromagnetic radiation may enter said first wearable module, said first wearable module being configured to be worn on and engage a living wearer'"'"'s body such that electromagnetic radiation omitted by said body can enter said first wearable module via said optical input;

a detector in optical communication with said optical input; and

a processor in communication with said detector, said processor configured to estimate the concentration of an analyte in the wearer'"'"'s tissue based on said emitted electromagnetic radiation.

13. The system of claim 12, wherein the detector is located in a second module.

14. The system of claim 12, further comprising a fiber optic cable adapted to provide optical communication between said optical input and said detector.

15. The system of claim 12, wherein the second module is wearable.

16. The system of claim 13, wherein the processor located in said second module.

17. The system of claim 16, wherein the second module is wearable.

18. The system of claim 13, further comprising a power supply located in said second module.

19. The system of claim 18, wherein the second module is wearable.
