Claims
- 1. A method for non-invasively determining the concentration of glucose in blood comprising the steps of:
removing glucose from a skin surface; achieving a non-induced static level of glucose at or within the skin surface as measured over a period of time, wherein the static level is correlateable to the level of glucose within the blood; and measuring the static level of glucose.
- 2. The method of claim 1 wherein the step of removing glucose comprises applying a glucose solvent to the skin surface.
- 3. The method of claim 3 further comprising the step of removing the glucose solvent.
- 4. The method of claim 4 wherein the step of removing the glucose solvent further comprises the step of applying a solvent to remove the glucose solvent.
- 5. The method of claim 1 wherein the step of achieving a non-induced static level of glucose at or within the skin surface takes less than 10 minutes.
- 6. The method of claim 5 wherein the step of achieving a non-induced static level of glucose at or within the skin surface takes less than 1 minute.
- 7. The method of claim 1 wherein the static level of glucose at or within the skin surface is correlateable to the level of glucose found in the blood to a degree that does not vary by more than 15%.
- 8. The method of claim 1 wherein the step of measuring comprises measuring with electrochemical sensors.
- 9. The method of claim 1 wherein the step of measuring comprises measuring with optochemical sensors.
- 10. The method of claim 1 wherein the step of measuring comprises measuring with near-infrared spectroscopy.
- 11. The method of claim 1 wherein the step of measuring comprises measuring with mid-infrared spectroscopy.
- 12. The method of either of claims 10 or 11 wherein the step of removing glucose does not interfere with IR spectra of glucose obtained during the step of measuring.
- 13. A method for calibrating a non-invasive device for determining the concentration of glucose in blood comprising the steps of:
removing glucose from a surface of skin; achieving a non-induced static level of glucose at or within the skin surface as measured over a period of time, measuring the static level of glucose; comparing the static level of glucose to a level obtained by a blood sample glucose determination; optionally adjusting the step of measuring the static level of glucose so that the static level is correlateable to the level of glucose obtained by the blood sample glucose determination.
- 14. The method of claim 13 wherein the step of achieving a non-induced static level of glucose at or within the skin surface takes less than 10 minutes.
- 15. The method of claim 14 wherein the step of achieving a non-induced static level of glucose at or within the skin surface takes less than 1 minute.
- 16. The method of claim 13 wherein the static level of glucose at or within the skin surface is correlateable to the level of glucose found in the blood to a degree that does not vary by more than 15%.
