Abstract

This involves a non-invasive glucose measurement device and a process for determining blood glucose level in the human body using the device. In typical operation, the glucose measurement device is self-normalizing in that it does not employ an independent reference sample in its operation. The device uses attenuated total reflection (ATR) infrared spectroscopy. Preferably, the device is used on a fingertip and compares two specific regions of a measured infrared spectrum to determine the blood glucose level of the user. Clearly, this device is especially suitable for monitoring glucose levels in the human body, and is especially beneficial to users having diabetes mellitus. The device and procedure may be used for other analyte materials which exhibit unique mid-IR signatures of the type described herein and that are found in appropriate regions of the outer skin.

Claims

1. A cleaning kit comprising:

a.) a glucose solvent, and

b.) a solvent for removing the glucose solvent, and

c.) a skin softener or skin pliability enhancer not having significant IR wavelength peaks between about 8.25 micrometers and about 8.75 micrometers or between about 9.50 micrometers and about 10.00 micrometers.

2. The cleaning kit of claim 1 wherein said solvent for removing the glucose solvent and skin softener or pliability enhancer are admixed.

3. The cleaning kit of claim 2 wherein each of said glucose solvent, and said admixed solvent for removing the glucose solvent and skin softener or pliability enhancer are present in sealed packets.

4. The cleaning kit of claim 2 wherein each of said glucose solvent and said admixed solvent for removing the glucose solvent and skin softener or pliability enhancer are present in an absorbent pad within sealed packets.

5. The cleaning kit of claim 1 wherein each of said glucose solvent, solvent for removing the glucose solvent, and skin softener or pliability enhancer are present in sealed packets.

6. The cleaning kit of claim 1 wherein each of said glucose solvent, solvent for removing the glucose solvent, and skin softener or pliability enhancer are present in an absorbent pad within sealed packets.

7. The cleaning kit of claim 1 wherein the glucose solvent comprises water or other highly polar solvent.

8. The cleaning kit of claim 7 wherein the glucose solvent further comprises an effective amount of a weak acid having no significant IR wavelength peaks between about 8.25 micrometers and about 8.75 micrometers or between about 9.50 micrometers and about 10.00 micrometers.

9. The cleaning kit of claim 8 wherein the weak acid comprises boric acid.

10. The cleaning kit of claim 1 wherein the solvent for removing the glucose solvent comprises isopropanol.

11. The cleaning kit of claim 1 wherein the skin softener or pliability enhancer comprises a mineral oil.
