Abstract:
1. A system for determining the concentration of an analyte in at least one body fluid in body tissue, the system comprising: an infrared light source; a body tissue interface to deliver light from the infrared light source to the body tissue; a load cell for measuring an amount of pressure applied to the body tissue; a detector adapted to receive spectral information corresponding to the infrared light reflected from the at least one body fluid and to convert the received spectral information into a signal indicative of the spectral information; and a central processing unit adapted to use the signal indicative of the spectral information and the measured pressure from the load cell in an algorithm built upon correlation with the analyte in body fluid, the algorithm adapted to convert the received spectral information into the concentration of the analyte in at least one body fluid.
