Patent ID: 7299079

Claim:
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 adapted to contact body tissue and to deliver light from the infrared light source to the contacted body tissue, the body tissue interface comprising a clamping device having two plates for contacting the body tissue; a detector adapted to receive spectral information corresponding to infrared light transmitted through the portion of body tissue being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information; a central processing unit adapted to compare the electrical signal to 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; and a load cell for measuring an amount of pressure applied to the body tissue by the clamping device.
