Perioperative patient blood glucose concentrations are determined by imposing patient effluent ultrafiltrate through a sample cell incorporated in an automated polarimeter. The device includes an optical platform, fluid handling subassembly, controlling electronics, and integration software. A stable collimated light source of known intensity and distinct specified wavelength is passed through an optical platform including a polarizer, retarder, bandpass filters, sample flow cell, analyzer and detector. The angular rotation of the transmitted light resulting from the glucose contained in patient ultrafiltrate collected in the sample flow cell is recorded and provides a measure of the glucose concentration. |
