Abstract: An easy to use, low-cost dispenser container delivers individual test strips ready for insertion into a glucometer without requiring extraction of individual strips manually from the package. The system may provide a dry, contaminant-free, storage device whereby stored strips are not repeatedly exposed to humidity. As each strip is removed from the device, a gasket seals the storage, Desiccants may be used to maintain the integrity of the storage environment. A convenient built-in waste receptacle for used strips may include a mechanical means for removing the used strips from the glucometer without the need for touching the bloodied end of the used strips.

Abstract: 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.

Abstract: The concentration of glucose in the anterior chamber of an eye is non-invasively measured by guiding a beam through a polarizer (4), a quarter wave plate (6), a polarization modulator (20), and an analyzer (7). After initializing the polarizer and the analyzer to extinguish the beam, it is guided parallel to the iris (56) of the eye (50) and introduced into the anterior chamber (57), wherein it is refracted, impinges on and is reflected from the iris, and exits the anterior chamber approximately collinear with the portion (55A) of the beam incident on the anterior chamber. The beam then is guided onto a detector (10), and a sufficient signal is applied to the polarization modulator to extinguish the beam. The signal represents the glucose concentration in the patient's blood.

Abstract: A polarimeter adapted for measurement of the concentration of glucose in a sample includes a laser beam passing through a first polarizer and an optical modulator and split into a measurement beam passing through a FIRST ANALYZER to a first detector coupled to a first amplifier and a reference beam passing through a SECOND ANALYZER to a second detector coupled to a second amplifier. Identical multiple filtering and summing operations are performed on outputs of the first and second amplifiers to produce a first &PSgr;2/2 signal and a first 2&bgr;&PSgr; signal in response to the measurement beam and a second &PSgr;2/2 signal and a second 2&bgr;&PSgr; signal in response to the reference beam. The measurement beam is stabilized by comparing the second &PSgr;2/2 signal to a first reference signal to produce a first error signal and comparing the second 2&bgr;&PSgr; signal to a second reference signal to produce a second error signal.
