  • Optical measurement of blood hematocrit incorporating a self-calibration algorithm
    Patent number: 6064474
    Abstract: An optical method for obtaining hematocrit values of blood uses the light transmittance properties of blood as a means of acquiring information about the blood sample. An algorithm is used to calculate the hematocrit value based on the absorbance spectra obtained at wavelengths of approximately 500 nm and 800 nm. These absorbance wavelengths are selected for their insensitivity to the oxygen saturation level of hemoglobin. Additionally, the algorithm has demonstrated insensitivity to plasma and other blood constituent scattering effects.

  • Optical carbon dioxide sensor, and associated methods of manufacture
    Patent number: 5714121
    Abstract: A method is provided for manufacturing a fiber optic sensor for detecting or measuring the concentration of carbon dioxide in a sample fluid. The method involves incorporation of a fluorescent indicator composition in a silicone capsule slidably arranged over the tip of a fiber optic, sealed with a suitable adhesive. To amplify the detectable signal obtained, the capsule is preferably fabricated so as to contain reflective particles, and tapers to a narrow tip. Novel optical sensors, manufactured using the aforementioned method, are provided as well.
