  • Patent number: 8298496
    Abstract: A fluidic configuration, both structural and methodological, for the injection of sample greatly reduces dead volume allowing rapid transition to 100% sample in a flow cell. For a continuous flow injection analysis system the structure and method provide counter flows to remove in one direction the dispersed region of the sample to waste before injecting non-dispersed sample into the flow cell by reversing the effective flow direction. The injection point itself is directly adjacent to the flow cell where all channels are microfluidic channels. Therefore, only the flow cell volume needs to be displaced during injection of sample in order to achieve 100% transition to sample within the flow cell. This greatly accelerates the rise and fall times thereby extending the kinetic range of the real-time interaction analysis instrument. In addition such rapid transition to sample improves overall data quality thereby improving kinetic model fitting.

  • Patent number: 8287739
    Abstract: An optical blood monitoring system with a ratiometric model determines hematocrit values for a hemodialysis patient, from which hemoglobin values for the patient are estimated. The ratiometric model is calibrated, normally against a cell counter, using blood from a blood bank. The blood from a blood bank is preserved in a long term preservative which is typically different than that found in clinical settings. The hematocrit value determined by the ratiometric model is scaled by scaling factor so that the estimated hemoglobin level output from the monitor consistently matches that measured in a clinical setting. The hematocrit scaling factor is substantially about 1.033 when the patient's blood sample is stored in a short term preservative ethylene diamine tetra acetic, and is substantially about 1.06 when the hematocrit is measured in the blood sample without preservative being added to the blood sample. The hemoglobin value can also be adjusted for altitude.
