20090045342 | METHOD AND APPARATUS FOR DETERMINING AN ANALYTE CONCENTRATION IN A SAMPLE HAVING INTERFERENTS - A method and apparatus are described that permit an analyte concentration to be estimated from a measurement in the presence of compounds that interfere with the measurement. The method reduces the error in the analyte concentration in the presence of interferents. The method includes the use of a set of measurements obtained for a large population having a range of known analyte and interfering compound concentrations. From a sample measurement, which may or may not be one of the population, likely present interferents are identified, and a calibration vector is calculated. | 02-19-2009 |
20090326343 | FLUID HANDLING CASSETTE HAVING A SPECTROSCOPIC SAMPLE CELL - A fluid handling module is configured for removable engagement with a reusable main fluid handling instrument. The module includes a module housing and a first fluid passageway extending from the module housing. The first fluid passageway has a patient end remote from the housing. The first fluid passageway is configured to provide fluid communication with a bodily fluid in a patient. A fluid component separator is in fluid communication with the first fluid passageway. The fluid component separator is configured to separate at least one component from a portion of the bodily fluid drawn from the patient. A spectroscopic sample cell is configured to hold at least a portion of the first component. | 12-31-2009 |

20110011167 | FLUID HANDLING CASSETTE WITH A FLUID CONTROL INTERFACE AND SAMPLE SEPARATOR - A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface. | 01-20-2011 |
20110190606 | FLUID HANDLING CASSETTE - A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface. | 08-04-2011 |
20120232362 | BODILY FLUID COMPOSITION ANALYZER WITH DISPOSABLE CASSETTE - Disclosed is an apparatus for analyzing the composition of bodily fluid. The apparatus can include a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and a pump unit in operative engagement with the fluid handling network. The pump unit can have an infusion mode, in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode, in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus can include a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample. | 09-13-2012 |
