Abstract

A fluid handling and analysis system comprises a fluid transport network comprising at least a first fluid passageway. The fluid transport network includes a patient end that is configured to maintain fluid communication with a bodily fluid in a patient. A sample analysis chamber and waste container are each accessible via the fluid transport network. A pump unit is in operative engagement with the fluid transport network. The pump unit has an infusion mode in which the pump unit is operable to deliver an infusion fluid to the patient through the patient end, and a sample draw mode in which the pump unit is operable to draw a volume of the bodily fluid from the patient through the patient end, towards the sample analysis chamber. A spectroscopic fluid analyzer is configured to analyze a sample of the bodily fluid while the sample is in the sample analysis chamber, and determine a concentration of at least one analyte. The fluid transport network and the pump unit are configured to draw a volume of the bodily fluid from the patient, isolate a fraction of the bodily fluid from the volume, and pass the fraction to the sample analysis chamber and then to the waste container.
