Methods and apparatus for extracting and analyzing a bodily fluid
First Claim
1. A fluid handling and analysis system, said system comprising:
- a fluid transport network comprising at least a first fluid passageway, said fluid transport network including a patient end configured to maintain fluid communication with a bodily fluid in a patient;
a sample analysis chamber and waste container, each accessible via said fluid transport network;
a pump unit in operative engagement with said fluid transport network, said pump unit having an infusion mode in which said pump unit is operable to deliver an infusion fluid to said patient through said patient end, and a sample draw mode in which said pump unit is operable to draw a volume of said bodily fluid from said patient through said patient end, toward said sample analysis chamber;
a spectroscopic fluid analyzer configured to analyze a sample of said bodily fluid while said sample is in said sample analysis chamber, and determine a concentration of at least one analyte;
said fluid transport network and said pump unit being configured to draw a volume of said bodily fluid from said patient, isolate a fraction of said bodily fluid from said volume, and pass said fraction to said sample analysis chamber and then to said waste container.

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.
