Bodily fluid composition analyzer with disposable cassette
First Claim
1. A method for extracting and analyzing a bodily fluid of a patient, the method comprising:
- removably attaching a disposable fluid handling module to a main analysis and control instrument, wherein;
the fluid handling module comprises;
at least one disposable fluid handling element further comprising a fluid passageway;
at least one control element interface;
a sample analysis chamber configured to intersect an analysis region of the main analysis and control instrument; and
a separator interface configured to engage a fluid component separator, wherein the fluid component separator is configured to separate the bodily fluid into multiple subcomponents;
engaging the at least one control element interface of the fluid handling module with at least one fluid control element of the main analysis and control instrument through an opening in the fluid handling module;
drawing a sample of the bodily fluid from the patient into the fluid handling module by actuating the at least one fluid control element;
separating the sample of the bodily fluid into multiple subcomponents by engaging the fluid component separator at the separator interface;
holding at least one subcomponent in the sample analysis chamber in a non-flowing state with the at least one fluid control element; and
analyzing the at least one subcomponent held in a non-flowing state with a body fluid analyzer to determine the concentration of an analyte.

Abstract
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.
