Fluid handling cassette having a spectroscopic sample cell
First Claim
1. A fluid handling module configured for removable engagement with a reusable main fluid handling instrument, said module comprising:
- a module housing;
a first fluid passageway extending from said module housing, said first fluid passageway having a patient end remote from said housing, said first fluid passageway configured to provide fluid communication with a bodily fluid in a patient;
a fluid component separator in fluid communication with said first fluid passageway, said fluid component separator configured to separate at least one component from a portion of said bodily fluid drawn from said patient; and
a spectroscopic sample cell configured to hold at least a portion of said first component.

Abstract
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.

22. A method for extracting and analyzing a bodily fluid of a patient, said method comprising:
-
attaching a fluid handling module to a reusable fluid handling instrument, wherein;
said fluid handling module comprises a fluid component separator, a spectroscopic sample cell and a first fluid passageway; and
said reusable fluid handling instrument comprises an analyte detection system;
drawing a volume of a bodily fluid from said patient into said first fluid passageway;
with said fluid component separator, separating a first component from said volume of bodily fluid drawn from said patient;
holding at least a portion of said first component of said bodily fluid in said spectroscopic sample cell; and
with said analyte detection system, analyzing said first component to determine a concentration of an analyte. - View Dependent Claims (23, 24, 25, 26, 27)
