1. A body fluid analysis apparatus comprising:
- a single continuous sample chamber containing a plurality of compartments that hold body fluids for analysis;
at least one barrier separating the compartment plurality that filters the body fluid into components with dissimilar compositions in different compartments; and
the plurality of compartments comprising at least one optical compartment, the sample chamber formed of a material whereby the optical compartment passes greater than 50% of 8-10 micrometer light.

Abstract
A body fluid analysis apparatus comprises a unitary housing containing a single-celled chamber and having an entry portal for communicating body fluid between a patient body and the chamber. A barrier coupled at the entry portal prevents selected components of the body fluid from entering the chamber.

15. A method for analyzing body fluid comprising:
-
diverting a body fluid sample from a patient body through a single continuous sample chamber containing a plurality of compartments; filtering the diverted body fluid into components with dissimilar compositions in different compartments; optically measuring an analyte in the filtered body fluid in an optical compartment of the compartment plurality; and flushing the filtered body fluid back to the patient body after optical measurement. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
