International Classification:

G01N033/48

US Classification:

356/039000

Abstract:

A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.

US Classification:

604066000, 600310000, 600316000, 600365000

Abstract:

In some embodiments, a system for bodily fluid sampling and analysis comprises a first fluid passageway having a patient end which is configured to provide fluid communication with a bodily fluid within a patient. A sample analysis chamber is accessible via the first fluid passageway. At least one pump is in operative engagement with the first fluid passageway such that the system is operable to periodically draw a sample of the bodily fluid from the patient through the first fluid passageway and toward the sample analysis chamber. A separator is accessible via the first fluid passageway and configured to remove at least one component from the sample of bodily fluid. A spectroscopic analyte detection system is configured to analyze the component of bodily fluid while the component of bodily fluid is in the sample analysis chamber, and determine a concentration of at least one analyte.
