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.
Claims12
A cuvette for use with an optical measurement system, the cuvette comprising:
- a first plate comprising a first window that is transparent to light emitted by the optical measurement system;
- a second plate comprising a second window that is transparent to the light emitted by the optical measurement system;
- a first spacer disposed between the first and the second plates;
- and
- a second spacer disposed between the first and the second plates, the first and the second spacers disposed to provide a sample supply passageway between the first and the second plates, the sample supply passageway having an opening disposed between the first and the second plates.
A fluid analysis system comprising:
- a fluid handling system that includes a sample extractor configured to draw a sample of bodily fluid from a patient;
- a fluid measurement system configured to measure the concentration of an analyte in the portion of the sample of bodily fluid;
- and
- a sample analysis chamber configured to hold the sample of bodily fluid, the sample analysis chamber comprising:
- a first window that is transparent to light emitted by the fluid measurement system;
- a second window that is transparent to light emitted by the fluid measurement system;
- and
- a first spacer and a second spacer positioned between the first window and the second piece to provide a gap between the first window and the second window, the first and the second spacers disposed to provide a sample supply passageway between the first and the second windows, the sample supply passageway having an opening disposed between the first and the second windows.
