SAMPLE ELEMENT FOR REAGENTLESS WHOLE BLOOD GLUCOSE METER

摘要

A reagentless whole-blood analyte detection system includes an infrared radiation source, a detector, and a sample element (700, 800). The sample element (700, 800) includes an elongate member (705, 802), a first sample cell wall (716), a second sample cell wall (715), a cover (720), and a sample supply passage (750, 815). The first sample cell wall in part defines a first sample cell (740). The first and second sample cell walls comprise materials that transmits a substantial portion of radiation in a range of wavelengths between about 6 µm and about 12 µm. The cover (720) at least partially defines at least one of the first sample cell (740) and the second sample cell (745). The sample supply passage comprises a first branch (755) and a second branch (760). The first branch of the sample supply passage extends from the opening (735) to the first sample cell. The second branch of the sample supply passage extends from the first sample cell to the second sample cell.
