Abstract:
1. A cartridge for analyzing a biologic fluid sample, comprising: a base plate having a body with a chamber surface, a body passage, and a chamber entry passage, wherein the body passage is in fluid communication with the chamber entry passage, and the chamber entry passage extends through to the chamber surface; a sample inlet port having an inlet passage in fluid communication with the body passage; a first chamber wall having a height extending outwardly from the chamber surface; a second chamber wall having a height extending outwardly from the chamber surface, spaced apart from the first chamber wall; and a cover panel disposed in contact with the first and second chamber walls, wherein the cover panel, first and second chamber walls, and the chamber surface define an analysis chamber; wherein the cover panel is optically transparent, and the cover panel includes a material which enables the cover panel to be sufficiently flexible to deflect and contact a central region of the chamber surface when subjected to capillary forces from the sample quiescently residing between the cover panel and the base plate chamber surface, and thereby separate the analysis chamber into a first sub-chamber disposed on a first side of the contact between the cover panel and the central region, and into a second sub-chamber independent from the first sub-chamber on a second side of the contact between the cover panel and the central region, opposite the first side.
