Patent number: 9701995Abstract: A test cartridge for use in sample analysis is provided. The test cartridge includes a reservoir card that further includes a reagent that includes living biological cells; and a test cartridge base configured to accept the reservoir card. The reservoir card is configured to interface with a test cartridge base through at least one fluid port. The test cartridge base includes an elliptical reaction chamber having a central axis and an inlet channel connected to the reaction chamber. The inlet channel is positioned above the reaction chamber at an angle of 15-60 degrees above the horizontal and is offset from the central axis of the reaction chamber. Upon introducing a sample to be analyzed into the test cartridge base through the inlet channel, the sample is homogeneously mixed with the reagent while minimizing damage to the living biological cells.Type: GrantFiled: March 26, 2015Date of Patent: July 11, 2017Assignee: Fundamental Solutions CorporationInventors: Marvin R. Williams, Charles McBrairty, Daniel W. Pfautz, Thomas J. Zupancic, Lingchun Zeng, Andrew Weiman, Richard S. Brody, Joseph D. Kittle, Anthony Truscott, Robert Baranowski

Patent number: 9023640Abstract: A portable system for real time detection of the presence of an infectious agent in a biological sample employs a reagent which detects the presence of a specific infectious agent in the sample, and emits a detectable signal when the reagent reacts with the sample and detects the presence of the infectious agent. A test cartridge has a reaction chamber for receiving the sample and the reagent. The reaction chamber has a predetermined internal geometry and at least one inner surface. Introducing the sample and the reagent into the test cartridge mixes the sample and the reagent. A testing unit receives the test cartridge, and includes a sensor for detecting an emitted detectable signal. The detection of the emitted detectable signal is indicative of the presence of the infectious agent in the sample.Type: GrantFiled: December 11, 2012Date of Patent: May 5, 2015Assignee: Fundamental Solutions CorporationInventors: Marvin R.
