Patent number: 11872554Abstract: A microfluidic device includes an inlet port configured to receive a sample, a first reaction chamber fluidically coupled to the inlet port, a first pump fluidically coupled to the inlet port, a second pump fluidically coupled to a mixing chamber, a metering channel fluidically coupled to the first reaction chamber and to the mixing chamber, and one or more second reaction chambers fluidically coupled to the mixing chamber. The first pump is configured to move fluid from the inlet port to the first reaction chamber and from the first pump to the inlet port. The second pump is configured to move fluid from the second pump to the mixing chamber, from the first reaction chamber to the mixing chamber, and from the mixing chamber to the one or more second reaction chambers.Type: GrantFiled: March 9, 2020Date of Patent: January 16, 2024Assignee: ABBOTT DIAGNOSTICS SCARBOROUGH, INC.Inventors: Alexander Schenk zu Schweinsberg, Austin Matthew Derfus, Justin Davidson, Karthikeyan Kumaravadivelu, Maulik Vinod Patel, Olaf Piepenburg, Catherine Jean Greenwood, Oliver Nentwich

Publication number: 20190064158Abstract: A combination of capillary forces and gas pressure is used to control the movement of liquid samples within a microfluidic device. A liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action partway along the capillary channel. As the liquid sample moves, a pressure of a gas acting upon a distal gas-liquid interface of the liquid sample increases by an amount sufficient to stop further movement of the liquid sample. To initiate further movement of the liquid sample, a pump connected to a distal portion of the capillary channel decreases the pressure of the gas acting upon the distal gas-liquid interface of the liquid sample by an amount sufficient to permit the liquid sample to move by capillary action further along the capillary channel of the microfluidic device.Type: ApplicationFiled: October 24, 2018Publication date: February 28, 2019Inventors: William Patrick COFFEY, Paul Michael CRIVELLI, Austin Matthew DERFUS, Tuan Hoang DO, Remus Anders Brix HAUPT, Emily PARKER, Gregory RENEFF, Armando Raul TOVAR
