摘要： The present disclosure describes a blood oxygenator that includes a checkerboard layout of fluid (e.g., blood) and gas (e.g., oxygen) channels. When viewed as a cross-section through each of the channels of the oxygenator, the checkerboard configuration includes alternating gas and fluid channels in both the x-axis (e.g., in-plane) and in the y-axis (e.g., out-of-plane) directions. The oxygenator described herein reduces manufacturing complexity by using first, second, and third polymer layers that include asymmetrical channel designs. The channel designs include “open” gas channels, which are exposed to the ambient atmosphere. The oxygenator is placed within a pressure vessel to drive gas into each of the open gas channels, which in some implementations, negates the need for a gas manifold.

摘要： A compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.

摘要： A removable cartridge to be used in a system for extracting and detecting nucleic acids from heterogeneous samples includes a plurality of reservoirs defining at least a first wash buffer reservoir for holding a first wash buffer and a microfluidic assembly configured to attach to the plurality of reservoirs. The microfluidic assembly includes at least one sample reservoir and a nucleic acid extraction matrix in fluid communication to an automated sample preparation (ASP) reservoir through a first flow channel defined by the microfluidic assembly. An assay chamber is in fluid communication with a third flow channel and with the waste reservoir through a fourth flow channel such that a labeled nucleic acid-containing sample flows through the assay chamber and then to the waste reservoir, wherein vibration-driven mixing agitates fluids while present in the assay chamber. Finally, a nucleic acid-detecting microarray module is positioned in the assay chamber.
