发明名称 CHANNEL-LESS PUMP, METHODS, AND APPLICATIONS THEREOF
摘要 A channel-less microfluidic pump includes a cartridge including a substrate and an actuatable film layer disposed on the substrate, and a manifold having at least three actuatable void volumes separated by a plurality of wall sections and an actuatable flexible layer disposed on the manifold interfacing the actuatable film layer. In operation, the pump can be in an unactuated state wherein the actuatable film layer is disposed against the surface of the substrate or an actuated state wherein at least a portion of the flexible layer and a corresponding portion of the actuatable film layer are deflected into a corresponding void volume thus forming a fluidic volume between the deflected portion of the actuatable film layer and the surface of the substrate. In the actuated state, there is a fluidic gap between immediately adjacent void volumes formed by a thinned region of the flexible layer at a point of contact with a top surface of a wall section. A method of transporting fluid using the channel-less microfluidic pump is described.

主权项 1. A channel-less microfluidic pump comprising: a cartridge including a substrate having opposing external surfaces and an actuable film layer disposed on an external surface of the substrate; and a manifold comprising: at least three separate, actuable cavities forming at least in part, a top surface of the manifold, wherein each actuable cavity includes an actuation mechanism, further wherein in operation, the pump is characterized by one of an unactuated state wherein the actuable film layer is disposed immediately adjacent the surface of the substrate and an actuated state wherein at least a portion of the actuable film layer is deflected into a corresponding cavity thus forming a fluidic volume between the deflected portion of the actuable film layer and the surface of the substrate, further wherein, in the actuated state, the pump is further characterized by a fluidic gap between immediately adjacent fluidic volumes.
