Micro-fluidic device

摘要

Embodiments described herein provide micro-fluidic systems and devices for use in performing various diagnostic and analytical tests. According to one embodiment, the micro-fluidic device includes a sample chamber for receiving a sample, and a reaction chamber for performing a chemical reaction. A bubble jet pump is structured on the device to control delivery of a fluid from the sample chamber to the reaction chamber. The pump is fluidically coupled to one or more chambers of the device using a fluidic channel such as a capillary. A valve may be coupled to one or more chambers to control flow into and out of those chambers. Also, a sensor may be positioned in one or more of the chambers, such as the reactant chamber, for sensing a property of the fluid within the chamber as well as the presence of a chemical within the chamber.

主权项

1. A micro-fluidic device for performing a diagnostic or analytical test, the device comprising:
a first chamber; a second chamber; and a bubble jet vacuum pump structured to control delivery of a fluid from the first chamber to the second chamber by pulling under vacuum, a selected volume of fluid into the second chamber wherein another volume of fluid is ejected from a fluidic circuit including the bubble jet vacuum pump so as to create the vacuum.
