Abstract
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.
Claims20
A micro-fluidic device for performing a diagnostic or analytical test, the device comprising:
- a chamber;
- a microfluidic feature for performing an operation on the micro-fluidic device;
- and
- a bubble jet vacuum pump structured to control delivery of a fluid from the chamber to the microfluidic feature by pulling under vacuum, a selected volume of fluid into the microfluidic feature wherein another volume of fluid is ejected from a fluidic circuit including the bubble jet vacuum pump so as to create the vacuum.
