A PNEUMATIC DRIVING DEVICE FOR MICRO FLUIDS WHEREIN FLUID PUMPING IS GOVERNED BY THE CONTROL OF THE FLOW AND DIRECTION OF INCIDENT PLURAL GAS STREAMS

摘要

A pneumatic driving device and the associated method for micro fluids, wherein the pneumatic driving device for micro fluids is constructed by connecting a fluid pipe with a structure that is formed by two gas stream inlets, a gas stream fender, a gas stream flow path and a gas stream outlet. The suction, exclusion and stagnation for the micro fluids inside the fluid pipes can be accomplished by adjusting the flow rates of the gas streams into the device at the two gas stream inlets. In the invention several pneumatic driving devices are connected to form a single recursive pneumatic driving device by the concept of recursion, and the micro fluids inside several fluid pipes can be controlled to mix or to separate through the recursive pneumatic driving device by adjusting the flow rates of the gas streams into the device at different gas stream inlets.
