Active disposable microfluidic system with externally actuated micropump

摘要

The present invention is a microfabricated system for performing biochemical analysis on a test sample of substance. The system includes a substrate with a sample entry port, one or more pump chambers, and one or more mixers. Channels are connected between the pump chambers and the mixers to conduct the flow of the substance during the processing. A magnetic member is positioned on a diaphragm over each pump chamber, creating a pump that is actuated by attracting and repelling the magnetic member with a magnet. Each magnetic member is attracted or repelled independently of the other magnetic members.
