Abstract
The present application is directed to systems and methods associated with infusion pumps, which can optionally utilize an electrokinetic driving mechanism. Infusion pumps, including electrokinetically-driven pumps, are discussed, along with schemes for controlling their operation. As well, systems and methods of detecting malfunctions in infusion pumps are discussed. Any number of malfunctions can be detected including the presence of occlusions and/or leaks. In some instances, a measurement associated with some aspect of electrokinetic phenomena (e.g., an electrode measurement such as voltage or current) is compared with one or more sample values, the comparison allowing an indication of pump malfunction to be determined. A variety of such measurements and comparison techniques are discussed in the present disclosure.
