    摘要： 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.

    摘要： Systems and methods of detecting occlusions and fluid-loss conditions (e.g., disconnects and/or leakages) in an infusion pump are discussed. For example, electrokinetic infusion pumps may develop an occlusion in the fluid flow path, which can disrupt control of fluid dispersed from the pump. As well, an infusion set disconnect can also result in a fluid-loss that can be disruptive. Such disruptions can be troublesome to systems that control the infusion pump, such as closed loop controllers. Accordingly, systems and methods described herein can be used to detect such occlusions and fluid-loss conditions during infusion pump operation. For example, a position sensor can be used to monitor fluid flow from the infusion pump, with the measurement being compared with an expected value to detect an occlusion or fluid-loss condition. Other algorithms for utilizing the position sensor are also described.
