    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： One embodiment of the present invention provides a piston assembly having a piston housing filled with an electrolyte; a housing within the piston housing that divides the piston housing into a first portion and a second portion, the housing having apertures, a shaft connecting the housing to a piston head outside of the piston housing; and a porous material inside of the housing in contact with the electrolyte. Additionally, there are provided a method for filling the delivery chamber with a delivery fluid by withdrawing the piston head from within the delivery chamber. Yet another embodiment provides a method for filling a fluid delivery assembly by withdrawing a shaft from within the fluid delivery assembly to simultaneously displace a moving pump element within the delivery chamber and bypass fluid around a housing in the pump chamber.

    摘要： The present invention provides a fluid delivery system having a first chamber, a second chamber and a third chamber; a flow-through pump element separating the first chamber from the second chamber; a moveable pump element separating the second chamber from the third chamber; a first outlet in communication with the third chamber; and second outlet in communication with the second chamber. Additionally, the present invention provides methods of operating a fluid delivery system having a first chamber, a second chamber and a delivery chamber by reducing the volume of the second chamber while increasing the volume of the delivery chamber without operation of a flow-through pump element that separates the second chamber from the first chamber.
