    • Various methods and devices are provided for delivering an infusion liquid using an electrokinetic infusion pump. The electrokinetic infusion pump can generally include an infusion housing having an infusion reservoir. The infusion reservoir has an infusion outlet and is capable of containing an infusion liquid. A plunger is movably coupled to the infusion housing and is adapted to be manually displaced relative to the infusion housing to load the infusion reservoir with infusion liquid. A movable partition can be disposed within the infusion housing and has a first surface in communication with an electrokinetic solution and a second surface, isolated from the first surface, in communication with the infusion reservoir. The electrokinetic infusion pump can further include an electrokinetic engine integrated within the plunger and adapted to selectively deliver electric potential across an electrokinetic porous media to cause the electrokinetic solution within the electrokinetic engine to displace the movable partition to effect delivery of at least a portion of the infusion liquid through the infusion outlet.
    • 提供用于使用电动输液泵输送输液的各种方法和装置。 电动输液泵通常可以包括具有输注储器的输注外壳。 输注槽具有输液口,并且能够容纳输液。 柱塞可移动地联接到输注壳体,并且适于相对于输注壳体手动移位以用输注液体加载输注储存器。 可移动隔板可以设置在输注外壳内,并且具有与电动溶液连通的第一表面和与第一表面隔离的与输注储存器连通的第二表面。 电动输液泵还可以包括集成在柱塞内的电动发动机,并且适于选择性地跨电动多孔介质输送电势,以使电动发动机内的电动溶液移动可动隔板,从而实现至少一部分 输液通过输液口。
