    • An electroosmotic (EO) pump is provided that includes a housing having a pump cavity, a porous core medium and electrodes. The porous core medium is positioned within the pump cavity to form an exterior reservoir that extends at least partially about an exterior surface of the porous core medium. The porous core medium has an open inner chamber provided therein. The inner chamber represents an interior reservoir. The electrodes are positioned in the inner chamber and are positioned proximate the exterior surface. The electrodes induce flow of a fluid through the porous core medium between the interior and exterior reservoirs, wherein a gas is generated when the electrodes induce flow of the fluid. The housing has a fluid inlet to convey the fluid to one of the interior reservoir and the exterior reservoir. The housing has a fluid outlet to discharge the fluid from another of the interior reservoir and the exterior reservoir. The housing has a gas removal device to remove the gas from the pump cavity.
    • 提供一种电渗(EO)泵,其包括具有泵腔的壳体,多孔芯介质和电极。 多孔芯介质定位在泵腔内以形成至少部分地围绕多孔芯介质的外表面延伸的外部储存器。 多孔芯介质具有设置在其中的开放内室。 内室表示内部储存器。 电极定位在内室中并且位于外表面附近。 电极通过多孔芯介质在内部和外部储存器之间引导流体流动,其中当电极引起流体流动时产生气体。 壳体具有用于将流体输送到内部储存器和外部储存器中的一个的流体入口。 壳体具有流体出口,以从另一个内部储存器和外部储存器排出流体。 壳体具有用于从泵腔去除气体的气体去除装置。
