    • Disclosed are embodiments of systems, apparatus, and methods for delivering a fluid. In one illustrative embodiment, a fluid delivery device includes a master piston coupled with at least one slave piston to move in unison with the master piston. A fluid power source, such as an electroosmotic plump, is also provided, which is configured to drive the master piston. The various pistons may be sized differently to provide for delivery rates that vary in proportion to the size difference between the pistons. In some embodiments, the fluid delivery device may provide both a driving force and a suction force such that a first fluid can be delivered out of a chamber while a second fluid is delivered into that chamber or a separate chamber.
    • 公开了用于输送流体的系统,装置和方法的实施例。 在一个示例性实施例中,流体输送装置包括与至少一个从动活塞相连接的主活塞以与主活塞一致地移动。 还提供流体动力源,例如电渗灌浆,其构造成驱动主活塞。 各种活塞的尺寸可以不同,以提供与活塞之间的尺寸差异成比例地变化的输送速率。 在一些实施例中,流体输送装置可以提供驱动力和吸力,使得第一流体可以被输送出室,而第二流体被输送到该室或单独的室中。
