Abstract: One or more embodiments are directed to a microfluidic delivery system that dispenses a fluid in a direction that, at least in part, opposes gravity. In one embodiment, the microfluidic delivery system includes a microfluidic refill cartridge that is configured to be placed in a housing. The microfluidic refill cartridge includes at least one nozzle that faces upward or off to a side. The microfluidic refill cartridge includes a fluid transport member that allows fluid to travel upward from a fluid reservoir in opposition to gravity. A fluid path is located above the fluid transport member placing an end of the fluid transport member in fluid communication with a chamber and a nozzle. In response to the microfluidic delivery system receiving an electrical signal, an ejection element is configured to cause fluid in the chamber to be expelled through the nozzle. In response to the fluid being expelled from the nozzle, fluid may be pulled up through the fluid transport member and through the fluid path to refill the chamber.
Abstract translation: 一个或多个实施例涉及一种微流体输送系统，其在至少部分地与重力相反的方向上分配流体。 在一个实施例中，微流体递送系统包括配置成放置在壳体中的微流体补充盒。 微流体补充盒包括面向上或向外侧的至少一个喷嘴。 微流体补充盒包括允许流体相对于重力从流体储存器向上运动的流体输送构件。 流体路径位于流体输送构件上方，使得流体输送构件的端部与腔室和喷嘴流体连通。 响应于接收电信号的微流体传递系统，喷射元件构造成使得腔室中的流体通过喷嘴排出。 响应于从喷嘴排出的流体，流体可以被上拉通过流体输送构件并且通过流体路径以重新填充腔室。
