Abstract
Examples of fluid delivery drive system and/or pump system that creates a vacuum in a fluid line for drawing and expelling fluid are provided. The vacuum may be created by separating two components that are positioned within the sealed fluid line. Once the two components are separated and the fluid is contained within the volume created between the separated components, the two components may be shuttled within the sealed volume. The movement of the two components can seal off an inlet to the fluid line and then open a pathway to an outlet from the fluid line while ensuring the created volume between the two components is maintained constant. The two components can then be moved back together to expel the fluid from the created volume through the outlet for delivery, for example, to a patient. Other examples are disclosed and described.
