Abstract
An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.
