Abstract: Illustrative embodiments of diaphragm pumps having an automatic priming function, as well as related systems and methods, are disclosed. In one illustrative embodiment, a method of priming a diaphragm pump includes sensing, with a pressure sensor disposed at a fluid outlet of the diaphragm pump, a pressure of a fluid being pumped by the diaphragm pump, transmitting a pressure signal associated with the sensed pressure from the pressure sensor to a controller of the diaphragm pump, and identifying, on the controller, whether the diaphragm pump is primed by determining whether a characteristic of the pressure signal has reached a threshold.

Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump utilizes an air efficiency device in order to optimize the amount of a compressed air in a pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings is achieved by minimizing the amount of required compressed air.

Abstract: A portable pumping system provides insulin or other drugs to a user. A shape memory element is used to actuate the pump and an intelligent system controls the actuator in order to minimize stresses within the system and provide accurate and reliable dosage delivery. The control system utilizes various types of feedback to monitor and optimize the position of the pumping mechanisms. Physical design aspects also minimize stress and the combination of the physical design aspects and the intelligent operation of the system results in a lightweight and cost effective pump that may be used in a disposable fashion if desired.
