    摘要: The invention relates to micropumps for infusing fluids. More specifically, the present disclosure describes and illustrates a micropump design that may be useful for infusing insulin into a diabetic patient. The disclosed design employs a pump chamber that has a diaphragm and a plurality of check valves that are configured to avoid leakage from the reservoir through the pump engine and into an infusion device and, also, to ensure the complete, accurate evacuation of the pump chamber.
