1. A wearable infusion pump assembly comprising:
a reservoir for receiving an infusible fluid; and
a fluid delivery system configured to deliver an infusible fluid and having a fluid path from the reservoir to an external infusion set, wherein the fluid delivery system comprising:
a controller;
a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the external infusion set, the pump assembly having a plunger;
an optical pump sensor assembly for sensing the position of the plunger and sending pump sensor output to the controller;
a first valve assembly in the fluid path and configured to selectively isolate the pump assembly from the reservoir;
a volume measurement assembly for measuring the amount of fluid delivered by the fluid delivery system,
a second valve assembly in the fluid path and configured to selectively isolate the volume measurement assembly from the pump assembly,
a third valve assembly in the fluid path and configured to selectively isolate the volume measurement assembly from the external infusion set; and
a first optical valve sensor for sensing the position of one of said first or second valve assemblies and sending a first valve sensor output to the controller, whereby the controller controls the pump assembly, and said first and second valve assemblies using the sensor outputs to deliver a preset measure of fluid to the external infusion set.
