INFUSION PUMP ASSEMBLY
First Claim
1. A wearable infusion pump assembly comprising:
- a reservoir for receiving an infusible fluid; and
a fluid delivery system configured to deliver the infusible fluid from the reservoir to an external infusion set, wherein the fluid delivery system includes;
a volume sensor assembly configured to receive a quantity of the infusible fluid from the reservoir, the volume sensor assembly including;
an acoustically contiguous region having a volume that varies based upon the quantity of infusible fluid received from the reservoir, andan acoustic energy emitter configured to provide acoustic energy at a plurality of frequencies to excite a gas included within the acoustically contiguous region.
