Abstract

A system for delivery of a volume of infusible fluid. The system includes a controller configured to calculate a trajectory for delivering infusible fluid, the trajectory comprising at least one volume of fluid, and determine a schedule for delivering the at least one volume of fluid according to the trajectory, wherein the schedule comprising an interval and a volume of infusible fluid for delivery. The system also includes a volume sensor assembly for determining the at least one volume of fluid delivered, wherein the controller recalculates the trajectory based on the volume of fluid delivered.

First claim

What is claimed is:

1. A medical delivery device comprising:
a pump having a minimum and maximum delivery volume;
a controller configured to:
determine a first volume of infusible medical fluid delivered;

based on the first volume of infusible medical fluid delivered, determine a time and volume for delivery of a second volume of infusible fluid; and

a reservoir wherein the pump effectuates the movement of infusible medical fluid from the reservoir to a volume sensor assembly wherein the volume sensor assembly comprises;
an acoustically contiguous region having a volume that varies based upon the quantity of infusible fluid received from the reservoir, and
an acoustic energy emitter configured to provide acoustic energy at a plurality of frequencies to excite a gas included within the acoustically contiguous region.

2. A medical delivery device comprising:
a reusable housing assembly;
a disposable housing assembly;
a pump having a minimum and maximum delivery volume;
a controller configured to:
determine a first volume of infusible medical fluid delivered;

based on the first volume of infusible medical fluid delivered, determine a time and volume for delivery of a second volume of infusible fluid; and

a reservoir wherein the pump effectuates the movement of infusible medical fluid from the reservoir to a volume sensor assembly wherein the volume sensor assembly comprises;
an acoustically contiguous region having a volume that varies based upon the quantity of infusible fluid received from the reservoir, and
an acoustic energy emitter configured to provide acoustic energy at a plurality of frequencies to excite a gas included within the acoustically contiguous region.

3. The medical delivery device of claim 2 wherein the acoustic energy emitter is in the reusable housing assembly.

4. The medical delivery device of claim 2 wherein the acoustically contiguous region is in the reusable housing assembly.

5. The medical delivery device of claim 3 wherein the acoustically contiguous region is in the reusable housing assembly.

6. A controller for a medical delivery device for delivering a medical fluid comprising:
an antenna for communicating with a remote device wherein the antenna is a split ring resonator;
a volume sensor assembly for determining a first volume of fluid delivered, the volume sensor assembly comprising an acoustically contiguous region having a volume that varies based upon the quantity of fluid received from the reservoir, and an acoustic energy emitter configured to provide acoustic energy at a plurality of frequencies to excite a gas included within the acoustically contiguous region;
a processor for determining the difference between a desired first volume of fluid to be delivered and the actual first volume of fluid delivered; and
a processor for determining a schedule and volume for delivering a second volume of fluid based on the difference.
