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 split ring resonator antenna;
a controller configured to:
determine a first volume of infusible medical fluid delivered; and
based on the first volume of infusible medical fluid delivered, determine a time and volume for delivery of a second volume of infusible fluid.

2. The medical delivery device of claim 1 wherein the infusion device further comprising a disposable housing assembly and reusable housing assembly.

3. The medical delivery device of claim 2 wherein the reusable housing assembly further comprising a locking ring assembly, wherein the reusable housing assembly releasably engages the disposable housing assembly by way of the locking ring assembly.

4. The medical delivery device of claim 3 wherein the locking ring assembly comprising:
a spring;
a tab that connects to the spring; and
a magnet that connects to the tab.

5. The medical delivery device of claim 2 wherein the disposable housing assembly further comprising a reservoir wherein the pump effectuates the movement of infusible medical fluid from the reservoir to a volume sensor assembly.

6. The medical delivery device of claim 1 wherein the pump is driven by a shape memory alloy.

7. The medical delivery device of claim 1 further comprising a volume sensor assembly for determining the first volume and the second volume of infusible medical fluid delivered.

8. The medical delivery device of claim 7 wherein the volume sensor assembly comprising:
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.

9. A controller for a medical delivery device for delivering a medical fluid comprising:
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.

10. A medical delivery device comprising:
a disposable housing assembly and reusable housing assembly, the reusable housing assembly further comprising a locking ring assembly, wherein the reusable housing assembly releasably engages the disposable housing assembly by way of the locking ring assembly wherein the locking ring assembly comprising a spring, a tab that connects to the spring, and a magnet that connects to the tab;
a pump having a minimum and maximum delivery volume;
a controller configured to:
determine a first volume of infusible medical fluid delivered; and
based on the first volume of infusible medical fluid delivered, determine a time and volume for delivery of a second volume of infusible fluid.

11. The medical delivery device of claim 10 wherein the disposable housing assembly further comprising a reservoir wherein the pump effectuates the movement of infusible medical fluid from the reservoir to a volume sensor assembly.

12. The medical delivery device of claim 10 wherein the pump is driven by a shape memory alloy.

13. The medical delivery device of claim 10 wherein the infusion pump of claim further comprising a split ring resonator antenna.

14. The medical delivery device of claim 10 further comprising a volume sensor assembly for determining the first volume and the second volume of infusible medical fluid delivered.

15. The medical delivery device of claim 14 wherein the volume sensor assembly comprising:
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.

16. A medical delivery device comprising:
a pump having a minimum and maximum delivery volume;
a disposable housing assembly and reusable housing assembly wherein the disposable housing assembly further comprising a reservoir wherein the pump effectuates the movement of infusible medical fluid from the reservoir to a volume sensor assembly;

a controller configured to:
determine a first volume of infusible medical fluid delivered; and
based on the first volume of infusible medical fluid delivered, determine a time and volume for delivery of a second volume of infusible fluid.

17. The medical delivery device of claim 16 wherein the reusable housing assembly further comprising a locking ring assembly, wherein the reusable housing assembly releasably engages the disposable housing assembly by way of the locking ring assembly.

18. The medical delivery device of claim 17 wherein the locking ring assembly comprising:
a spring;
a tab that connects to the spring; and
a magnet that connects to the tab.

19. The medical delivery device of claim 16 wherein the pump is driven by a shape memory alloy.

20. The medical delivery device of claim 16 wherein the infusion pump of claim further comprising a split ring resonator antenna.

21. The medical delivery device of claim 16 further comprising a volume sensor assembly for determining the first volume and the second volume of infusible medical fluid delivered.

22. The medical delivery device of claim 21 wherein the volume sensor assembly comprising:
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.

23. 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; and
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 volume sensor assembly for determining the first volume and the second volume of infusible medical fluid delivered, the volume sensor assembly comprising:
an acoustically contiguous region having a volume that varies based upon the quantity of infusible fluid received from the reservoir, and
