Abstract

Methods and apparatus for translating a continuous-delivery delivery profile into a plurality of periodic bolus deliveries.

Claims

1. A method comprising the steps of:

receiving one or more infusion parameters that define a continuous-delivery delivery profile with an ambulatory infusion device programming unit; and

translating the continuous-delivery delivery profile into a plurality of periodic boluses with the ambulatory infusion device programming unit.

2. A method as claimed in claim 1, further comprising the step of:

transferring instructions corresponding to the plurality of periodic boluses to an ambulatory infusion device.

3. A method as claimed in claim 1, wherein

the continuous-delivery profile includes at least two different delivery rates.

4. A method as claimed in claim 1, wherein

the continuous-delivery profile includes a plurality of delivery rates, at least two of which are different, that are associated with respective portions of a 24-hour cycle.

5. A method as claimed in claim 1,

wherein the periodic boluses are separated by time intervals, and

the method further comprises the step of receiving the periodic bolus time interval with ambulatory infusion device programming unit.

6. A method as claimed in claim 5, wherein

the volume of each periodic bolus is substantially equal to the volume of fluid that would have been delivered during the preceding time interval in accordance with the continuous-delivery delivery profile.

7. A method as claimed in claim 5, wherein

the continuous-delivery delivery profile includes at least one delivery rate defined in terms of fluid transfer device actuations;

each periodic bolus is defined in terms of fluid transfer device actuations; and

the number of fluid transfer device actuations of each periodic bolus is substantially equal to the number of fluid transfer device actuations that would have occurred during the preceding time interval in accordance with the continuous-delivery delivery profile.

8. A method as claimed in claim 5, wherein

the time interval is at least 5 minutes.

9. A method as claimed in claim 1, further comprising the step of:

displaying a graphical representation of the continuous-delivery delivery profile and a graphical representation of the plurality of periodic boluses with the ambulatory infusion device programming unit.

10. A method as claimed in claim 9, wherein

the graphical representation of the periodic boluses comprises a plurality of spaced bolus markers superimposed over the graphical representation of the continuous-delivery delivery profile.

11. A method as claimed in claim 10, wherein

the spacing between the bolus markers is indicative of a bolus interval.

12. A method as claimed in claim 9, wherein

the color of the graphical representation of a continuous-delivery delivery profile comprises the graphical representation of a plurality of periodic boluses.

13. A method as claimed in claim 12, wherein

the color of the graphical representation of a continuous-delivery delivery profile is indicative of a bolus interval.

14. A method as claimed in claim 9, further comprising the steps of:

receiving a bolus interval;

wherein the graphical representation of a plurality of periodic boluses is a function of the received bolus interval.

15. A method as claimed in claim 1, further comprising the step of:

displaying a graphical representation of the plurality of periodic boluses with the ambulatory infusion device programming unit.

16. A method as claimed in claim 15, wherein

the graphical representation comprises a plurality of spaced bolus markers.

17. A method as claimed in claim 16, wherein

the spacing between the bolus markers is indicative of a bolus interval.

18. A method as claimed in claim 15, further comprising the steps of:

receiving a bolus interval;

wherein the graphical representation of a plurality of periodic boluses is a function of the received bolus interval.

19. A programming unit for use with an ambulatory infusion device, the programming unit comprising:

means for storing a continuous-delivery delivery profile; and

means for translating the continuous-delivery delivery profile into a periodic bolus profile including a plurality of periodic boluses separated by time intervals; and

means for transmitting the periodic bolus profile to the ambulatory infusion device.

20. A programming unit as claimed in claim 19, further comprising:

means for receiving one or more infusion parameters that define a continuous-delivery delivery profile.

21. A programming unit as claimed in claim 19, further comprising:

means for displaying a graphical representation of the continuous-delivery delivery profile and a graphical representation of the periodic bolus profile.
