Abstract

An infusion pump assembly includes an enclosure assembly. A reservoir assembly is positioned at least partially within the enclosure assembly and is configured to contain an infusible fluid. A pump assembly is positioned at least partially within the enclosure assembly and is configured to effectuate the dispensing of the infusible fluid contained within the reservoir assembly. Processing logic is positioned at least partially within the enclosure assembly and is configured to control the pump assembly. A removable cover assembly is configured to releasably engage the enclosure assembly. A combination of the removable cover assembly and at least a portion of the enclosure assembly defines a power supply cavity configured to prevent a removable power supply assembly from being reverse-polarity electrically coupled to the processing logic.

Claims

1. An infusion pump assembly comprising:

an enclosure assembly;

a reservoir assembly positioned at least partially within the enclosure assembly and configured to contain an infusible fluid;

a pump assembly positioned at least partially within the enclosure assembly and configured to effectuate the dispensing of the infusible fluid contained within the reservoir assembly;

processing logic positioned at least partially within the enclosure assembly and configured to control the pump assembly; and

a removable cover assembly configured to releasably engage the enclosure assembly;

wherein a combination of the removable cover assembly and at least a portion of the enclosure assembly define a power supply cavity configured to prevent a removable power supply assembly from being reverse-polarity electrically coupled to the processing logic.

2. The infusion pump assembly of claim 1 wherein the removable cover assembly is configured to allow access to the power supply cavity and effectuate removable insertion of the removable power supply assembly into the power supply cavity.

3. The infusion pump assembly of claim 1 wherein the removable power supply assembly includes a battery.

4. The infusion pump assembly of claim 1 wherein the removable cover assembly includes:

a sealing assembly for releasable engaging at least a portion of the enclosure assembly and forming an essentially water-tight seal between the removable cover assembly and the enclosure assembly.

5. The infusion pump assembly of claim 4 wherein the sealing assembly includes an o-ring assembly.

6. The infusion pump assembly of claim 1 wherein the removable cover assembly includes:

a conductor assembly configured to electrically couple the removable cover assembly with an interior wall of the power supply cavity.

7. The infusion pump assembly of claim 1 wherein:

the removable cover assembly includes a first twist lock assembly; and

the enclosure assembly includes a second twist lock assembly configured to releasably engage the first twist lock assembly and effectuate the releasable engagement of the removable cover assembly and the enclosure assembly.

8. An infusion pump assembly comprising:

an enclosure assembly;

a reservoir assembly positioned at least partially within the enclosure assembly and configured to contain an infusible fluid;

a pump assembly positioned at least partially within the enclosure assembly and configured to effectuate the dispensing of the infusible fluid contained within the reservoir assembly;

processing logic positioned at least partially within the enclosure assembly and configured to control the pump assembly; and

a removable cover assembly configured to releasably engage the enclosure assembly, the removable cover assembly including a sealing assembly for releasably engaging at least a portion of the enclosure assembly and forming an essentially water-tight seal between the removable cover assembly and the enclosure assembly;

wherein a combination of the removable cover assembly and at least a portion of the enclosure assembly define a power supply cavity configured to allow removable insertion of a removable power supply assembly.

9. The infusion pump assembly of claim 8 wherein the removable cover assembly is configured to allow access to the power supply cavity and effectuate removable insertion of the removable power supply assembly into the power supply cavity.

10. The infusion pump assembly of claim 8 wherein the removable power supply assembly includes a battery.

11. The infusion pump assembly of claim 8 wherein the sealing assembly includes an o-ring assembly.

12. The infusion pump assembly of claim 8 wherein the removable cover assembly includes:

a conductor assembly configured to electrically couple the removable cover assembly with an interior wall of the power supply cavity.

13. The infusion pump assembly of claim 8 wherein:

the removable cover assembly includes a first twist lock assembly; and

the enclosure assembly includes a second twist lock assembly configured to releasably engage the first twist lock assembly and effectuate the releasable engagement of the removable cover assembly and the enclosure assembly.

20. The infusion pump assembly of claim 13 wherein the removable power supply assembly includes a battery.

14. An infusion pump assembly comprising:

an enclosure assembly;

a reservoir assembly positioned at least partially within the enclosure assembly and configured to contain an infusible fluid;

a pump assembly positioned at least partially within the enclosure assembly and configured to effectuate the dispensing of the infusible fluid contained within the reservoir assembly;

processing logic positioned at least partially within the enclosure assembly and configured to control the pump assembly; and

a removable cover assembly configured to releasably engage the enclosure assembly including a first twist lock assembly;

wherein a combination of the removable cover assembly and at least a portion of the enclosure assembly define a power supply cavity configured to allow removable insertion of a removable power supply assembly; and

wherein the enclosure assembly includes a second twist lock assembly configured to releasably engage the first twist lock assembly and effectuate the releasable engagement of the removable cover assembly and the enclosure assembly.

15. The infusion pump assembly of claim 14 wherein the removable cover assembly is configured to allow access to the power supply cavity and effectuate removable insertion of the removable power supply assembly into the power supply cavity.

16. The infusion pump assembly of claim 14 wherein the removable power supply assembly includes a battery.

17. The infusion pump assembly of claim 14 wherein the removable cover assembly includes:

a conductor assembly configured to electrically couple the removable cover assembly with an interior wall of the power supply cavity.

18. An infusion pump assembly comprising:

an enclosure assembly;

a reservoir assembly positioned at least partially within the enclosure assembly and configured to contain an infusible fluid;

a pump assembly positioned at least partially within the enclosure assembly and configured to effectuate the dispensing of the infusible fluid contained within the reservoir assembly;

processing logic positioned at least partially within the enclosure assembly and configured to control the pump assembly; and

a removable cover assembly configured to releasably engage the enclosure assembly, wherein a combination of the removable cover assembly and at least a portion of the enclosure assembly define a power supply cavity configured to allow removable insertion of the removable power supply assembly;

wherein the removable cover assembly includes a conductor assembly configured to electrically couple the removable cover assembly with an interior wall of the power supply cavity.

19. The infusion pump assembly of claim 18 wherein the removable cover assembly is configured to allow access to the power supply cavity and effectuate removable insertion of the removable power supply assembly into the power supply cavity.
