Abstract

A removable power supply cover assembly ( 116 ) for an infusion pump is disclosed. The assembly includes a housing body configured to removably attach to an infusion pump, a conductor assembly ( 1020 ) attached to the housing body, a power supply contact assembly, and a spring ( 1002 ) attached to the power supply contact assembly and the conductor assembly. An electrical coupling between a power supply to the conductor assembly is formed through the spring.

First claim

What is claimed is:

1. A removable power supply cover assembly configured to be removably attached to an infusion pump, the cover assembly comprising:
a removable cover body configured to removably attach to the infusion pump, wherein the removable cover body is a cover for a power supply cavity in an infusion pump, wherein the removable cover body seals the power supply power supply cavity and maintains a power supply within the power supply cavity;
a conductor assembly attached to the cover body;
a spring having a first and second end, the first end attached to the conductor assembly; and
a power supply contact assembly attached to the second end of the spring and extending further from the removable cover body than the conductor, wherein an electrical coupling between a power supply to the conductor assembly is formed through the spring.

2. The removable power supply cover assembly of claim 1 further comprising a battery.

3. The removable power supply cover assembly of claim 1 wherein the housing body further comprising:
a sealing assembly for releasable engaging at least a portion of an enclosure assembly and forming an essentially water-tight seal between the removable cover assembly and the enclosure assembly.

4. The removable power supply cover assembly of claim 3 wherein the sealing assembly comprising an o-ring assembly.

5. The removable power supply cover assembly of claim 1 wherein the housing body is configured to allow access to a power supply cavity and effectuate removable insertion of a removable power supply assembly into the power supply cavity.

6. An infusion pump assembly comprising:
an enclosure assembly;
a pump assembly positioned at least partially within the enclosure assembly and configured to effectuate the dispensing of the infusible fluid contained in a reservoir assembly;
a power supply cavity positioned within the enclosure assembly; and
a removable cover assembly configured to releasably engage the enclosure assembly, the removable cover assembly comprising:
a removable cover body configured to removably attach to the enclosure assembly, wherein the removable cover body is a cover for the power supply cavity in the infusion pump assembly, wherein the removable cover body seals the power supply power supply cavity and maintains a removable power supply assembly within the power supply cavity;
a conductor assembly attached to the cover body;
a spring having a first and second end, the first end attached to the conductor assembly; and
a power supply contact assembly attached to the second end of the spring and extending further from the removable cover body than the conductor, wherein an electrical coupling between a removable power supply to the conductor assembly is formed through the spring.

7. The infusion pump assembly of claim 6 further comprising wherein the reservoir assembly positioned at least partially within the enclosure assembly and configured to contain an infusible fluid.

8. The infusion pump assembly of claim 6 further comprising processing logic positioned at least partially within the enclosure assembly and configured to control the pump assembly.

9. The infusion pump assembly of claim 6 further comprising a battery.

10. The infusion pump assembly of claim 6 wherein the removable cover assembly comprising:
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.

11. The infusion pump assembly of claim 10 wherein the sealing assembly comprising an o-ring assembly.

12. The infusion pump assembly of claim 6 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.
