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.

Claims

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.
