Pump assembly with a removable cover assembly

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 infusible fluid;
• 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, the combination preventing the removable power supply assembly within the power supply cavity from being reverse-polarity electrically coupled to the processing logic, the power supply cavity having an access opening that is covered by the removable cover assembly when engaged with the enclosure assembly;
• and
• wherein the sealing assembly substantially surrounds the access opening.
