1. A universal infusion pump assembly wherein a single type of infusion pump is used to emulate a large number of different pumps, said assembly comprising:

  • a. a single pump disposed in housing means for delivering a fluid to a patient;

    b. a set of replaceable memory modules, including a first and a second memory module, each memory module containing information including a program describing a non-patient specific user interface set, including operational parameters and a specific delivery profile characteristic of a respective dedicated pump;

    c. selection means mounted on said housing for generating patient-specific information for said patient; and

    d. microprocessor means associated with said housing for operating said single pump, said microprocessor means being coupled to one of said memory module, wherein when coupled to said first memory module, said microprocessor means reads said information from said first memory module and operates said single pump to emulate a first dedicated pump; and

    wherein said microprocessor means, when coupled to said second memory module, reads said information from said secondary memory module and reconfigures the single pump to emulate a second dedicated pump.
