1. A medical infusion pump system, comprising:
- a pump device including a drive system to dispense a medicine from the pump device, wherein the pump device comprises a pump housing structure that defines an opening into an internal space to receive a medicine cartridge and further comprises a detached cap member operable to engage with the pump housing structure and to pierce the medicine cartridge after the medicine cartridge is received in the internal space, wherein the drive system of the pump device comprises a segmented flexible piston rod that is incrementally advanced toward the medicine cartridge when the medicine cartridge is received by the pump housing structure;
a first removable controller device having a first user interface, the first user interface comprising a first display to provide information regarding the dispensation of a first medicine, the first removable controller device being removably attachable to the pump device and being electrically connected to the pump device when removably attached;
a first prefilled medicine cartridge to slidably insert through the opening of the pump housing and into the internal space defined by the pump housing, the first prefilled medicine cartridge containing only the first medicine;
a second removable controller device having a second user interface that is different from the first user interface, the second user interface comprising a second display to provide information regarding the dispensation of a second medicine that is different from the first medicine, the second removable controller device being removably attachable to the pump device and being electrically connected to the pump device when removably attached; and
a second prefilled medicine cartridge to slidably insert through the opening of the pump housing and into the internal space defined by the pump housing, the second prefilled medicine cartridge containing only the second medicine that is different from the first medicine.
