1. A pump system comprising:
a processing unit; and
an interface module fixedly coupled to the processing unit and defining a recess configured to receive a pump cartridge, the recess defining a plurality of arcuate perimeter edges corresponding to the pump cartridge, wherein the plurality of arcuate perimeter edges includes an arcuate side edge and the recess further defining a first straight longitudinal edge intersecting with the arcuate side edge, a second straight longitudinal edge intersecting with the arcuate side edge and disposed on an opposite side of the arcuate side edge from the first straight longitudinal edge, and a third straight longitudinal edge disposed across from the first straight longitudinal edge defining a first recess width, the third straight longitudinal edge also disposed and across from the second straight longitudinal edge defining a second recess width, wherein the first recess width is greater than the second recess width, the recess comprising:
a plurality of cartridge engagement slots configured for removably coupling the pump cartridge; and
a cartridge-facing surface comprising a positioning feature slot extending orthogonal to a general plane of the cartridge-facing surface.
