1. An apparatus, comprising:
a base, comprising:
two motors; and
a mechanical coupling mechanism; and
a cartridge, shaped to define two stators and respective pairs of ports in fluidic communication with the stators,
the cartridge being removably insertable into the base and comprising two rotors disposed, respectively, within the stators, and
the mechanical coupling mechanism being configured to mechanically couple the rotors to the motors, respectively, such that, following insertion of the cartridge into the base, the motors rotate the rotors, thereby pumping fluid through the pairs of ports,
wherein the rotors comprise respective first connectors, each of which has a non-circular shape, and
wherein the mechanical coupling mechanism comprises:
two non-circular shafts coupled with the motors, respectively, such that the shafts are rotatable by the motors;
two second connectors, each of which has the non-circular shape, slidably disposed over the shafts, respectively, such that the second connectors are rotatable with the shafts; and
two springs slidably disposed over the shafts, respectively, the springs being configured to couple the shafts with the rotors by pushing the second connectors toward the first connectors such that, upon the second connectors rotating into alignment with the first connectors, the second connectors mate with the first connectors.
