The present invention concerns a pump provided with a control module and an attachable fluid reservoir cassette. The control module includes a pumping mechanism for pumping fluid from the fluid reservoir to the patient. The cassette is provided with appropriate indicia to identify differences between a plurality of cassettes. The control module further includes cassette indicia identification structure for identifying indicia on the cassette. One type of cassette identification system includes a projection extending from the cassette and structure associated with the control module which engages the projection. Another type of cassette identification system includes a light reflecting system which utilizes light from the control module and reflected off the cassette. Still other types of cassette identification systems utilize other non-contact switches or sensors to sense indicia on the cassette to identify the cassette from a plurality of cassettes.

[ What is claimed is:] [1.] A pump apparatus comprising:a pump including a processor and a pumping mechanism for pumping fluid through a fluid tube;a removable cassette mounted to the pump, the cassette including a fluid tube positioned adjacent to the pumping mechanism of the pump, the cassette including a light reflector;a light emitter associated with a tube interface region of the pump, for directing light toward the light reflector, the light reflector positioned to reflect light back toward the tube interface region of the pump;a light receiver associated with the tube interface region of the pump for receiving light reflected from the light reflector and for sending a signal to the processor indicative of the light being sensed.
