The cassette comprises a housing configured for releasable attachment to the pumping apparatus in an aligned position. A space defined within the housing is configured to receive a rotor of the pumping apparatus therein when the housing is in the aligned position. The space is free of fluid carrying conduits disposed for engaging the rotor. An identification member is positioned in the housing. The identification member is operable to induce an expected identification reader response when the identification reader is functioning properly. The cassette is arranged to operatively align the identification member with the identification reader when the housing is in the aligned position.

Abstract: A peristaltic pump is able to deliver accurate volumes over the life of a pump set that is operated on by the pump to drive the flow of fluid. The pump delivers fluid in small volumes or aliquots. In order to deliver fluid at any particular selected flow rate, the pump determines how often the rotor will rotate. The pump is able to calculate aliquot volume based on selected flow rate, but also on a factor that compensates for changes in the dimensions of the pump set over its life.

Abstract: A controller for operating a pumping apparatus to supply fluid to a patient through a pump set includes a processor programmed to instruct a first source of electromagnetic radiation to emit electromagnetic radiation in a direction for striking a safety interlock of the pump set. The processor activates a first electromagnetic radiation detector to detect the electromagnetic radiation emitted from the first source. The processor instructs a second source of electromagnetic radiation to emit electromagnetic radiation in a direction for striking the safety interlock. The processor activates a second electromagnetic radiation detector to detect the electromagnetic radiation emitted from the second source. The processor controls the pumping apparatus to operate for pumping fluid in the pump set only when electromagnetic radiation emitted from the first source is detected by the first detector and when the electromagnetic radiation emitted from the second source is not detect by the second detector.
