Patent ID: 7560686

Claim:
A medical pump for pumping fluid through a pump set loaded therein, said pump set being adapted for modifying electromagnetic radiation transmitted therethrough when properly loaded in the medical pump, said medical pump comprising: an emitter for emitting electromagnetic radiation having a predetermined wavelength; a detector for receiving electromagnetic radiation including the electromagnetic radiation having the predetermined wavelength emitted by the emitter and providing a detector signal representative of The received electromagnetic radiation; a filter for faltering the detector signal provided by the detector to exclude a portion of the detector signal representative of electromagnetic radiation having a wavelength other than the predetermined wavelength, said filter providing an output signal representative of the electromagnetic radiation having the predetermined wavelength received by the detector; a controller for determining whether a compatible pump set is properly loaded in the pump as a function of the output signal, said controller being configured to enable the pump for pumping when the compatible pump set is properly loaded in the pump as indicated by the output signal; and a second emitter for emitting electromagnetic radiation having a second predetermined wavelength; a second detector for receiving electromagnetic radiation including the electromagnetic radiation having the second predetermined wavelength emitted by the second emitter and providing a second detector signal representative of the intensity of the received electromagnetic radiation; and wherein the controller determines whether a compatible pump set is properly loaded in the pump as a function of the output signal and the second detector signal.
