Patent ID: 6847899

Claim:
An infusion pump system for delivering an intended intravenous fluid to a patient comprising: a pump housing with an exterior and an interior; means for inputting the identification of at least one component of interest in an intended intravenous fluid; a memory device for storing at least one parametric value uniquely associated with said at least one component of interest, a fluid path disposed within the interior of the housing for conducting the intravenous fluid to be delivered; a first emission source positioned adjacent to the fluid path for directing electromagnetic radiation into the fluid to enable the electromagnetic radiation to interact with at least one component of interest; a first detector positioned adjacent to the fluid path for detecting the electromagnetic radiation emerging from the fluid therein and for generating a signal for use in spectroscopically analyzing at least one component of the fluid in the fluid path, and means responsive to said signal for permitting said infusion only if said signal is substantially indicative of an intravenous fluid in the fluid path having said at least one component of interest.
