Fluid verification system and method for infusions
First Claim
1. An apparatus for verifying the composition of a fluid contained within a fluid infusion channel, wherein the channel includes a channel wall and an interior through which the fluid is conducted, the apparatus comprising:
- a source of light located and configured so as to direct light through the fluid contained within the channel;
a light sensor located so as to receive the light that was directed through the fluid contained within the channel after it has passed through the fluid, the light sensor providing light sensor signals representative of spectral data of the actual composition of the fluid contained within the channel; and
a processor that is adapted to compare the spectral data of the actual composition of the fluid with spectral data of an expected composition of the fluid contained within the channel.

Abstract
An apparatus and method are provided to verify the composition of a medical fluid in a fluid infusion channel by comparison with clinician-entered input. Light is transmitted through the channel and detected by a sensor that generates signals representative of the spectral data of the light detected. A processor compares the spectral data of the light detected to the spectral data associated with the expected contents of the channel to verify that the correct fluid is being infused.
