Abstract
A citrate detector is provided for use in combination with a blood processing system and replacement fluid tubing or conduit of a disposable set. The citrate detector comprises a light source and a light detector. The light source is configured to emit a light having a wavelength absorbed by citrate, but at least partially transmitted by the replacement fluid conduit of the disposable set. The light detector is configured to receive at least a portion of the light from the light source and generate a signal indicative of the presence or absence of citrate in the replacement fluid conduit based, at least in part, on the amount of light received from the light source. A blood processing system incorporating such a citrate detector may include a flow detector for determining whether fluid is present in the conduit prior to checking for the presence of citrate.
