Abstract
Systems for predicting a drug delivery profile as described herein include at least one drug pump and/or a controllable valve that produce a drug flow and dispense at least a first drug. The system also includes at least one carrier fluid pump and/or another controllable valve that produces a carrier fluid flow, a flow junction structure configured to receive the drug flow and the carrier fluid flow to produce a mixed flow, and a fluid path for carrying the mixed flow between the flow junction structure and a delivery point. The system further includes a processing device configured to predict the drug delivery profile at the delivery point based on determining a predicted time variation of drug concentration at the delivery point using at least a model of the mixed flow. The model includes a plurality of parameters related to propagation of the mixed flow through the fluid path.
