CONTROLLING DRUG DELIVERY TRANSITIONS

摘要

Devices, systems, and techniques for transitioning between different drug delivery sources or different drug concentrations may account for diffusion and mixing of drug within the fluid. In one example, a method may include determining a flow rate for a fluid to be delivered to a patient via a drug pump and a catheter in fluid communication with a reservoir of the drug pump. The fluid includes a drug. The method also includes determining a concentration profile of the drug delivered via the catheter, wherein the concentration profile identifies a volume of delivered fluid needed to achieve a target transition dose of the drug. The method further includes determining, by a processor and based on the flow rate and the concentration profile, an initial delivery period required to achieve the target transition dose by delivering the fluid at the flow rate.

1. A method comprising:
determining a flow rate for a fluid to be delivered to a patient via a drug pump and a catheter in fluid communication with a reservoir of the drug pump, wherein the fluid comprises a therapeutic agent; determining a concentration profile of the therapeutic agent delivered via the catheter, wherein the concentration profile identifies a volume of fluid deliverable by the drug pump and needed to achieve a target transition dose of the therapeutic agent; and determining, by a processor and based on the flow rate and the concentration profile, an initial delivery period required to achieve the target transition dose by delivering the fluid at the flow rate.
