The goal of this design is to create a more time efficient pump that wastes a smaller amount of gadolinium and infuses with controllable precision. A prototype has been constructed that uses Bernoulli’s principle of ideal fluid flow. This prototype will be able to deliver a bolus injection, immediately followed by the infusion, while also having the ability to change the flow rates of gadolinium and saline throughout the infusion. This will save both time during the procedure, and money expended on gadolinium. The design is still in the beginning stages, and there are a few modifications and additions to be made to have a device that can be used accurately in an MRI environment.
