Prototype of a Peristaltic Pump for Applications in Biological Phantoms

In this work we present the design, construction and characterization of a peristaltic pump for biological applications. The design considers the blood flow with the possibility in a future, to perform the simulation of cardiac pathologies. The system is based on a peristaltic pump (which emulates how the heart works), Teflon hoses and a blood mimic [2] with rheological properties similar to real blood. The phantom is able to simulate blood flow, as well as the ability to show variations in blood flow, according to the selected mode. The blood flow was validated with commercial Doppler equipment. This is the first version of the prototype and it can be modified and arranged for a correct functioning of the phantom, after the experimental evaluations.
