Abstract
A simple simulator has been constructed, evaluated and used for performance studies of prosthetic aortic valves, balloon assist devices and Koroktof sounds and ausculatory cuff blood pressure measurements. A direct drive piston pump is used. Elastic soft rubber tubes with distributed resistances allow modeling of normal and diseased pressure pulse waves. Pressure pulse amplitude amplification is modeled with tube segments of decreasing diameters. Satisfactory proximal pressure pulse shapes are obtained with a soft rubber tube of uniform diameter.
