Overall System Architecture
The objective of this project is to design and build a Hemodynamic Simulator. Hemodynamic
Simulator is a modular system that will allow reproduction of the flows and pressures associated
with human circulatory system. The simulator will be constructed alongside components that
will allow the generation and measurement of arbitrary dynamic flow rates, volumes and
pressures. In addition, impact of variations of the characteristics of system components such as
vessel size, compliance, fluid constitution and topology will also be generated and measured.
The system also be capable of measuring fundamental hydrodynamic properties by a variety of
invasive and non-invasive techniques, i.e. in-line flow meters, Doppler ultrasound.
The simulator will be regulated via standard bidirectional communication link designed into an
electronic control module. The module will allow the simulator be controlled, modified and
monitored via a computer application. The control module will be a stand-alone user interface
providing system operational parameters such as flow rates, pressure ranges and preprogrammed profiles, such as for a toddler, infant, people of age 65 yr +, etc.
