2C30.20 • Heart Pump Simulator

Photo Shows Demonstration Used at U.T. Austin

Instructions:

• The blue valve on the plastic tube should be horizontal (closed), open by turning it vertically.
• The water should drain into the first canister. If there are bubbles in the tubing, squeeze the blue bulb to clear them out.
• To demonstrate the pumping mechanism of the heart, squeeze the blue bulb.

Concepts Conveyed:

• This model demonstrates the valves in the heart that maintain the one-way blood flow.
• Arteries can adapt to and change with the varying hemodynamic conditions.
• Displays fluid dynamics and organic pumping mechanisms. Pressure within the tubes increases when the bulb is pumped, which causes the flow rate to increase as well, pushing the fluid through the tubes to expel into the graduated cylinder.

Demo Staff::

• Before transporting the demo, ensure all of the liquid is dispensed into the top chamber to avoid spillage.
• Be careful when picking up as most of the weight is on one side.
