A company called AbioCor has developed an implantable replacement heart that is used as a substitute for diseased human hearts. ... The replacement heart is approximately the size of a grapefruit and works exactly like an actual human heart. Similar to a healthy human heart the replacement heart consists of two chambers that pump blood to their respective parts of the body. ... This replacement heart is capable of pumping approximately 10 liters of blood per minute.
The Implantable replacement heart is directly related to fluid mechanics for a couple of reasons. When the implantable replacement heart is working properly a balanced chamber called an artificial septum regulates pressure to each side of the heart. An internal pump is used to apply pressure to each side of the replacement heart. ... This blood flow that is created with the impeller and artificial septum mimics the pumping action of an actual human heart.
Inside the replacement heart is an active artificial septum which is the hearts main power plant. ...
When the implantable replacement heart is working correctly a few rules are true about its operation. ...
Since there must not be any accumulation of fluid mass in either ventricle for the replacement heart to work properly, the mass flow rate can be assumed constant using the conservation of mass theorem. ... This allows the following equation to be true for the implantable replacement heart when treating the ventricle as the controlled volume. ...
The velocity entering and exiting of the implantable replacement heart is related to the force used to push the artificial septum into the ventricle. ...
The fluid flow in this replacement heart is more complex than that of a pump with solid walls for one main reason, the artificial septum that creates the pressure or force on the blood is not a rigid body. ... Being able to understand the fluid mechanic principles of this replacement heart goes without saying, but also education on battery powered equipment and the transmitting of cordless power could be quite helpful.
