Bei der Entwicklung von Herzunterstützungssystemen oder Systemen für den totalen Herzersatz muss untersucht werden, ob ein definierter Blutfluss gewährleistet werden kann und entsprechende Druckdifferenzen erzeugt werden können. Zudem ist eine möglichst geringe Blutschädigung von großer Bedeutung. Zur Untersuchung der Förderleistung wird der erzeugte Volumenstrom bei verschiedenen Leistungsaufnahmen (Stromstärken) ermittelt. Es zeigt sich ein linearer Zusammenhang zwischen Leistungsaufnahme (A) und erzeugtem Fluss (l/min), da der erzeugte Druckgradient der Kraft des Kolbens proportional ist. Im Weiteren werden Druck- und Flussbeziehungen bei maximaler Leistungsaufnahme gemessen und dargestellt. Hier zeigt sich, dass bis zu einer Nachlast ...
