Blood is a very special juice "- Mephisto already knew ...


The history of blood pumps began with the development of a roller pump for blood transfusions by ALLEN. It was further developed by Truax into the first double roller pump. After another modification by DeBAKEY his name is still connected to the roller pump today. In the first experimental perfusion systems, a variety of pumping systems such as diaphragm, hose, finger and roller pumps were used. Compared to the pulsatile pumping systems, nonpulsatile roller and centrifugal pumps were able to prevail in today's heart-lung machines.

 


A device from the Swiss company "Transfusex" ispresented, a simple rotary pump with clockwork for reading the transfused blood volume (Clinique Ste Elisabeth / Luxembourg).
