abstract

  • The most widely used blood pump, the standard roller pump, is considered a constant flow device. It has the advantages of simplicity and availability, but lacks self regulation features. There are advantages to having the roller pump self-regulate its flow downward as the filling pressure decreases below a predetermined level. This paper describes the concept of a new pump chamber for the standard roller pump that controls blood flow as a function of the filling pressure. The flow characteristic of the pump is demonstrated with data collected from in vitro tests.
