An Original Versatile Nonocclusive Pressure-Regulated Blood Roller Pump for Extracorporeal Perfusion

Currently, only a small number of centrifugal pumps are being used for
hemodynamic and/or respiratory support, but all of them have
limitations. This article aims to present the Rhône-Poulenc 06
nonocclusive pressure-regulated blood pump. This pump was developed in
France in the 1970s and used for decades in perfusion for cardiopulmonary bypass procedures, cardiac or lung assist as well as venovenous bypass
during liver transplant. The intrinsic properties of this pump allowed
us to describe a new technique for extracorporeal lung support in the
1980s, using a single cannula tidal flow venovenous bypass.
This pump compared favorably with conventional pumps in terms of flow
and pressure, hemolysis, pulsatility, safety, and cost-effectiveness. We
believe that this simple pump could be an alternative to more
sophisticated and expensive devices.
