Arthropump with peristaltic effect and pulsatile flow

This paper describes a pump of novel design, with peristaltic effect and pulsatile flow. Special features are the facility for occlusive or non-occlusive pumping, and the absence of moving parts in the flow section. A compressible drive medium allows 'individual' transport of big particles in the pumped fluid. Pumping of a relatively high proportion of solids in liquid is possible. This pump is suitable for handling living structures in cell and tissue separating systems. Pumping of fluids with increased viscosity and abrasives in liquid is also feasible
