Abstract
Fluid pumps and medical treatment devices, in particular dialysis machines, include devices configured such that operating pressures and flow rates of the fluid pumps assume desired characteristics, in particular constant values or controlled profiles. The operating point of a peristaltic hose roller pump is adjusted based on an angle of rotation of a pump rotor, or by adjusting the operating point of a centrifugal pump in accordance with a profile.
