Abstract
A medical pump device having a hose pump and a replaceable pump hose and provided with a reading means that reads a code mounted on the pump hose. The code corresponds to the deviation of the delivery volume of the individual hose from the set delivery volume. In dependence on the coding signals, the control signals for the pump drive are corrected so that defined delivery rates are obtained even with in wide hose tolerances.
