METHOD AND DEVICE FOR DETERMINING THE PRESSURE OR VOLUMETRIC FLOW OF MEDICAL FLUIDS

摘要

The invention relates to a method for determining a pressure of a medical fluid in a fluid line using at least one centrifugal pump (11), with the pressure being determined upstream of the centrifugal pump (11) taking into account information about a pressure downstream of the centrifugal pump (11), or with the pressure being determined downstream of the centrifugal pump (11) taking into account information about a pressure upstream of the centrifugal pump (11). To this end, in each case at least information about the volumetric flow in the fluid line and/or at least information about a rotational speed of the centrifugal pump (11) is taken into account. In addition, the invention relates to a method for determining a volumetric flow, to a processor, to a treatment device, to a digital storage medium, to a computer program product and to a computer program.
