The present invention relates to an apparatus () for holding a disposable medical item, in particular a dialyzer (), plasma filter or adsorbent, for treating blood, a system () comprising such an apparatus, and a method for operating a disposable medical item for treating blood. A bearing device () is thereby configured to rotatably support the disposable item, and a drive device () is thereby configured to rotate the rotatably mounted disposable item around a longitudinal axis (L) extending substantially in a direction in which the blood flows through the disposable item when the disposable item is in operation. Alternatively or additionally, a sensor device () is configured to detect a rotation of the rotatably mounted disposable item around at least one rotational axis (L, Q), in particular around the longitudinal axis (L) and/or around a transverse axis (Q) running perpendicular to the longitudinal axis (L) and output corresponding sensor data. A control device () is further configured to control the drive device () and/or process the sensor data output by the sensor device ().

Apparatus for holding a disposable medical item for treating blood, system and method of operation

A method for determining a pressure of a medical fluid in a fluid line by using at least one centrifugal pump includes detecting the pressure upstream of the centrifugal pump while considering an information about a pressure downstream of the centrifugal pump, or detecting the pressure downstream of the centrifugal pump while considering an information about a pressure upstream of the centrifugal pump. Thereby, at least one information about the volume flow in the fluid line and/or at least one information about a rotation speed of the centrifugal pump are considered, respectively. The invention also relates to a method for determining a volume flow, an arithmetic unit, a treatment apparatus, a digital storage means, a computer program product and a computer program.

Method and device for determining the pressure or volumetric flow of medical fluids

A medical functional device includes at least one first fluid system for receiving at least one medical fluid, at least one first conveying device for conveying the medical fluid, at least one second fluid system for receiving at least one operating fluid, and at least one second conveying device for operating the at least first conveying device, in which the first conveying device is arranged such as to be actuated by means of the operating fluid. A treatment apparatus and a method are also described.
