A blood circulation system for an extracorporeal blood treatment machine includes: an arterial circulation section; a venous circulation section; a dynamic bubble trap; and an air separator. The blood circulation system conducts blood, during the operation of a blood pump of the extracorporeal blood treatment machine, from a patient to a dialysis unit and from the dialysis unit to the patient. The blood circulation system also includes a recirculation or branch line connected to the bubble trap in order to return part of the blood that flows into the bubble trap into the blood circulation system, upstream of the bubble trap. An extracorporeal blood treatment machine includes the blood circulation system.

Air elimination device for extracorporeal blood treatment

An extracorporeal blood treatment machine includes a blood treatment device, a conveying device for conveying blood through the blood treatment device, and a connection mask designed to interchangeably receive a tube set in a predefined arrangement. The tube set has pressure-monitoring lines that branch off from the tube set and can be connected to pressure sensor connections located on the connection mask. The pressure sensor connections are spaced apart and positioned so as to match the tube set such that, when the tube set is mounted in the predefined arrangement on the connection mask, each pressure-monitoring line, owing to its limited length and the predefined arrangement of the associated branch on the blood treatment machine, can be connected exclusively to only one of the pressure sensor connections. A corresponding tube set is used with the extracorporeal blood treatment machine.

A blood treatment device for extracorporeal blood treatment and a method for monitoring the fill level of blood with the blood treatment device. The device includes at least one blood conducting system and at least one chamber container for separating bubbles from the blood to be treated. The device further includes a blood pumping device designed to pump the blood and generate pressure pulses with a predefined frequency in the blood conducting system. The blood treatment device additionally has at least one pressure detection sensor for capturing the pressure pulse introduced by the blood pumping device and a data processing unit designed to derive a fill level parameter from the pressure pulse captured and to modify the state of an information signal as a function of the fill level parameter. At least one alarm device is activated as a function of the state of the information signal.

A method and apparatus for priming an extracorporeal blood system. The extracorporeal blood system includes an arterial blood line, a venous blood line, a pump segment for interaction with a peristaltic blood pump of the apparatus and a blood treatment unit. A port of the venous blood line is connected to a venous blood port of the blood treatment unit. A port of the arterial blood line is connected to an arterial blood port of the blood treatment unit. The extracorporeal blood system is connected to a reservoir containing priming liquid. The non-occluded extracorporeal blood system is subsequently filled with priming liquid and, after filling with priming liquid, the pump segment is automatically occluded by a blood pump.
