The present invention relates to a method of removing blood from an extracorporeal blood circuit following termination of a blood treatment session, wherein blood is concurrently removed both from an arterial conduit portion and from a venous conduit portion of the extracorporeal blood circuit. It further relates to a method for recognizing and/or eliminating air inclusions in or from an extracorporeal blood circuit and a treatment apparatus as well as a tube system.

Method of removing blood from an extracorporeal blood circuit, treatment apparatus, and tube system

An external functional means comprises at least one housing body, at least one chamber integrated into the housing body for receiving medical fluids, at least one passage integrated into the housing body for receiving and/or conducting a medical fluid, and at least one valve means completely or partly integrated into the housing body for controlling or regulating a fluid flowing through the external functional means. The invention further specifies a blood treatment apparatus and methods which may be carried out by means of the external functional means of the invention and by means of the blood treatment apparatus, respectively.

External functional means, blood treatment apparatus for receiving an external functional means in accordance with the invention, and method

The present invention relates to a reception means for receiving fluids, which comprises a fluid surge redirection element comprising at least one flow-conditioning body that is adapted and intended to divide the fluid surge of the inflowing fluid into at least two partial fluid surges. It further relates to an external functional means as well as a treatment apparatus comprising a reception means in accordance with the invention.

Reception means for receiving medical fluids, as well as external functional means and medical treatment apparatus

A method for removing blood from an extracorporeal blood circuit of a treatment apparatus for the extracorporeal blood treatment of a patient following termination of a blood treatment session, wherein the treatment apparatus includes at least one extracorporeal blood circuithaving a conduit interior; at least one blood pump for conveying blood inside the conduit interior of the extracorporeal blood circuit; and at least one substitute pumpfor introducing or conveying at least one substituate fluid inside the conduit interior of the extracorporeal blood circuit. The method comprises feeding of air into the conduit interior of the extracorporeal blood circuit by operating the blood pump, and introducing substituate fluid into the conduit interior of the extracorporeal blood circuitby operating the substitute pump. In addition, a suitable apparatus is described.

Method for removing blood from an extracorporeal blood circuit for a treatment apparatus following termination of a blood treatment session, and apparatus for performing said method

An apparatus for treating a medical liquid is provided which includes a treatment machine having a coupling surface, with a cassette made of a hard part having liquid-conducting passages which are covered by a flexible film being able to be coupled to the coupling surface of the treatment machine. A corresponding medical cassette is also provided. An air-free coupling of the flexible film of the cassette to the treatment machine is ensured in that air can be sucked out areally along a plane between the flexible film and the coupling surface during the coupling process and/or with a coupled cassette. A method for coupling the cassette and a method for checking the leaktightness of the cassette via the vacuum control of the air suction is also provided.

Device and method for treating a medical fluid and medical cassette

A method for emptying a blood tubing set of a blood treatment device that includes an extracorporeal blood circuit with a membrane filter includes supplying air or gas to the blood tubing set to displace liquid therein. The blood tubing set includes arterial and venous patient blood tubes in communication with a first chamber of the membrane filter. The device also includes a substituate line which opens into the arterial blood tube and/or into the venous blood tube, and a substituate pump. To empty the blood tubing set, the arterial blood tube and the venous blood tube are connected to one another to provide a circuit that includes the membrane filter, the arterial blood tube, and the venous blood tube. The substituate line is disconnected, and the air or gas is pumped into the blood tubing set so as to displace liquid into a second chamber of the membrane filter.
