Moreover, the invention relates to a method for measuring the pressure in the fluid system of such a supply device.

Abstract: The present invention relates to an apparatus for dialysis treatment which has device(s) for balancing fresh and used dialysis fluid. The present invention also relates to a method of balancing fresh and used dialysis fluid. The apparatus and method according to the present invention for balancing fresh and used dialysis fluid are characterized in that the individual balancing chambers of the balancing system receive both fresh dialysis fluid and used dialysis fluid, the functions of the balancing chambers being alternately interchanged. In this way, exact balancing can be achieved even when the volumes of the individual chambers differ from one another. Over the period of the treatment as a whole, the differences between the volumes balance each other out due to the cyclic interchange of the chambers.

Abstract: A necking machine (1) having a plurality of processing stations on a rotating tool carrier (7). The motion of the tool carrier (7) with respect to the work pieces is carried out by a crankshaft (25). This is carried out by a non-constant gear. The gear includes two non-round gearwheels (21, 23) that improve a rotational-speed profile of the crankshaft (25) and thus a velocity profile, in particular, in an area of the dead center.

Abstract: 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.

Abstract: The present invention relates to a disposable bag which comprises a multilayer film for accommodating a fluid, and a device which comprises a support holder for the disposable bag according to the invention in which the disposable bag is arranged. The present invention also relates to a process for the production of the disposable bag.

Abstract: 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.

Abstract: The present invention relates to a clot trap that comprises a disc-shaped screen surface for collecting clots in a fluid flowing through the screen surface. It further relates to an external blood cassette and a blood circuit, as well as a treatment apparatus.

Abstract: The present invention relates to an air separator for an extracorporeal blood circuit for separating out air from a fluid flowing through the air separator, comprising an air separation chamber having at least one inflow passage and at least one outflow passage.

Abstract: A blood treatment device, in particular a dialysis machine, which permits both single-needle and dual-needle operation. The device has a blood treatment unit, in particular a dialyzer that has an inlet connected to a feed line and an outlet connected to a return line. The feed line has two parallel line branches with a positive displacement pump being connected into the first and second line branches. To produce a fluid connection between the outlet of the dialyzer and one of the two pumps, a connection line is provided. For dual-needle operation, the feed and return lines are connected to an arterial and a venous needle. For single-needle operation, the feed and return lines are brought together and connected to a common needle. The connection line permits single-needle operation without great changes to the structure of the blood treatment device.
