A tube set for a blood handling apparatus, in particular an extracorporeal blood handling apparatus with an extracorporeal blood circuit or an apparatus for peritoneal dialysis, and a blood handling apparatus that has such a tube set are described. The tube set includes a device for collecting particles provided in a tube line portion of the tube set downstream of the tube portion placed in the occluding hose pump. The device for collecting particles prevents retention of solid substances that are possibly contained in the dialysis fluid, substituate or peritoneal solution. The tube set also has a device for limiting the pressure in the tube line portion between the occluding hose pump and the device for collecting particles. The device for limiting the positive pressure prevents an excessive positive pressure from building up in the tube line when fluid flow through the device for collecting particles is reduced or interrupted.

The present invention relates to an organizer for releasably accommodating components of blood tube sets for different extracorporeal blood treatment options, in particular for dialysis methods, by means of a blood treatment apparatus, as well as methods for manufacturing and preparing an organizer of the invention.

Organizer for releasably accommodating components of blood tube sets, and methods for manufacturing and preparing it

The present invention relates to a device and method for conveying fluids into the treatment unit of a medical treatment apparatus. The device and method according to the present invention are based on the fact that the fluid with which the treatment unit is supplied, circulates in a fluid circuit including the treatment unit. To balance fresh and used fluid fed to the treatment unit or conveyed from the treatment unit, a balancing unit with a balancing chamber is used, which can be incorporated into the fluid circuit including the treatment unit. It is thus possible to supply the fluid circuit continuously with fresh fluid or to carry away used fluid continuously from the fluid circuit. The supply and discharge of fresh and used fluid can take place at a different flow rate from the flow rate at which the fluid circulates in the fluid circuit via the treatment unit.

Method and device for conveying fluids into the treatment unit of a medical treatment apparatus, in particular into the dialyzer of a dialysis apparatus

The present invention relates to a system for the carrying out of a blood treatment, in particular a dialysis treatment, wherein the system has at least one blood treatment device, in particular a dialyzer, and at least one tank from which treatment fluid, in particular dialysis fluid, is removed during the carrying out of the blood treatment and/or into which consumed treatment fluid, in particular consumed dialysis fluid, is filled during the carrying out of the blood treatment, wherein the tank is an element of at least one mobile apparatus which can be connected to the blood treatment device such that at least one fluid connection can be established between the tank and the blood treatment device.

System for carrying out a blood treatment

The present invention relates to a device and a method for blood treatment in a single-needle operating mode. The blood treatment device has an extracorporeal blood circuit comprising a blood supply line leading to the inlet of a blood treatment unit and a blood return line leading away from the outlet of the blood treatment unit. Blood collecting means, for example a blood collecting container, is provided in the blood return line, said means being connected to means for storing gas, for example an air reservoir, by a flow line. The flow connection comprises two line branches, one branch being used to transfer gas from the air reservoir into the blood collecting container and the other branch being used to transfer gas from the blood collecting container into the air reservoir. The connection branch for transferring gas from the air store into the blood collecting container contains means for compressing air, for example a compressor. The device according to the present invention may be operated in such a way that the filling level of the means for collecting blood can be determined as precisely as possible.

The invention relates to a dialysis device () having a dialysate circuit comprising a first dialyzer () and a second dialyzer () wherein the first dialyzer () is connectable to a blood circulation of a patient via a blood feed line () and a recirculation (), an effluent for a retentate flow (Q) from the dialysate circuit to the second dialyzer () is provided and a permetate stream (Q) of the second dialyzer () in the dialysate circuit is passed to the first dialyzer (), the second dialyzer () comprising a filter membrane having a cut-off value of at least 500 Da and the first dialyzer () comprising a filter membrane having a cut-off value exceeding that of the second dialyzer ().

The present invention relates to a device for controlling a system for transporting blood, and a method for transporting blood in a blood line of an extracorporeal blood circuit of an extracorporeal blood treatment system. The present invention also relates to an extracorporeal blood treatment device comprising such a system for transporting blood. The method and device according to the present invention are based on the fact that a defined threshold value for the pressure in the blood line should not be exceeded. The system for transporting blood is controlled in such a way the blood in the blood line is transported in a pre-determined volume flow as long as the pressure in the blood line is below the pre-determined threshold value. When the pressure in the blood line reaches the pre-defined threshold value, however, the system for transporting blood is controlled such that a pressure value corresponding to the threshold value is set when the blood is transported in the blood line. As a result, when the threshold value for the pressure is reached, a regulation of the volume flow is replaced by a regulation of the pressure in the blood line.
