The present invention relates to an apparatus for an extracorporeal blood treatment having an extracorporeal blood circuit in which a dialyzer is arranged and having a dialyzate circuit, wherein the blood circuit is in fluid communication with a first chamber and the dialyzate circuit is in fluid communication with a second chamber of the dialyzer, and wherein the two chambers are separated from one another by a semipermeable membrane, with a dialyzate pump for a conveying of the dialysis solution being present in the dialyzate circuit, wherein the apparatus has a control unit that is configured to operate the apparatus in a first phase and in a second phase following the first phase, wherein the dialyzate pump is operated with a smaller flow rate in the first phase than in the second phase and/or wherein the dialyzate pump conveys a dialysis solution in the first phase that is of a higher concentration with respect to at least one component than in the second phase.

Apparatus for an extracorporeal blood treatment

The present invention refers to a system and method for connecting a concentrate container with a blood treatment device with improved hygiene. Furthermore, the invention refers to a container and blood treatment device to be used in a method according to the present invention.

System and method for connecting a concentrate container with a blood treatment device

A dialysis machine is provided that includes an apparatus for treating fluids, in particular, for treating water for dialysis. The apparatus includes one or more hollow fiber membrane filters, a plurality of fluid lines, one or more sampling points, and one or more valve connections. The apparatus is configured such that contaminants can concentrate in a first hollow fiber membrane filter and conclusions can be drawn as to the contamination of the water. An analysis value can be determined from samples of concentrated contaminants. A method for monitoring the apparatus for contamination, is also provided.

The present invention refers to a container comprising a connection portion allowing for an easy, efficient and more hygienic connection of the container to a fluid dosing unit of a blood treatment device. According to the present invention the fluid dosing unit comprises a valve that fluidically closes the fluid dosing unit if no container is connected to the fluid dosing unit and that opens the fluid dosing unit upon connection of a container to the fluid dosing unit. Thus, undesired spillages potentially arising upon disconnection of the container from the fluid dosing unit can be avoided.

System and method for connecting a concentrate container with a blood treatment device without leakages

The present invention relates to a method of adding an anticoagulant to the blood of a patient, wherein the addition takes place in the form of a bolus, wherein the bolus application time B depends on the values TBV and CO, with TBV representing the blood volume of the patient and CO the cardiac output of the patient. The present invention furthermore relates to an apparatus for adding a coagulant to the blood of a patient.

The present invention refers to a system and method for opening a concentrate container without the need for a human to directly handle the concentrate container and connecting the concentrate container to a blood treatment device. Aspects of the invention are directed to a container for concentrate and a blood treatment device.

System and method for opening a concentrate container and connecting the concentrate container to a blood treatment device

The present invention relates to a method for checking a dialyzer for the presence of a leak in the semipermeable membrane of the dialyzer, wherein the membrane divides the inner dialyzer space into a least one blood chamber and into at least one dialyzate chamber, wherein the blood chamber is flowed through by blood in the operation of the dialyzer and is in fluid communication with a blood-side line system and the vascular system of the patient, and wherein the dialyzate chamber is flowed through by dialysis fluid in the operation of the dialyzer and is in fluid communication with a dialyzate-side line system, wherein the method comprises the following steps:

A container includes a dry concentrate designed such that the dry concentrate forms an acid liquid concentrate, or a part of an acid liquid concentrate, which is suitable for manufacturing a dialysis solution, on the dissolution of the dry concentrate in a liquid, preferably in water.

Container, use, dialyzer or preparation unit as well as method of manufacturing a concentrate

The invention relates to a hose clamp for a blood treatment device, wherein the hose clamp has a housing () and an electromagnetically driven compression piece (), with the electromagnetic drive of the compression piece () being configured such that the compression piece () is opened against a mechanical restoring force (A) in a state of the hose clamp with an applied current and is closed by the mechanical restoring force (A) in a currentless state of the hose clamp; wherein the hose clamp has, in addition to the electromechanical drive, a mechanical actuator () with which the compression piece () can be opened manually against the mechanical restoring force (A) in the currentless state of the hose clamp; and wherein the contact elements () of the actuator () and of the compression piece () are configured such that they form a mechanical connection between the actuator () and the compression piece () after an opening of the compression piece () in the currentless state, said connection preventing another closing of the compression piece () in the currentless state of the hose clamp by the mechanical restoring force (A) and being released in the state of the hose clamp with an applied current.

The present invention relates to extracorporeal blood treatment devices and methods and devices for conserving extracorporeal blood treatment devices. In accordance with the present invention, an antifreeze agent in introduced only into that part of the dialysis liquid system of the blood treatment device that includes the volume lying upstream of a sterile filter with which sterile substituate is recovered from the dialysis liquid. Accordingly, that part of the dialysis liquid system that includes the volume lying downstream of the sterile filter is not filled with an antifreeze agent. The present invention makes it possible, after removal of the sterile filter, to easily and safely separate a substituate segment from the rest of the dialysis liquid system and drain off liquid located in the substituate segment.

A chamber for a blood treatment system having a blood inlet and a blood outlet, a filter element for air separation which is arranged at the head side with respect to the position of the chamber in the operating state, and which can be decoupled from the blood present in the chamber in the operating state via a further liquid.

Chamber for a blood treatment system, blood tubing system, and blood treatment system

A tubing set suitable for use in co-operation with a hemodialysis machine includes an out-tube for supplying the blood from the patient to a filter of the machine, an in-tube for supplying the blood from the filter back to the patient, a drip chamber placed along one of the tubes, adapted to let the blood drip through an air buffer, and a vial gate for the connection of vials containing drugs to be delivered into the blood. The vial gate includes a delivery lumen, suitable for delivering the drug from the vial to the drip chamber, and a vent lumen, suitable for providing air inside the vial in order to replace the delivered drug.

Tubing set having a gate for the connection of vials

A device for monitoring an extracorporeal blood circuit of an extracorporeal blood treatment device for detection of air bubbles in blood that is conveyed in the extracorporeal circuit by a blood pump, and a method for monitoring an extracorporeal blood circuit for detection of air bubbles, together with a device for monitoring the extracorporeal blood circuit are described. The device and method are based on monitoring the negative pressure in the extracorporeal blood circuit upstream of the blood pump, to allow differentiation between the occurrence of microbubbles which are attributable to cavitation and an entry of air not due to cavitation. When the negative pressure is above a predetermined limit value and microbubbles are detected in the extracorporeal blood circuit, it is deduced that the microbubbles are produced by cavitation and the mechanisms for dissolving the microbubbles are insufficient to remove the microbubbles again before they could reach the patient.
