A dialysis method to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments is disclosed. The method includes determining, via a base unit controller, whether a peritoneal dialysis treatment or an extracorporeal blood treatment is to be performed. If the peritoneal dialysis treatment is to be performed, the method includes operating first software instructions that cause a base unit to use a first fluid stored in a fluid container. If the extracorporeal blood treatment is to be performed, the method includes operating second software instructions that cause the base unit to use a second, different fluid from an online source and selectively move the second, different fluid to a blood treatment unit for use in the extracorporeal blood treatment. The blood treatment unit is operable with the base unit to perform the extracorporeal blood treatment on a patient.

The invention relates to a blood line (108) comprising an infusion site (145) intended to inject into the line a solution, comprising: a first main channel (200) having a first passage section, a second main channel (220) having a second passage section, means for the formation (210) of a turbulence area located downstream from the first main channel, located upstream from the second main channel, these formation means comprising a first fluid passage means (224) defining a reduction (225) in the passage section and whose smallest passage section is smaller than the first passage section and smaller than the second fluid passage section, a secondary channel (230) comprising an inlet (231) for letting in the solution and an outlet (232) in fluid communication with the first main channel or the means for the formation of a turbulence area or the second main channel.

The invention relates to a dialysis machine having an extracorporeal blood circuit, a blood pump, a dialyzer, a venous pressure sensor, a substituate line, and a control unit, wherein the control unit is configured to operate the blood pump in a first operating mode and in a special operating mode and to start the special operating mode after recognition of a trigger event, in which special operating mode a conveying rate of the blood pump is controlled by means of a default value or is regulated to a desired value, which default or desired value is derived from a value determined before the start of the currently started special operating mode or corresponds to said value, wherein the presence of at least one obstacle is polled before the start of the special operating mode, and wherein, on the presence of the obstacle, the start of the special operating mode is blocked or delayed and/or the selection of the default value or of the desire value on the presence of the obstacle differs from the selection without the presence of the obstacle.

Methods and systems for providing continuous renal replacement therapy (CRRT) to a patient are provided. The system includes a hemofiltration unit that provides continuous venovenous hemofiltration (CVVH), a replacement fluid flow regulator configured to regulate the flow of a replacement fluid, an anticoagulant flow regulator configured to pump an anticoagulant, and a blood warmer. The system provides enhanced access to the extracorporeal circuit for blood analysion, infusion of products and/or anticoagulation control. The system may be used to treat patients having renal insufficiency.

The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

A method for extracorporeal blood treatment using a medical device including at least a dialyzer device, with the following steps: start of blood treatment by means of hemodialysis on the basis of default values for the hemodialysis; determination of current values or ratios of at least one blood flow, an ultrafiltration quantity, a substitution quantity or a type of substitution; recording of a therapy progress on the basis of an output signal of a sensor means; determination of a time of formation of a secondary membrane on the dialyzer by determination of a cross rate in the dialyzer device; change from the hemodialysis to a hemodiafiltration with post-dilution after a predetermined period of time has elapsed; and regulation of the substitution quantity during hemodiafiltration with post-dilution. Corresponding tools for carrying out the method are arranged in a device for extracorporeal blood treatment.
