Abstract: A container for dialysis concentrates, in particular acidic dry concentrates, has integral supporting elements. When these dry concentrates are dissolved directly by a dialysis machine to form liquid concentrates, the container must provide a volume of 4-12 liters. To impart the required stability to the container, the container includes the integral supporting elements, which manifest their supporting function only when the container is used on the dialysis machine.

Abstract: A hemodialysis machine or hemodiafiltration machine is provided that may be used directly for sampling for the connection to a hemodialyzer or for providing replacement fluid, as is required for regular microbiological testing. The machine does not require any additional components or any complex hygiene measures to prevent secondary contamination. By connecting an inventive sterile sampling set, samples can easily be taken. Closing elements and pumping mechanisms are controlled by a control unit as part of a sampling control program.

Abstract: The present invention relates to an extracorporeal blood treatment device comprising a treatment unit and a device for controlling the treatment unit for preparing and carrying out the blood treatment. The blood treatment device also comprises an internal communication unit for communicating with an external communication unit. In order to the prepare the device blood treatment, the patient sends an initiation code by means of an external communication unit to the internal communication device. Routines required for preparing the blood treatment are then started. One main advantage is that the patient, for example during home dialysis, does not need to be present when the device is preparing for dialysis and the dialysis preparation can be started when the patient thinks of returning home in time for the beginning of the preparation phase.

Abstract: The present invention relates to a method and a device for monitoring a flowing medium, in particular the blood flowing in an extracorporeal blood circulation, for the presence of air, in particular micro-bubbles. A sequence of signal pulses or a continuous signal is injected into the flowing medium, and the signal pulses or continuous signal leaving the flowing medium are received. To detect micro-bubbles, a signal pattern that is characteristic of the variation over time of the received signal pulses or the continuous signal in a predetermined period of time is extracted from the signal received. The characteristic signal pattern is compared with one or more characteristic reference patterns, and the presence of air bubbles is determined if the characteristic signal pattern deviates from the characteristic reference pattern by a predetermined amount. Statistical characteristic variables, in particular the variance, are preferably determined from the signal patterns and compared with one another.

Abstract: The invention relates to the field of equipment for renal replacement therapy. It is based on the observation that connections (14, 15, 101) already present in a hemodialysis machine or hemodiafiltration machine (10) may also be used directly for sampling for the connection to a hemodialyzer or for providing replacement fluid, as is required for regular microbiological testing. The invention does not require any additional components on the equipment or any complex hygiene measures to prevent secondary contamination. By connecting an inventive sterile sampling set, samples can easily be taken. On the equipment end, one need only to program the control unit (26) to implement the inventive method by means of corresponding control of the closing means (20, 21, 103) and the pumping mechanisms (17, 18) as part of a sampling control program.

Abstract: In order to detect a leakage in a fluid system of a blood treatment apparatus having an extracorporeal blood circuit, the pressure in the fluid system is measured continuously during a predetermined period of the duration of treatment, and the leak rates are calculated from the change in the pressure at predetermined time intervals of the predetermined period of the duration of treatment. The leakage volume in the predetermined period of the duration of treatment is calculated from the leak rates, and the leakage volume is compared with a predetermined limit value. If the leakage volume is greater than the limit value, this indicates a possible loss of leaktightness in the system. This can be verified with a conventional pressure-holding test. The method and device are characterized by the fact that it is not necessary in principle to interrupt the blood treatment in order to detect a loss of leaktightness.

Abstract: A machine and method for preparing dialysis fluid for a dialysis machine. Fresh water is mixed with one or more dialysis fluid concentrates. The mixture of water and concentrates is conveyed into an equalizing chamber by a proportioning unit at a predetermined flow rate independent of the dialysate flow rate. Metered addition of the concentrates is performed volumetrically and is monitored on the basis of the conductivity of the dialysis fluid, which is measured by conductivity sensors. Because the mixture of water and concentrates is always conveyed at the same flow rate, the composition of the dialysis fluid can be determined with a high accuracy and the proportioning can be performed accurately.
