Abstract: A method and a device for recognition of paravasal bleeding upon a supplying of blood to a vascular access via a line and/or upon the removal of blood from a vascular access via a line, particularly paravasal bleeding during extra-corporeal blood treatment, such as for hemodialysis, hemofiltration or hemodiafiltration is provided. A device for extra-corporeal blood treatment, particularly for hemodialysis, hemofiltration or hemodiafiltration, comprising a device for recognition of paravasal bleeding is also provided. The method and the device are based on the change of arterial pressure in the arterial branch or the venous pressure in the venous branch of the extra-corporeal circuit being registered during the extra-corporeal blood treatment. If paravasal bleeding occurs during the blood treatment, the positive dynamic pressure on the line leading to the vascular access rises on the venous cannula during the extra-corporeal blood treatment, or the suction pressure on the line leaving the vascular access, such as the arterial cannula during extra-corporeal blood treatment, rises; that is, the suction pressure becomes more negative. The pressure rise begins moderately at first and then becomes increasingly greater. Decisive for the method and the device, therefore, is that pressure changes that come from a pressure level exhibiting a large difference from the reference value find stronger consideration than those that come from a pressure level that exhibits only a minor difference from the reference value.

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 invention relates to a device and to a method for monitoring access to vessels during extracorporeal blood treatment. The invention forms a loop in the arterial and/or venous line and provides device for fixing a section of the line in a loop. When the line is stressed under tension, the loop contracts and the line finally kinks. The modification of the diameter of the line and the formation of a kink in the line leads to a rise of pressure in the line, which is monitored by a pressure monitoring device. If the pressure exceeds a predetermined threshold value, the aspirating cannula is in danger of slipping out of the vessel access or has partially or completely slipped out, thus allowing the threshold value to be determined for alarms.

Abstract: The invention relates to a process for monitoring the supply of substitution fluid upstream or downstream of a dialyser or filter arranged in an extracorporeal blood stream. One embodiment provides, for the detection of predilution or postdilution, for measuring the pressure in the blood stream downstream of the dialyser or filter, predilution or postdilution being recognized on the basis of the change in pressure following the shutting off and/or starting up of the substituate pump provided for conveying the substitution fluid. Another embodiment provides for recognizing predilution or postdilution on the basis of the comparison of the oscillating pressure signal attributable to the substituate pump to a characteristic reference signal. The characteristic reference signal to which the pressure signal of the substituate pump is compared is preferably the oscillating pressure signal of a blood pump arranged in the blood stream for conveying the blood upstream of the dialyser or filter. In addition, the invention relates to an extracorporeal blood treatment device with a facility for detecting predilution or postdilution, which device operates according to the processes detailed above.

Abstract: The present invention relates to a method for regulating supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. Moreover, the present invention relates to an extracorporeal blood treatment apparatus having a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.

Abstract: The invention relates to a method and a hemodialysis machine for at least partial emptying of an extracorporeal blood circulation after the blood of a patient in the extracorporeal blood circulation has been returned to the patient with the help of an infusion liquid which displaces the blood and after the patient has been separated from the extracorporeal blood circulation. The object of the invention is to empty at least the blood chamber of a hemodialyzer (1) that is subdivided by a semipermeable membrane (2) into a blood chamber (3) and a dialysis fluid chamber (4) without additionally connecting the arterial blood line (5) and the venous blood line (7) of the extracorporeal blood circulation to one another. To do so, the arterial blood line (5) is actively or passively aerated at a first point (50) and/or the venous blood line (7) is actively or passively aerated at a second point (40) and the liquid is emptied through the semipermeable membrane (2) into the dialysis fluid chamber (4) and a dialysis fluid discharge line (21) leaving this chamber. The inventive method can take place here through a control program that runs automatically in the control unit (30) of a hemodialysis machine without requiring special operating steps by the operating person after activation of the program.

Abstract: The invention relates to a method and to a device for operating an electric peristaltic hose pump, in particular a hose pump for transporting fluids in medical-technical devices, in particular extracorporeal blood treatment devices. In order to monitor the regular operation of a hose pump, the power consumption of the pump or a physical variable in correlation with the power consumption, in particular the pump flow, is monitored. The pump flow includes a periodically non-altering direct component which is superimposed on a periodically altering alternating component. In order to monitor the regular operation of the hose pump, the alternating component of the power consumption in relation to the direct component of the power consumption is monitored as whether it increases and/or decreases during blood treatment.
