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:
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 is provided. A device for extracorporeal blood treatment 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 extracorporeal blood treatment. One aspect of the method and the device is that pressure changes that come from a pressure level exhibiting a large difference from a reference value are more strongly considered than those that come from a pressure level that exhibits only a minor difference from the reference value.
Abstract:
The invention further relates to an apparatus and method for monitoring a peristaltic hose pump, in particular a peristaltic hose pump of an extracorporeal blood treatment device. The power consumed by the pump and/or the pressure in the tubing segment upstream or downstream of the pump is/are measured during operation of the pump and test signals I1(t), I2(t) which are associated with the individual displacement members are determined. The power or pressure signals associated with the individual displacement members significantly differ from each other during abnormal operation of the hose pump, but no significant differences can be recognized during normal operation of the pump.

Abstract:
A dialysis machine for the removal of toxic substances from biological fluids with agents for the decalcification of a dialysis liquid circulation is disclosed. The dialysis machine allows measurement of the degree of calcification of the dialysis liquid through the use of a blood leak detector or by measuring the dialysis machine pump flow or pump voltage. The invention also includes a process for automatically decalcifying the dialysis liquid circulation when a predetermined degree of calcification of the dialysis machine is measured.
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:
The present invention relates to the field of blood treatment machines such as hemodialysis machines. The object of this invention is to improve upon a generic blood treatment machine such that a certain individualization of the treatment station with little or no expenditure of materials is made possible in order to make the treatment environment more pleasant for the patient to be treated on the machine. The inventive blood treatment machine (10) therefore includes a control unit (16) that is configured so that image files transmitted and/or indexed via a data interface (15) can be displayed on the display screen (13) of the blood treatment machine during a blood treatment. The present invention also includes an external memory means (20) for connection to the data interface (15) and a combination consisting of the blood treatment machine (10) and the external memory means (20).
Abstract:
A method for determining the hematocrit and/or blood volume during an extracorporeal blood treatment with an extracorporeal blood circuit, in which blood is taken with a blood pump via an arterial cannula and an arterial flexible-tube line and blood is fed back via a venous flexible-tube line and a venous cannula. Pressure is measured in the extracorporeal blood circuit and a change in the hematocrit is determined from a change in the pressure. The respective relationship between hematocrit HKT or blood volume RBV and pressure P in the extracorporeal circuit is stored for various cannula diameters and various blood-flow values. The respective relationship for a given cannula diameter and blood flow is selected. The hematocrit and/or blood volume is determined taking account of the selected relationship.
Abstract:
The present invention relates to a blood tube section for extracorporeally carrying blood during a blood treatment of a patient, wherein the blood tube section comprises at least one device for conveying blood, a drug solution or a liquid mixture within the blood tube section by deforming the tube diameter and sliding along an area of the blood tube section. The present invention further relates to an extracorporeal blood circuit, a treatment apparatus as well as methods for conveying blood, a drug solution or a liquid mixture and for supplying and/or administering and/or transporting an active substance.
