Abstract: A method and device for determining the concentration of blood constituents, in particular haemoglobin, in a hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, and an extracorporeal blood treatment apparatus with a device for determining the concentration of a blood constituent, are based on the correction of the influence of the blood flow rate of the blood flowing through the hose line on the determination of the concentration of the blood constituent. The device comprises a computing and evaluation unit configured such that a correction factor is ascertained for the influence of the blood flow rate on the determination of the concentration of the blood constituent. The concentration of the blood constituent is then determined based on a relationship describing the dependence of the concentration of the blood constituent on the intensity of the decoupled electromagnetic radiation, taking account of the correction factor.

Abstract: A device for determining the concentration of a constituent of blood in a hose line, in particular in the hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, includes a clamping unit having an actuation mechanism configured to apply a clamping force such that first and second receiving elements are moved towards one another from a first position releasing the hose line into a second position clamping the hose line, in which the drive of the actuation mechanism takes place with an electric motor, and a monitoring unit configured to detect a hose line inserted into the receiving elements. A method for detecting a hose line in a clamping unit of a device for determining the concentration of a blood constituent in the hose line is also described. Automation of the measurement of the blood parameters is thus possible.

Abstract: A dialyser has assigned thereto a measuring unit that transmits data to the dialyser via a wireless link, the measuring unit being able to determine and transmit to the dialyser at least one measurable variable which can also be determined by another measuring device that is connected physically to the dialyser, a comparison of the at least one measurable variable as determined by the measuring unit and by the measuring device indicating whether the measuring unit is indeed the one assigned to the dialyser in question and/or whether the measuring unit is working properly.

Abstract: A method for determining the recirculation in a fistula and/or the cardiopulmonary recirculation part during an extracorporeal blood treatment is disclosed, where the blood to be treated flows in an extracorporeal blood circuit through a blood chamber of a dialyzer split by a semi-permeable membrane into the blood chamber and a liquid chamber, and dialysis liquid flows in a dialysis liquid path through the dialysis liquid chamber of the dialyzer. A device for determining the recirculation in a fistula and/or the cardio-pulmonary recirculation part, and a blood treatment device including such a device are also disclosed. The method and device are based on the fact that the sum of the fistula recirculation and the cardiopulmonary recirculation part, i.e. the total recirculation, is determined for two blood flow rates which differ from each other. The fistula recirculation and/or the cardiopulmonary recirculation part are then determined from the recirculation for the two blood flow rates.

Abstract: The present invention relates to a method for detecting at least one characteristic relating to a patient's glucose metabolism, having steps to be performed during an extracorporeal treatment of the patient's blood, particularly during a dialysis treatment, of the extracorporeal addition of glucose and/or insulin and extracorporeal measurement of a glucose concentration and/or an insulin concentration. The invention further proposes a corresponding device. In addition, the invention proposes a method for determining the composition of the dialysate for the extracorporeal treatment of a patient's blood having the steps of determining a glucose level in the patient's blood during the dialysis session and adapting the amount of glucose added to the dialysate or blood based on the glucose level determined. To this end, the invention proposes a corresponding device. The invention further proposes a blood treatment device.

Abstract: An assembly includes at least two medical treatment units, each of which can be allocated to a patient and at least two peripheral devices, each of which can be allocated to a patient. The peripheral devices and the treatment units have means for allocating a peripheral device to a treatment unit and means for verifying the allocation of a peripheral device to a patient. To allocate a peripheral device to a treatment unit, the peripheral device is placed by operators in a receiving unit belonging to the treatment unit. Said receiving unit is preferably designed as a charging station for the battery of the peripheral device. In the event of a successful allocation of peripheral device and patient, confirmed by the receipt of physiological data of the patient, the operators verify the correct allocation of a peripheral device to the patient and must confirm the correct allocation by confirmation means.
