Alarm messages, which are output by a medical apparatus, are remotely processed on a remote application apparatus under consideration of a safety check and in particular with regard to whether the user who is working at the application apparatus is in visual contact with the alarm message-triggering medical apparatus. The medical apparatus may be a hemodialysis apparatus or a peritoneal dialysis apparatus, or another type of medical apparatus.

Remote control of messages for a dialysis apparatus

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.

Method for the determination of at least one characteristic figure relating to a patient's glucose metabolism, and apparatus therefor

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. The peripheral device is only released if the operator has confirmed the correct allocation, preferably within a predefined time period.

Arrangement comprising medical treatment units and peripheral devices as well as a peripheral device and treatment unit for use in such an arrangement

A dialysis device including a dialysis circuit, a blood circuit; and a dialyzer. The dialysis device includes a device for generating a high-frequency electromagnetic field and a device for generating an electrostatic direct current field. Both devices are designed and arranged in such a way that blood to be treated can be exposed to the high-frequency electromagnetic field and the electrostatic direct current field when passing through the dialyzer.

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.

System and method for determining the hematocrit and/or blood volume

A device and method for detecting complications during an extracorporeal blood treatment are provided. During the dialysis treatment, the dialysance or clearance may be continuously determined at successive points in time based on a measured change in a physical or chemical characteristic quantity of the dialysis liquid, for example, the ion concentration of the dialysis liquid. In the event a significant change in the dialysance or clearance is established, the determination of the recirculation may be effected based on a measured change in a physical or chemical characteristic quantity of the blood. When both a significant change in the determined dialysance as well as in the recirculation occurs, a complication may be assumed with regard to a bad vessel access. Alternatively, a complication may be assumed with regard to the dialyzer. The present invention may allow the continuous monitoring during the dialysis treatment to ensue solely on the basis of the change in the measured dialysate-side characteristic quantities.

A device and method for increasing the safety of an extracorporeal blood treatment machine are based on monitoring transmembrane pressure. The transmembrane pressure measured by a measuring device during the treatment is compared with an upper limit transmembrane pressure Land a lower limit transmembrane pressure Lwhich define a monitoring window. If the transmembrane pressure is outside this monitoring window, an alarm is triggered by an alarm device. The monitoring window is shifted as a function of the ultrafiltration rate. To determine the window limits, the transmembrane pressure is established after a change in the ultrafiltration rate is calculated. Thereafter, the window limits are determined on the basis of the expected transmembrane pressure.
