Embodiment Construction

[0033] figure 1 The main components of the blood treatment apparatus are shown in a very simplified schematic representation. In the present example of embodiment, the blood treatment device is a hemodialysis device comprising a dialyzer 1 separated by a semi-permeable membrane 2 into a blood chamber 3 and a dialysis fluid chamber 4 . The inlet 3a of the blood chamber is connected to one end of the arterial blood line 5 into which the blood pump 6 merges, while the outlet 3b of the blood chamber is connected to one end of the venous blood line 7 into which the drip chamber 8 merges. Located at the other end of the arterial and venous blood lines 5, 7 are arterial and venous cannulas (not shown) for connection to the patient. This part of the blood treatment device represents the extracorporeal blood circuit I.

[0034] An example of use of a hemodialysis apparatus with the method according to the invention and the device according to the invention is described below. Howeve...

Abstract

The invention relates to a device and a method for monitoring the connection of a blood treatment unit (1) to the liquid system II of an extracorporeal blood treatment device, wherein the blood treatment unit (1) has an inlet (4a) and an outlet (4b) for connection to the liquid system, and the liquid system has a conduit system with a first conduit section (10b), which is connected to the inlet (4a), and a second conduit section (12a), which is connected to the outlet (4b) of the blood treatment unit (1). The invention further relates to an extracorporeal blood treatment device with a device for monitoring the connection of the blood treatment unit to the liquid system. The device according to the invention and the method according to the invention for monitoring the connection of a blood treatment unit to the liquid system of an extracorporeal blood treatment device are based on measuring the pressure in the liquid system II of the blood treatment device. On the basis of the pressure measurement alone, it is possible to establish whether the connection of the blood treatment unit to the liquid system is in order or not in order.

Description

technical field [0001] The invention relates to a device and a method for monitoring the connection of a blood treatment unit to a fluid system of an extracorporeal blood treatment apparatus, wherein the blood treatment unit comprises an inlet and an outlet for the connection to the fluid system and the fluid system comprises a A first pipeline section of the inlet and a pipeline system connected to a second pipeline section of the outlet. Furthermore, the invention relates to an extracorporeal blood treatment device having a device for monitoring the connection of a blood treatment unit to a fluid system of a blood treatment device, in particular a dialysis fluid system of the blood treatment device. Background technique [0002] Various types of blood treatment apparatus are known. Known blood treatment devices include, for example, hemodialysis, hemofiltration and hemodiafiltration devices. During blood treatment, the patient's blood flows through the blood treatment un...
