Method and device for monitoring a fluid system of an extracorporeal blood treatment device |
摘要 |
The present invention relates to a method and a device for monitoring a fluid system of an extracorporeal blood treatment device. In the method according to the present invention and the device according to the present invention, the pressure in a ventilation line branching off the venous drip chamber in the venous blood line is measured, a hydrophobic filter being disposed in the ventilation line. A fault in the fluid system is determined in the absence of pressure variations in the segment of the ventilation line remote from the venous drip chamber. The pressure variations in the ventilation line can be generated downstream of the hydrophobic filter by alternately ventilating the ventilation line that is closed downstream of the hydrophobic filter during blood treatment. |
