Abstract
A device for carrying fluids for a medical treatment device with two balancing chambers, each having two partial chambers. The filling times of the partial chambers are initially determined using a monitoring device, and then the filling times of the first partial chambers of the first and second balancing chambers, are compared to the filling times of the second partial chambers of the first and second balancing chambers, respectively, to detect leakage or an incomplete filling or discharging of the respective partial chambers.
Claims13
A device for carrying fluids for a medical treatment device comprising:
- two balancing chambers of equal volume, each of said balancing chambers being separated into a first partial chamber and a second partial chamber by a flexible separating wall;
- each of said first partial chambers having at least one first supply line and at least one first discharge line, and each of said second partial chambers having at least a second supply line and at least a second discharge line;
- and
- a monitoring device configured to initially determine filling times of the first partial chambers or of the second partial chambers or both, and to compare the filling times so determined to detect a filling time difference indicating leakage or an incomplete filling or discharging of the respective partial chambers.
A device for carrying fluids for a medical treatment device comprising:
- two balancing chambers of equal volume, each of said balancing chambers being separated into a first partial chamber and a second partial chamber by a flexible separating wall, a volume of each of said first and second partial chambers when completely filled being the same;
- each of said first and second partial chambers having a respective supply line and a respective discharge line controllable by valves so that, for each balancing chamber, as the respective first partial chamber is filled the respective second partial chamber is discharged;
- and
- a monitoring device configured to initially determine filling times of the first partial chambers or of the second partial chambers or both, and to compare the filling times so determined to detect a time difference indicating leakage or an incomplete filling or discharging of the respective partial chambers.
