Detecting leak in liquid system of blood treatment system involves deriving leakage rate from change in pressure in defined intervals, driving leakage volume from leakage rate

摘要

The method involves continuously measuring the pressure in the liquid system over a defined period of the treatment time, deriving the leakage rate from the change in pressure in defined intervals, driving the leakage volume from the leakage rate over the defined period and comparing the leakage volume with a defined threshold value. AN Independent claim is also included for the following: an arrangement for detecting a leak in a liquid system of blood treatment system.
