Method And Apparatus For Blood Vessel Needle Dislodgment Detection

Abstract: Disclosed is a method for blood vessel needle dislodgment detection, which comprises the step of carrying out a blood treatment and/or an analysis on a patient (104) using a blood analysis loop (102) at a predefined blood flow and the step of recording at predefined time intervals blood line pressure datasets (202) using a blood line pressure sensor (108) of the blood analysis loop (102). The method comprises further the step of filtering the recorded blood line pressure datasets (202) using a processor, which is configured to filter the recorded datasets using a predefined filter function and the step of testing the filtered blood line pressure datasets using the processor, which is further configured to test the filtered blood line pressure datasets (202) based on a test function. A potential blood vessel needle dislodgment (618) is than detected based on a detecting function resulting from the testing step. Finally, the potential blood vessel needle dislodgment (618) is confirmed or disproved by a static blood line pressure measurement performed by stopping the blood flow and keeping a blood line of the blood analysis loop (102) not isolated from the patient (104).
