In a haemodialysis machine there is always the possibility of rupture of the dialysing membrane with consequent leaking of blood into the dialysate. To identify this problem an optical blood leak detector is included to detect staining of the dialysate after it leaves the artificial kidney. This is normally an optical device which detects reduction in light transmission through the dialysate in a special cell which causes the machine to indicate that there is a fault, and also causes the machine to fail to a safe condition.

Blood leak detectors are normally an integral part of the haemodialysis machine, but may be a separate device on some machines. The chamber may be disposable on some modern machines.
