Abstract
A blood processing assembly includes a centrifuge contained within a heated housing or chamber. A fail safe spill or splash detector is located within the inner wall of the housing. The detector includes a pair of parallel electrodes separated from each other from a small gap. The circuit detects a splash or droplet of liquid which conducts current between the electrodes.
