Abstract

Disclosed herein is an ultrasonic barrier chamber for fluid systems, for example, which facilitates making fluid lines airless using ultrasonic signals. In some examples, the fluid lines may include an extracorporeal blood circuit, for instance, for use in a dialysis process. In one example, a device for monitoring an extracorporeal circuit in which a blood pump is disposed to convey blood may include one or more ultrasonic transducers positioned in a predetermined vicinity of a vent of a drip chamber of the extracorporeal circuit, and a controller coupled to the one or more ultrasonic transducers, the controller configured to cause the one or more ultrasonic transducers to emit ultrasonic signals that displace particles in contents of the drip chamber away from the vent. Other embodiments are described.
