ABSTRACT:
A fluid debubbler 10 for removing bubbles from fluids such as blood. The debubbler utilizes an ultrasonic transducer 22 to produce low power anisotropic sound waves at about the resonant frequencies of the bubbles to be removed. The sound waves impart a force on bubbles in a fluid chamber 20 so that they will be driven towards a rejected fluid drain 18. Debubbled fluid is removed from the debubbler through an outlet port 16.
