High-power ultrasonic transducer for effective hemolysis

Abstract

To realize compact and portable hemolysis devices, a novel ultrasonic transducer with a blood channel is proposed in this study. Thanks to the parabolic reflector, ultrasound is focused on this channel, ensuing high sound pressure for hemolysis. Experiments were performed with various voltage, flow rate, frequency and other parameters in order to verify the feasibility of hemolysis, and finally the hemolysis reached nearly 100% under the conditions of 80Vpp, 0.25mL/min and 1.25MHz.
