An ultrasound therapy system for hyperlipidemia prevention

Ultrasound has been widely applied in the field of medical and healthcare. This paper assumes that noninvasive ultrasound reduces blood lipid levels and inhibits thrombosis in vessels. An apparatus with adjustable parameters was designed for ultrasound treatment. The system consists of five parts: ultrasound transducer, waveform generation, matching network, control module and power supply. The apparatus test showed that the system is stable and adjustable. The hyperlipidemia rat models were randomized to control group, medication group (Simvastatin) and ultrasound group (40 KHz, 2.5W/cm2) respectively. The blood lipid concentration of the ultrasound group was lower than the control and medication group (p<;0.05). Noninvasive ultrasonic treatment reduced blood lipid concentration significantly. The animal experiment result preliminary indicated that ultrasound can be a safe and effective method to hyperlipidemia intervention.
