超声波对血栓消溶率的影响研究

RESEARCH ON THE INFLUENCE OF ULTRASOUND ON THE RATE OF THROMBLYSIS

采用实验方法探讨了超声波这一物理因子对血栓消溶的影响。实验采用 3种不同频率的超声波(1MHz,2 7kHz,2 0kHz) ,在不同超声功率下 ,作用于凝龄不同的血栓 ,研究超声波的频率和声强对血栓消溶率的影响。实验结果表明 :当血栓发生消溶时 ,在超声功率一定的条件下 ,低频血栓消溶率较高频为优 ;当超声频率一定时 ,强场的血栓消溶率较弱场为优 ;同时发现随着血栓凝龄的增加 ,血栓消溶率依次降低。这为用超声治疗血栓类疾病提供了重要的应用基础。

To study the relationship between the frequency and power of ultrasound and the rate of thromblysis of ultrasound. Three different frequencies (1MHz, 27kHz, 20kHz) and different powers and different powers were in thrombi of different ages. The result showed that the rate of thromblysis had a negative correlation with the frequency, thrombus age and a positive correlation with the power.
