【摘要】 通过对人体和体外实验模型进行“超音频”单向脉冲电(脉宽为2μs,重复频率66KHz)和直流电离子导入对比观察,结果证明当两者电流平均值相等时离子导入量相似,但“超音频”单向脉冲电对人体几乎没有刺痛感,优于直流电离子导入法.更多还原

【Abstract】 Iontophoresis with ulttraaudio-frequency current (pulse width: 2μs, frequency: 66 KHz) and direct current were investigated through human body and experimental model. The results indicate that the amount of ion permeated were similar when the average current of them is the same and that the ultra audiofrequency showed no pain.更多还原
