一、引言半导体針疗器是按照中医电針疗法的临床要求而研制的,是一种用晶体管制成的小功率高压脉冲医疗器械。电針疗法是祖国医学宝貴遺产針灸疗法的进一步发展。在电針疗法中应用高电压、小电流的脉冲,已經証实对小儿麻痹症、风湿性关节炎等百余种疾病有显著的疗效。本文介紹的三种可供电針疗法使用的晶体管針疗器,电路結構簡單,元件不多,制作容 I. INTRODUCTION Semiconductor needle therapy device is developed according to the clinical requirements of traditional Chinese medicine electro-acupuncture therapy. It is a kind of low-power high-voltage pulse medical device made of transistor. Electroacupuncture is a further development of acupuncture therapy, a precious heritage of motherland medicine. The application of high voltage, low current pulses in electroacupuncture has proven to have significant efficacy against more than 100 diseases such as polio and rheumatoid arthritis. This article describes the three kinds of needle acupuncture can be used for the transistor needle therapy device, the circuit structure is simple, small components, production capacity
