Development of a Digitized Medium Frequency Electronic Therapeutic Instrument

Abstract:

In the process of physical therapy, it is usual to stimulate nerves or muscles of body with electrical signals through the electrodes, such as changeable square waves or sine waves, to control the corresponding functions or the action of muscular dilatation so as to relieve the pain of patients. On the basis of recent medical research, bell-like wave and exponential wave are most suitable for use. A digitalized medium frequency electronic therapeutic instrument based on the ARM embedded system is developed. The discrete bell-like wave and exponential wave are generated through the S3C2410 microprocessor, and then the digital signal is converted into analog signal through D/A converting chip. Finally the analog signal is amplified and output through power amplifying and isolated output circuit to generate the curing wave for human body. This method solved the difficulty of generating bell-like curing wave in traditional analog medium frequency electronic curing instrument.
