Design of Closed Circulation Fumigating-washing Instrument of Traditional Chinese Medicine

In order to ensure closed circulation and long time constant temperature in the process of fumigating-washing with the traditional Chinese medicine,and then improve the curative effect,an automatic fumigating-washing instrument was designed.The structure design of the automatic fumigating-washing instrument,hardware design and software design of control system were accomplished to make the instrument have the functions of fumigating,washing and bathing.The function modules of input-output,communication,human-computer interaction and protect were designed for the instrument.Master-slave and two-stage MCU control mode is applied to the control system.The control accuracy for medical solution temperature of the instrument is ±0.5 ℃ obtained by clinical verification while the temperature difference in fumigating-washing room is kept in ±1 ℃.Medical solution can be cyclically used.The system can satisfy the requirement of continuous washing and retain the effect of the traditional Chinese medicine.The application effect shows that the system works stable and the design is reasonable.
