Abstract—The design of a new instrument for automatic controlling pressure, but are not able to automatically adjust the inner
the pressure in a medical cuff of catheter was introduced in this pressure inside the ule. In our study, a new system of
paper. This instrument contained several main parts including single automatically adjusting and controlling the pressure in cuff of
chip puter used in main control, pressure sensors, and the catheter is proposed in order to get over the limitation of the
program controlling air pump etc. The pressure sensors transformed above-mentioned existed methods. Our system can facilitate to
pressure signal in cuff to electrical signal, which was then transmitted the clinical treatment and scientific research..
to the single chip puter. Pressure in cuff of catheter was
regulated by the programmable switch which was controlled by the
single chip puter. This instrument had main function of II. DESIGN OF HARDWARE
real-time display and maintaining the pressure in cuff of
