Design and Implementation of Cholecystolithiasis Automatically Perfusion-Dissolved Instrument

In view of the difficulty to operate, low efficiency, and easy to leak of the manual perfusion method for dissolving cholecystolithiasis, an automatically perfusion-dissolved instrument is designed. By means of collecting and analysing the pressure data being outputted from pressure sensor in real time, and adjusting speed and direction of peristaltic pumps automatically to control quantity of dissolvent, so as to achieve the goal of litholysis under constant pressure in the gallbladder. The instrument has function of automatic heating and controlling temperature. Double controllers are used in the design, slave computer controls the running of each module of the instrument, and master computer is used to real-time display operation state and set parameters. Experimental results indicate that the system is stable and reliable, and with high efficiency for dissolving cholecystolithiasis, which provides a new and effective method for cholelithiasis medical treatment.
