The paper expatiated the work principle,general project,and the control part of the corresponding program of the temperature system in the gallstone dissolving instrument.Gallstone dissolving instrument adopts automatic control solvent cycle of direct solution stone treatment,replacing the traditional external shock wave rock row stone and gallblad-der surgery method.PID control system to realize the gall stone solvent temperature intelligent control,the basic principle of work is as solvent temperature below the set temperature,the relay control heater to solvent to be heated,conversely,no heating,achieve better able to dissolve the the rapeutic effect of gallstones.
The paper expatiated the work principle, general project, and the control part of the corresponding program of the temperature system in the gallstone dissolving instrument. Gallstone dissolving instrument automatic control solvent cycle of direct solution stone treatment, replacing the traditional external shock wave rock row stone and gallblad-der surgery method. PID control system to realize the gallstone solvent temperature intelligent control, the basic principle of work is as solvent temperature below set temperature, the relay control heater to solvent to be heated, conversely, no heating, achieve better able to dissolve the the rapeutic effect of gallstones.
