ABSTRACT:
A pressure filling method and a filling apparatus which fills a given quantity of liquid medicine, for example, into ampoules under pressure. A controller 8 initially opens open/close valves 13 of filling mechanisms 7 to commence the filling of liquid medicine 3 into ampoules 2 from nozzles 14. The liquid pressure of liquid medicine 3 is measured at a given time interval by a liquid pressure sensor 15, and is input to the controller 8. The controller 8 determines a mean value of liquid pressure at the end of each measurement on the basis of liquid pressures which are input during each measurement from the liquid pressure sensor 15, and calculates a predicted time for completion of filling on the basis of liquid pressures obtained at the end of each measurement. The predicted times for completion of filling thus determined at the end of each measurement are averaged to provide a corrected predicted time for completion of filling. When the time passed since the commencement of filling reaches the corrected predicted time for completion of filling, the controller 8 closes the open/close valves. This allows a variation in the filling of liquid medicine 3 from ampoule to ampoule to be suppressed.
