<P>PROBLEM TO BE SOLVED: To easily and speedily set an infusion bag, to stabilize pressurization to the infusion bag while increasing exhaust speed, and to accurately detect and display the residual quantity of infusion with a simple mechanism. <P>SOLUTION: This infusion bag pressurizing apparatus has a holder 11 having an infusion bag insertion space 13 of square pole shape and hardly deformed; a pressure bag 12 formed to allow the insertion of the infusion bag 3 and to form a portion extended along two facing internal sidewalls of large area, as an inflatable part inflated by the injection of gas; a pressure means for supplying gas to the inflatable part to pressurize the infusion bag 3; and a pressure sensor for detecting the pressure. A residual quantity display means may be provided for previously storing the rotating time or the like of a pressure pump serving as the pressure means, from the drive start of the pressure pump until infusion is emptied, calculating the residual quantity of the infusion bag 3 using the stored value and a value detected by a pump drive detection means, and displaying the value on a display part 16. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
