1. A compensation device for setting a flow rate of an infusion solution, obtaining a display gradation to be indicated by a manipulating unit 41 to administer a target flow rate of the infusion solution according to a prescription of infusion solution treatment in an infusion solution set 2 including an infusion solution flow rate controller 40 having display gradations marked within a manipulation range of the manipulating unit 41 to allow for adjustment of the flow rate of the infusion solution as a display gradation indicated by the manipulating unit 41 is varied, the compensation device comprising:

  • an input unit 110 for obtaining an initial gradation indicated by the manipulating unit 41 and an actually measured flow rate obtained by performing measurement while the manipulating unit 41 indicates the initial gradation;

    a memory 130 storing a value for a coefficient C for each display gradation obtained by putting measured values of a contextual variable X and a flow rate Q in a preset equation among a measurable contextual variable X varying depending on an installation state of the infusion solution set 2, a coefficient C varying the display gradation indicated by the manipulating unit 41, and a flow rate Q of the infusion solution administered through the infusion solution set 2;

    a set value calculator 150 putting a value C1 of the coefficient C corresponding to the initial gradation and the actually measured flow rate in the equation to obtain a value X1 of the contextual variable X and then putting the obtained value X1 of the contextual variable X and the target flow rate in the equation to obtain a value C2 of the coefficient C; and

    an output unit 120 outputting a display gradation corresponding to the value C2 of the coefficient C obtained by the set value calculator 150.
