Abstract:
1. An infusion pump system for infusion of a predetermined medical solution at a preset reference infusion speed, comprising: (A) a medical solution container configured to contain a medical solution; (B) an infusion line via which the medical solution is drawn from the medical solution container; (C) an infusion pump configured to discharge the medical solution via the infusion line from the medical solution container directly into a body of a patient; (D) a reference infusion speed storing unit configured to store a reference infusion speed; (E) a correction coefficient storing unit configured to store a correction coefficient for use in correction of a variation in a discharge speed of the medical solution, the correction coefficient being predefined in accordance with a degree of medical effect of the medical solution; (F) an infusion speed measurement unit configured to measure an infusion speed of the medical solution flowing through the infusion line; (G) a discharge speed computation unit configured for discharge speed computation to compute a discharge speed of the infusion pump for infusion of the medical solution at the reference infusion speed, the discharge speed determined with reference to (i) a current discharge speed of the infusion pump, (ii) the reference infusion speed stored in the reference infusion speed storing unit, and (iii) the infusion speed of the medical solution measured by the infusion speed measurement unit; (H) a discharge speed correction unit configured for discharge speed correction to correct the discharge speed that has been obtained as a result of the discharge speed computation by the discharge speed computation unit, the discharge speed correction being made with reference to (i) the current discharge speed of the infusion pump and (ii) the correction coefficient for the medical solution stored in the correction coefficient storing unit; and (I) a control unit configured to control the infusion pump to make the infusion pump discharge the medical solution at the discharge speed obtained as a result of the discharge speed correction by the discharge speed correction unit.
