Infusion pump infusion amount detection and control safety system

The utility model relates to an infusion pump infusion amount detection and control safety system which comprises an infusion rod and an infusion pump, a gravity detection module is hung on the infusion rod, an infusion bag is hung below the gravity detection module, the infusion bag is connected with an infusion pump pipeline through a drip cup, and signals generated by the gravity detection module are connected with the infusion pump in a wired or wireless mode. According to the infusion pump, the actual infusion amount is detected by detecting the weight change of the infusion bag, information is fed back to the infusion pump, and when software calculation finds that the weight change of the infusion bag is too slow or too fast, an alarm is triggered. The infusion set has the advantagesof being simple in structure, low in cost, high in reliability, free of limitation of the shapes of an infusion set and a drip cup, capable of achieving semi-closed-loop control and capable of effectively preventing the risk
