A patent information pushing method when the remaining amount of a drip is monitored. The method comprises: recording information about the stock amount of a drug liquid in a current drip of a transfusion patient and information about the remaining amount of a drug liquid set thereby (S101) reading the information about the stock amount of the drug liquid in the current drip of the transfusion patient and the information about the remaining amount of the drug liquid set thereby (S102) determining whether the stock amount of the drug liquid in the current drip of the transfusion patient is less than a set remaining amount of the drug liquid (S103) if not, it is thought that there is still a sufficient amount of drug liquid, and transfusion can be continued (S104) and if so, sending prompt information to a nurse station to prompt a nurse to change a dressing or withdraw a needle, and pushing patent information (S105). The method prevents the occurrence of the phenomenon where a needle is not withdrawn in time when the transfusion of drug liquid is completed, thereby improving the work efficiency of a hospital. Further disclosed is a corresponding intelligent calling system.La présente invention concerne un procédé de poussée dinformations de brevet lorsque la quantité restante dune perfusion est surveillée.
