  • Patent number: 10943686
    Abstract: An infusion map system includes a memory storing at least infusion mapping instructions, and a processor that executes the stored instructions. When the processor executes the infusion mapping instructions, the infusion map system performs a displaying function that displays at least a portion of an electronic medical record associated with a patient and a diagramming function that receives the electronic medical record and generates an infusion map showing all intravenous drugs being administered to the patient. For each of the drugs, the infusion map further illustrates a route of administration for the drug. An order administering function performed by the system allows a user to alter the infusion map, and a record updating function of annotating the electronic medical record to correspond to the altered infusion map.
