  • Patent number: 10384004
    Abstract: Processes for operating an infusion pump are provided for pumping fluid though an administration set at a constant flow rate. The pump includes a pumping mechanism for pumping fluid and operates at a pulse frequency, and a controller controls the pulse frequency. Additionally, the pump has one or more sensors configured for measuring at least one characteristic value relating to a status of the infusion pump. The controller is configured for causing the pumping mechanism to operate at a first pulse frequency, and the one or more sensors measure the characteristic value. When the measured characteristic value meets a threshold value, the controller causes the pumping mechanism to operate at a second pulse frequency different from the first pulse frequency.

  • Patent number: 10157266
    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.
