(54) Title: VOLUME-BASED FLOW RATE COMPENSATION TECHNIQUE FOR INFUSION THERAPY (57) : An infusion pump is provided for pumping fluid through an administrative set at a desired flow rate over a specified duration, and includes a pumping mechanism for 12 releasably receiving and for exerting a pulsing force on the administrative set, thus pres- surizing a portion of the set for creating a flow of fluid from a set outlet. A controller is connected to and is configured for operating the pumping mechanism, the controller deter- mines a pulse frequency based on a volume of fluid infused over a portion of the specified duration and the desired flow rate, outputs a control signal to the pumping mechanism for 18 operating the pumping mechanism based on the determined pulse frequency, determines a first pulse frequency based on the desired flow rate; and adjusts the first pulse frequency 16 based on the volume of fluid infused to provide a second pulse frequency being different from the first pulse frequency. 14 [Continued on next page] WO 2018/148427 Al MIDEDIMOMMIDEFIE3010IFINDIOHNEVOIS Published: — with international search report (Art. 21(3))
