Abstract: Disclosed are embodiments of electronic intravenous infusion pumps. In some embodiments, a medical infusion pump system can include a plurality of processors that are operationally isolated from each other. Some pump systems can include a modular electromechanical pump driver comprising a plurality of components that can be removed as a unit from within the pump housing without removing the components from each other. Some pump systems can include a handle formed as a unitary structure, the handle not including any portion of the boundary between panels of the pump housing. Some pump systems can include a memory within the pump housing that is configured to contain information about one or more pumping parameters for execution by at least two of the pump drivers. Some pump systems can include a connector configured to separately receive and secure each one of a plurality of different-sized IV pole stands.
