Abstract
A programmable infusion pump and controller for automatically determining the interval between pump activations necessary to produce a substantially linear rate of increase or decrease in fluid flow, during the administration of fluids to a patient. The infusion pump contains a user interface, with a keyboard to enter infusion volume, infusion period, and taper period. When the pump is turned on, the previous infusion parameters are retrieved from non-volatile memory. If the user attempts to alter the infusion parameters so as to violate the 'rate too high' or 'rate too low' criteria of the system, an alarm sounds and the user interface displays the 'next best answer' possible. The pump also allows the user to initiate the taper sequence at any time during plateau or continuous fluid delivery.
