A SYSTEM AND METHOD FOR PROVIDING CLOSED LOOP INFUSION FORMULATION DELIVERY

摘要

A system and method for providing closed loop infusion formulation delivery which accurately calculates a delivery amount based on a sensed biological state by adjusting an algorithm's programmable control parameters. The algorithm calculates a delivery amount having proportional, derivative, and basal rate components. The control parameters may be adjusted in real time t o compensate for changes in a sensed biological state that may result from dai ly events. Safety limits on the delivery amount may be included in the algorith m. The algorithm may be executed by a computing element within a process controller for controlling closed loop infusion formulation delivery. The biological state is sensed by a sensing device which provides a signal to th e controller. The controller calculates an infusion formulation delivery amoun t based on the signal and sends commands to an infusion formulation delivery device which delivers an amount of infusion formulation determined by the commands.
