Closed Loop Infusion Formulation Delivery System
First Claim
1. A closed loop infusion formulation delivery system for controlling a biological state in the body of a user, comprising:
- a sensor or plurality of sensors for measuring parameters of a sensed biological state at timed intervals and generating a signal representative of the measured parameters and times at which the measurements are taken;
a computing element for receiving and processing the generated signal, wherein the computing element adjusts control parameters within an algorithm to compensate for changes in the sensed biological state resulting from events affecting the sensed biological state;
calculates a delivery rate of an infusion formulation after adjusting the control parameters; and
generates commands based on the calculated delivery rate;
anda delivery device for receiving the generated commands and delivering the infusion formulation based on the generated commands;
wherein the algorithm receives measured parameters and uses control parameters, the control parameters being different from the measured parameters, andwherein the algorithm is used for calculating an infusion formulation delivery rate; and
a remotely located monitoring station that communicates with the computing element via radio or wire to further adjust the control parameters within the algorithm to meet changing needs in the body of the user or to ensure the safety of the user if an out of protocol state is detected.

Abstract
A closed loop infusion formulation delivery system for controlling a biological state in the body of a user includes a sensor for generating a signal representative of measured parameters and a computing element for processing the generated signal. The computing element adjusts control parameters within an algorithm, calculates a delivery rate of an infusion formulation and generates commands based on the calculated delivery rate. A remotely located monitoring station communicates with the computing element via radio or wire to further adjust the control parameters within the algorithm to meet changing needs in the body of the user.
